【Golang·抓包】简单抓包代码生成工具的使用实例

关于抓包的代码生成，我将依次示例演示两个网站

• 请求的代码生成
  https://curlconverter.com/go/

• 响应的反序列化
  https://oktools.net/json2go

我们对李白的词条的人物关系尝试抓包

1. 我们找到https://baike.baidu.com/starmap/api/gethumanrelationcard?lemmaId=1043&lemmaTitle=%E6%9D%8E%E7%99%BD这个URL
2. 右键Copy -> Copy as cURL (bash) ，将该curl请求复制到https://curlconverter.com/go/
   
3. 选择Go标签，下面可见已经生成好Golang的请求体代码
   
4. 复制response中的dict到https://oktools.net/json2go
   
   
   右侧即为自动生成的结构体
5. 将结构体和响应体代码整合可得到完整抓包程序

package main

import (
	"encoding/json"
	"fmt"
	"io/ioutil"
	"log"
	"net/http"
)

type Demo struct {
	Errno  int    `json:"errno"`
	Errmsg string `json:"errmsg"`
	List   []struct {
		RelationName string `json:"relationName"`
		LemmaID      int    `json:"lemmaId"`
		LemmaTitle   string `json:"lemmaTitle"`
		CoverPic     string `json:"coverPic"`
		Summary      string `json:"summary"`
	} `json:"list"`
	Info struct {

	} `json:"info"`
}
