一个已经写好的项目中有多个WebService,由于之前没有记录请求信息的,有时候需要查错等需要找到当次的请求信息,所以需要加入记录请求信息的功能。
首先想到的是在每一个带有WebMethod特性的方法里调用记录请求信息的方法,这样可以记录信息,但是太多带WebMethod特性的方法了,于是想在全局中拦截并捕获,于是想到了Global.asax
public class Global : System.Web.HttpApplication { protected void Application_Start(object sender, EventArgs e) { } protected void Session_Start(object sender, EventArgs e) { } protected void Application_BeginRequest(object sender, EventArgs e) { if (Request != null) { try { if (".asmx".Equals(Request.CurrentExecutionFilePathExtension,StringComparison.OrdinalIgnoreCase) && Request.ContentLength > 0) { using (MemoryStream ms = new MemoryStream()) { Request.InputStream.CopyTo(ms); ms.Position = 0; using (StreamReader reader = new StreamReader(ms)) { LogHelper.Info(reader.ReadToEnd()); } } } } catch (Exception) { } finally { Request.InputStream.Position = 0; } } } protected void Application_AuthenticateRequest(object sender, EventArgs e) { } protected void Application_Error(object sender, EventArgs e) { } protected void Session_End(object sender, EventArgs e) { } protected void Application_End(object sender, EventArgs e) { } }
