找不到WCF REST服务返回方法

Question

我已经开发了WCF REST服务，并尝试使用Asp.net进行测试，尽管可以与wcf测试客户端一起使用。 非点网客户端可能会使用此服务。

我正在尝试在asp.net中创建一个测试页以通过邮寄验证此服务。 当前，此服务托管在我的IIS中

在使用中：

[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json,
           BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "/MySVC?stringP={stringP}")]
        Stream MySVC(string stringP); 

在asp.net

$.ajax({
            type: "POST", //GET or POST or PUT or DELETE verb
            url: "http://localhost/MySvcHost/MySVC.svc?stringP",
            cache: false,
            data: '[{stringP:"samplestring"}]',
            dataType: "jsonp",
            processData: true,
            success: function (msg) {
            },
            error: function (err) {
            }
        })

当我运行测试应用程序时，它转到错误块，并且Fiddler显示错误“不允许使用方法”并显示为GET。 我还看到其他参数（callback =）如果将“ jsonp”更改为“ json”，则会引发“传输错误”

我该怎么办？

更新： service web.config

编辑3：

1. 将baseAddress添加到您的web.config中，并删除所有不必要的内容：

    <system.serviceModel> <services> <service name="Service.ParseService" behaviorConfiguration="ServiceBehaviour" > <endpoint address="" binding="webHttpBinding" behaviorConfiguration="webBehavior" contract="Service.RestServiceInterface" name="BasicHttpBinding_RestServiceInterface2"> </endpoint> <host> <baseAddresses> <add baseAddress="http://localhost:14502/MySvcHost/MySVC.svc"/> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior name="ServiceBehaviour"> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="webBehavior"> <webHttp /> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> 

2. 启用CORS，在服务项目的以下行中添加到web.config：

    <system.webServer> <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> <add name="Access-Control-Allow-Methods" value="GET, POST" /> </customHeaders> </httpProtocol> </system.webServer> 

3. 您的项目中必须有MySVC.svc。 内容应如下所示：

    <%@ ServiceHost Language="C#" Factory="System.Data.Services.DataServiceHostFactory, System.Data.Services, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" Service="Service.ParseService" %> 

4. 接口应为：

    [ServiceContract] public interface RestServiceInterface { [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "MySVC")] Stream MySVC(string stringP); } 

   *请注意，接口名称应从I开始-IFileService，IMessageService ...
   * Uri应该标识资源并应具有如下描述性：

    POST: http://localhost/files/ GET: http://localhost/files/1

5. 方法实现示例：

    public Stream MySVC(string stringP) { var mem = new MemoryStream(); var ser = new DataContractJsonSerializer(typeof(string)); ser.WriteObject(mem, stringP); mem.Seek(0, SeekOrigin.Begin); return mem; } 

6. Ajax呼叫：

    $.ajax( { type: "POST", processData: false, contentType: "application/json", url: "http://localhost:14502/MySvcHost/MySVC.svc/MySVC", data: '"plnainString"', dataType: "jsonp", success: function (data) { alert(data); }, error: function (data) { alert('error')); } }) 

   *注意：如果您从不同的计算机上调用该服务，则该服务已托管，您必须将localhost更改为具体的计算机名称（或IP）

7. 仅用于调试目的，包括对故障消息的异常堆栈跟踪。 更改服务项目上的web.config（includeExceptionDetailInFaults =“ true”）：

    <serviceBehaviors> <behavior name="ServiceBehaviour"> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors>
