【關於header信息的構造】Python模擬登陸出現亂碼

使用Python模擬登陸Z-Blog系統的後臺時，若是構造的header信息以下，那麼獲得的結果將會亂碼，以下圖所示

對應的錯誤的header信息以下：

url = "http://192.168.1.11/cmd.asp?act=verify"
    request = urllib2.Request(url)
    request.add_header("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64; rv:26.0) Gecko/20100101 Firefox/26.0")
    request.add_header("Host","192.168.1.11")    request.add_header("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
    request.add_header("Accept-Language","zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3")
    request.add_header("Accept-Encoding","gzip, deflate")
    request.add_header("Referer","http://192.168.1.11/login.asp")
    request.add_header("Cookie","ASPSESSIONIDQABAQQRA=; username=admin; password=XXX; ASPSESSIONIDQCBBQQQB=XXX")
    request.add_header("Connection","keep-alive")
    f = urllib2.urlopen(request)
    print f.read()

問題處在：

request.add_header("Accept-Encoding","gzip, deflate")

只需刪除該條header信息便可
具體緣由，還沒細看，先解決問題，後面再好好研究下
