自托管WCF REST服务JSON POST方法不允许

标签: javascript c# jquery json wcf

到目前为止,我已经在互联网上看到了成千上万的这些“WCF”问题,但我开始认为这是不可能的。请有人告诉我,我错了......

背景:我正在使用自托管WCF服务(因此Global.asax.cs在这里没有帮助)。此外,端点也以编程方式定义。合同用WebInvoke(Method =“POST”)修饰,我正在对服务进行JQuery调用。

预检最初使用OPTIONS方法,但POST方法失败,405方法不允许。 GET功能也可以很好地工作。

我一直在网上搜索并试验了大约一个月,它不会让步。这个服务已经对通过TCP调用它的另一个客户端做出了很好的响应......请一些天才可以帮助我。感谢

PS:我认为POST响应真的很奇怪,就是允许:OPTIONS ......当然不应该存在吗?

CORS

    public class CORSEnablingBehavior : BehaviorExtensionElement, IEndpointBehavior
    {
    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher)
    {
        var requiredHeaders = new Dictionary<string, string>();

        requiredHeaders.Add("Access-Control-Allow-Origin", "*");
        requiredHeaders.Add("Access-Control-Allow-Methods", "POST, GET, PUT, DELETE, OPTIONS");
        requiredHeaders.Add("Access-Control-Allow-Headers", "Origin, Cache-Control, Connection, Pragma, Content-Length, Content-Type, Accept, Accept-Encoding, Accept-Language, Host, User-Agent");

        endpointDispatcher.DispatchRuntime.MessageInspectors.Add(new CORSHeaderInjectingMessageInspector(requiredHeaders));
    }

的app.config

  <system.serviceModel>
<behaviors>
  <endpointBehaviors>
    <behavior name="SOAPDemoEndpointBehavior">
    </behavior>
    <behavior>
      <webHttp/>
      <crossOriginResourceSharingBehavior/>
    </behavior>
  </endpointBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<extensions>
  <behaviorExtensions>
    <add name="crossOriginResourceSharingBehavior" type="Application.Host.CORSEnablingBehavior, Application.Host, Version=1.0.0.0, Culture=neutral"/>
  </behaviorExtensions>
</extensions>
<bindings>
  <basicHttpBinding>
    <binding name="OrdersMappingSoap"/>
  </basicHttpBinding>

  <!--2015-08-26-->
  <webHttpBinding>
    <binding name="webHttpBindingWithJson"
          crossDomainScriptAccessEnabled="true" />
  </webHttpBinding>

接口

[OperationContract(Name = "Relational")] 
[FaultContract(typeof(ValidationFault))]
[WebInvoke(Method = "POST", UriTemplate = "GetCustomerRelational", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
CustomerFullModel GetCustomerRelational(int clientHandle, object customerID, bool loadRelationalData);

JQuery的

jQuery.ajax({
  crossDomain: true,
  type: "POST",
  contentType: "application/json",
  url: "http://localhost:8086/CustomerService/rest/GetCustomerRelational/",
  data: JSON.stringify({
    "clientHandle": 1824,
    "customerID": "ABB029",
    "loadRelationalData": true
  }),
  dataType: "json",
  success: function(result) {
    console.log("Success...");
    document.getElementById("lblResponse").innerHTML = "Success: " + JSON.stringify(result.NormalResult);
  },
  error: function(x, s, t) {
    console.log("Error...");
    document.getElementById("lblResponse").innerHTML = x.responseText;
  }
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
