如何自动记录.NET Core WebAPI中的每个请求? [英] How to auto log every request in .NET Core WebAPI?
问题描述
我希望每个请求都自动记录下来.在以前的.Net Framwork WebAPI项目中,我曾经注册过一个委托处理程序.
I'd like to have every request logged automatically. In previous .Net Framwork WebAPI project, I used to register a delegateHandler to do so.
WebApiConfig.cs
WebApiConfig.cs
public static void Register(HttpConfiguration config)
{
config.MessageHandlers.Add(new AutoLogDelegateHandler());
}
AutoLogDelegateHandler.cs
AutoLogDelegateHandler.cs
public class AutoLogDelegateHandler : DelegatingHandler
{
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
var requestBody = request.Content.ReadAsStringAsync().Result;
return await base.SendAsync(request, cancellationToken)
.ContinueWith(task =>
{
HttpResponseMessage response = task.Result;
//Log use log4net
_LogHandle(request, requestBody, response);
return response;
});
}
}
日志内容示例:
------------------------------------------------------
2017-08-02 19:34:58,840
uri: /emp/register
body: {
"timeStamp": 1481013427,
"id": "0322654451",
"type": "t3",
"remark": "system auto reg"
}
response: {"msg":"c556f652fc52f94af081a130dc627433","success":"true"}
------------------------------------------------------
但是在.NET Core WebAPI项目中,没有WebApiConfig
或Global.asax GlobalConfiguration.Configure(WebApiConfig.Register);
But in .NET Core WebAPI project, there is no WebApiConfig
, or the register function at Global.asax GlobalConfiguration.Configure(WebApiConfig.Register);
那么,在.NET Core WebAPI中有什么方法可以实现?
So is there any way to achieve that in .NET Core WebAPI?
推荐答案
您可以创建自己的过滤器属性...
You can create your own filter attribute...
public class InterceptionAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(HttpActionContext actionContext)
{
var x = "This is my custom line of code I need executed before any of the controller actions, for example log stuff";
base.OnActionExecuting(actionContext);
}
}
...,您将在GlobalFilters中注册它,但是由于您说的是使用.NET Core,因此可以尝试继续...
... and you would register it with GlobalFilters, but since you said you're using .NET Core, this is how you can try proceeding...
来自 docs.microsoft.com :
您可以全局注册过滤器(适用于所有控制器和操作) 通过将其添加到MvcOptions.Filters集合中 Startup类中的ConfigureServices方法:
You can register a filter globally (for all controllers and actions) by adding it to the MvcOptions.Filters collection in the ConfigureServices method in the Startup class:
让我们知道它是否有效.
Let us know if it worked.
