　　 post := "{"待发送"："json"}"
    fmt.Println(post)
    var jsonstr = []byte(post) //转换二进制
    buffer:= bytes.NewBuffer(jsonstr) 
    request, err := http.NewRequest("POST", api_url, buffer)
    if err != nil {
        fmt.Printf("http.NewRequest%v", err)
        return queryobj, err
    }
    request.Header.Set("Content-Type", "application/json;charset=UTF-8")  //添加请求头
    client := http.Client{} //创建客户端
    resp, err := client.Do(request.WithContext(context.TODO())) //发送请求
    if err != nil {
        fmt.Printf("client.Do%v", err)
        return queryobj, err
    }
