Question

我按照这个示例制作了我的第一个WCF服务：WCF REST Service JSON，然后编辑它以创建我自己的服务。我能够使用ASP.NET Developer Server使我的服务在调试中运行良好。我打开端口8081（在服务器，防火墙和路由器上），然后将其分配到IIS中的“注册”文件夹。然后我花了一天的时间将服务发布到运行IIS 6的Windows Server 2003，我必须使用MsDeployAgentService。然后，我使用IIS将ASP.NET版本设置为4.0.3019。 Registration文件夹包含Service1.svc，Web.config和bin文件夹。

这是我的网络配置文件：

<?xml version="1.0"?>
<configuration>
  <configSections>
    </configSections>
  <connectionStrings>
    <add name="ServiceApp.Properties.Settings.RegistrationConnection"

                        maxStringContentLength="2147483647" />
        </binding>
      </webHttpBinding>
    </bindings>
    <services>
      <service name="ServiceApp.Service1" behaviorConfiguration="ServiceBehaviour">
        <endpoint address=""  binding="webHttpBinding" bindingConfiguration="StreamedRequestWebBinding" contract="ServiceApp.IService1" behaviorConfiguration="web">
        </endpoint>
          </service>
    </services>
    <behaviors>

        <behavior name="ServiceBehaviour">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
</configuration>

当我尝试使用测试客户端使用服务时，我会使用以下语句获得错误404

byte[] data = client.DownloadData("http://ServerIP:8081/Registration/Service1.svc/CheckSoftware/1/Customer1/1_0/abc123/1/1");

当我删除端口时，我收到错误401“未授权”

byte[] data = client.DownloadData("http://ServerIP/Registration/Service1.svc/CheckSoftware/1/Customer1/1_0/abc123/1/1");

我尝试过使用LAN IP以及WAN IP地址。

关注this post，因为它看起来很喜欢OP遵循相同的例子并且有simalar问题，但它没有帮助。

然后我查看了服务器上的事件查看器，并在我输入端口号时找到了这个：

WebHost failed to process a request.
 Sender Information: System.ServiceModel.Activation.HostedHttpRequestAsyncResult/23878916
 Exception: System.Web.HttpException (0x80004005): The service '/Registration/Service1.svc' does not exist. ---> System.ServiceModel.EndpointNotFoundException: The service '/Registration/Service1.svc' does not exist.

   at System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result)

我可以清楚地看到该文件夹中存在Service1.svc文件。我在这一点上很迷茫，并希望得到任何帮助。

您的UriTemplate设置正确吗？ 404错误表明它根本没有与服务/方法联系。

REST服务是简单的web apis，而不是像普通的WCF服务那样尝试导入服务，尝试正常的http请求（只是一个简单的例子，而不是解决方案）：

    //declare the request (not sure of your uri, so i guessed)
    var queryString = string.Format("1/{0}/1_0/{1}/1/1", Param1, Param2);
    var req = 
        HttpWebRequest)WebRequest.Create("http://ServerIP:8081/Registration/Service1.svc/CheckSoftware/"); //base address of service
    req.Method = "POST";
    req.ContentType = "application/x-www-form-urlencoded";

    //build the fields stream
    var fields = Encoding.UTF8.GetBytes(queryString);
    req.ContentLength = fields.Length;

    //put the request info into the stream
    var requestStream = req.GetRequestStream();
    requestStream.Write(fields, 0, fields.Length);
    requestStream.Close();

    //execute the request
    var resp = (HttpWebResponse)req.GetResponse();

    //pull your infos
    var statusCode = (int)resp.StatusCode;
    var body = new StreamReader(resp.GetResponseStream()).ReadToEnd();

Answer 2

将IIS 6.0用于服务时，我不需要在URL中包含文件夹名称。因此，只需更改一行代码即可解决我的问题。

byte[] data = client.DownloadData("http://ServerIP:8081/Service1.svc/CheckSoftware/1/Customer1/1_0/abc123/1/1");

WCF REST JSON服务返回错误404 /异常：System.Web.HttpException（0x80004005）
