Functions

func CheckRequest

func CheckRequest(instance Auth, r *http.Request) error

CheckRequest 对复杂请求进行签名验证

func CheckURI

func CheckURI(instance Auth, url *url.URL) error

CheckURI 对URI进行鉴权

func Init

func Init()

Init 初始化通用鉴权器

func SignRequest

func SignRequest(instance Auth, r *http.Request, expires int64) *http.Request

SignRequest 对PUT\POST等复杂HTTP请求签名，只会对URI部分、 请求正文、`X-Cr-`开头的header进行签名

func SignURI

func SignURI(instance Auth, uri string, expires int64) (*url.URL, error)

SignURI 对URI进行签名,签名只针对Path部分，query部分不做验证

Types

type Auth

type Auth interface {
	// 对给定Body进行签名,expires为0表示永不过期
	Sign(body string, expires int64) string
	// 对给定Body和Sign进行检查
	Check(body string, sign string) error
}

Auth 鉴权认证

var General Auth

General 通用的认证接口

type HMACAuth

type HMACAuth struct {
	SecretKey []byte
}

HMACAuth HMAC算法鉴权

func (HMACAuth) Check

func (auth HMACAuth) Check(body string, sign string) error

Check 对给定Body和Sign进行鉴权，包括对expires的检查

func (HMACAuth) Sign

func (auth HMACAuth) Sign(body string, expires int64) string

Sign 对给定Body生成expires后失效的签名，expires为过期时间戳， 填写为0表示不限制有效期
