WCF - 从另一个 Web 应用程序（WCF 或 REST API）调用时出现 EndpointNotFoundException

Question

最近我在 WCF 中从另一个 Web 应用程序（WCF 或 REST API）调用时遇到了 EndpointNotFoundException 的问题。

我正在尝试连接到需要登录名和密码识别的外部 WCF 服务（现在我正在处理提供商准备的测试环境）。

然后异常发生：

There was no endpoint listening at https://xxx/yyy.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details

此问题不会出现在控制台应用程序中 - 运行顺畅，但仅在我创建简单项目（如 WCF 或 REST API）时才会出现。

TerytWs1Client tc = new TerytWs1Client();
tc.ClientCredentials.UserName.UserName = "TestPubliczny";
tc.ClientCredentials.UserName.Password = "1234abcd";
var zalogowany = tc.CzyZalogowany();

我也试过了：

try { 
var proxy = new ChannelFactory<TerytWsTest.ITerytWs1>("custom");
proxy.Credentials.UserName.UserName = "TestPubliczny";
proxy.Credentials.UserName.Password = "1234abcd";
var result = proxy.CreateChannel();
var test = result.CzyZalogowany();
} 
catch (Exception ex) { }

首先你要确保你的WCF服务已经启动，你可以通过浏览器查看WCF服务是否已经启动：

然后就可以通过添加服务引用来调用WCF服务了：

点击确定后会自动生成代理类，我们可以通过代理类调用WCF服务：
