HTTPX - A next-generation HTTP client for Python.

+ +

+ + Test Suite + + + Package version + +

+ +HTTPX is a fully featured HTTP client library for Python 3. It includes **an integrated command line client**, has support for both **HTTP/1.1 and HTTP/2**, and provides both **sync and async APIs**. + +--- + +Install HTTPX using pip: + +```shell +$ pip install httpx +``` + +Now, let's get started: + +```pycon +>>> import httpx +>>> r = httpx.get('https://www.example.org/') +>>> r + +>>> r.status_code +200 +>>> r.headers['content-type'] +'text/html; charset=UTF-8' +>>> r.text +'\n\n\nExample Domain...' +``` + +Or, using the command-line client. + +```shell +$ pip install 'httpx[cli]' # The command line client is an optional dependency. +``` + +Which now allows us to use HTTPX directly from the command-line... + +

+ httpx --help +

+ httpx http://httpbin.org/json +

+ +## Features + +HTTPX builds on the well-established usability of `requests`, and gives you: + +* A broadly [requests-compatible API](https://www.python-httpx.org/compatibility/). +* An integrated command-line client. +* HTTP/1.1 [and HTTP/2 support](https://www.python-httpx.org/http2/). +* Standard synchronous interface, but with [async support if you need it](https://www.python-httpx.org/async/). +* Ability to make requests directly to [WSGI applications](https://www.python-httpx.org/advanced/transports/#wsgi-transport) or [ASGI applications](https://www.python-httpx.org/advanced/transports/#asgi-transport). +* Strict timeouts everywhere. +* Fully type annotated. +* 100% test coverage. + +Plus all the standard features of `requests`... + +* International Domains and URLs +* Keep-Alive & Connection Pooling +* Sessions with Cookie Persistence +* Browser-style SSL Verification +* Basic/Digest Authentication +* Elegant Key/Value Cookies +* Automatic Decompression +* Automatic Content Decoding +* Unicode Response Bodies +* Multipart File Uploads +* HTTP(S) Proxy Support +* Connection Timeouts +* Streaming Downloads +* .netrc Support +* Chunked Requests + +## Installation + +Install with pip: + +```shell +$ pip install httpx +``` + +Or, to include the optional HTTP/2 support, use: + +```shell +$ pip install httpx[http2] +``` + +HTTPX requires Python 3.8+. + +## Documentation + +Project documentation is available at [https://www.python-httpx.org/](https://www.python-httpx.org/). + +For a run-through of all the basics, head over to the [QuickStart](https://www.python-httpx.org/quickstart/). + +For more advanced topics, see the [Advanced Usage](https://www.python-httpx.org/advanced/) section, the [async support](https://www.python-httpx.org/async/) section, or the [HTTP/2](https://www.python-httpx.org/http2/) section. + +The [Developer Interface](https://www.python-httpx.org/api/) provides a comprehensive API reference. + +To find out about tools that integrate with HTTPX, see [Third Party Packages](https://www.python-httpx.org/third_party_packages/). + +## Contribute + +If you want to contribute with HTTPX check out the [Contributing Guide](https://www.python-httpx.org/contributing/) to learn how to start. + +## Dependencies + +The HTTPX project relies on these excellent libraries: + +* `httpcore` - The underlying transport implementation for `httpx`. + * `h11` - HTTP/1.1 support. +* `certifi` - SSL certificates. +* `idna` - Internationalized domain name support. +* `sniffio` - Async library autodetection. + +As well as these optional installs: + +* `h2` - HTTP/2 support. *(Optional, with `httpx[http2]`)* +* `socksio` - SOCKS proxy support. *(Optional, with `httpx[socks]`)* +* `rich` - Rich terminal support. *(Optional, with `httpx[cli]`)* +* `click` - Command line client support. *(Optional, with `httpx[cli]`)* +* `brotli` or `brotlicffi` - Decoding for "brotli" compressed responses. *(Optional, with `httpx[brotli]`)* +* `zstandard` - Decoding for "zstd" compressed responses. *(Optional, with `httpx[zstd]`)* + +A huge amount of credit is due to `requests` for the API layout that +much of this work follows, as well as to `urllib3` for plenty of design +inspiration around the lower-level networking details. + +--- + +

HTTPX is BSD licensed code.
Designed & crafted with care.

+Provides-Extra: all + +# Internationalized Domain Names in Applications (IDNA) + +Support for [Internationalized Domain Names in Applications +(IDNA)](https://tools.ietf.org/html/rfc5891) and [Unicode IDNA +Compatibility Processing](https://unicode.org/reports/tr46/). It +supersedes the standard library's `encodings.idna`, which only +implements the 2003 specification, offering broader script coverage and +limiting domains with known security vulnerabilities. + +## Usage + +Package may be installed from [PyPI](https://pypi.org/project/idna/) via +the typical methods (e.g. `python3 -m pip install idna`) + +For typical usage, the `encode` and `decode` functions will take a +domain name argument and perform a conversion to ASCII-compatible encoding +(known as A-labels), or to Unicode strings (known as U-labels) +respectively. + +```pycon +>>> import idna +>>> idna.encode('ドメイン.テスト') +b'xn--eckwd4c7c.xn--zckzah' +>>> print(idna.decode('xn--eckwd4c7c.xn--zckzah')) +ドメイン.テスト +``` + +Conversions can be applied at a per-label basis using the `ulabel` or +`alabel` functions for specialized use cases. + + +### Compatibility Mapping (UTS #46) + +This library provides support for [Unicode IDNA Compatibility +Processing](https://unicode.org/reports/tr46/) which normalizes input from +different potential ways a user may input a domain prior to performing the IDNA +conversion operations. This functionality, known as a +[mapping](https://tools.ietf.org/html/rfc5895), is considered by the +specification to be a local user-interface issue distinct from IDNA +conversion functionality. + +For example, "Königsgäßchen" is not a permissible label as capital letters +are not allowed. UTS 46 will convert this into lower case prior to applying +the IDNA conversion. + +```pycon +>>> import idna +>>> idna.encode('Königsgäßchen') +... +idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of 'Königsgäßchen' not allowed +>>> idna.encode('Königsgäßchen', uts46=True) +b'xn--knigsgchen-b4a3dun' +>>> idna.decode('xn--knigsgchen-b4a3dun') +'königsgäßchen' +``` + +When performing a decode operation for display purposes, `decode()` +accepts a `display=True` argument that leaves any `xn--` label that +fails to decode unchanged. This is useful for user interface display +where a domain is in use, the A-label form can be presented when it +is not a valid IDN. + + +## Exceptions + +All errors raised during conversion derive from the `idna.IDNAError` +base class. The more specific exceptions are: + +* `idna.IDNABidiError` — raised when a label contains an illegal + combination of left-to-right and right-to-left characters. +* `idna.InvalidCodepoint` — raised when a label contains a codepoint + that is INVALID for IDNA. +* `idna.InvalidCodepointContext` — raised when a CONTEXTO or CONTEXTJ + codepoint appears in a position whose contextual requirements are + not satisfied. + + +## Command-line tool + +The package supports command-line usage to convert domain names +between their Unicode and ASCII-compatible forms. It can be run either +as a module (`python3 -m idna`) or, once installed (such as with `uv +tool` or `pipx`), via the `idna` script: + +```bash +$ uv tool install idna +$ idna xn--e1afmkfd.xn--p1ai +пример.рф +$ idna пример.рф +xn--e1afmkfd.xn--p1ai +``` + +Mode can be specified with `-e`/`--encode` or `-d`/`--decode`, otherwise +it will be chosen automatically based on the first input. Multiple +domains can be supplied either as arguments or through standard input. +UTS #46 mapping is applied by default, which lets the tool accept +inputs that aren't strictly valid IDNA 2008 by normalising them first, +pass `--strict` to disable UTS #46. + +Conversion failures are reported on stderr together with the +offending input; processing continues with the remaining domains and +the tool exits with a non-zero status if any conversion failed. + + +## Additional Notes + +* **Version support**. This library supports Python 3.9 and higher. + As this library serves as a low-level toolkit for a variety of + applications, we strive to support all versions of Python that are + not beyond end-of-life. + +* **Emoji**.

+======================================================= + +iniconfig is a small and simple INI-file parser module +having a unique set of features: + +* maintains order of sections and entries +* supports multi-line values with or without line-continuations +* supports "#" comments everywhere +* raises errors with proper line-numbers +* no bells and whistles like automatic substitutions +* iniconfig raises an Error if two sections have the same name. + +If you encounter issues or have feature wishes please report them to: + + https://github.com/RonnyPfannschmidt/iniconfig/issues + +Basic Example +=================================== + +If you have an ini file like this: + +.. code-block:: ini + + # content of example.ini + [section1] # comment + name1=value1 # comment + name1b=value1,value2 # comment + + [section2] + name2= + line1 + line2 + +then you can do: + +.. code-block:: pycon + + >>> import iniconfig + >>> ini = iniconfig.IniConfig("example.ini") + >>>
