我遇到 WCF 服务错误 ....Found 节点类型 'Element'名称为“tns:downloadOrders”

Question

我已经接管了一个使用 svc 文件在 asp.net c# 中制作的项目，该项目或多或少是完整的。我有第三方尝试连接到此服务。 他们在尝试运行 DownloadOrders 操作时收到错误

抱歉，如果这很愚蠢，但我不知道 SOAP Web 服务

OperationFormatter 遇到了无效的消息正文。期望找到名称为“DownloadOrders”和命名空间“http://schema.example.com”的节点类型“Element”。找到节点类型“Element”，名称为“tns:downloadOrders”，命名空间为“

”

namespace WebShopServiceLibrary
{
using System;
using System.Collections.Generic;
using System.ServiceModel;

[ServiceContract(Namespace = "http://schema.example.com", Name = "DownloadOrders")]
public interface IWebShopService
{
    [OperationContract]
    bool CompleteOrder(string cartId);
    [OperationContract(Action = "http://mywebsite.com/WebShopService?class=WebShopService&method=downloadOrders",
        Name = "DownloadOrders", ReplyAction = "http://schema.example.com")]

    IList<WSOrder> DownloadOrders();
    [OperationContract]
    string SayHello();
    }
}

http://schema.example.com 没有运气。

任何帮助将不胜感激

Answer 1

名称不匹配：

DownloadOrders

并

tns:downloadOrders

注意大小写的差异。您必须确保服务器和客户端匹配。
