httpreqwasi

Simple and lightweight HTTP client for the low level wasmedgewasisocket library. It is to be compiled into WebAssembly bytecode targets and runs in the WasmEdge Runtime as a lightweight and secure alternative to natively compiled apps in Linux container.

This project is forked and derived from the http_req project created by jayjamesjay.

Example

Basic GET request in HTTPS

```rust use http_req::request;

fn main() { let mut writer = Vec::new(); //container for body of a response let res = request::get("https://httpbin.org/get?msg=WasmEdge", &mut writer).unwrap();

println!("Status: {} {}", res.status_code(), res.reason());
println!("Headers {}", res.headers());
println!("{}", String::from_utf8_lossy(&writer));

} ```

How to use:

toml [dependencies] http_req_wasi = "0.10"

Build and run

Install WasmEdge and then install the HTTPS plugin as follows.

```bash

Download and extract the plugin

wget https://github.com/WasmEdge/WasmEdge/releases/download/0.11.1/WasmEdge-plugin-wasmedgehttpsreq-0.11.1-manylinux2014x8664.tar.gz tar -xzf WasmEdge-plugin-wasmedgehttpsreq-0.11.1-manylinux2014x8664.tar.gz

Install the plugin if your wasmedge is installed in ~/.wasmedge

cp libwasmedgePluginHttpsReq.so ~/.wasmedge/plugin/

Install the plugin if your wasmedge is installed in /usr/local

cp libwasmedgePluginHttpsReq.so /usr/local/lib/wasmedge/ ```

Build the GET HTTPS example.

bash cargo wasi build --release --example get_https

Run the example.

```bash wasmedge target/wasm32-wasi/release/examples/get_https.wasm
