Question

我有REST API服务。下面是API控制器方法。

public class ExcelUploadController : ApiController
{
    [HttpPost]
    public async Task<HttpResponseMessage> Upload(HttpRequestMessage request)
    {
        if (!request.Content.IsMimeMultipartContent())
        {
            throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
        }

        HttpPostedData postedData = await Request.Content.ParseMultipartAsync();
        ProcessFile postedFile = new ProcessFile(postedData);

        return new HttpResponseMessage(HttpStatusCode.OK)
        {
            Content = new StringContent(postedFile.Process())
        };
    }
  }

返回上传的excel的JSON数据。

下面是我使用RESTSharp的客户端代码

int ReadWriteTimeout = -1;
RestClient restClient = new RestClient("https://restfulservice.domain.com");
RestRequest restRequest = new RestRequest("api/excelupload/Upload");

int readWriteTimeout = restRequest.ReadWriteTimeout > 0
       ? restRequest.ReadWriteTimeout
       : ReadWriteTimeout;

restRequest.ReadWriteTimeout = -1;
restClient.Timeout = -1;
restClient.ReadWriteTimeout = -1;
restRequest.Method = Method.POST;
restRequest.AddHeader("Content-Type", "multipart/form-data");
restRequest.AddFile("content", location);
restRequest.AddParameter("DetailLineNumber", "4");

var response = restClient.Execute<List<ActualsDataViewModel>>(restRequest);

我希望我的客户能够等到服务完成处理。但是客户端没有等待，响应对象为空表示状态码为0。response.Data为null。

如果我在本地主机中运行相同的REST API服务并替换客户端中的以下代码，则它可以正常工作。

 RestClient restClient = new RestClient("http://localhost:5100");

如果服务器（IIS）上正在运行相同的服务，为什么客户端没有在等待响应？

发布答案以节省其他人的时间。我知道了

我在调用REST API之前添加了以下内容。 @Hans Vonn在Unable to read data from the transport connection : An existing connection was forcibly closed by the remote host第二个答案中提出了这个答案。

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;

REST客户端不等待REST API服务
