单击按钮时颤动http发布数据

Question

当按下按钮时，我想发送 post 数据“1”或“2”int 值（http 包）。我该怎么做？

我的主页画面是这样的；

  import 'package:http/http.dart' as http;
 
      body: Container(
        child: Column(
          children: [
            TextButton(
              onPressed: () async {
                var url = Uri.parse(
                    'http://test.com/control.php');
                var response = await http.post(url, body: {'status': 2});
                print('Response status: ${response.statusCode}');
                print('Response body: ${response.body}');
              },
              child: Text('Open'),
            ),
            TextButton(
              onPressed: () async {
                var url = Uri.parse(
                    'http://test.com/control.php');
                var response = await http.post(url, body: {'status': 2});
                print('Response status: ${response.statusCode}');
                print('Response body: ${response.body}');
              },
              child: Text('Close'),
            ),
          ],
        ),
      ),

对不起我的英语，谢谢你的帮助！

你可以这样做。

final body = jsonEncode({'status': 1});

final url = Uri.http('http://test.com', 'control.php');

final response = await http.post(
    url,
    headers: {'Content-Type': 'application/json'},
    body: body
    );
