与 tencentcloud-sdk-go 集成

概述 #

Req 的 dump 和 debug 日志能力来自其实现的 Transport ，而 tencentcloud-sdk-go 提供了自定义 Transport 的能力，所以我们可以将 Req 的 Transport 集成进 tencentcloud-sdk-go 中，可以使用开关按需打开 debug 能力，看到请求所有细节，以便更方便的调试 API。

代码示例 #

package main

import (
	"fmt"
	"github.com/imroc/req/v3"
	"github.com/tencentcloud/tencentcloud-sdk-go/tencentcloud/common"
	"github.com/tencentcloud/tencentcloud-sdk-go/tencentcloud/common/profile"
	dnspod "github.com/tencentcloud/tencentcloud-sdk-go/tencentcloud/dnspod/v20210323"
	"os"
	"strings"
)

func main() {
	// Read SECRET_ID and SECRET_KEY from env, create dnspod client with tencentcloud SDK.
	credential := common.NewCredential(os.Getenv("SECRET_ID"), os.Getenv("SECRET_KEY"))
	dnspodClient, err := dnspod.NewClient(credential, "", profile.NewClientProfile())
	if err != nil {
		panic(err)
	}
	if os.Getenv("DEBUG") == "true" { // Enable API debug when DEBUG=true.
		// Replace with Transport of req.
		dnspodClient.WithHttpTransport(req.DevMode().GetTransport())
	}

	// Create list domain request and send.
	r := dnspod.NewDescribeDomainListRequest()
	resp, err := dnspodClient.DescribeDomainList(r)
	if err != nil {
		panic(err)
	}

	// Display domain list.
	domains := resp.Response.DomainList
	if len(domains) == 0 {
		fmt.Println("empty domain list")
		return
	}
	list := []string{}
	for _, domain := range domains {
		list = append(list, *domain.Name)
	}
	fmt.Println("\n")
	fmt.Println("-----------------------")
	fmt.Println("domain list:", strings.Join(list, ","))
}

编译并运行:

$ go build -o test
$ export SECRET_ID=AKHD*****************************hiv
$ export SECRET_KEY=g3D2************************5nBR
$ ./test
-----------------------
domain list: imroc.cc,req.cool

打开 Debug，再运行:

$ export DEBUG=true
$ ./test
