我试图制作一个表单导航程序，我想知道如何制作 GET httpwebrequest 这是我用于 POST httpwebrequest 的代码
Dim postData As String = "lsd=AVrFBNXT&display=&enable_profile_selector=&legacy_return=1&next=&profile_selector_ids=&trynum=1&timezone=-120&lgnrnd=163248_FehM&lgnjs=1372203160&email=" & (TextBox1.Text) & "&pass=" & (TextBox2.Text) & "f&default_persistent=1"
Dim tempcookies As New CookieContainer
Dim encoding As New UTF8Encoding
Dim byteData As Byte() = encoding.GetBytes(postData)
Dim postreq As HttpWebRequest = DirectCast(HttpWebRequest.Create("https://www.facebook.com/login.php"), HttpWebRequest)
postreq.Method = "POST"
postreq.KeepAlive = True
postreq.CookieContainer = tempcookies
postreq.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; ru; rv:1.9.2.3) Gecko/20100401 Firefox/4.0 (.NET CLR 3.5.30729"
postreq.ContentType = "application/x-www-form-urlencoded"
postreq.Referer = "https://www.facebook.com/login.php"
postreq.ContentLength = byteData.Length
Dim postreqstream As Stream = postreq.GetRequestStream()
postreqstream.Write(byteData, 0, byteData.Length)
postreqstream.Close()
Dim postresponse As HttpWebResponse
postresponse = DirectCast(postreq.GetResponse, HttpWebResponse)
tempcookies.Add(postresponse.Cookies)
logincookie = tempcookies
Dim postreqreader As New StreamReader(postresponse.GetResponseStream())
Dim thepage As String = postreqreader.ReadToEnd
WebBrowser1.DocumentText = thepage
最佳答案
您可以将方法更改为“GET”并删除请求流:
Dim postData As String = "lsd=AVrFBNXT&display=&enable_profile_selector=&legacy_return=1&next=&profile_selector_ids=&trynum=1&timezone=-120&lgnrnd=163248_FehM&lgnjs=1372203160&email=" & (TextBox1.Text) & "&pass=" & (TextBox2.Text) & "f&default_persistent=1"
Dim tempcookies As New CookieContainer
Dim encoding As New UTF8Encoding
Dim byteData As Byte() = encoding.GetBytes(postData)
Dim postreq As HttpWebRequest = DirectCast(HttpWebRequest.Create("https://www.facebook.com/login.php"), HttpWebRequest)
postreq.Method = "GET"
postreq.KeepAlive = True
postreq.CookieContainer = tempcookies
postreq.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.1; ru; rv:1.9.2.3) Gecko/20100401 Firefox/4.0 (.NET CLR 3.5.30729"
postreq.ContentType = "application/x-www-form-urlencoded"
postreq.Referer = "https://www.facebook.com/login.php"
Dim postresponse As HttpWebResponse
postresponse = DirectCast(postreq.GetResponse, HttpWebResponse)
tempcookies.Add(postresponse.Cookies)
logincookie = tempcookies
Dim postreqreader As New StreamReader(postresponse.GetResponseStream())
Dim thepage As String = postreqreader.ReadToEnd
WebBrowser1.DocumentText = thepage
