Question

编辑：我更改了代码，但仍然无效！我使用答案中的链接来做，但它没有用！

为什么这不起作用？当我运行它需要很长时间才能运行并且永远不会完成！

import urllib
import urllib2



url = 'https://www.locationary.com/index.jsp?ACTION_TOKEN=tile_loginBar_jsp$JspView$LoginAction'



values = {'inUserName' : 'USER',
          'inUserPass' : 'PASSWORD'}
data = urllib.urlencode(values)


req = urllib2.Request(url, data)

#headers = { 'User-Agent' : user_agent }



response = urllib2.urlopen(req)
page = response.read()


print page

Answer 1

远程服务器（www.locationary.com上的服务器）正在等待HTTP发布请求的内容，具体取决于Content-Type和Content-Length标头。由于您实际上从未发送过所述等待的数据，因此远程服务器会等待 - read()也是如此 - 直到您这样做。

我需要知道如何发送我的http发布请求的内容。

嗯，您需要在请求中实际发送一些数据。参见：

最终，“工作”版本：

import urllib
import urllib2

url = 'https://www.locationary.com/index.jsp?ACTION_TOKEN=tile_loginBar_jsp$JspView$LoginAction'

values = {'inUserName' : 'USER',
          'inUserPass' : 'PASSWORD'}

data = urllib.urlencode(values)
req = urllib2.Request(url, data)

req.add_header('Host', 'www.locationary.com')
req.add_header('User-Agent', 'Mozilla/5.0 (Windows NT 6.1; rv:8.0) Gecko/20100101 Firefox/8.0')
req.add_header('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8')
req.add_header('Accept-Language', 'en-us,en;q=0.5')
req.add_header('Accept-Charset','ISO-8859-1,utf-8;q=0.7,*;q=0.7')
req.add_header('Connection','keep-alive')
req.add_header('Referer','http://www.locationary.com/')
req.add_header('Cookie','site_version=REGULAR; __utma=47547066.1079503560.1321924193.1322707232.1324693472.36; __utmz=47547066.1321924193.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); nickname=jacob501; locaCountry=1033; locaState=1795; locaCity=Montreal; jforumUserId=1; PMS=1; TurnOFfTips=true; Locacookie=enable; __utma=47547066.1079503560.1321924193.1322707232.1324693472.36; __utmz=47547066.1321924193.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); nickname=jacob501; PMS=1; __utmb=47547066.15.10.1324693472; __utmc=47547066; JSESSIONID=DC7F5AB08264A51FBCDB836393CB16E7; PSESSIONID=28b334905ab6305f7a7fe051e83857bc280af1a9; __utmc=47547066; __utmb=47547066.15.10.1324693472; ACTION_RESULT_CODE=ACTION_RESULT_FAIL; ACTION_ERROR_TEXT=java.lang.NullPointerException')
req.add_header('Content-Type','application/x-www-form-urlencoded')

response = urllib2.urlopen(req)
page = response.read()

print page

不要显式设置Content-Length标头
删除req.add_header('Accept-Encoding','gzip, deflate')行，以便不必解压缩响应（或者 - 留给读者 - 自己解压缩）

为什么我的Python程序不起作用？它使用HTTP标头
