请问 go 获取 post 请求返回体的 字符类型为[]uint8, 但是是 xml 的格式，怎么转换成 json

body, err := ioutil.ReadAll(res.Body)
fmt.Println("post send success")
fmt.Printf("type is %T\n", body)
结果：
post send success
type is []uint8
<?xml version="1.0" encoding="utf-8" ?><returnsms>
<errorstatus>
<error>2</error>
<remark>sign 参数错误</remark>
</errorstatus>
</returnsms>

@lewis0xx001
<?xml version="1.0" encoding="utf-8" ?><returnsms>
<errorstatus>
<error>2</error>
<remark>sign 参数错误</remark>
</errorstatus>
</returnsms>
是 string() 后的打印结果

直接打印 body 是
body is []byte{0x3c, 0x3f, 0x78, 0x6d, 0x6c, 0x20, 0x76, 0x65, 0x72, 0x73, 0x69, 0x6f, 0x6e, 0x3d, 0x22, 0x31, 0x2e, 0x30, 0x22, 0x20, 0x65, 0x6e, 0x63, 0x6f, 0x64, 0x69, 0x6e, 0x67, 0x3d, 0x22, 0x75, 0x74, 0x66, 0x2d, 0x38, 0x22, 0x20, 0x3f, 0x
3e, 0x3c, 0x72, 0x65, 0x74, 0x75, 0x72, 0x6e, 0x73, 0x6d, 0x73, 0x3e, 0xa, 0x20, 0x3c, 0x65, 0x72, 0x72, 0x6f, 0x72, 0x73, 0x74, 0x61, 0x74, 0x75, 0x73, 0x3e, 0xa, 0x20, 0x3c, 0x65, 0x72, 0x72, 0x6f, 0x72, 0x3e, 0x32, 0x3c, 0x2f, 0x65, 0x72, 0x7

有没有大佬给个思路呀

这个其实网上一搜 一大堆。

鸟哥那图谁来贴一下？

自己搜：golang xml 解析，网上一抓一大把
