跨域ajax和WCF [英] Cross domain ajax and WCF

问题描述

WCF 是否允许跨域 ajax 功能?

Is WCF allowing cross-domain ajax functionality?

我在 C# 中有一个 WCF 项目 (localhost:53763) 和一个 Web 应用程序 (localhost:50238).我试图在我的 Web 应用程序 ajax 调用中访问 WCF.我在控制台中遇到错误

I have a WCF project (localhost:53763) and a web application (localhost:50238) in C#. I tried to access WCF in my web application ajax call. I got error in console that

OPTIONS localhost:53763/WCFTest.svc/xml/1122 405(不允许的方法)jquery-1.9.1.min.js:5XMLHttpRequest 无法加载 localhost:53763/WCFTest.svc/xml/1122.Access-Control-Allow-Origin 不允许 Origin localhost:50238.

OPTIONS localhost:53763/WCFTest.svc/xml/1122 405 (Method Not Allowed) jquery-1.9.1.min.js:5 XMLHttpRequest cannot load localhost:53763/WCFTest.svc/xml/1122. Origin localhost:50238 is not allowed by Access-Control-Allow-Origin.

然后我通过在 IIS 中添加 WCF 项目来尝试它.然后我也得到了与上面相同的错误

Then I tried it by added the WCF project in IIS. Then also I got error same as above

选项 http://www.WCFTest.com/WCFTest.svc/xml/111 405(不允许的方法)jquery-1.9.1.min.js:5XMLHttpRequest 无法加载 http://www.WCFTest.com/WCFTest.svc/xml/111.Access-Control-Allow-Origin 不允许 Origin localhost:50238.

OPTIONS http://www.WCFTest.com/WCFTest.svc/xml/111 405 (Method Not Allowed) jquery-1.9.1.min.js:5 XMLHttpRequest cannot load http://www.WCFTest.com/WCFTest.svc/xml/111. Origin localhost:50238 is not allowed by Access-Control-Allow-Origin.

推荐答案

你需要在你的函数中实现这一行:

You need to implement this line to your functions:

WebOperationContext.Current.OutgoingResponse.Headers.Add("Access-Control-Allow-Origin", "*");

有几个选项可以装饰每个请求，但我找不到正确的界面.

There are several options to decorate every request, but I cannot find the correct interface for that.
