Web服务调用失败404 [英] Webservice call failed 404

问题描述

我有使用WCF服务的项目。我通过ajax和处理程序调用服务。本地它工作正常，当我在IIS8中托管它时，我收到Webservice调用失败404错误。



有人可以帮我这个...



这是webconfig中使用的绑定

 <   system.serviceModel  >  
 < ;  行为 >  
  <   endpointBehaviors  >  
 <  行为   名称  =  ServiceAspNetAjaxBehavior >  
 <   enableWebScript /  >  
 < span class =code-keyword><   / behavior  >  
 <  行为    name   =  AjaxCallAspNetAjaxBehavior >  
 <   enableWebScript /  >  
 <   / behavior  >  
 <  行为    name   =  AJAXCallsAspNetAjaxBehavior >  
 <   enableWebScript /  >  
 <   / behavior  >  
 <   / endpointBehaviors  >  
 <   / behavior  >  
 <   serviceHostingEnvironment     aspNetCompatibilityEnabled   =  true    multipleSiteBindingsEnabled   =  true  /  > ;  
 <  服务  >  
 <   service    名称  = 服务 >  
 <   endpoint    地址  =     behaviorConfiguration   =  ServiceAspNetAjaxBehavior    bindingConfiguration   =  webBinding     binding   = < span class =code-keyword> webHttpBinding    contract   = 服务  /  >  
 <   / service  >  
 <   service    名称  =  AjaxCall  >  
 <   endpoint    地址  =     behaviorConfiguration   =  AjaxCallAspNetAjaxBehavior    bindingConfiguration   =  webBinding    binding   =  webHttpBinding   合同  =  AjaxCall  /  >  
 <   / service  >  
 <   service     name   =  AJAXCalls >  
 <   endpoint     address   =     behaviorConfiguration   =  AJAXCallsAs pNetAjaxBehavior    bindingConfiguration   =  webBinding    binding   =  webHttpBinding   合同  =  AJAXCalls  /  >  
 <   / service  >  
 <   / services  >  
 <   bindings  >  
 <   webHttpBinding  >  
 <   binding     name   =  webBinding < span class =code-keyword>>  
 <   security     mode   = 无  /  >  
 <   / binding  >  
 <   / webHttpBindi ng  >  
 <   / bindings  >  
 <   / system.serviceModel  >  

解决方案

404 - 未找到的意思。 HTTP 404 [ ^ ]。你应该检查你正在调用的URL，我怀疑URL包含端口号。请更正您的网址，然后重试

我已在Windows功能下为 WCF服务启用了 Http Activation ，这对我有用。

感谢您的帮助...

I have project using WCF service. I am calling the service through ajax and handlers. Locally it is working fine, when I host it in IIS8 I am getting Webservice call failed 404 error.

Can anybody please help me on this...

Here is the binding used in webconfig

<system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="ServiceAspNetAjaxBehavior">
          <enableWebScript/>
        </behavior>
        <behavior name="AjaxCallAspNetAjaxBehavior">
          <enableWebScript/>
        </behavior>
        <behavior name="AJAXCallsAspNetAjaxBehavior">
          <enableWebScript/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
    <services>
      <service name="Service">
        <endpoint address="" behaviorConfiguration="ServiceAspNetAjaxBehavior" bindingConfiguration="webBinding" binding="webHttpBinding" contract="Service"/>
      </service>
      <service name="AjaxCall">
        <endpoint address="" behaviorConfiguration="AjaxCallAspNetAjaxBehavior" bindingConfiguration="webBinding" binding="webHttpBinding" contract="AjaxCall"/>
      </service>
      <service name="AJAXCalls">
        <endpoint address="" behaviorConfiguration="AJAXCallsAspNetAjaxBehavior" bindingConfiguration="webBinding" binding="webHttpBinding" contract="AJAXCalls"/>
      </service>
    </services>
    <bindings>
      <webHttpBinding>
        <binding name="webBinding">
          <security mode="None"/>
        </binding>
      </webHttpBinding>
    </bindings>
  </system.serviceModel>

解决方案

404 - means not found. HTTP 404[^]. You should check the URL you are invoking, I suspecting the URL contains port number. Please correct your URL and try again

I have enabled the Http Activation for WCF service under Windows feature, and it worked for me.
