2.引入

go get -u golib.gaore.com/GaoreGo/gaore-common-sdk-go/sdk

或 Go Module

import "golib.gaore.com/GaoreGo/gaore-common-sdk-go/sdk"

3.服务端认证及返回处理

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

这里以beego为例 :

package applications

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"
    "golib.gaore.com/GaoreGo/grlogs"
)

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)
        }
    })
}

服务端返回的响应体为以下结构的json字符流, code,status,msg 这三个字段最好要包含且数据类型要一致 , data 部分为业务内容，自行定义

{
    "code": 1001,
    "msg": "不能为空",
    "status": false,
    "data": {
        ...
    }
}

4.sdk编写

在services目录下以服务归类新建文件夹, 如jedi为短信服务，以 RpcRequest 和 BaseResponse 以基类写好请求子类和响应子类。一个请求接口对应一对请求和响应类。

import "golib.gaore.com/GaoreGo/gaore-common-sdk-go/sdk"

const (
	HOST    = "jedi"  // 如果非全域名会自动补全.gaore.com , 如jedi 会自动补全jedi.goare.com, 也可以打全域名 test.uu89.com
	VERSION = "2020-08-04"
)


type Client struct {
	sdk.Client
}

func NewClientWithAccessKey(accesskey, secrect, source string) (client *Client, err error) {
	client = &Client{}
	err = client.InitWithAccessKey(accesskey, secrect, source)
	return
}

func (c *Client) Test(req *DemoTestRequest) (response *DemoTestResponse, err error) {
	response = CreateDemoTestResponse()
	err = c.DoAction(req, response)
	return
}

请求类，对参数用标签解释, 如 position:"Query" field:"param_1" default:"" ， 有三个字段 position , field, default

• position 为标志该参数为请求体对应的位置， Query query参数, Body post请求体参数, Head请求头参数

• field 解释成参数实际名称

• default 默认值

type DemoTestRequest struct {
    *requests.RpcRequest
    Param1 string `position:"Query" field:"param_1" default:"" `
    Param2 int    `position:"Query" field:"param_2" default:"10086" `
    Param3 bool   `position:"Query" field:"param_3" default:"false" `
}

对应解释成http请求为：

GET param_1=111&param_2=10086&param_3=false

完整示例：

package jedi

import (
    "golib.gaore.com/GaoreGo/gaore-common-sdk-go/sdk/requests"
    "golib.gaore.com/GaoreGo/gaore-common-sdk-go/sdk/responses"
)

// 定义请求体
type DemoTestRequest struct {
    *requests.RpcRequest
    Param1 string `position:"Query" field:"param_1" default:"" `
    Param2 int    `position:"Query" field:"param_2" default:"10086" `
    Param3 bool   `position:"Query" field:"param_3" default:"false" `
}

func CreateDemoTestRequest() (req *DemoTestRequest) {
    req = &DemoTestRequest{RpcRequest: &requests.RpcRequest{}}
    // InitWithApiInfo 初始化请求，有三个参数，域名，版本，和路径
    // 域名参数如果非全域名会自动补全.gaore.com , 如jedi 会自动补全jedi.goare.com, 也可以打全域名 test.uu89.com
    req.InitWithApiInfo(HOST, VERSION, "/api/sms/Index")
    // 定义 请求方法 POST 或 GET
    req.Method = requests.GET
    return
}

// 定义响应体
type DemoTestResponse struct {
    *responses.BaseResponse
    Data DemoTestResponseData `json:"data"`
}

type DemoTestResponseData struct {
    Account string `json:"account"`
    Total   int    `json:"total"`
}

func CreateDemoTestResponse() *DemoTestResponse {
    return &DemoTestResponse{
        BaseResponse: &responses.BaseResponse{},
    }
}

终端调试打开方式, 需要在系统环境变量上加入(三选一):

DEBUG=sdk,signer,request
