文本要点

• HTTP Get 请求
• Dart 类方法（或称为：命名的构造函数）
• String 转 JSON

TestModel

import 'dart:convert';

class TestModel {
  String method;
  num number;
  bool isAjax;

  TestModel(this.method, this.number, this.isAjax);

  /**
   * 类方法
   */
  TestModel.fromJSON(jsonObject) {
    if (jsonObject.runtimeType == String) {

      Map<String, dynamic> temp = json.decode(jsonObject);

      if (temp != null) {
        method = temp['method'];
        number = temp['number'];
        isAjax = temp['isAjax'];
      }
    }
  }

}

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

import 'TestModel.dart';

void httpRequest() async {
    var url = 'http://api.muco.vip/test.php?a=1&b=2&c=3';
    http.get(url).then((response) {
      print('内容：${response.body}');

      var temp = TestModel.fromJSON(response.body);
      print('temp method : ${temp.method}');
    });
}
