golem-make-http-request-rust

Use the wstd::http Client, which is included by default in Golem Rust templates. Build a request with Request::get or Request::post, attach a body (Body::empty() for GET), and send it with Client::new().send(request).await.

No, reqwest, ureq, hyper, and surf do not work in Golem because they depend on native networking like tokio and OpenSSL, which are unavailable in WebAssembly. Use wstd::http or golem-wasi-http, which target the WASI HTTP interface.

wstd::http is a lightweight async client included by default in Golem Rust templates. golem-wasi-http offers a reqwest-style builder API with bearer auth, query params, multipart uploads, charset decoding, and manual streaming control over the request lifecycle.

Define a named retry policy keyed on status-code in golem.yaml, and the host transparently re-sends the request on matching 5xx responses. Alternatively, inspect the response status and return an Err, optionally wrapping the call in with_atomic_operation.

Golem agent endpoints deserialize non-binary bodies from a JSON object whose fields match method parameter names. Send Content-Type: application/json with a body like {"body": "value"} instead of raw text.
