urllib.request.Request python2 如何实现

In Python 2, the equivalent of urllib.request.Request is urllib2.Request.

Here’s an example:

import urllib2

url = "https://example.com"
headers = {"User-Agent": "My User Agent"}
data = "foo=bar&baz=qux"

req = urllib2.Request(url, data, headers)
response = urllib2.urlopen(req)

print(response.read())

This code creates a Request object with the specified URL, data, and headers, and then uses urlopen to send the request and get the response.

Note that in Python 2, urllib2 is used instead of urllib.request, and the Request class is used to create a request object.

In Python 3.x, urllib.request.Request is used to create a request object, and it’s much simpler to use. For example:

import urllib.request

url = "https://example.com"
headers = {"User-Agent": "My User Agent"}
data = "foo=bar&baz=qux"

req = urllib.request.Request(url, data.encode("utf-8"), headers)
response = urllib.request.urlopen(req)

print(response.read().decode("utf-8"))

This code creates a Request object with the specified URL, data, and headers, and then uses urlopen to send the request and get the response.
