Also, a lot of work originally done on the proxy side was moved to client(service) side.The next significant feature is the WebSocket support.HTTP client for golang, Inspired by Javascript-axios Python-request. The v2 should bring some performance improvements because the serialization is done via protocol buffers. ![]() ![]() However for the purpose of bridging REST(HTTP) requests to NATS messaging platform, it’s enough to make it possible.Ĭurrently, the next version (v2) is under development. The first version (v1) of the nats-proxy framework implements only HTTP Request/Response proxying.īecause it started as some kind of proof of concept, the solution is not really optimized, all the work is done on the proxy side.Īlso, the serialization of structs is done by JSON encoder, which does not provide very fast serialization. The proxy receives the HTTP request and translates it into a struct, which contains all the information from original request (URL, header, body). Proxy basicsĪs the name of the project suggests the function of the library is very similar to basic HTTP proxy. So one of the many examples of how the system using a nats-proxy framework could look like is on the architecture below. Incoming requests must set the value of this header to one of the Proxys clientKeys to be authorized. But as it evolved, it started to grow into some kind of framework, that can be used for the creation of service API and seamless protocol bridging. The name of the HTTP header to use for client keys. The library was originally created for the purpose of migrating REST based architecture like this So the REST to NATS project uses this similarity between NATS and HTTP communication and tries to implement the bridge between HTTP(Websockets) and NATS in such way. For this purpose, the Publish/Subscribe model could be used. The asynchronous, let’s say real-time communication, can be represented by Websockets on HTTP side.The truth is that it is not really related to HTTP, but if we simplify it, at least the handshake is based on HTTP. An unauthenticated, remote attacker can exploit this, via a crafted Proxy header in an HTTP request, to redirect an applications internal HTTP traffic to. Model describes: each request sent via NATS contains reply subject, to which the reply is sent. ![]() The synchronous communication, represented by simple Request and Response of HTTP protocol, could be matched with the Request/Reply communication model of NATS. Why Because, TLS connection has nothing to do with proxy, TLS is available as a addon to an already existing TCP connection. HTTPĪs you can see, the NATS provides both synchronous and asynchronous communication between clients. By using Goproxy, a minimalist project, you can easily add Go module proxy support to any existing web service, you know that Goproxy.cn is built on it. The table below represents the matching of HTTP and NATS concepts and what do they provide. Self-hosted Go module proxy Your code is always yours, so we provide you with the coolest self-hosted Go module proxy building solution in the world. GO > HTTP > Setting-up-proxy-for-HTTP-client Next Page Setting up proxy for HTTP client Question: How to setup a HTTP client so that it uses a proxy in go lang Here is a go lang example that calls a HTTP GET using a proxy: Source: (example. To introduce the problem, we first compare the HTTP and NATS communication models. Beyond that, I believe that none have the same core simplicity that my requests library eventually achieved. Is the micro framework that provides a bridge between HTTP and NATS. Currently most people implement HTTPS proxies in Go with http. Two is hiding the underlying http.Client in such a way that it is difficult or impossible to replace or mock out. ![]()
