Python HTTP for Humans.
Project description
Requests is the only Non-GMO HTTP library for Python, safe for human consumption.
Warning: Recreational use of the Python standard library for HTTP may result in dangerous side-effects, including: security vulnerabilities, verbose code, reinventing the wheel, constantly reading documentation, depression, headaches, or even death.
Behold, the power of Requests:
>>> r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
>>> r.status_code
200
>>> r.headers['content-type']
'application/json; charset=utf8'
>>> r.encoding
'utf-8'
>>> r.text
u'{"type":"User"...'
>>> r.json()
{u'disk_usage': 368627, u'private_gists': 484, ...}
See the similar code, sans Requests.
Requests allows you to send organic, grass-fed HTTP/1.1 requests, without the need for manual labor. There’s no need to manually add query strings to your URLs, or to form-encode your POST data. Keep-alive and HTTP connection pooling are 100% automatic, thanks to urllib3.
Besides, all the cool kids are doing it. Requests is one of the most downloaded Python packages of all time, pulling in over 11,000,000 downloads every month. You don’t want to be left out!

Release History
2.17.1 (2017-05-29)
Improvements
Improved packages namespace identity support, for monkeypatching libraries.
2.17.0 (2017-05-29)
Improvements
Removal of the 301 redirect cache. This improves thread-safety.
2.16.5 (2017-05-28)
Improvements to $ python -m requests.help.
2.16.4 (2017-05-27)
Introduction of the $ python -m requests.help command, for debugging with maintainers!
2.16.3 (2017-05-27)
Further restored the requests.packages namespace for compatibility reasons.
2.16.2 (2017-05-27)
Further restored the requests.packages namespace for compatibility reasons.
No code modification (noted below) should be neccessary any longer.
2.16.1 (2017-05-27)
Restored the requests.packages namespace for compatibility reasons.
Bugfix for urllib3 version parsing.
Note: code that was written to import against the requests.packages namespace previously will have to import code that rests at this module-level now.
For example:
from requests.packages.urllib3.poolmanager import PoolManager
Will need to be re-written to be:
from requests.packages import urllib3 urllib3.poolmanager.PoolManager
Or, even better:
from urllib3.poolmanager import PoolManager
2.16.0 (2017-05-26)
Unvendor ALL the things!
2.15.1 (2017-05-26)
Everyone makes mistakes.
2.15.0 (2017-05-26)
Improvements
Introduction of the Response.next property, for getting the next PreparedResponse from a redirect chain (when allow_redirects=False).
Internal refactoring of __version__ module.
Bugfixes
Restored once-optional parameter for requests.utils.get_environ_proxies().
2.14.2 (2017-05-10)
Bugfixes
Changed a less-than to an equal-to and an or in the dependency markers to widen compatibility with older setuptools releases.
2.14.1 (2017-05-09)
Bugfixes
Changed the dependency markers to widen compatibility with older pip releases.
2.14.0 (2017-05-09)
Improvements
It is now possible to pass no_proxy as a key to the proxies dictionary to provide handling similar to the NO_PROXY environment variable.
When users provide invalid paths to certificate bundle files or directories Requests now raises IOError, rather than failing at the time of the HTTPS request with a fairly inscrutable certificate validation error.
The behavior of SessionRedirectMixin was slightly altered. resolve_redirects will now detect a redirect by calling get_redirect_target(response) instead of directly querying Response.is_redirect and Response.headers['location']. Advanced users will be able to process malformed redirects more easily.
Changed the internal calculation of elapsed request time to have higher resolution on Windows.
Added win_inet_pton as conditional dependency for the [socks] extra on Windows with Python 2.7.
Changed the proxy bypass implementation on Windows: the proxy bypass check doesn’t use forward and reverse DNS requests anymore
URLs with schemes that begin with http but are not http or https no longer have their host parts forced to lowercase.
Bugfixes
Much improved handling of non-ASCII Location header values in redirects. Fewer UnicodeDecodeErrors are encountered on Python 2, and Python 3 now correctly understands that Latin-1 is unlikely to be the correct encoding.
If an attempt to seek file to find out its length fails, we now appropriately handle that by aborting our content-length calculations.
Restricted HTTPDigestAuth to only respond to auth challenges made on 4XX responses, rather than to all auth challenges.
Fixed some code that was firing DeprecationWarning on Python 3.6.
The dismayed person emoticon (/o\\) no longer has a big head. I’m sure this is what you were all worrying about most.
Miscellaneous
Updated bundled urllib3 to v1.21.1.
Updated bundled chardet to v3.0.2.
Updated bundled idna to v2.5.
Updated bundled certifi to 2017.4.17.
2.13.0 (2017-01-24)
Features
Only load the idna library when we’ve determined we need it. This will save some memory for users.
Miscellaneous
Updated bundled urllib3 to 1.20.
Updated bundled idna to 2.2.
2.12.5 (2017-01-18)
Bugfixes
Fixed an issue with JSON encoding detection, specifically detecting big-endian UTF-32 with BOM.
2.12.4 (2016-12-14)
Bugfixes
Fixed regression from 2.12.2 where non-string types were rejected in the basic auth parameters. While support for this behaviour has been readded, the behaviour is deprecated and will be removed in the future.
2.12.3 (2016-12-01)
Bugfixes
Fixed regression from v2.12.1 for URLs with schemes that begin with “http”. These URLs have historically been processed as though they were HTTP-schemed URLs, and so have had parameters added. This was removed in v2.12.2 in an overzealous attempt to resolve problems with IDNA-encoding those URLs. This change was reverted: the other fixes for IDNA-encoding have been judged to be sufficient to return to the behaviour Requests had before v2.12.0.
2.12.2 (2016-11-30)
Bugfixes
Fixed several issues with IDNA-encoding URLs that are technically invalid but which are widely accepted. Requests will now attempt to IDNA-encode a URL if it can but, if it fails, and the host contains only ASCII characters, it will be passed through optimistically. This will allow users to opt-in to using IDNA2003 themselves if they want to, and will also allow technically invalid but still common hostnames.
Fixed an issue where URLs with leading whitespace would raise InvalidSchema errors.
Fixed an issue where some URLs without the HTTP or HTTPS schemes would still have HTTP URL preparation applied to them.
Fixed an issue where Unicode strings could not be used in basic auth.
Fixed an issue encountered by some Requests plugins where constructing a Response object would cause Response.content to raise an AttributeError.
2.12.1 (2016-11-16)
Bugfixes
Updated setuptools ‘security’ extra for the new PyOpenSSL backend in urllib3.
Miscellaneous
Updated bundled urllib3 to 1.19.1.
2.12.0 (2016-11-15)
Improvements
Updated support for internationalized domain names from IDNA2003 to IDNA2008. This updated support is required for several forms of IDNs and is mandatory for .de domains.
Much improved heuristics for guessing content lengths: Requests will no longer read an entire StringIO into memory.
Much improved logic for recalculating Content-Length headers for PreparedRequest objects.
Improved tolerance for file-like objects that have no tell method but do have a seek method.
Anything that is a subclass of Mapping is now treated like a dictionary by the data= keyword argument.
Requests now tolerates empty passwords in proxy credentials, rather than stripping the credentials.
If a request is made with a file-like object as the body and that request is redirected with a 307 or 308 status code, Requests will now attempt to rewind the body object so it can be replayed.
Bugfixes
When calling response.close, the call to close will be propagated through to non-urllib3 backends.
Fixed issue where the ALL_PROXY environment variable would be preferred over scheme-specific variables like HTTP_PROXY.
Fixed issue where non-UTF8 reason phrases got severely mangled by falling back to decoding using ISO 8859-1 instead.
Fixed a bug where Requests would not correctly correlate cookies set when using custom Host headers if those Host headers did not use the native string type for the platform.
Miscellaneous
Updated bundled urllib3 to 1.19.
Updated bundled certifi certs to 2016.09.26.
2.11.1 (2016-08-17)
Bugfixes
Fixed a bug when using iter_content with decode_unicode=True for streamed bodies would raise AttributeError. This bug was introduced in 2.11.
Strip Content-Type and Transfer-Encoding headers from the header block when following a redirect that transforms the verb from POST/PUT to GET.
2.11.0 (2016-08-08)
Improvements
Added support for the ALL_PROXY environment variable.
Reject header values that contain leading whitespace or newline characters to reduce risk of header smuggling.
Bugfixes
Fixed occasional TypeError when attempting to decode a JSON response that occurred in an error case. Now correctly returns a ValueError.
Requests would incorrectly ignore a non-CIDR IP address in the NO_PROXY environment variables: Requests now treats it as a specific IP.
Fixed a bug when sending JSON data that could cause us to encounter obscure OpenSSL errors in certain network conditions (yes, really).
Added type checks to ensure that iter_content only accepts integers and None for chunk sizes.
Fixed issue where responses whose body had not been fully consumed would have the underlying connection closed but not returned to the connection pool, which could cause Requests to hang in situations where the HTTPAdapter had been configured to use a blocking connection pool.
Miscellaneous
Updated bundled urllib3 to 1.16.
Some previous releases accidentally accepted non-strings as acceptable header values. This release does not.
2.10.0 (2016-04-29)
New Features
SOCKS Proxy Support! (requires PySocks; $ pip install requests[socks])
Miscellaneous
Updated bundled urllib3 to 1.15.1.
2.9.2 (2016-04-29)
Improvements
Change built-in CaseInsensitiveDict (used for headers) to use OrderedDict as its underlying datastore.
Bugfixes
Don’t use redirect_cache if allow_redirects=False
When passed objects that throw exceptions from tell(), send them via chunked transfer encoding instead of failing.
Raise a ProxyError for proxy related connection issues.
2.9.1 (2015-12-21)
Bugfixes
Resolve regression introduced in 2.9.0 that made it impossible to send binary strings as bodies in Python 3.
Fixed errors when calculating cookie expiration dates in certain locales.
Miscellaneous
Updated bundled urllib3 to 1.13.1.
2.9.0 (2015-12-15)
Minor Improvements (Backwards compatible)
The verify keyword argument now supports being passed a path to a directory of CA certificates, not just a single-file bundle.
Warnings are now emitted when sending files opened in text mode.
Added the 511 Network Authentication Required status code to the status code registry.
Bugfixes
For file-like objects that are not seeked to the very beginning, we now send the content length for the number of bytes we will actually read, rather than the total size of the file, allowing partial file uploads.
When uploading file-like objects, if they are empty or have no obvious content length we set Transfer-Encoding: chunked rather than Content-Length: 0.
We correctly receive the response in buffered mode when uploading chunked bodies.
We now handle being passed a query string as a bytestring on Python 3, by decoding it as UTF-8.
Sessions are now closed in all cases (exceptional and not) when using the functional API rather than leaking and waiting for the garbage collector to clean them up.
Correctly handle digest auth headers with a malformed qop directive that contains no token, by treating it the same as if no qop directive was provided at all.
Minor performance improvements when removing specific cookies by name.
Miscellaneous
Updated urllib3 to 1.13.
2.8.1 (2015-10-13)
Bugfixes
Update certificate bundle to match certifi 2015.9.6.2’s weak certificate bundle.
Fix a bug in 2.8.0 where requests would raise ConnectTimeout instead of ConnectionError
When using the PreparedRequest flow, requests will now correctly respect the json parameter. Broken in 2.8.0.
When using the PreparedRequest flow, requests will now correctly handle a Unicode-string method name on Python 2. Broken in 2.8.0.
2.8.0 (2015-10-05)
Minor Improvements (Backwards Compatible)
Requests now supports per-host proxies. This allows the proxies dictionary to have entries of the form {'<scheme>://<hostname>': '<proxy>'}. Host-specific proxies will be used in preference to the previously-supported scheme-specific ones, but the previous syntax will continue to work.
Response.raise_for_status now prints the URL that failed as part of the exception message.
requests.utils.get_netrc_auth now takes an raise_errors kwarg, defaulting to False. When True, errors parsing .netrc files cause exceptions to be thrown.
Change to bundled projects import logic to make it easier to unbundle requests downstream.
Changed the default User-Agent string to avoid leaking data on Linux: now contains only the requests version.
Bugfixes
The json parameter to post() and friends will now only be used if neither data nor files are present, consistent with the documentation.
We now ignore empty fields in the NO_PROXY environment variable.
Fixed problem where httplib.BadStatusLine would get raised if combining stream=True with contextlib.closing.
Prevented bugs where we would attempt to return the same connection back to the connection pool twice when sending a Chunked body.
Miscellaneous minor internal changes.
Digest Auth support is now thread safe.

2.6.0 (2015-03-14)
Bugfixes
CVE-2015-2296: Fix handling of cookies on redirect. Previously a cookie without a host value set would use the hostname for the redirected URL exposing requests users to session fixation attacks and potentially cookie stealing. This was disclosed privately by Matthew Daley of BugFuzz. This affects all versions of requests from v2.1.0 to v2.5.3 (inclusive on both ends).
Fix error when requests is an install_requires dependency and python setup.py test is run. (#2462)

Features and Improvements
Add sha256 fingerprint support. (shazow/urllib3#540)
Improve the performance of headers. (shazow/urllib3#544)
Bugfixes
Copy pip’s import machinery. When downstream redistributors remove requests.packages.urllib3 the import machinery will continue to let those same symbols work. Example usage in requests’ documentation and 3rd-party libraries relying on the vendored copies of urllib3 will work without having to fallback to the system urllib3.
Attempt to quote parts of the URL on redirect if unquoting and then quoting fails. (#2356)
Fix filename type check for multipart form-data uploads. (#2411)

The timeout parameter now affects requests with both stream=True and stream=False equally.
The change in v2.0.0 to mandate explicit proxy schemes has been reverted. Proxy schemes now default to http://.
The CaseInsensitiveDict used for HTTP headers now behaves like a normal dictionary when references as string or viewed in the interpreter.

Keys in the Headers dictionary are now native strings on all Python versions, i.e. bytestrings on Python 2, unicode on Python 3.
Proxy URLs now must have an explicit scheme. A MissingSchema exception will be raised if they don’t.
Timeouts now apply to read time if Stream=False.
RequestException is now a subclass of IOError, not RuntimeError.
Added new method to PreparedRequest objects: PreparedRequest.copy().
Added new method to Session objects: Session.update_request(). This method updates a Request object with the data (e.g. cookies) stored on the Session.
Added new method to Session objects: Session.prepare_request(). This method updates and prepares a Request object, and returns the corresponding PreparedRequest object.
Added new method to HTTPAdapter objects: HTTPAdapter.proxy_headers(). This should not be called directly, but improves the subclass interface.
httplib.IncompleteRead exceptions caused by incorrect chunked encoding will now raise a Requests ChunkedEncodingError instead.
Invalid percent-escape sequences now cause a Requests InvalidURL exception to be raised.
HTTP 208 no longer uses reason phrase "im_used". Correctly uses "already_reported".
