GET請求

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

main(List<String> arguments) {
  var url = 'http://httpbin.org/';
  //向指定URL傳送GET請求
  http.get(url).then((response) {
    print("響應狀態： ${response.statusCode}");
    print("響應正文： ${response.body}");
  });
}

程式碼很簡單，效果如下

POST請求

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

main(List<String> arguments) {
  var url = 'http://httpbin.org/post';
  //向指定URL傳送帶引數的POST請求
  http.post(url ,body: 'name=doodle&color=blue').then((response) {
    print("響應狀態： ${response.statusCode}");
    print("響應正文： ${response.body}");
  });
}

這也很簡單，效果如下

展示JSON資料

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

main(List<String> arguments) {
  var url = 'https://api.github.com/users/dart-lang/repos';
  http.get(url ,headers : {'User-Agent':'Dart/1.0(My Dart client)'}).then((response) {
    //解析響應字串，並生成Json物件
    List<String> repos = JSON.decode(response.body);
    //輸出說明字串
 

    var heading = 'Repository | Star count | Fork count';
    print(heading);
    //輸出與說明字串等長的‘=’字串
    print(new List.filled(heading.length, '=').join());
    //迴圈輸出Json物件的指定引數
    for (var repo in repos) {
      print(
          "${repo['name']} | "
          "${repo['stargazers_count']} | "
          "${repo['forks_count']}");
    }
  });
}

先來看看裡面的JSON字串

暈了沒，再看看程式碼執行後展示的部分JSON資料

這樣就好看多了
