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. -

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. -

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. -

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. -

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. -

http4k
The Functional toolkit for Kotlin HTTP applications
http4k is a lightweight but fully-featured HTTP toolkit written in pure Kotlin that enables the serving and consuming of HTTP services in a functional and consistent way. http4k applications are just Kotlin functions. http4k consists of a lightweight core library, http4k-core, providing a base HTTP implementation and Server/Client implementations based on the JDK classes. Further servers, clients, serverless, templating, websockets capabilities are then implemented in add-on modules. http4k apps can be simply mounted into a running Server, Serverless platform, or compiled to GraalVM and run as a super-lightweight binary. Apart the from Kotlin StdLib, http4k-core module has ZERO dependencies and weighs in at ~1mb. Add-on modules only have dependencies required for specific implementation. -

ky
JavaScript HTTP client based on the browser Fetch API
Ky targets modern browsers and Deno. For older browsers, you will need to transpile and use a fetch polyfill and globalThis polyfill. For Node.js, check out Got. For isomorphic needs (like SSR), check out ky-universal. It's just a tiny file with no dependencies. Internally, the standard methods (GET, POST, PUT, PATCH, HEAD and DELETE) are uppercased in order to avoid server errors due to case sensitivity. Search parameters to include in the request URL. Setting this will override all existing search parameters in the input URL. After prefixUrl and input are joined, the result is resolved against the base URL of the page (if any). The hook can return a Request to replace the outgoing request, or return a Response to completely avoid making an HTTP request. This can be used to mock a request, check an internal cache, etc. An important consideration when returning a request or response from this hook is that any remaining beforeRequest hooks will be skipped. -

plow
A high-performance HTTP benchmarking tool
Plow is an HTTP(S) benchmarking tool, written in Golang. It uses excellent fast HTTP instead of Go's default net/http due to its lightning-fast performance. Plow runs at specified connections (option -c) concurrently and real-time records summary statistics, histogram of execution time and calculates percentiles to display on Web UI and terminal. It can run for a set duration( option -d), for a fixed number of requests(option -n), or until Ctrl-C is interrupted. The implementation of real-time computing Histograms and Quantiles using stream-based algorithms inspired by Prometheus with low memory and CPU bounds. so it's almost no additional performance overhead for benchmarking. -

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. -

Laravel Webhook Server
Send webhooks from Laravel apps
A webhook is a mechanism where an application can notify another application that something has happened. Technically, the application sends an HTTP request to that other application. In this blog post, I'd like to introduce you to two packages that we recently released. The first is laravel-webhook-server, which allows you to send webhook requests. The second one is laravel-webhook-client, which makes it easy to receive those webhook request. Webhooks are very useful when a system wants to be notified as soon as something happens in another system. Let's make that a bit less abstract and take a look at a real-world example. laravel-webhook-server allows you to configure and send webhooks in a Laravel app easily. So you'll install this into the app that wants to notify other apps that something has happened. The package has support for signing calls, retrying calls, and backoff strategies. -

Promxy
An aggregating proxy to enable HA prometheus
Promxy is a prometheus proxy that makes many shards of prometheus appear as a single API endpoint to the user. This significantly simplifies operations and use of prometheus at scale (when you have more than one prometheus host). Promxy delivers this unified access endpoint without requiring any sidecars, custom-builds, or other changes to your prometheus infrastructure. Prometheus itself provides no real HA/clustering support. As such the best-practice is to run multiple (e.g N) hosts with the same config. Similarly prometheus has no real built-in query federation, which means that you end up with N sources in grafana which is (1) confusing to grafana users and (2) has no support for aggregation across the sources. Promxy enables an HA prometheus setup by "merging" the data from the duplicate hosts (so if there is a gap in one, promxy will fill with the other). In addition Promxy provides a single datasource for all promql queries. -

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. -

EGO
A simple and component-based microservice kit for go
EGO is a microservice-oriented governance framework implemented by golang, which integrates various engineering practices. Through the component-based design pattern, it is guaranteed that the business development can use various components in a unified way. For us engineers to improve component proficiency, we must first read a lot of open-source component documentation and code, and then insist on using it for a long time in order to form muscle memory and improve our speed of doing business. And the time and energy invested in all of this is enormous. To reduce this input cost and allow more developers to better use excellent open source components, EGO's approach is to standardize all open source components, encapsulate them, and unify various behaviors. -

HTTP Shortcuts for Android
Android app to create home screen shortcuts
A simple Android app that allows you to create shortcuts that can be placed on your home screen. Each shortcut, when clicked, triggers an HTTP request, with the possibility to process and display the response in various ways. Run arbitrary JavaScript before & after execution, which allows for lots of customization with features such as compute values such as timestamps, random numbers, UUIDs, hashes, HMACs, base64, etc. Parse JSON or XML and extract data from them. Show toast message or message dialogs. Vibrate or play notification sounds. Trigger other shortcuts to chain multiple HTTP requests. Interact with other devices and services by sending TCP or UDP packets, MQTT messages or using Wake-on-LAN.
