直接上代码

import urllib.requestimport urllib.parsedef request():    #定义 HTTP的头部    headers = {'User-Agent':'Mozilla/5.0','x-my-header':'my value'}    req = urllib.request.Request('http://blog.kamidox.com',headers = headers)    s = urllib.request.urlopen(req)    print(s.read(100))    print(req.headers)    s.close()    def request_post_debug():    #post    data = {'username':'kamidox','password':'xxxxxxx'}    headers = {'User-Agent':'Mozilla/5.0'}      req = urllib.request.Request('http://www.douban.com',data  = urllib.parse.urlencode(data),headers = headers)        #创建一个打开器    opener = urllib.request.build_opener(urllib.request.HTTPHandler(debuglevel = 1))    s = opener.open(req)    print(s.read(100))    s.close()if __name__=='__main__':    request_post_debug()

看了好久没看出错误，最后无意间在网上发现答案，分享给大家，

Request('http://www.douban.com',data  = urllib.parse.urlencode(data).encode(encoding='UTF8'),headers = headers)

大家对照一下找不同就解决了哈哈。
