Question

这是我的应用为了登录用户而执行的第一个请求。在android上，每个请求都可以正常运行，但是由于某种原因，在iOS上，它们似乎未执行。我已经在模拟器上设置了开发人员选项，以允许HTTP服务。我还在物理iPad上测试了该代码，它将无法执行请求。

在测试期间，我没有为此使用任何超时，并且如果触发请求后我让代码运行一段时间，则会收到此日志（它可能与此无关，但由于我不知道是什么，我也会附上它）：

[C1.1 958047F2-81ED-4A34-AEDE-A23D2CD6B49F 172.20.129.134:51780<->216.58.211.42:443]

bytes in/out: 4769/1077, packets in/out: 9/10, rtt: 0.016s, retransmitted packets: 1, out-of-order packets: 0

代码如下：

Future<LoginResponse> login(String login, String password, AppLocalizations locale) async {

    final response = await http.post(_url, body: {
      "module": _moduleLogin,
      "user": login,
      "pass": password,
      "lang": locale.localeName
    });

    try{
      EventManager manager = EventManager.getInstance();
      manager.clearAllEvents();
    }catch(e){
      print(e);
    }

    if (response.statusCode == 200) {
      return LoginResponse.fromJson(jsonDecode(response.body));
    } else {
      throw Exception('Failed to connect to webservice');
    }}

在这一点上，我不知道是什么导致了这个问题。我正在使用http软件包的最新版本。

这是我扑扑的医生的输出：

Answer 1

想出了一个解决方案，尽管我不知道为什么会起作用。

我将http软件包替换为dio软件包，并且在两个平台上都能正常工作。

Flutter Http请求未在iOS上执行
