我收到当我尝试从一个Web浏览器的WebHttpBinding服务 连接到我的WCF这个奇怪的错误：

  

Sendera：ActionNotSupportedThe消息动作''不能在接收器进行处理时，由于一个错配ContractFilter在EndpointDispatcher。这可能是因为一个合同不匹配或发送方和接收方之间的结合/安全不匹配（发送者和接收者之间不匹配的操作）。检查发送者和接收者有相同的合同，相同的绑定（包括安全要求，如信息，运输，无）。

我的app.config：

 ＆LT;服务＆GT;
  ＆LT;服务名称=MyNamespace.MyService＆GT;
    ＆LT;主机＆GT;
      ＆LT; baseAddresses＆GT;
        ＆LT;新增baseAddress =HTTP：//本地主机：9091 /为MyService //＆GT;
      ＆LT; / baseAddresses＆GT;
    ＆LT; /主机＆GT;
    ＆LT;端点地址=绑定=的WebHttpBinding合同=MyNamespace.IMyService/＆GT;
  ＆LT; /服务＆GT;
＆LT; /服务＆GT;
 

我的方法只是看起来是这样的：

  [WebGet（UriTemplate =富/ {ID}）]
公共字符串的getFoo（串号）
{...
 

解决方案

确定 - 我希望你可能缺少必要的终结点行为 - 尝试此配置：

 ＆LT;行为＆GT;
  ＆LT; endpointBehaviors＆GT;
    ＆LT;行为NAME =网络＆GT;
      ＆LT; webHttp /＆GT;
    ＆LT; /行为＆GT;
  ＆LT; / endpointBehaviors＆GT;
＆LT; /行为＆GT;
＆LT;服务＆GT;
  ＆LT;服务名称=MyNamespace.MyService＆GT;
    ＆LT;主机＆GT;
      ＆LT; baseAddresses＆GT;
        ＆LT;新增baseAddress =HTTP：//本地主机：9091 /为MyService //＆GT;
      ＆LT; / baseAddresses＆GT;
    ＆LT; /主机＆GT;
    ＆LT;端点
        地址=
        behaviorConfiguration =网
        绑定=的WebHttpBinding
        合同=MyNamespace.IMyService/＆GT;
  ＆LT; /服务＆GT;
＆LT; /服务＆GT;
 

I'm getting this strange error when I try connect to my WCF with webHttpBinding service from a web browser:

Sendera:ActionNotSupportedThe message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).

My app.config:

<services>
  <service name="MyNamespace.MyService">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:9091/MyService/" />
      </baseAddresses>
    </host>
    <endpoint address="" binding="webHttpBinding" contract="MyNamespace.IMyService" />
  </service>
</services>

My method simply looks like this:

[WebGet(UriTemplate = "foo/{id}")]
public string GetFoo(string id)
{ ...

解决方案

OK - I would expect you're probably missing the endpoint behavior needed - try this config:

<behaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp/>
    </behavior>
  </endpointBehaviors>
</behaviors>    
<services>
  <service name="MyNamespace.MyService">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:9091/MyService/" />
      </baseAddresses>
    </host>
    <endpoint 
        address="" 
        behaviorConfiguration="web"
        binding="webHttpBinding" 
        contract="MyNamespace.IMyService" />
  </service>
</services>
