Question

嗨，我有3天的时间，但还活着，

这是我在MVC核心中的代码，它使用mvc API Core api项目在本地工作并且由邮递员测试

string Baseurl = "http://api.site.com";

    // GET: CustomerTypes
    public async Task<IActionResult> Index()
    {
        List<CustomerType> empInfo = new List<CustomerType>();
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri(Baseurl);

            client.DefaultRequestHeaders.Clear();
            client.DefaultRequestHeaders.Add("Connection", "Keep-Alive");
            client.DefaultRequestHeaders.Add("Keep-Alive", "3600");
            //Define request data format  
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            //Sending request to find web api REST service resource GetAllEmployees using HttpClient  
            HttpResponseMessage res = await client.GetAsync("/api/customerTypes");
            if (res.IsSuccessStatusCode)
            {
                //Storing the response details recieved from web api   
                var empResponse = res.Content.ReadAsStringAsync().Result;

                //Deserializing the response recieved from web api and storing into the Employee list  
                empInfo = JsonConvert.DeserializeObject<List<CustomerType>>(empResponse);

            }
            //returning the employee list to view  
            return View(empInfo);
        }

这是在mvc api项目的startup.cs中配置

  public void ConfigureServices(IServiceCollection services)
    {
        services.AddCors(options =>
        {
            options.AddPolicy("AllowSpecificOrigin",
                builder => builder.AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader()
                .AllowCredentials()
                );
        });}

 public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        loggerFactory.AddConsole(Configuration.GetSection("Logging"));
        loggerFactory.AddDebug();


        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        // app.UseCorsMiddleware();

        // Shows UseCors with named policy.
        app.UseCors("AllowSpecificOrigin");



        app.UseMvc();
    }

控制API设置[EnableCors（＆＃34; AllowSpecificOrigin＆＃34;）]每个控件

我尝试了很多方法： 1-从本地运行api并通过远程网络呼叫

2-在远程发布api，从本地发布cal

3-通过邮递员远程站点呼叫远程api

所有这一切都不起作用，只有在邮寄人工作的情况下调用本地api

处理请求时发生未处理的异常。

SocketException：远程主机强行关闭现有连接   System.Net.Sockets.Socket.EndReceive（IAsyncResult asyncResult）

IOException：无法从传输连接读取数据：远程主机强行关闭现有连接。   System.Net.ConnectStream.EndRead（IAsyncResult asyncResult）

HttpRequestException：将内容复制到流时出错。   System.Net.Http.HttpContent + d__49.MoveNext（）

对于我的案例，我与主机管理员联系并重置IIS，它对我有用。
