错误404当调用宁静的WCF服务 [英] Error 404 When calling Restful Wcf Service

问题描述

我一次又一次地做了搜索，但我真的不知道我缺少什么。我有WCF方法调用的服务回报错误404后，资源无法找到。

这样的网址：本地主机：3522 / AccountService.svc / accountbalance / 1

我运行它从视觉与IIS 8防爆preSS。

这样的WCF方法

  [的ServiceContract]
公共接口IAccountService
{
    [OperationContract的]
    [WebGet（UriTemplate =accountbalance / {帐户ID}）]
    十进制GetAccountBalance（字符串帐户ID）;
}
 

这是我的web.config

 ＆LT;绑定＆GT;
  ＆LT; / basicHttpBinding的＆GT;
  ＆LT;的WebHttpBinding＆GT;
    ＆LT;绑定名称=的WebHttpBinding＆GT;
      ＆LT;安全模式=运输＆GT;

      ＆LT; /安全＆GT;
    ＆LT; /装订＆GT;
  ＆LT; /的WebHttpBinding＆GT;
＆LT; /绑定＆GT;

＆LT;服务＆GT;

＆LT; serviceHostingEnvironment aspNetCompatibilityEnabled =真multipleSiteBindingsEnabled =真/＆GT;
 

解决方案

我通过2种方式解决了这个问题：

1. 为传输安全模式， SSL 必须启用和服务必须在SSL被调用channed。
2. 为 TransportCredentialOnly 安全模式，REST式服务工作正常 HTTP 。

@adkSerenity：感谢您的SSL建议，并跟踪

最好的问候， 武

I did the search again and again but I don't really know what am I missing. I have WCF method and after calling, the service return with error 404, resource can not be found.

The url like this: localhost:3522/AccountService.svc/accountbalance/1

I run it from Visual with IIS 8 Express.

The WCF method like this

[ServiceContract]
public interface IAccountService
{
    [OperationContract]
    [WebGet(UriTemplate = "accountbalance/{accountId}")]
    decimal GetAccountBalance(string accountId);
}

And this is my web.config

<bindings>
  </basicHttpBinding>
  <webHttpBinding>
    <binding name="WebHttpBinding">
      <security mode="Transport">
        <transport clientCredentialType="Windows" proxyCredentialType="Windows" />
      </security>
    </binding>
  </webHttpBinding>
</bindings>

<services>
  <service behaviorConfiguration="ProfileServiceDefaultBehavior"
    name="MyWcfService.AccountService">
    <endpoint behaviorConfiguration="RestFulBehavior" binding="webHttpBinding"
      bindingConfiguration="WebHttpBinding" name="AccountServiceEndpoint"
      bindingName="AccountServiceBinding" contract="MyWcfService.IAccountService" />
    <endpoint address="mex" behaviorConfiguration="" binding="mexHttpBinding"
      contract="IMetadataExchange" />
  </service>
</services>

<behaviors>
  <endpointBehaviors>
    <behavior name="RestFulBehavior">
      <webHttp automaticFormatSelectionEnabled="true" />
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="ProfileServiceDefaultBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />

解决方案

I resolved the issue by 2 ways:

1. For Transport security mode, SSL must be enabled and the service must be call in SSL channed.
2. For TransportCredentialOnly security mode, the Restful service works fine with http.

@adkSerenity: thanks for the SSL suggestion, and tracing.
