Golang发送POST请求并传递JSON数据

客户端

)func main() {// Create a Resty Clientclient := zdpgo_resty.New()// 设置字符串resp, err := client.R().SetHeader("Content-Type", "application/json").SetBody(`{"username":"testuser", "password":"testpass"}`). // 设置请求SetResult(&common.AuthSuccess{}).                          // 处理结果Post("http://127.0.0.1:3333/")if err != nil {fmt.Println("err:", err)return}fmt.Println(resp.String())// 设置字节resp, err = client.R().SetHeader("Content-Type", "application/json").SetBody([]byte(`{"username":"testuser", "password":"testpass"}`)).SetResult(&common.AuthSuccess{}). // or SetResult(AuthSuccess{}).Post("http://127.0.0.1:3333/")if err != nil {fmt.Println("err:", err)return}fmt.Println(resp.String())// 设置结构体resp, err = client.R().SetBody(common.UserRequest{Username: "testuser", Password: "testpass"}).SetResult(&common.AuthSuccess{}). // or SetResult(AuthSuccess{}).SetError(&common.AuthSuccess{}).  // or SetError(AuthError{}).Post("http://127.0.0.1:3333/")if err != nil {fmt.Println("err:", err)return}fmt.Println(resp.String())
}

请求对象
