Hello. I'm getting more and more errors from pip on download files: Attempt 1: Downloading https://files.pythonhosted.org/packages/7d/9a/1e93d41708f8ed2b564395edfa3389f0fd6d567597401c2e5e2775118d8b/psutil-5.4.7.tar.gz (420kB) ProtocolErr. The recipe in its current form doesn't work with urllib2 in python 2.5 The reason it fails is that the HTTPConnection.request() method isn't passed the request itself (with the proxy host and port info). urllib2.urlopen('http://foo/url and spaces') will send a HTTP request line like this to the server: GET /url and spaces HTTP/1.1 which the server obviously does not understand. When a proxy is being used by urllib2, the Request's get_selector() will always return the full URL instead of just the selector.

Downloading Files with Python Urllib, Urllib2. Ask Question Asked 8 years, 10 months ago. I am able to download the files (mostly pdf) but all I get is corrupted files that cannot open.

I already know the names of the form fields We get a response object using the urllib2.urlopen() method, where the parameter is the link.

Download HTML This will request the html code from a website. It will output everything to the This post is about how to efficiently/correctly download files from URLs using Python. I will be using the god-send library requests for it. I will write about methods to correctly download binaries from URLs and set their filenames. You can also add headers with "add_header()" syntax: Request.add_header(key, val) urllib2.Request.add_header The example below, use the Mozilla 5.10 as a User Agent, and that is also what will show up in the web server log file. The Python support for fetching resources from the web is layered. urllib2 uses the httplib library, which in turn uses the socket library. As of Python 2.3 you can specify how long a socket should wait for a response before timing out. This can be useful in applications which have to fetch web pages. urllib.request.install_opener (opener) ¶ Install an OpenerDirector instance as the default global opener. Installing an opener is only necessary if you want urlopen to use that opener; otherwise, simply call OpenerDirector.open() instead of urlopen().The code does not check for a real OpenerDirector, and any class with the appropriate interface will work.
