如何计算HttpWebRequest花费的出站和入站互联网流量 [英] How to calculate HttpWebRequest spent outbound and inbound internet traffic

问题描述

我具有以下获取页面的功能.我的问题是我想计算花费了多少互联网连接

入站(下载)和出站流量(已发送)

我该怎么做?谢谢

我的功能

 public static string func_fetch_Page(string srUrl, int irTimeOut = 60,
    string srRequestUserAgent = "Mozilla/5.0 (Windows NT 6.3; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0",
    string srProxy = null)
    {
        string srBody = "";
        string srResult = "";
        try
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(srUrl);

            request.Timeout = irTimeOut * 1000;
            request.UserAgent = srRequestUserAgent;
            request.KeepAlive = true;
            request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

            WebHeaderCollection myWebHeaderCollection = request.Headers;
            myWebHeaderCollection.Add("Accept-Language", "en-gb,en;q=0.5");
            myWebHeaderCollection.Add("Accept-Encoding", "gzip, deflate");

            request.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip;

            using (WebResponse response = request.GetResponse())
            {
                using (Stream strumien = response.GetResponseStream())
                {
                    using (StreamReader sr = new StreamReader(strumien))
                    {
                        srBody = sr.ReadToEnd();
                        srResult = "success";
                    }
                }
            }
        }
        catch ()
        {

        }

@Simon Mourier我如何计算花费的流量

public static long long_GlobalDownload_KByte = 0;
public static long long_GlobalSent_KByte = 0;

Time  _timer_fetch_download_upload = new Timer(getDownload_Upload_Values, null, 0, 100 * 1000);

public static void getDownload_Upload_Values(Object state)
{
    using (Process p = Process.GetCurrentProcess())
    {
        foreach (var cnx in TcpConnection.GetAll().Where(c => c.ProcessId == p.Id))
        {
            Interlocked.Add(ref long_GlobalDownload_KByte, Convert.ToInt64(cnx.DataBytesIn));
            Interlocked.Add(ref long_GlobalSent_KByte, Convert.ToInt64(cnx.DataBytesOut));
        }
    }
}

解决方案

您可以使用 FiddlerCore (仅一个dll即可引用)，并为您的HttpWebRequest设置 WebProxy 来计算发送和接收的字节

public class WebConnectionStats
{
    static int _Read = 0;
    static int _Written = 0;

    public static void Init(bool registerAsSystemProxy = false)
    {
        Fiddler.FiddlerApplication.OnReadRequestBuffer += (s, e) => Interlocked.Add(ref _Written, e.iCountOfBytes);
        Fiddler.FiddlerApplication.OnReadResponseBuffer += (s, e) => Interlocked.Add(ref _Read, e.iCountOfBytes);
        Fiddler.FiddlerApplication.Startup(8088, registerAsSystemProxy, true);
    }

    public static int Read
    {
        get { return _Read; }
    }

    public static int Written
    {
        get { return _Written; }
    }
}

---

WebConnectionStats.Init(); //call this only once

var client = HttpWebRequest.Create("http://stackoverflow.com") as HttpWebRequest;
client.Proxy = new WebProxy("127.0.0.1", 8088);
var resp = client.GetResponse();
var html = new StreamReader(resp.GetResponseStream()).ReadToEnd();

Console.WriteLine("Read: {0}   Write: {1}", WebConnectionStats.Read, 
                                            WebConnectionStats.Written);

PS1::此计数不包括 Tcp标头的长度

I have the below function to fetch a page. My question is i want to calculate how much internet connection is spent

Both inbound (download) and outbound traffic (sent)

How can i do that ? Thank you

My function

 public static string func_fetch_Page(string srUrl, int irTimeOut = 60,
    string srRequestUserAgent = "Mozilla/5.0 (Windows NT 6.3; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0",
    string srProxy = null)
    {
        string srBody = "";
        string srResult = "";
        try
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(srUrl);

            request.Timeout = irTimeOut * 1000;
            request.UserAgent = srRequestUserAgent;
            request.KeepAlive = true;
            request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

            WebHeaderCollection myWebHeaderCollection = request.Headers;
            myWebHeaderCollection.Add("Accept-Language", "en-gb,en;q=0.5");
            myWebHeaderCollection.Add("Accept-Encoding", "gzip, deflate");

            request.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip;

            using (WebResponse response = request.GetResponse())
            {
                using (Stream strumien = response.GetResponseStream())
                {
                    using (StreamReader sr = new StreamReader(strumien))
                    {
                        srBody = sr.ReadToEnd();
                        srResult = "success";
                    }
                }
            }
        }
        catch ()
        {

        }

        return srBody;
    }

@Simon Mourier how do i calculate spent traffic

public static long long_GlobalDownload_KByte = 0;
public static long long_GlobalSent_KByte = 0;

Time  _timer_fetch_download_upload = new Timer(getDownload_Upload_Values, null, 0, 100 * 1000);

public static void getDownload_Upload_Values(Object state)
{
    using (Process p = Process.GetCurrentProcess())
    {
        foreach (var cnx in TcpConnection.GetAll().Where(c => c.ProcessId == p.Id))
        {
            Interlocked.Add(ref long_GlobalDownload_KByte, Convert.ToInt64(cnx.DataBytesIn));
            Interlocked.Add(ref long_GlobalSent_KByte, Convert.ToInt64(cnx.DataBytesOut));
        }
    }
}

解决方案

You can create a proxy using FiddlerCore (just a single dll to reference) and set a WebProxy to your HttpWebRequest to count the sent and received bytes

public class WebConnectionStats
{
    static int _Read = 0;
    static int _Written = 0;

    public static void Init(bool registerAsSystemProxy = false)
    {
        Fiddler.FiddlerApplication.OnReadRequestBuffer += (s, e) => Interlocked.Add(ref _Written, e.iCountOfBytes);
        Fiddler.FiddlerApplication.OnReadResponseBuffer += (s, e) => Interlocked.Add(ref _Read, e.iCountOfBytes);
        Fiddler.FiddlerApplication.Startup(8088, registerAsSystemProxy, true);
    }

    public static int Read
    {
        get { return _Read; }
    }

    public static int Written
    {
        get { return _Written; }
    }
}

WebConnectionStats.Init(); //call this only once

var client = HttpWebRequest.Create("http://stackoverflow.com") as HttpWebRequest;
client.Proxy = new WebProxy("127.0.0.1", 8088);
var resp = client.GetResponse();
var html = new StreamReader(resp.GetResponseStream()).ReadToEnd();

Console.WriteLine("Read: {0}   Write: {1}", WebConnectionStats.Read, 
                                            WebConnectionStats.Written);
