asp.net WebAPI 调用不适用于 Xamarin.Forms [英] asp.net WebAPI call not working from Xamarin.Forms

问题描述

在我将 Id 的类型从 Int 更改为字符串后，我的 Xamarin 不再调用我的 api.但这不能成为原因，在此之前它可以正常工作

My Xamarin dosnt call anymore my api after i change the typ of Id from Int to string. But that can't be the reason, before that it works without any problems

当我使用 Postman 测试端点时，一切正常

When I test the endpoint with Postman, everything works fine

当我调试它时，应用程序一直运行到 API 调用中的响应，然后中断而不显示错误消息.也不例外.

When I debug it, the application runs through to response in the API call and then breaks off without an error message. No exception.

API 调用

public async Task<bool> LoginUser(string username, string password)
    {

        _acc.UserName = username;
        _acc.Password = password;

        var httpClient = new HttpClient();
        var json = JsonConvert.SerializeObject(_acc);
        var content = new StringContent(json, Encoding.UTF8, "application/json");
        **var response = await httpClient.PostAsync("http://192.168.178.41:45472/api/account/Login", content);**

//这里是中断我的 Web API 调用.

//here is the break my Web API dosnt call.

        if (!response.IsSuccessStatusCode)
        {
            return false;
        }

        return true;

    }

我的 DI:

        public async Task LoginUser(string username, string password)
    {

        var result = await _accService.LoginUser(username, password);

        if (result)
        {
            await _navService.NavigateToAsync<Profile_ViewModel>();
        }
        else
        {
            await Application.Current.MainPage.DisplayAlert("nope", "nope", "nope");
        }
    }

我在 ViewModel 中的方法

My method in the ViewModel

        private async void GoLogin()
    {

        var container = ContainerConfig.CreateContainer();
        using (var scope = container.BeginLifetimeScope())
        {
            var GetService = scope.Resolve<IMyUser_Service>();

            await GetService.LoginUser(UserName, Password);
        }

    }
