### 服务端认证调用事例

调用 `auth.UnSign` 方法，提供`*http.Request`请求实例，以及`signer.Signer` 签名器（签名器需要包括凭据）
即可完成整个验签过程 

```go
package main

import (
	"github.com/astaxie/beego"
	"github.com/astaxie/beego/context"
	"golib.gaore.com/GaoreGo/gaore-common-sdk-go/sdk/auth"
	"golib.gaore.com/GaoreGo/gaore-common-sdk-go/sdk/auth/credentials"
	"golib.gaore.com/GaoreGo/gaore-common-sdk-go/sdk/auth/signers"
	
)

func init() {
	// 过滤器
    beego.InsertFilter("/api/*", beego.BeforeRouter, func(context *context.Context) {
        httpRequest := context.Request
		err := auth.UnSign(httpRequest, signers.NewAccessKeySigner(&credentials.AccessKeyCredential{
			AccessKeyId:     "aaaaaa",
			AccessKeySecret: "bbbbbb",
			AccessKeyFrom:   context.Input.Param("access_from"),
		}))

		if err != nil {
			resp := response.NewJsonByDefaultFailed()
			resp.Msg = err.Error()
			resp.Code =  10086

			var (
				hasIndent   = beego.BConfig.RunMode != beego.PROD
			)
			context.Output.Status = 500
			context.Output.JSON(resp, hasIndent,  false)
		}
	})
}
```
