Question

我试图将endpoint和wshttpbinding配置移动到c＃文件，以便我可以在运行时更改端点地址（从下拉列表中选择，处理等）。但是在创建WsHttpBinding对象EndpointAddress对象并将它们传递给我的客户端之后。它将抛出以下异常：

System.ServiceModel.FaultException：调用者未经过身份验证通过服务

如果用户凭据不正确，这是我得到的相同异常。但是，他们还没有从使用Web.config文件更改为以编程方式创建这些配置选项。

Web.config（正常）：

<binding name="myService" maxReceivedMessageSize="2147483647">
    <readerQuotas
        maxDepth="2147483647"
        maxStringContentLength="2147483647"
        maxArrayLength="2147483647"
        maxBytesPerRead="2147483647"
        maxNameTableCharCount="2147483647" />

    <security mode="TransportWithMessageCredential">
        <transport clientCredentialType="None" />
        <message clientCredentialType="UserName" establishSecurityContext="false" />
    </security>
</binding>


<client>
    <endpoint
        address="https://address/myservice.svc"
        binding="wsHttpBinding"
        bindingConfiguration="myService"
        contract="MyService.IMyService"
        name="myService"
    />
</client>

MyService service = new MyService();
service.username = "user";
service.password = "pass";
//Success

以编程方式（不起作用）：

WSHttpBinding wsHttp = new WSHttpBinding();
wsHttp.MaxReceivedMessageSize = 2147483647;
wsHttp.ReaderQuotas.MaxDepth = 2147483647;
wsHttp.ReaderQuotas.MaxStringContentLength = 2147483647;
wsHttp.ReaderQuotas.MaxArrayLength = 2147483647;
wsHttp.ReaderQuotas.MaxBytesPerRead = 2147483647;
wsHttp.ReaderQuotas.MaxNameTableCharCount = 2147483647;
wsHttp.Security.Mode = SecurityMode.TransportWithMessageCredential;
wsHttp.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
wsHttp.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
wsHttp.Security.Message.EstablishSecurityContext = false;

EndpointAddress endpoint = new EndpointAddress("https://address/myservice.svc");

MyService service = new MyService(wsHttp, endpoint);
service.username = "user";
service.password = "pass";
//System.ServiceModel.FaultException: The caller was not authenticated by the service

我已经尝试过教程/寻找答案，但我无法弄清楚。

我的解决方案

保持绑定相同。

更改端点，使其没有地址

<client>
  <endpoint
    binding="wsHttpBinding" bindingConfiguration="myService"
    contract="MyService.IMyService" name="myService" />
</client>

通过更改Uri对象在运行时更改端点，并将端点名称作为第一个参数传递给您的服务

Uri uri = new Uri("https://address/myservice.svc");
var address = new EndpointAddress(uri);
service= new MyService("myService", address);
service.username = "user";
service.password = "pass";

您可以在app.config中删除所有内容-这样就没有绑定或接口信息。

您的运行时代码是这样的：

//create an endpoint address
var address = new EndpointAddress("http://localhost:51353/EmployeeService.svc");

//create a WSHttpBinding
WSHttpBinding binding = new WSHttpBinding();

//create a channel factory from the Interface with binding and address
var channelFactory = new ChannelFactory<IEmployeeService>(binding, address);

//create a channel
IEmployeeService channel = channelFactory.CreateChannel();

//Call the service method on the channel
DataSet dataSet = channel.SelectEmployees();

仅供参考，这是我的app.config：

<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
    </startup> 
</configuration>

/ ************您可以将其简化为：************************** ****** /

var factory = new ChannelFactory<IEmployeeService>(new WSHttpBinding());
var channel = factory.CreateChannel(new EndpointAddress("http://localhost:51353/EmployeeService.svc"));

端点和WSHttpBinding以编程方式
