Putting a `Cookie` in a `CookieJar`

由 前提是你 提交于 2019-11-27 11:47:01
I'm using the new Python Requests library to make http requests. I obtain a cookie from the server as text. How do I turn that into a CookieJar with the cookie in it? dstanek I'm confused by this question. The requests library will put the cookies in the jar for you. import requests import cookielib URL = '...whatever...' jar = cookielib.CookieJar() r = requests.get(URL, cookies=jar) r = requests.get(URL, cookies=jar) The first request to the URL will fill the jar. The second request will send the cookies back to the server. The same goes for the standard library's urllib module cookielib .

How secure is HTTP_ORIGIN?

由 烂漫一生 提交于 2019-11-27 03:44:56
I want to find out whether an incoming HTTP_REQUEST call from a third party website is coming from the list of domains that I defined. I know that HTTP_REFERER can be used to find out where the third party domain is, but it is not secure enough. People can spoof it or use Telnet to fake it. So, how about HTTP_ORIGIN? Is it sent from all browsers? Is it secure? Also, can people fake the REMOTE_ADDR in a HTTP_REQUEST call? HTTP_ORIGIN is a way to protect against CSRF (Cross Site Request Forgery) requests. Currently it is implemented only by Chrome (as of Nov 2011). I tested Firefox and Opera -

HTTP status code for unaccepted Content-Type in request

由 半世苍凉 提交于 2019-11-27 03:42:53
问题 For certain resources, my RESTful server only accepts PUT and POST requests with JSON objects as the content body, thus requiring a Content-Type of application/json instead of application/x-www-form-urlencoded or multipart/form-data or anything else. Malformed JSON (or lack thereof) returns a 400 with the error message taken directly from the exception raised by the JSON parser, for debugging purposes. Which HTTP error code means that the client sent a request with an unacceptable Content

When should one use CONNECT and GET HTTP methods at HTTP Proxy Server?

由 匆匆过客 提交于 2019-11-27 00:08:35
问题 I'm building a WebClient library. Now I'm implementing a proxy feature, so I am making some research and I saw some code using the CONNECT method to request a URL. But checking it within my web browser, it doesn't use the CONNECT method but calls the GET method instead. So I'm confused. When I should use both methods? 回答1: A CONNECT request urges your proxy to establish an HTTP tunnel to the remote end-point. Usually is it used for SSL connections, though it can be used with HTTP as well

Getting HEAD content with Python Requests

由 試著忘記壹切 提交于 2019-11-26 20:24:27
问题 I'm trying to parse the result of a HEAD request done using the Python Requests library, but can't seem to access the response content. According to the docs, I should be able to access the content from requests.Response.text. This works fine for me on GET requests, but returns None on HEAD requests. GET request (works) import requests response = requests.get(url) content = response.text content = <html>...</html> HEAD request (no content) import requests response = requests.head(url) content
