Question

我有以下WCF网络服务：

我在IService1中定义

    [OperationContract]
    [WebInvoke(Method = "POST")]
    string testSer();

和In Service1.svc

public string testSer()
{
return "test";
}

我从C＃winForm应用程序调用Web服务，如下所示：

var client = new RestClient("http://localhost/webservices/Service1.svc/");


            var request = new RestRequest("testSer", Method.POST);
            IRestResponse response = client.Execute(request);
            var content = response.Content; // raw content as string
            MessageBox.Show(content);

返回的响应是“Method Not Allowed”。如果我将方法类型更改为“GET”，则可以正常工作。

如果我尝试从浏览器调用“POST”方法，则返回的响应是“Method Not Allowed”

我的配置文件：

修改当我尝试使用WCF测试客户端（微软Visual Studio附带）测试服务时，我收到以下错误：

Answer 1

像下面的代码一样更改webconfig

<system.webServer>
<handlers>
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <remove name="OPTIONSVerbHandler" />
  <remove name="TRACEVerbHandler" />
  <remove name="WebDAV" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
<modules>
<remove name="WebDAVModule" />
</modules>
 <security>
    <requestFiltering>
        <verbs allowUnlisted="false">
            <add verb="GET" allowed="true" />
            <add verb="POST" allowed="true" />
            <add verb="DELETE" allowed="true" />
            <add verb="PUT" allowed="true" />
        </verbs>
    </requestFiltering>
  </security>
</system.webServer>

用

装饰你的营业合约

[OperationContract]
[WebInvoke(Method = "POST")]

在您的Web Config中应该是这样的：

   <system.serviceModel>
    <client />
    <behaviors>
      <endpointBehaviors>
        <behavior name="restfulBehavior">
          <webHttp defaultOutgoingResponseFormat="Json" defaultBodyStyle="Wrapped" automaticFormatSelectionEnabled="False" />
          <!--<enableWebScript />-->
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <basicHttpBinding>
        <binding name="soapService" />
      </basicHttpBinding>
      <webHttpBinding>
        <binding name="jsonp" crossDomainScriptAccessEnabled="true" />
      </webHttpBinding>
    </bindings>
    <protocolMapping>
      <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="false" multipleSiteBindingsEnabled="true" />
    <services>
      <service name="WcfService3.Service1">
        <endpoint address="" behaviorConfiguration="restfulBehavior" binding="webHttpBinding" bindingConfiguration="jsonp" name="jsonService" contract="WcfService3.IService1" />
        <endpoint address="mex" binding="mexHttpBinding" name="metadata" contract="IMetadataExchange" />
      </service>
    </services> 
  </system.serviceModel>

这是从后端点返回的数据：

首先感谢大家，特别感谢@ jalison-evora的帮助。

错误是由于NGinX配置造成的。
