    Faraday

    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.

    Interactsh

    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.

    Martian Proxy

    Martian Proxy

    Martian is a library for building custom HTTP/S proxies

    Martian Proxy is a programmable HTTP proxy designed to be used for testing. Martian is a great tool to use if you want to verify that all (or some subset) of requests are secure. Mock external services at the network layer. Inject headers, modify cookies or perform other mutations of HTTP requests and responses. Verify that pingbacks happen when you think they should. Unwrap encrypted traffic (requires install of CA certificate in browser) By taking advantage of Go cross-compilation, Martian can be deployed anywhere that Go can target. Martian Proxy added support for Go modules since v3.0.0. If you use a Go version that does not support modules, this will break you. The latest version without Go modules support was tagged v2.1.0. For logging of requests and responses a logging modifier is available or HAR logs are available if the -har flag is used. Once Martian is running, you need to configure its behavior.

    HTTP server mocking and expectations library for Node.js

    HTTP server mocking and expectations library for Node.js. Nock can be used to test modules that perform HTTP requests in isolation. For instance, if a module performs HTTP requests to a CouchDB server or makes HTTP requests to the Amazon API, you can test that module in isolation. Nock works by overriding Node's http.request function. Also, it overrides http.ClientRequest too to cover for modules that use it directly.
