AIOHTTP
Asynchronous HTTP client/server framework for asyncio and Python
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. -

Interactsh
An OOB interaction gathering server and client library
Interactsh is an open-source tool for detecting out-of-band interactions. It is a tool designed to detect vulnerabilities that cause external interactions. Interactsh Cli client requires go1.17+ to install successfully. interactsh-client with -sf, -session-file flag can be used store/read the current session information from user defined file which is useful to resume the same session to poll the interactions even after the client gets stopped or closed. Running the interactsh-client in verbose mode (v) to see the whole request and response, along with an output file to analyze afterwards. Using the server flag, interactsh-client can be configured to connect with a self-hosted Interactsh server, this flag accepts single or multiple server separated by comma. Default servers are subject to change/rotate/down at any time, thus we recommend using a self-hosted interactsh server if you are experiencing issues with the default server. -

Milkman
An extensible request/response workbench
Milkman is heavily inspired by Postman. But I got sick of all those electron-based applications that need ages and loads of memory to start up. Therefore, this is a JavaFx-based workbench for crafting requests/responses. It is not limited to e.g. HTTP (or more specifically rest) requests. Due to nearly everything being a plugin, other things are possible, like database requests or GRPC, GraphQl, etc. Request-types (e.g. Http Request), request-aspects (e.g. Headers, Body, etc), editors for request aspects (e.g. table-based editors for headers), importers, whatever it is, you can extend it. The core application only handles Workspaces with Environments, Collections, Requests, and their aspects. Several plugins are provided already that extend the core application to be a replacement for postman. Crafting and Executing Http/Rest requests with json highlighting. Support Proxy-server configuration and SSE. -

pgrok
HTTP/TCP reverse tunnel solution through SSH remote port forwarding
The pgrok is a multi-tenant HTTP/TCP reverse tunnel solution through remote port forwarding from the SSH protocol. This is intended for small teams that need to expose the local development environment to the public internet, and you need to bring your own domain name and SSO provider. It gives a stable subdomain for every user and gated by your SSO through the OIDC protocol. Think of this as a bare-bones alternative to the ngrok's $65/user/month enterprise tier. Trying to put this behind a production system will blow up your SLA. For individuals and production systems, just buy ngrok, it is still my favorite. -

RESTinio
HTTP/WebSocket server C++14 library
RESTinio is a header-only C++14 library that gives you an embedded HTTP/WebSocket server. It is based on the standalone version of ASIO and is targeted primarily for the asynchronous processing of HTTP requests. Since v.0.4.1 Boost::ASIO (1.66 or higher) is also supported. Consider the task of writing a C++ application that must support some REST API, RESTinio represents our solution for that task. Server runs on the main thread, and responds to all requests with a hello-world message. Of course, you've got access to the structure of a given HTTP request, so you can apply complex logic for handling requests. Async request handling. Cannot get the response data immediately? That's ok, store the request handle somewhere and/or pass it to another execution context and get back to it when the data is ready. -

sish
HTTP(S)/WS(S)/TCP Tunnels to localhost using only SSH
An open source serveo/ngrok alternative. Builds are made automatically for each commit to the repo and are pushed to Dockerhub. Builds are tagged using a commit sha, branch name, tag, latest if released on main. Each release builds separate sish binaries that can be downloaded from here for various OS/archs. Feel free to either use the automated binaries or to build your own. If you submit a PR, images are not built by default and will require a retag from a maintainer to be built. You can also use Docker Compose to setup your sish instance. This includes taking care of SSL via Let's Encrypt for you. This uses the adferrand/dnsrobocert container to handle issuing wildcard certifications over DNS. SSH can normally forward local and remote ports. This service implements an SSH server that only handles forwarding and nothing else. The service supports multiplexing connections over HTTP/HTTPS with WebSocket support. -

OpenAPI.NET
Object model for OpenAPI documents in .NET
The OpenAPI.NET SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model. The OpenAPI.NET project holds the base object model for representing OpenAPI documents as .NET objects. Some developers have found the need to write processors that convert other data formats into this OpenAPI.NET object model. We'd like to curate that list of processors in this section of the readme. Converts standard .NET annotations ( /// comments ) emitted from your build (MSBuild.exe) into OpenAPI.NET document object. Converts the XML representation of the Entity Data Model (EDM) describing an OData Service into OpenAPI.NET document object. -

Faraday
Simple, but flexible HTTP client library, with support for backends
Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters (such as Net::HTTP) and embraces the concept of Rack middleware when processing the request/response cycle. You probably don't want to use Faraday directly in your project, as it will lack an actual client library to perform requests. Instead, you probably want to have a look at Awesome Faraday for a list of available adapters. The best starting point is the Faraday Website, with its introduction and explanation. This library aims to support and is tested against the currently officially supported Ruby implementations. This means that, even without a major release, we could add or drop support for Ruby versions, following their EOL. Currently that means we support Ruby 2.6+. You can also install the faraday_middleware extension gem to access a collection of useful Faraday middleware. -

Http4s
A minimal, idiomatic Scala interface for HTTP
Http4s is a minimal, idiomatic Scala interface for HTTP services. Http4s is Scala's answer to Ruby's Rack, Python's WSGI, Haskell's WAI, and Java's Servlets. http4s servers and clients share an immutable model of requests and responses. Standard headers are modeled as semantic types, and entity codecs are done by typeclass. The pure functional side of Scala is favored to promote composability and easy reasoning about your code. I/O is managed through cats-effect. http4s is built on FS2, a streaming library that provides for processing and emitting large payloads in constant space and implementing websockets. http4s cross-builds for Scala.js and Scala Native. Share code and deploy to browsers, Node.js, native executable binaries, and the JVM. -
21
Jimp
An image processing library written entirely in JavaScript for Node
An image processing library for Node written entirely in JavaScript, with zero native dependencies. If you're using this library with TypeScript the method of importing slightly differs from JavaScript. Instead of using require, you must import it with ES6 default import scheme. If you're using a web bundles (webpack, rollup, parcel) you can benefit from using the module build of jimp. Using the module build will allow your bundler to understand your code better and exclude things you aren't using. If you're using webpack you can set process.browser to true and your build of jimp will exclude certain parts, making it load faster. The static Jimp.read method takes the path to a file, URL, dimensions, a Jimp instance or a buffer and returns a Promise. In some cases, you need to pass additional parameters with an image's URL. -

Adblock FastOwnTracks Recorder
Store and access data published by OwnTracks apps
The OwnTracks Recorder is a lightweight program for storing and accessing location data published via MQTT (or HTTP) by the OwnTracks apps. It is a compiled program which is easy to install and operate even on low-end hardware, and it doesn't require an external database. There are two main components: the Recorder obtains data via MQTT subscribes or HTTP POST, stores the data in plain files and serve it via its built-in REST API, and the ocat command-line utility reads stored data in a variety of formats. We developed the Recorder as a one-stop solution to storing location data published by our OwnTracks apps (iOS and Android) and retrieving this data. Our previous offerings (m2s, o2s/Pista) also work of course, but we believe the Recorder is best suited to most environments. -
