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) { } }logs_code_collapse">View Code
[WebMethod]
public string HelloWorld()
{
return "Hello World";
}
[WebMethod]
public string QueryBalance(string username,string password)
{
if (username == "test" && password == "abcd")
{
return "1000000";
}
else
{
return "用户名或密码错误";
}
}

这里使用了Log4Net将请求信息记录起来
另一种调用方式是在另一个项目中添加了WerService的引用,
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
TestWebServiceSoapClient client = new TestWebServiceSoapClient();
Response.Write(client.QueryBalance("test","abcd"));
}
}
