如何在Dart命令行中执行POST HttpClient [英] How to do POST in Dart command line HttpClient

问题描述

我正在努力把一个能够执行http POST的Dart命令行客户端。
我知道我不能使用dart：html库并且必须使用dart：io

I'm struggling with putting together a Dart command line client capable of doing http POST. I know that I can not use dart:html library and have to use dart:io

开始看起来很简单：

HttpClient client = new HttpClient();
client.getUrl(Uri.parse("http://my.host.com:8080/article"));

问题是：什么是正确的语法和顺序，使 HttpClient

The question is: what is the correct syntax and sequence to make this HttpClient do a POST and to be able to pass a JSON-encoded string into this post?

推荐答案

import 'package:http/http.dart' as http;
import 'dart:convert';

void main() {


  var url = 'http://httpbin.org/post';
  http.post(url, body: JSON.encode({'test': 'value'})).then((response) {
    print("Response status: ${response.statusCode}");
    print("Response body: ${response.body}");
  });
}
