Open Source Python HTTP Clients

Asynchronous HTTP Client/Server for asyncio and Python. AIOHTTP supports both client and server side of HTTP protocol. A long awaited new feature is tracing client request life cycle to figure out when and why client request spends a time waiting for connection establishment, getting server response headers etc. Now it is possible by registering special signal handlers on every request processing stage. The main change is dropping yield from support and using async/await everywhere. Farewell, Python 3.4. You often want to send some sort of data in the URL’s query string. If you were constructing the URL by hand, this data would be given as key/value pairs in the URL after a question mark, e.g. httpbin.org/get?key=val. Requests allows you to provide these arguments as a dict, using the params keyword argument. aiohttp internally performs URL canonicalization before sending request.

urllib3 is a powerful, user-friendly HTTP client for Python. Much of the Python ecosystem already uses urllib3 and you should too. Thread safety, connection pooling. Client-side TLS/SSL verification. File uploads with multipart encoding. Helpers for retrying requests and dealing with HTTP redirects. Support for gzip, deflate, brotli, and zstd encoding. Proxy support for HTTP and SOCKS. 100% test coverage. Professional support for urllib3 is available as part of the Tidelift Subscription. Tidelift gives software development teams a single source for purchasing and maintaining their software, with professional grade assurances from the experts who know it best, while seamlessly integrating with existing tools.

Automatically mock your HTTP interactions to simplify and speed up testing. VCR.py simplifies and speeds up tests that make HTTP requests. The first time you run code that is inside a VCR.py context manager or decorated function, VCR.py records all HTTP interactions that take place through the libraries it supports and serializes and writes them to a flat file (in yaml format by default). This flat file is called a cassette. When the relevant piece of code is executed again, VCR.py will read the serialized requests and responses from the aforementioned cassette file, and intercept any HTTP requests that it recognizes from the original test run and return the responses that corresponded to those requests. This means that the requests will not actually result in HTTP traffic, which confers several benefits including:

`Whakerexa` provides a lightweight, modular set of CSS and JavaScript tools for building accessible, consistent, and customizable web interfaces. It is intended to be as simple as possible to make **accessible web content**, and to minimize the use of CSS classes for enhancing the readability of HTML code. It was designed to be easily customizable, allowing users to adjust properties such as fonts, colors, borders, etc., effortlessly. Most of the properties are stored into variables which makes possible to re-define them, then to obtain a custom different style, enabling users to achieve a unique style easily. It can be combined with the use of WhakerPy, an open source library to create dynamic HTML content: <https://whakerpy.sf.net>. Features: - Lightweight and semantic - Light or dark mode - Normal or high-Contrast mode - Easy use and customization - Human-readable: could be extended or composed for your specific needs - No extr

Using Socks4/5 or http proxies to make a multithreading Http-flood/Https-flood (cc) attack.

This is a proof of concept for CVE-2021-31166 ("HTTP Protocol Stack Remote Code Execution Vulnerability"), a use-after-free dereference in http.sys patched by Microsoft in May 2021. The bug itself happens in http!UlpParseContentCoding where the function has a local LIST_ENTRY and appends an item to it. When it's done, it moves it into the Request structure; but it doesn't NULL out the local list. The issue with that is that an attacker can trigger a code-path that frees every entry of the local list leaving them dangling in the Request object.

LinkChecker is a free, GPL licensed website validator. LinkChecker checks links in web documents or full websites. It runs on Python 3 systems, requiring Python 3.8 or later. The version in the pip repository may be old, to find out how to get the latest code, plus platform-specific information and other advice see doc/install.txt in the source code archive. If you do not want to install any additional libraries/dependencies you can use the Docker image which is published on GitHub Packages.

requests-cache is a persistent HTTP cache that provides an easy way to get better performance with the Python requests library. Keep using the requests library you’re already familiar with. Add caching with a drop-in replacement for requests. The session, or install globally to add transparent caching to all request functions. Get sub-millisecond response times for cached responses. When they expire, you still save time with conditional requests. Works with several storage backends including SQLite, Redis, MongoDB, and DynamoDB; or save responses as plain JSON files, YAML, and more. Use Cache-Control and other standard HTTP headers, define your own expiration schedule, and keep your cache clutter-free with backends that natively support TTL or any combination of strategies. Works out of the box with zero config, but with a robust set of features for configuring and extending the library to suit your needs.
