获取WebService的请求信息

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)
        {

        }
    }
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";
    }
}
View Code

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"));
        }
    }
View Code
