Question

我已经搜索过了，但是没有找到答案。我需要使用RestSharp将文件（图像或PDF）上传到WCF REST服务。我已经使用过AddFile（）方法，但是没有找到该服务（我在该方法的第一行添加了一个断点），并且返回的响应为空字符串。

我尝试了byte []和Stream。 Web服务是：

[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json,
    ResponseFormat = WebMessageFormat.Json)]
void NotesAttachment(Stream input);

请提供有关该服务以及如何从客户端调用它的示例。

在VS 2015上使用C＃4.5.1。

Answer 1

请参考我的示例
IServcie1.cs

[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
Task UploadStream(Stream stream);

Service1.svc.cs

public async Task UploadStream(Stream stream)
        {
            using (stream)
            {
                using (var file = File.Create(Path.Combine(HostingEnvironment.MapPath("~/Uploads"), Guid.NewGuid().ToString() + ".png")))
                {
                    await stream.CopyToAsync(file);
                }
            }
        }

Web.config
