来自 .net WCF 服务的 405 响应错误

【中文标题】来自 .net WCF 服务的 405 响应错误【英文标题】:405 response error from .net WCF Service 【发布时间】:2012-12-09 09:44:53 【问题描述】:我正在尝试在 asp.net 中为我的应用程序编写后端,但在来自 Ext 的 Ajax 请求后,我的 WCF 服务无法返回 POST 响应。相反,我收到 405 'Method not allowed' 错误。
这是我的要求:
Ext.Ajax.request(
type: 'POST',
url: 'http://localhost:35798/RestServiceImpl.svc/export',
params:
html : 'array': document.body.innerHTML
,
success : function(response)
console.log('RESPONSE !', response);
//me.onSuccess(response, callback, errback);
,
failure : function(response)
console.log('RESPONSE FAIL !', response);
);
这是我的界面:
namespace RestService
public class RestServiceImpl : IRestServiceImpl
#region IRestServiceImpl Members
public string JSONData()
return "Your POST request";
#endregion
和服务代码:
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Web.Script.Services;
namespace RestService
[ServiceContract]
public interface IRestServiceImpl
[OperationContract]
[ScriptMethod]
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Bare,
UriTemplate = "export")]
string JSONData();
最后是配置:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service name="RestService.RestServiceImpl" behaviorConfiguration="ServiceBehaviour">
<!-- Service Endpoints -->
<!-- Unless fully qualified, address is relative to base address supplied above -->
<endpoint address ="" binding="webHttpBinding" contract="RestService.IRestServiceImpl" behaviorConfiguration="web">
<!--
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.
-->
</endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehaviour">
<!-- 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="false"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="web">

<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
【问题讨论】:
第一个猜测:我想说你需要去掉 ajax 请求中的“参数”,因为该方法不需要任何参数。 【参考方案1】:这可能是一个跨域问题。例如,如果您的服务位于 http://localhost:35798
并且发出 AJAX 请求的网页位于 http://localhost:80
,则浏览器仍将其视为 不同 域(即使只有端口号不同)。在这种情况下,某些浏览器发出 CORS 请求,如果您的服务不处理它,将返回 405。您的选择是(1)避免跨域请求,(2)实施 CORS(不会帮助浏览器不支持它),或(3)使用 JSONP。
