WCF 服务返回“不允许的方法" [英] WCF Service Returning "Method Not Allowed"

问题描述

在开发我的第一个 WCF 服务的过程中，当我尝试使用它时，我得到Method not Allowed"，没有其他解释.

In the process of developing my first WCF service and when I try to use it I get "Method not Allowed" with no other explanation.

我已经使用 ServiceContract 和 OperationContract 设置了我的接口:

I've got my interface set up with the ServiceContract and OperationContract:

    [OperationContract]
    void FileUpload(UploadedFile file);

连同实际方法:

    public void FileUpload(UploadedFile file) {};

要访问服务，我输入 http://localhost/project/myService.svc/FileUpload但我收到不允许的方法"错误

To access the Service I enter http://localhost/project/myService.svc/FileUpload but I get the "Method not Allowed" error

我错过了什么吗?

推荐答案

您的浏览器正在发送 HTTP GET 请求:确保您在合同中的操作上具有 WebGet 属性:

Your browser is sending an HTTP GET request: Make sure you have the WebGet attribute on the operation in the contract:

[ServiceContract]
public interface IUploadService
{
    [WebGet()]
    [OperationContract]
    string TestGetMethod(); // This method takes no arguments, returns a string. Perfect for testing quickly with a browser.

    [OperationContract]
    void UploadFile(UploadedFile file); // This probably involves an HTTP POST request. Not so easy for a quick browser test.
 }
