urllib2问题求助

Question

python里的urllib2.request怎么判断是get请求还是post请求啊 就是我自己传一个url进去 我怎么知道这次是进行post还是get请求呢？

Answer 1

根据python官方文档的描述：

class urllib2.Request(url[, data][, headers][, origin_req_host][, unverifiable])

This class is an abstraction of a URL request.

url should be a string containing a valid URL.

data may be a string specifying additional data to send to the server, or None if no such data is needed. Currently HTTP requests are the only ones that use data; the HTTP request will be a POST instead of a GET when the data parameter is provided. data should be a buffer in the standard application/x-www-form-urlencoded format. The urllib.urlencode() function takes a mapping or sequence of 2-tuples and returns a string in this format.

如果data参数值为None或者没有传data参数，那么就是get请求，否则就是post请求
