[英]Client can't find endpoint element of WCF Inside Windows Service
I'm trying to put a WCF service inside a Windows Service. 我正在尝试将WCF服务放在Windows服务中。 I used svcutil to use the CalculatorService.cs and output.config.
我使用svcutil来使用CalculatorService.cs和output.config。 I put the contents of the output.config into the App.config and write a client, including the CalculatorService.cs into it.
我将output.config的内容放入App.config中,并编写一个包括CalculatorService.cs的客户端。 When it runs, I get the error, "Could not find default endpoint element that references contract 'IAnswerResult' in the ServiceModel client configuration section".
运行时,出现错误“在ServiceModel客户端配置部分中找不到引用合同'IAnswerResult'的默认端点元素”。 In my client, I've just copied what the wizard said to use:
在我的客户端中,我刚刚复制了向导说的用法:
protected void Page_Load(object sender, EventArgs e)
{
AnswerResultClient client = new AnswerResultClient(); // error here
client.QuestionAnswered("1", "2", "3");
}
In App.config of the client (generated) I have the following but it tells me that the contract "IAnswerResult" is invalid. 在客户端(已生成)的App.config中,我具有以下内容,但它告诉我合同“ IAnswerResult”无效。 I don't know why... it's what was generated by svcutil.
我不知道为什么...这是svcutil生成的。

Any direction greatly appreciated. 任何方向都非常感谢。 This is my first attempt and I'm lost!
这是我的第一次尝试,我迷路了!
EDIT: I changed the Windows service ServiceContract namespace to: 编辑:我将Windows服务ServiceContract命名空间更改为:
[ServiceContract(Namespace = "http://CADEEternaService")]
In the client CalculatorService class: 在客户端CalculatorService类中:
[System.ServiceModel.ServiceContractAttribute(Namespace= "http://CADEEternaService", ConfigurationName="IAnswerResult")]
public interface IAnswerResult
{
[System.ServiceModel.OperationContractAttribute(Action= "http://CADEEternaService/IAnswerResult/QuestionAnswered", ReplyAction= "http://CADEEternaService/IAnswerResult/QuestionAnsweredResponse")]
string QuestionAnswered(string person_int, string course_int, string lesson_int);
[System.ServiceModel.OperationContractAttribute(Action= "http://CADEEternaService/IAnswerResult/QuestionAnswered", ReplyAction= "http://CADEEternaService/IAnswerResult/QuestionAnsweredResponse")]
System.Threading.Tasks.Task<string> QuestionAnsweredAsync(string person_int, string course_int, string lesson_int);
}
In the client's app.config: 在客户端的app.config中:
<endpoint address="http://localhost:6255/CalculatorService" binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IAnswerResult" contract="CADEEternaService.IAnswerResult"
name="BasicHttpBinding_IAnswerResult" />
<endpoint address="net.tcp://localhost:6256/CalculatorService"
binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IAnswerResult"
contract="CADEEternaService.IAnswerResult" name="NetTcpBinding_IAnswerResult">
But it's still flagging "CADEEternaService.IAnswerResult" as an error and I'm also getting the original error, "Could not find default endpoint element that references contract 'IAnswerResult'"... however, I find it odd that it's barking at IAnswerResult and not CADEEternaService.IAnswerResult in the error message. 但是它仍然将“ CADEEternaService.IAnswerResult”标记为错误,并且我也得到了原始错误,“找不到引用合同'IAnswerResult'的默认端点元素” ...但是,我发现奇怪的是它在IAnswerResult吠叫而不是错误消息中的CADEEternaService.IAnswerResult。
In your client's config, the contract needs to be a fully qualified name, not just the interface name. 在客户端的配置中,合同需要是完全限定名称,而不仅仅是接口名称。
<endpoint address="http://localhost:6255/CalculatorService"
binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IAnswerResult"
contract="EternaService.IAnswerResult"
name="BasicHttpBinding_IAnswerResult" />
<endpoint address="net.tcp://localhost:6256/CalculatorService"
binding="netTcpBinding"
bindingConfiguration="NetTcpBinding_IAnswerResult"
contract="EternaService.IAnswerResult"
name="NetTcpBinding_IAnswerResult">
In other words, EternaServie.IAnswerResult
, not just IAnswerResult
. 换句话说,是
EternaServie.IAnswerResult
,而不仅仅是IAnswerResult
。
You need to add the namespace of your Service Reference generated, before the contract .... contract="xxxxxxx.IAnswerResult 您需要在合同之前添加生成的服务引用的名称空间...。 contract =“ xxxxxxx.IAnswerResult
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IAnswerResult" />
</basicHttpBinding>
<netTcpBinding>
<binding name="NetTcpBinding_IAnswerResult" />
</netTcpBinding>
</bindings>
<client>
<endpoint address="http://localhost:6255/CalculatorService" binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IAnswerResult" contract="**xxxxx.IAnswerResult**"
name="BasicHttpBinding_IAnswerResult" />
<endpoint address="net.tcp://localhost:6256/CalculatorService"
binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IAnswerResult"
contract="IAnswerResult" name="NetTcpBinding_IAnswerResult">
<identity>
<servicePrincipalName value="host/Server2012" />
</identity>
</endpoint>
