自定义http报头_Http请求报头设置

1.添加一个SetHeaderValue方法：

public static void SetHeaderValue(WebHeaderCollection header, string name, string value)

{

var property = typeof(WebHeaderCollection).GetProperty("InnerCollection",BindingFlags.Instance | BindingFlags.NonPublic);

if (property != null)

{

var collection = property.GetValue(header, null) as NameValueCollection;

collection[name] = value;

}

}

2.调用这个方法设置HttpHeader头：

HttpWebRequest rq = (HttpWebRequest)WebRequest.Create("Url");

rq.Method = "GET";

SetHeaderValue(rq.Headers, "Host", "127.0.0.1");

SetHeaderValue(rq.Headers, "Connection", "keep-alive");

SetHeaderValue(rq.Headers, "Accept", "*/*");

SetHeaderValue(rq.Headers, "X-Requested-With", "XMLHttpRequest");

SetHeaderValue(rq.Headers, "User-Agent", "...");

SetHeaderValue(rq.Headers, "Referer", "http://127.0.0.1/index.php?m=Index&a=indexs");

SetHeaderValue(rq.Headers, "Accept-Encoding", "gzip, deflate");

SetHeaderValue(rq.Headers, "Accept-Language", "1.5");

SetHeaderValue(rq.Headers, "Cookie", "This is Cookie");

HttpWebResponse resp = (HttpWebResponse)rq.GetResponse();

using (Stream stream = resp.GetResponseStream())

{

StreamReader reader =new StreamReader(stream,Encoding.Default);

string responseString = reader.ReadToEnd();

MessageBox.Show(responseString);

}

3.可以通过抓包软件(如SRSniffer)查看到设置的报头.
