在GET/POST方法中给出400错误请求的WCF方法

Question

当我尝试从浏览器中点击URL时，我新创建了一个WCF并且m面临400错误请求错误。

我的服务合同看起来像

[OperationContract] 
[WebInvoke(Method = "GET", UriTemplate = "GetUsers")] 
string GetUsers(); 

我已在webconfig的条目

<serviceMetadata httpGetEnabled="true"/> 

网址我打了浏览器

http://localhost:51561/AceWebService.svc/GetUsers 

这里是部分webconfig：

<system.serviceModel> 
    <services> 
     <service name="AceWebService.AceWebService" behaviorConfiguration="AceWebService.AceWebServiceBehavior"> 
      <!-- Service Endpoints --> 
      <endpoint address="" binding="wsHttpBinding" contract="AceWebService.IAceWebService"> 
       <!-- 
      Upon deployment, the following identity element should be removed or replaced to reflect the 
      identity under which the deployed service runs. If removed, WCF will infer an appropriate identity 
      automatically. 
     --> 
       <identity> 
        <dns value="localhost"/> 
       </identity> 
      </endpoint> 
      <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> 
     </service> 
    </services> 
    <behaviors> 
     <serviceBehaviors> 
      <behavior name="AceWebService.AceWebServiceBehavior"> 
       <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> 
       <serviceMetadata httpGetEnabled="true"/> 
       <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> 
       <serviceDebug includeExceptionDetailInFaults="true"/> 
      </behavior> 
     </serviceBehaviors> 
    </behaviors> 
</system.serviceModel> 

已经提到所有问题在这里* ..没有得到任何帮助..请建议的变化。

thnx

Answer 1

您已经使用在端点定义的的wsHttpBinding。只需将其更改为webHttpBinding，即可使其工作。

Answer 2

首先，使用WebGet进行GET请求。其次，在没有服务合同界面的情况下获得服务，然后在其工作时将合同移动到界面中。

这个工作对我来说：

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] 
[ServiceContract] 
public class HelloService 
{ 

    [WebGet(UriTemplate = "helloworld")] 
    [OperationContract] 
    public string HelloWorld() 
    { 
     return "Hello World!"; 
    } 

}
