如何使本地JSONP现有WCF服务？ [英] How to natively enable JSONP for existing WCF service?

问题描述

我有一个像下面的方法现有的服务：

I have a an existing service like the below method:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)]
public class SomeService : ISomething
{
    public SomeListResults SomeList(SomeParams someParams)
    {
          ....
    }
}

有没有一种简单的方法，让JSONP调用，也JSON在同一时间（检测到它）。这是原生？

Is there a simple way to allow JSONP calls and also JSON at the same time (detect it). Is this native?

推荐答案

更​​新你的配置看起来像：

Update your config to look like:

<configuration>
  <system.web>
    <compilation debug="true" targetframework="4.0">
    <authentication mode="None">
  </authentication></compilation></system.web>
  <system.webserver>
    <modules runallmanagedmodulesforallrequests="true">
  </modules></system.webserver>
  <system.servicemodel>
    <servicehostingenvironment **aspnetcompatibilityenabled**="true">
    <standardendpoints>
      <webscriptendpoint>
        <standardendpoint **crossdomainscriptaccessenabled**="true" name="">
      </standardendpoint></webscriptendpoint>
    </standardendpoints>
  </servicehostingenvironment></system.servicemodel>
</configuration>

在这里看到一篇博客文章提供创建WCF服务，这是访问的跨域的演练。

See here for a blog post providing a walkthrough of creating a wcf service that's accessible cross-domain.

这将使你的服务接受跨域资源的请求。

This will enable your service to accept requests from cross-domain sources.

在确定条款是否垫你的回应（在JSONP的P）

In terms of determining whether to pad your response (the p in jsonp),

由于@carlosfigueira此：

Thanks to @carlosfigueira for this:

如果使用.NET 4中JSONP是原生支持。只要请求有所谓的回调（这个名字可配置）查询字符串参数，响应将与函数名称进行填充
  。

If using .Net 4 JSONP is supported natively. As long as the request has a query string parameter called "callback" (this name can be configured), the response will be padded with the function name .

否则，你需要编写适当垫响应的自定义消息检查。

Otherwise, you'll need to write a custom message inspector that pads the response appropriately.
