HTTP 400上的語法幫助urllib2.urlopen上的錯誤請求響應

我有一段代碼，我登錄到一個網站 - 通過代理服務器並使用網站憑據。我登錄很好。然後我嘗試進入一個頁面，在那裏我發送了會話Id，Cookie看起來好像是，但是我收到了HTTP 400 Bad Request。請參閱我的請求的語法，並讓我知道我錯過了什麼。我真的很感激任何反饋！HTTP 400上的語法幫助urllib2.urlopen上的錯誤請求響應

非常感謝提前，伊戈爾

import urllib, urllib2, cookielib 
proxy_info = { 
'user' : 'myuser', 
'pass' : 'mypassword', 
'host' : "myproxy.company.com", 
'port' : 8080 
} 

proxy_support = urllib2.ProxyHandler({"http" : "http://%(user)s:%(pass)[email protected]%(host)s:%(port)d" % proxy_info}) 

cj = cookielib.CookieJar() 
cookie_h = urllib2.HTTPCookieProcessor(cj) 
opener = urllib2.build_opener(proxy_support, urllib2.HTTPHandler(debuglevel=1) , cookie_h) 
headers={'User-agent' : 'Mozilla/5.0'}  

urllib2.install_opener(opener)  
url = 'http://www.targetsite.com/LogIn.asp?user_id=&user_p assword=myapppassword' 
f = urllib2.urlopen(url) 
html = f.read() 
print html 
url2 = 'http://www.targetsite.com/Main.asp?uid=&sid=3294799 60 HTTP/1.1' 
response = urllib2.urlopen (url2) 
html2 = response.read() 
print html2

我得到這個回：

url，url2是無效的。嘗試：

url = 'http://www.targetsite.com/LogIn.asp?' + urllib.urlencode(
    {"user_id": "", "user_p assword": "myapppassword"}) 
url2 = 'http://www.targetsite.com/Main.asp?' + urllib.urlencode(
    {"uid": "", "sid": "3294799 60 HTTP/1.1"})

名稱user_p assword不應可能包含空格。此外，sid的值似乎是可疑的。這可能是一個複製粘貼錯誤。

你爲什麼要在第二個URL中發送「HTTP/1.1」？該語法似乎不是有效的，ulrlib2無論如何都會發送HTTP/1.1。從痕跡來看，這看起來是問題所在。
