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

Question

我跟着这个例子，使我的第一个WCF服务：WCF REST Service JSON，然后编辑它来创建我自己的。我能够让我的服务在使用ASP.NET Developer Server进行调试时运行良好。我打开了端口8081（在服务器，防火墙和路由器上），然后将其分配给IIS中的“注册”文件夹。然后，我花了一天的时间找出我必须使用MsDeployAgentService后，将服务发布到运行IIS 6的Windows Server 2003。然后我使用IIS将ASP.NET版本设置为4.0.3019。注册文件夹包含Service1.svc，Web.config和bin文件夹。

这是我的网络配置文件：

<?xml version="1.0"?>

    <configSections> 
    </configSections> 
    <connectionStrings> 
    <add name="ServiceApp.Properties.Settings.RegistrationConnection"

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

当我尝试使用了测试客户端的服务，我得到错误404用下面的语句

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

当我删除端口I得到一个错误401“未经授权”

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

我已经尝试使用LAN IP和WA N IP地址。

跟随this post，因为它看起来很喜欢OP遵循相同的例子，并有西米拉问题，但它没有帮助。

我然后看着在事件查看器在服务器上，发现这个时候我包含在端口号：

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.

Process ID: 3460 

我可以清楚地看到Service1.svc文件存在文件夹中。我很迷茫，并希望得到任何帮助。

编辑，包括更多的代码：

Answer 1

当使用IIS 6.0作为服务我不需要在URL中包含文件夹名称。所以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");

是您的UriTemplate设置是否正确？ 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的API，而不是试图导入服务，就像您正常的WCF服务，尝试一个普通的HTTP请求（只是一个光秃秃的例子，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();
