带有JSON，JSONP和SOAP端点的WCF服务 [英] WCF Services with JSON, JSONP and SOAP End Points

问题描述

我使用SOAP端点配置了传统的WCF服务.在我的客户项目中，我添加了服务参考"等.这些按预期方式工作.

I configured traditional WCF Services using SOAP end points. In my client project I added the Service Reference, etc. These are working as expected.

我创建了一个启用JSONP的WCF服务，对.svc文件，Web配置等进行了修改.我创建了一个测试客户端页面进行测试.我已成功调用JSONP服务.

I created a JSONP enabled WCF Service, made the modifications to the .svc file, web config, etc. I created a test client page to test. I am successfully calling the JSONP Service.

但是，我对Web配置所做的更改破坏了SOAP服务的服务参考.我想同时使用两种类型的终点.我不确定如何配置服务和Web配置.

However, the changes I made to the web config broke the service reference for the SOAP services. I'd like to use both type of end points. I am not sure how to configure the services and web config.

如果仅获取http，则每个操作(无论是用于SOAP还是JSONP)都可以用[WebGet(ResponseFormat = WebMessageFormat.Json)]

If http get only, can every operation (regardless if it is intended for SOAP or JSONP) be decorated with: [WebGet(ResponseFormat = WebMessageFormat.Json)]

然后我的服务类别需要:[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

Then my Service Class needs: [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

当我现在尝试在客户项目中更新我的服务参考时，我会得到

When I now attempt to Update my Service Reference in my client project I am getting

一个绑定实例已经被关联来监听URI'http://flixsit:1000/FlixsitWebServices.svc'.如果两个端点要共享相同的ListenUri，则它们还必须共享相同的绑定对象实例.这两个冲突的端点是在AddServiceEndpoint()调用中，配置文件中指定的，或者是AddServiceEndpoint()和config的组合.

A binding instance has already been associated to listen URI 'http://flixsit:1000/FlixsitWebServices.svc'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config.

将SOAP配置添加到我的webconfig中也会破坏JSONP端点.在客户端调用JSONP不需要客户端服务引用(或代理生成)，但是SOAP确实需要吗?

Adding SOAP configuration to my webconfig also breaks the JSONP endpoint. Calling JSONP on the client side doesnt require client service reference (or proxy generation), but SOAP does, correct?

我的服务WebConfig:

My Service WebConfig:

推荐答案

该错误清楚地说明了问题所在.您有两个地址相同但绑定不同的端点.不允许.通过绑定webHttpBinding在端点中设置address ="jsonp".您将在/ Service .svc/jsonp

The error clearly describes the problem. You have two endpoits with the same address but different bindings. It is not allowed. Set address="jsonp" in the endpoint with binding webHttpBinding. You will call the endpoint on /Service.svc/jsonp
