Dependencies

Most of these examples use these dependencies:

[dependencies]
hyper = { version = "0.14", features = ["full"] }
tokio = { version = "1", features = ["full"] }
pretty_env_logger = "0.4"

Getting Started

Clients

• client - A simple CLI http client that request the url passed in parameters and outputs the response content and details to the stdout, reading content chunk-by-chunk.

• client_json - A simple program that GETs some json, reads the body asynchronously, parses it with serde and outputs the result.

Servers

• hello - A simple server that returns "Hello World!".

• echo - An echo server that copies POST request's content to the response content.

Going Further

• gateway - A server gateway (reverse proxy) that proxies to the hello service above.

• http_proxy - A simple HTTP(S) proxy that handle and upgrade CONNECT requests and then proxy data between client and remote server.

• multi_server - A server that listens to two different ports, a different Service per port.

• params - A webserver that accept a form, with a name and a number, checks the parameters are presents and validates the input.

• send_file - A server that sends back content of files using tokio-util to read the files asynchronously.

• service_struct_impl - A struct that manually implements the Service trait and uses a shared counter across requests.

• single_threaded - A server only running on 1 thread, so it can make use of !Send app state (like an Rc counter).

• state - A webserver showing basic state sharing among requests. A counter is shared, incremented for every request, and every response is sent the last count.

• upgrades - A server and client demonstrating how to do HTTP upgrades (such as WebSockets).

• web_api - A server consisting in a service that returns incoming POST request's content in the response in uppercase and a service that calls the first service and includes the first service response in its own response.
