Crate golem_wasi_http 

golem-wasi-http

An HTTP client library that uses WASI HTTP (WebAssembly System Interface) as its backend.

The library provides a convenient API for making HTTP requests from WASM components. It supports both async and synchronous operations, with optional support for JSON and multipart forms.

Originally started as a fork of the reqwest library but diverged significantly and dropped all the non WASI-HTTP backends.

Features

• Async and blocking Clients
• Plain bodies, JSON, form data, and multipart support
• Custom request/response body handling

Optional Features

The following are a list of [Cargo features][cargo-features] that can be enabled or disabled:

• async: Async client API using the wstd crate
• json: Provides serialization and deserialization for JSON bodies.
• multipart: Provides functionality for multipart forms.
