我关注了article将 WCF 服务包含到我的 ASP.NET 核心应用程序中。
查看 reference.cs 中的下一行,似乎默认端点配置是在 reference.cs 中硬编码的。
return new System.ServiceModel.EndpointAddress("http://localhost:49945/SimpleService.svc");
这就是我如何在 asp.net 核心 Controller 中创建我的客户端-
BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
EndpointAddress endpointAddress = new EndpointAddress("http://localhost:49945/SimpleService.svc");
wcfClient = new SimpleServiceClient(basicHttpBinding, endpointAddress);
所以我的问题是-
我应该在哪里维护端点详细信息,以便在部署期间可以轻松配置它?
如何从配置文件 (appsetting.json) 动态传递端点详细信息(地址和绑定(bind))?
生成的 Reference.cs 文件如下所示-

最佳答案
我过去需要同样的东西,最终在应用程序的选项中存储了 WCF 服务的连接详细信息。我将详细信息存储在 appsettings.json 文件中,创建了一个 Options 类,并将其注册到服务设置逻辑中,以便我可以在创建 WCF 服务时请求它。
使用我的代码,我很快就完成了。我没有测试它是否存在常见错误,例如缺少大括号、分号或拼写错误 :-P
选项类
public class MyServiceOptions
{
public string EndpointUrl {get;set;}
}
摘自 startup.cs
public void ConfigureServices(IServiceCollection services)
{
services.Configure<MyServiceOptions>Configuration.GetSection("MyService"));
//Other calls as needed...
}
appsettings.json
{
"MyService": {
"EndpointUrl": "http://localhost:49945/SimpleService.svc"
}
}
然后您可以通过请求 IOptions<MyServiceOptions>
的实例来访问您的选项以多种方式从依赖项注入(inject)容器。
public class MyController : Controller
{
//Option 1, in controller constructor
private IOptions<MyServiceOptions> myOptions;
public MyController(IOptions<MyServiceOptions> myOptions1)
{
myOptions = myOptions1
}
//Option 2, in action method signature
public IActionResult MyAction([FromServices]IOptions<MyServiceOptions> myOptions2)
{
//Option 3, directly
var myOptions3 = HttpContext.RequestServices.GetService<IControllerFactory>();
//NOTE: The GetService<>() method is an extension method from the Microsoft.Extensions.DependencyInjection namespace
BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
EndpointAddress endpointAddress = new EndpointAddress(myOptions.Value.EndpointUrl);
wcfClient = new SimpleServiceClient(basicHttpBinding, endpointAddress);
}
}
