encoding token. **jose2go** provides convenience configuration helpers: `Header(name string, value interface{})` and `Headers(headers map[string]interface{})` that can be passed to `Sign(..)` and `Encrypt(..)` calls. + +Note: **jose2go** do not allow to override `alg`, `enc` and `zip` headers. + +Example of signing with extra headers: +```Go + token, err := jose.Sign(payload, jose.ES256, key, + jose.Header("keyid", "111-222-333"), + jose.Header("trans-id", "aaa-bbb")) +``` + +Encryption with extra headers: +```Go +token, err := jose.Encrypt(payload, jose.DIR, jose.A128GCM, sharedKey, + jose.Headers(map[string]interface{}{"keyid": "111-22-33", "cty": "text/plain"})) +``` + +### Two phase validation +In some cases validation (decoding) key can be unknown prior to examining token content. For instance one can use different keys per token issuer or rely on headers information to determine which key to use, do logging or other things. + +**jose2go** allows to pass `func(headers map[string]interface{}, payload string) key interface{}` callback instead of key to `jose.Decode(..)`. Callback will be executed prior to decoding and integrity validation and will recieve parsed headers and payload as is (for encrypted tokens it will be cipher text). Callback should return key to be used for actual decoding process or `error` if decoding should be stopped, given error object will be returned from `jose.Decode(..)` call. + +Example of decoding token with callback: + +```Go +package main + +import ( + "crypto/rsa" + "fmt" + "github.com/dvsekhvalnov/jose2go" + "github.com/dvsekhvalnov/jose2go/keys/rsa" + "io/ioutil" + "errors" +) + +func main() { + + token := "eyJhbGciOiJSUzI1NiIsImN0eSI6InRleHRcL3BsYWluIn0.eyJoZWxsbyI6ICJ3b3JsZCJ9.NL_dfVpZkhNn4bZpCyMq5TmnXbT4yiyecuB6Kax_lV8Yq2dG8wLfea-T4UKnrjLOwxlbwLwuKzffWcnWv3LVAWfeBxhGTa0c4_0TX_wzLnsgLuU6s9M2GBkAIuSMHY6UTFumJlEeRBeiqZNrlqvmAzQ9ppJHfWWkW4stcgLCLMAZbTqvRSppC1SMxnvPXnZSWn_Fk_q3oGKWw6Nf0-j-aOhK0S0Lcr0PV69ZE4xBYM9PUS1MpMe2zF5J3Tqlc1VBcJ94fjDj1F7y8twmMT3H1PI9RozO-21R0SiXZ_a93fxhE_l_dj5drgOek7jUN9uBDjkXUwJPAyp9YPehrjyLdw" + + payload, _, err := jose.Decode(token, + func(headers map[string]interface{}, payload string) interface{} { + //log something + fmt.Printf("\nHeaders before decoding: %v\n", headers) + fmt.Printf("\nPayload before decoding: %v\n", payload) + + //lookup key based on keyid header as en example + //or lookup based on something from payload, e.g. 'iss' claim for instance + key := FindKey(headers['keyid']) + + if(key==nil) { + return errors.New("Key not found") + } + + return key; + }) + + if err == nil { + //go use token + fmt.Printf("\ndecoded payload = %v\n", payload) + } +} +``` + +### Working with binary payload +In addition to work with string payloads (typical use-case) `jose2go` supports +encoding and decoding of raw binary data. `jose.DecodeBytes`, `jose.SignBytes` +and `jose.EncryptBytes` functions provides similar interface but accepting +`[]byte` payloads. + +Examples: + +```Go +package main + +import ( + "github.com/dvsekhvalnov/jose2go" +) + +func main() { + + token := `eyJhbGciOiJQQkVTMi1IUzI1NitBMTI4S1ciLCJlbmMiOiJBMjU2R0NNIiwicDJjIjo4MTkyLCJwMnMiOiJlZWpFZTF0YmJVbU5XV2s2In0.J2HTgltxH3p7A2zDgQWpZPgA2CHTSnDmMhlZWeSOMoZ0YvhphCeg-w.FzYG5AOptknu7jsG.L8jAxfxZhDNIqb0T96YWoznQ.yNeOfQWUbm8KuDGZ_5lL_g` + + passphrase := `top secret` + + payload, headers, err := jose.DecodeBytes(token,passphrase) + + if(err==nil) { + //go use token + //payload = []byte{....} + } +} +``` + +```Go +package main + +import ( + "fmt" + "io/ioutil" + "github.com/dvsekhvalnov/jose2go/keys/rsa" + "github.com/dvsekhvalnov/jose2go" +) + +func main() { + + payload := []byte {0x01, 0x02, 0x03, 0x04} + + keyBytes,err := ioutil.ReadFile("private.key") + + if(err!=nil) { + panic("invalid key file") + } + + privateKey,e:=Rsa.ReadPrivate(keyBytes) + + if(e!=nil) { + panic("invalid key format") + } + + token,err := jose.SignBytes(payload,jose.RS256, privateKey) + + if(err==nil) { + //go use token + fmt.Printf("\nRS256 = %v\n",token) + } +} +``` + +```Go +package main + +import ( + "fmt" + "io/ioutil" + "github.com/dvsekhvalnov/jose2go/keys/rsa" + "github.com/dvsekhvalnov/jose2go" +) + +func main() { + + payload := []byte {0x01, 0x02, 0x03, 0x04} + + keyBytes,err := ioutil.ReadFile("public.key") + + if(err!=nil) { + panic("invalid key file") + } + + publicKey,e:=Rsa.ReadPublic(keyBytes) + + if(e!=nil) { + panic("invalid key format") + } + + token,err := jose.EncryptBytes(payload, jose.RSA_OAEP, jose.A256GCM, publicKey) + + if(err==nil) { + //go use token + fmt.Printf("\ntoken = %v\n",token) + } +} +``` +### Dealing with keys +**jose2go** provides several helper methods to simplify loading & importing of elliptic and rsa keys.

+另一个比较高级的做法是写入到任何实现 `io.Writer` 接口的对象中： + +```go +// ... +cfg.WriteTo(writer) +cfg.WriteToIndent(writer, "\t") +``` + +### 高级用法 + +#### 递归读取键值 + +在获取所有键值的过程中，特殊语法 `%()s` 会被应用，其中 `` 可以是相同分区或者默认分区下的键名。字符串 `%()s` 会被相应的键值所替代，如果指定的键不存在，则会用空字符串替代。您可以最多使用 99 层的递归嵌套。 + +```ini +NAME = ini + +[author] +NAME = Unknwon +GITHUB = https://github.com/%(NAME)s + +[package] +FULL_NAME = github.com/go-ini/%(NAME)s +``` + +```go +cfg.Section("author").Key("GITHUB").String() // https://github.com/Unknwon +cfg.Section("package").Key("FULL_NAME").String() // github.com/go-ini/ini +``` + +#### 读取父子分区 + +您可以在分区名称中使用 `.` 来表示两个或多个分区之间的父子关系。如果某个键在子分区中不存在，则会去它的父分区中再次寻找，直到没有父分区为止。 + +```ini +NAME = ini +VERSION = v1 +IMPORT_PATH = gopkg.in/%(NAME)s.%(VERSION)s + +[package] +CLONE_URL = https://%(IMPORT_PATH)s + +[package.sub] +``` + +```go +cfg.Section("package.sub").Key("CLONE_URL").String() // https://gopkg.in/ini.v1 +``` + +#### 读取自增键名 + +如果数据源中的键名为 `-`，则认为该键使用了自增键名的特殊语法。计数器从 1 开始，并且分区之间是相互独立的。 + +```ini +[features] +-: Support read/write comments of keys and sections +-: Support auto-increment of key names +-: Support load multiple files to overwrite key values +``` + +```go +cfg.Section("features").KeyStrings() // []{"#1", "#2", "#3"} +``` + +### 映射到结构 + +想要使用更加面向对象的方式玩转 INI 吗？好主意。 + +```ini +Name = Unknwon +age = 21 +Male = true +Born = 1993-01-01T20:17:05Z + +[Note] +Content = Hi is a good man! +Cities = HangZhou, Boston +``` + +```go +type Note struct { + Content string + Cities []string +} + +type Person struct { + Name string + Age int `ini:"age"` + Male bool + Born time.Time + Note + Created time.Time `ini:"-"` +} + +func main() { + cfg, err := ini.Load("path/to/ini") + // ... + p := new(Person) + err = cfg.MapTo(p) + // ... + + // 一切竟可以如此的简单。 + err = ini.MapTo(p, "path/to/ini") + // ... + + // 嗯哼？只需要映射一个分区吗？ + n := new(Note) + err = cfg.Section("Note").MapTo(n) + // ... +} +``` + +结构的字段怎么设置默认值呢？很简单，只要在映射之前对指定字段进行赋值就可以了。如果键未找到或者类型错误，该值不会发生改变。 + +```go +// ... +p := &Person{ + Name: "Joe", +} +// ... +``` + +这样玩 INI 真的好酷啊！然而，如果不能还给我原来的配置文件，有什么卵用？ + +### 从结构反射 + +可是，我有说不能吗？ + +```go +type Embeded struct { + Dates []time.Time `delim:"|"` +

+#### 名称映射器（Name Mapper） + +为了节省您的时间并简化代码，本库支持类型为 [`NameMapper`](https://gowalker.org/gopkg.in/ini.v1#NameMapper) 的名称映射器，该映射器负责结构字段名与分区名和键名之间的映射。 + +目前有 2 款内置的映射器： + +- `AllCapsUnderscore`：该映射器将字段名转换至格式 `ALL_CAPS_UNDERSCORE` 后再去匹配分区名和键名。 +- `TitleUnderscore`：该映射器将字段名转换至格式 `title_underscore` 后再去匹配分区名和键名。 + +使用方法： + +```go +type Info struct{ + PackageName string +} + +func main() { + err = ini.MapToWithMapper(&Info{}, ini.TitleUnderscore, []byte("package_name=ini")) + // ... + + cfg, err := ini.Load([]byte("PACKAGE_NAME=ini")) + // ... + info := new(Info) + cfg.NameMapper = ini.AllCapsUnderscore + err = cfg.MapTo(info) + // ... +} +``` + +使用函数 `ini.ReflectFromWithMapper` 时也可应用相同的规则。 + +#### 映射/反射的其它说明 + +任何嵌入的结构都会被默认认作一个不同的分区，并且不会自动产生所谓的父子分区关联： + +```go +type Child struct { + Age string +} + +type Parent struct { + Name string + Child +} + +type Config struct { + City string + Parent +} +``` + +示例配置文件： + +```ini +City = Boston + +[Parent] +Name =

Keystream blocks are not preserved between calls, +therefore each side must encrypt/decrypt data with the same segmentation. + +Another aspect of this difference is that part of the counter is exposed as +an nonce in each call. Encrypting two different messages with the same (key, +nonce) pair leads to trivial plaintext recovery. This is analogous to +encrypting two different messages with the same key with a traditional stream +cipher. + +This package also implements XSalsa20: a version of Salsa20 with a 24-byte +nonce as specified in http://cr.yp.to/snuffle/xsalsa-20081128.pdf.

Use @FILE as an argument. + - Add post-app and post-cmd validation hooks. This allows arbitrary validation to be added. + - A bunch of improvements to help usage and formatting. + - Support arbitrarily nested sub-commands. + +- *2014-07-08* -- Stable v1.2.0 release. + - Pass any value through to `Strings()` when final argument. + Allows for values that look like flags to be processed. + - Allow `--help` to be used with commands. + - Support `Hidden()` flags. + - Parser for [units.Base2Bytes](https://github.com/alecthomas/units) + type. Allows for flags like `--ram=512MB` or `--ram=1GB`. + - Add an `Enum()` value, allowing only one of a set of values + to be selected. eg. `Flag(...).Enum("debug", "info", "warning")`. + +- *2014-06-27* -- Stable v1.1.0 release. + - Bug fixes. + - Always return an error (rather than panicing) when misconfigured. + - `OpenFile(flag, perm)` value type added, for finer control over opening files. + - Significantly improved usage formatting. + +- *2014-06-19* -- Stable v1.0.0 release. + - Support [cumulative positional](#consuming-all-remaining-arguments) arguments. + - Return error rather than panic when there are fatal errors not caught by + the type system. eg. when a default value is invalid. + - Use gokpg.in. + +- *2014-06-10* -- Place-holder streamlining. + - Renamed `MetaVar` to `PlaceHolder`. + - Removed `MetaVarFromDefault`. Kingpin now uses [heuristics](#place-holders-in-help) + to determine what to display. + +## Examples + +### Simple Example + +Kingpin can be used for simple flag+arg applications like so: + +``` +$ ping --help +usage: ping [] [] + +Flags: + --debug Enable debug mode. + --help Show help. + -t, --timeout=5s Timeout waiting for ping. + +Args: + IP address to ping. + [] Number of packets to send +$ ping 1.2.3.4 5 +Would ping: 1.2.3.4 with timeout 5s and count 0 +``` + +From the following source: + +```go +package main + +import ( + "fmt" + + "gopkg.in/alecthomas/kingpin.v2" +) + +var ( + debug = kingpin.Flag("debug", "Enable debug mode.").Bool() + timeout = kingpin.Flag("timeout", "Timeout waiting for ping.").Default("5s").OverrideDefaultFromEnvar("PING_TIMEOUT").Short('t').Duration() + ip = kingpin.Arg("ip", "IP address to ping.").Required().IP() + count = kingpin.Arg("count", "Number of packets to send").Int() +) + +func main() { + kingpin.Version("0.0.1") + kingpin.Parse() + fmt.Printf("Would ping: %s with timeout %s and count %d", *ip, *timeout, *count) +} +``` + +### Complex Example + +Kingpin can also produce complex command-line applications with global flags, +subcommands, and per-subcommand flags, like this: + +``` +$ chat --help +usage: chat [] [] [ ...] + +A command-line chat application. + +Flags: + --help Show help. + --debug Enable debug mode. + --server=127.0.0.1 Server address. + +Commands: + help [] + Show help for a command. + + register + Register a new user. + + post [] [] + Post a message to a channel. + +$ chat help post +usage: chat [] post [] [] + +Post a message to a channel. + +Flags: + --image=IMAGE Image to post. + +Args: + Channel to post to. + [] Text to post. + +$ chat post --image=~/Downloads/owls.jpg pics +... +``` + +From this code: + +```go +package main + +import ( + "os" + "strings" + "gopkg.in/alecthomas/kingpin.v2" +) + +var ( + app = kingpin.New("chat", "A command-line chat application.") + debug = app.Flag("debug", "Enable debug mode.").Bool() + serverIP = app.Flag("server", "Server address.").Default("127.0.0.1").IP() + + register = app.Command("register", "Register a new user.") + registerNick = register.Arg("nick", "Nickname for user.").Required().String() + registerName = register.Arg("name", "Name of user.").Required().String() + + post = app.Command("post", "Post a message to a channel.") + postImage = post.Flag("image", "Image to post.").File() + postChannel = post.Arg("channel", "Channel to post to.").Required().String() + postText = post.Arg("text", "Text to post.").Strings() +) + +func main() { + switch kingpin.MustParse(app.Parse(os.Args[1:])) { + // Register user + case register.FullCommand(): + println(*registerNick) + + // Post message + case post.FullCommand(): + if *postImage != nil { + } + text := strings.Join(*postText, " ") + println("Post:", text) + } +} +``` + +## Reference Documentation + +### Displaying errors and usage information + +Kingpin exports a set of functions to provide consistent errors and usage +information to the user. + +Error messages look something like this: + + : error: + +The functions on `Application` are: + +Function | Purpose +---------|-------------- +`Errorf(format, args)` | Display a printf formatted error to the user. +`Fatalf(format, args)` | As with Errorf, but also call the termination handler. +`FatalUsage(format, args)` | As with Fatalf, but also print contextual usage information. +`FatalUsageContext(context, format, args)` | As with Fatalf, but also print contextual usage information from a `ParseContext`. +`FatalIfError(err, format, args)` | Conditionally print an error prefixed with format+args, then call the termination handler + +There are equivalent global functions in the kingpin namespace for the default +`kingpin.CommandLine` instance. + +### Sub-commands + +Kingpin supports nested sub-commands, with separate flag and positional +arguments per sub-command. Note that positional arguments may only occur after +sub-commands. + +For example: + +```go +var ( + deleteCommand = kingpin.Command("delete", "Delete an object.") + deleteUserCommand = deleteCommand.Command("user", "Delete a user.") + deleteUserUIDFlag = deleteUserCommand.Flag("uid", "Delete user by UID rather than username.") + deleteUserUsername = deleteUserCommand.Arg("username", "Username to delete.") + deletePostCommand = deleteCommand.Command("post", "Delete a post.") +) + +func main() { + switch kingpin.Parse() { + case "delete user": + case "delete post": + } +} +``` + +### Custom Parsers + +Kingpin supports both flag and positional argument parsers for converting to +Go types. For example, some included parsers are `Int()`, `Float()`, +`Duration()` and `ExistingFile()`. + +Parsers conform to Go's [`flag.Value`](http://godoc.org/flag#Value) +interface, so any existing implementations will work. + +For example, a parser for accumulating HTTP header values might look like this: + +```go +type HTTPHeaderValue http.Header + +func (h *HTTPHeaderValue) Set(value string) error { + parts := strings.SplitN(value, ":", 2) + if len(parts) != 2 { + return fmt.Errorf("expected HEADER:VALUE got '%s'", value) + } + (*http.Header)(h).Add(parts[0], parts[1]) + return nil +} + +func (h *HTTPHeaderValue) String() string { + return "" +} +``` + +As a convenience, I would recommend something like this: + +```go +func HTTPHeader(s Settings) (target *http.Header) { + target = new(http.Header) + s.SetValue((*HTTPHeaderValue)(target)) + return +} +``` + +You would use it like so: + +```go +headers = HTTPHeader(kingpin.Flag("header", "Add a HTTP header to the request.").Short('H')) +``` + +### Default Values + +The default value is the zero value for a type. This can be overridden with +the `Default(value)` function on flags and arguments. This function accepts a +string, which is parsed by the value itself, so it *must* be compliant with +the format expected. + +### Place-holders in Help + +The place-holder value for a flag is the value used in the help to describe +the value of a non-boolean flag. + +The value provided to PlaceHolder() is used if provided, then the value +provided by Default() if provided, then finally the capitalised flag name is +used. + +Here are some examples of flags with various permutations: + + --name=NAME // Flag(...).String() + --name="Harry" // Flag(...).Default("Harry").String() + --name=FULL-NAME // flag(...).PlaceHolder("FULL-NAME").Default("Harry").String() + +### Consuming all remaining arguments + +A common command-line idiom is to use all remaining arguments for some +purpose. eg. The following command accepts an arbitrary number of +IP addresses as positional arguments: + + ./cmd ping 10.1.1.1 192.168.1.1 + +Kingpin supports this by having `Value` provide a `IsCumulative() bool` +function. If this function exists and returns true, the value parser will be +called repeatedly for every remaining argument. + +Examples of this are the `Strings()` and `StringMap()` values. + +To implement the above example we might do something like this: + +```go +type ipList []net.IP + +func (i *ipList) Set(value string) error { + if ip := net.ParseIP(value); ip == nil { + return fmt.Errorf("'%s' is not an IP address", value) + } else { + *i = append(*i, ip) + return nil + } +} + +func (i *ipList) String() string { + return "" +} + +func (i *ipList) IsCumulative() bool { + return true +} + +func IPList(s Settings) (target *[]net.IP) { + target = new([]net.IP) + s.SetValue((*ipList)(target)) + return +} +``` + +And use it like so: + +```go +ips := IPList(kingpin.Arg("ips", "IP addresses to ping.")) +``` + +### Custom help + +Kingpin v2 supports templatised help using the text/template library (actually, [a fork](https://github.com/alecthomas/template)). + +You can specify the template to use with the [Application.UsageTemplate()](http://godoc.org/gopkg.in/alecthomas/kingpin.v2#Application.UsageTemplate) function. + +There are three included templates: `kingpin.DefaultUsageTemplate` is the default, +`kingpin.CompactUsageTemplate` provides a more compact representation for more complex command-line structures, and `kingpin.ManPageTemplate` is used to generate man pages. + +See the above templates for examples of usage, and the the function [UsageForContextWithTemplate()](https://github.com/alecthomas/kingpin/blob/master/usage.go#L198) method for details on the context. + +#### Default help template + +``` +$ go run ./examples/curl/curl.go --help +usage: curl [] [ ...] + +An example implementation of curl. + +Flags: + --help Show help. + -t, --timeout=5s Set connection timeout. + -H, --headers=HEADER=VALUE + Add HTTP headers to the request. + +Commands: + help [...] + Show help. + + get url + Retrieve a URL. + + get file + Retrieve a file. + + post [] + POST a resource. +``` + +#### Compact help template + +``` +$ go run ./examples/curl/curl.go --help +usage: curl [] [ ...] + +An example implementation of curl. + +Flags: + --help Show help. + -t, --timeout=5s Set connection timeout. + -H, --headers=HEADER=VALUE + Add HTTP headers to the request. + +Commands: + help [...] + get [] + url + file + post [] +``` diff --git a/vendor/gopkg.in/alecthomas/kingpin.v2/app.go b/vendor/gopkg.in/alecthomas/kingpin.v2/app.go new file mode 100644 index 000000000..9172d6f62 --- /dev/null +++ b/vendor/gopkg.in/alecthomas/kingpin.v2/app.go @@ -0,0 +1,573 @@ +package kingpin + +import ( + "fmt" + "io" + "os" + "strings" +) + +var ( + ErrCommandNotSpecified = fmt.Errorf("command not specified") +) + +// Action callback executed at various stages after all values are populated. +// The application, commands, arguments and flags all have corresponding +// actions. +type Action func(*ParseContext) error + +type ApplicationValidator func(*Application) error + +// An Application contains the definitions of flags, arguments and commands +// for an application. +type Application struct { + *flagGroup + *argGroup + *cmdGroup + initialized bool + Name string + Help string + author string + version string + writer io.Writer // Destination for usage and errors. + usageTemplate string + action Action + preAction Action + validator ApplicationValidator + terminate func(status int) // See Terminate() + noInterspersed bool // can flags be interspersed with args (or must they come first) +} + +// New creates a new Kingpin application instance. +func New(name, help string) *Application { + a := &Application{ + flagGroup: newFlagGroup(), + argGroup: newArgGroup(), + Name: name, + Help: help, + writer: os.Stderr, + usageTemplate: DefaultUsageTemplate, + terminate: os.Exit, + } + a.cmdGroup = newCmdGroup(a) + a.Flag("help", "Show help (also see --help-long and --help-man).").Bool() + a.Flag("help-long", "Generate long help.").Hidden().PreAction(a.generateLongHelp).Bool() + a.Flag("help-man", "Generate a man page.").Hidden().PreAction(a.generateManPage).Bool() + return a +} + +func (a *Application) generateLongHelp(c *ParseContext) error { + a.Writer(os.Stdout) + if err := a.UsageForContextWithTemplate(c, 2, LongHelpTemplate); err != nil { + return err + } + a.terminate(0) + return nil +} + +func (a *Application) generateManPage(c *ParseContext) error { + a.Writer(os.Stdout) + if err := a.UsageForContextWithTemplate(c, 2, ManPageTemplate); err != nil { + return err + } + a.terminate(0) + return nil +} + +// Terminate specifies the termination handler.
