WCF服务 - 绝对基础 - 帮助？ [英] WCF Service - the absolute basics - help?

问题描述

我已经在这2天了，开始感到沮丧。我想创建一个简单的"hello world"。我可以"获取"的WCF服务使用jQuery。无论我做什么，我总是最终得到400 Bad Request。我已经搜索过MSDN文档，VS2008帮助，尝试了很多教程，然后是来自Rick Strahl等各种博主的代码，最近这篇文章http://www.dennydotnet.com/post/2008/03/03/Passing-a- JSON-object-to-a-WCF-service-with-jQuery.aspx。

我可以在端点http：//localhost/WCFService2/Service.svc浏览我的服务，它生成服务带文字的屏幕：

您已经创建了一项服务。

要
测试此服务，您需要创建一个客户端并使用它来调用
服务...

但是，我是不打算编写.NET客户端来使用该服务。相反，我将直接从Ajax请求调用服务。我用[WebInvoke（Method =" GET"）]]修饰了方法，并将服务配置为允许AspNetCompatibility。我的理解是，我应该能够浏览到http：//localhost/WCFService2/Service.svc/GetData并返回一些xml。当我尝试这一切时，我得到的是400 Bad Request。

我在这里缺少什么？我可以发布代码，但我的最新版本是来自VisualStudio 2008的WCFService模板，修改了GetData方法以返回包含"hello world"的字符串。

干杯，

T

解决方案

我设法取得了一些进展。我已经创建了一个简单的.svc文件：

< ％@ ServiceHost

语言 = " C＃"

Debug = " true"

服务 = " adbeast.JobProcessor.MonitorService"

工厂 = " System.ServiceModel.Activation.WebScriptServiceHostFactory"

％< font style ="color：blue">>

Hi, I've been at this for 2 days and starting to get frustrated.  I want to create a simple "hello world" WCF service that I can "GET" using jQuery.  No matter what I do I always end up with 400 Bad Request.  I have scoured MSDN documentation, VS2008 help, tried numerous tutorials, followed along with code from various bloggers like Rick Strahl and most recently this post http://www.dennydotnet.com/post/2008/03/03/Passing-a-JSON-object-to-a-WCF-service-with-jQuery.aspx.

I am able to browse to my service at the endpoint http://localhost/WCFService2/Service.svc which produces the Service screen with the text:

You have created a service.

To test this service, you will need to create a client and use it to call the service...

However, I am not going to be writing a .NET client to consume the service.  Instead I will be calling the service directly from an Ajax request.  I have decorated the method with [WebInvoke(Method = "GET")] and configured the service to allow AspNetCompatibility.  My understanding is that I should then be able to browse to http://localhost/WCFService2/Service.svc/GetData and return some xml.  When I try this all I get is 400 Bad Request.

What am I missing here?  I can post code, but my latest incarnation is the WCFService template from VisualStudio 2008 with the GetData method modified to return a string containing "hello world".

Cheers,

T

解决方案

I've managed to make some headway.  I've created a simple .svc file like so:

<%@ ServiceHost

Language="C#"

Debug="true"

Service="adbeast.JobProcessor.MonitorService"

Factory="System.ServiceModel.Activation.WebScriptServiceHostFactory"

%>
