问题 Is it possible using urllib or urllib2 to send no data with a POST request? Sounds odd, but the API I am using sends blank data in the POST request. I've tried the following, but it seems to be issuing a GET request because of no POST data. url = 'https://site.com/registerclaim?cid=' + int(cid) values = {} headers = { 'User-Agent' : 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36', 'X-CRFS-Token' : csrfToken, 'X

问题 So I have this program which requests a file from the web and the user can download it. I am using urllib.request and tkinter for my program. The problem is that when the user hits the 'Download' button there is no pause or cancel until the file gets downloaded and the program freezes too.

问题 I have a doubt. st = "b%C3%BCrokommunikation" urllib2.unquote(st) OUTPUT: 'b\xc3\xbcrokommunikation' But, if I print it: print urllib2.unquote(st) OUTPUT: bürokommunikation Why is the difference? I have to write bürokommunikation instead of 'b\xc3\xbcrokommunikation' into a file. My problem is: I have lots of data with such values extracted from URLs. I have to store them as eg. bürokommunikation into a text file. 回答1: When you print the string, your terminal emulator recognizes the unicode
