使用带有 Python 请求库的 get 方法的标头

Question

So I recently stumbled upon this great library for handling HTTP requests in Python; found here http://docs.python-requests.org/en/latest/index.html .

I love working with it, but I can't figure out how to add headers to my get requests. Help?

Answer 1

According to the API , the headers can all be passed in using requests.get :

import requests
r=requests.get("http://www.example.com/", headers={"content-type":"text"})

Answer 2

Seems pretty straightforward, according to the docs on the page you linked (emphasis mine).

requests.get(url, params=None, headers=None, cookies=None, auth=None, timeout=None)

Sends a GET request. Returns Response object.

Parameters:

• url – URL for the new Request object.
• params – (optional) Dictionary of GET Parameters to send with the Request .
• headers – (optional) Dictionary of HTTP Headers to send with the Request .
• cookies – (optional) CookieJar object to send with the Request .
• auth – (optional) AuthObject to enable Basic HTTP Auth.
• timeout – (optional) Float describing the timeout of the request.

Answer 3

This answer taught me that you can set headers for an entire session:

s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})

# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})

Bonus: Sessions also handle cookies.

Answer 4

1. Go to http://myhttpheader.com
2. copy attributes - typically 'Accept-Language' and 'User-Agent'.
3. Wrap them in the dictionary:

headers = { 'Accept-Language': content-copied-from-myhttpheader, 'User-Agent':content-copied-from-myhttpheader}

4. pass headers in your request requests.get(url=your_url,headers=headers)
