Question

我为我的Web API应用程序设置了IIS。我的Web API中的一个函数调用SOAP Web服务。当我尝试使用我的其他项目调用我的Web API时，它会返回Unable to connect to the remote server错误。

奇怪的是，当我在调试模式下运行我的Web API应用程序时，错误没有显示，并且它按预期工作。

以下是我如何调用Web API的草稿：

static async Task RunAsyncBlogs()
{


   using (var client = new HttpClient())
   {
       client.BaseAddress = new Uri("http://ph-lb-d12/my_webapi/");
       client.DefaultRequestHeaders.Accept.Clear();
       client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/xml"));

       var success = "";

       // HTTP GET
       HttpResponseMessage response = await client.GetAsync("api/Controller/DoAction");

                if (response.IsSuccessStatusCode)
                {

                    success = "yes";
                }
                else
                {
                    success = "no";
                }


    }
 }

接下来，我将通过Web API解决方案调用Web服务：假设GetXMLData是API控制器调用的函数

public XmlDocument GetXMLData()
{

    var xmlRaw = "";
    XmlDocument xmldoc = new XmlDocument();
    WS.Service webService = new WS.Service();

    xmlRaw = webService.DoAction("TEST").OuterXml; //THIS IS WHERE THE ERROR OCCURS

    xmldoc.Load(xmlRaw);

    return xmldoc;

}

假设这一切都在Web API解决方案处于调试模式时有效。但是，当它不是。它返回：

对SOAP Web服务的Web API调用返回＆＃34;无法连接＆＃34;错误
