wasmCloud HTTP Client Actor Interface
This crate provides wasmCloud actors with an interface to the HTTP client capability provider. Actors using this
interface must have the claim wasmcloud:httpclient
in order to have permission to make outbound HTTP requests,
and they must have an active, configured binding to an HTTP Client capability provider.
wasmCloud actors without this permission and capability binding will be unable to make outbound HTTP requests.
Example:
use wapc_guest::HandlerResult;
extern crate wasmcloud_actor_http_server as httpserver;
extern crate wasmcloud_actor_http_client as httpclient;
extern crate wasmcloud_actor_core as actor;
const API_URL: &str = "https://wasmcloudapi.cloud.io/proxy";
#[actor::init]
pub fn init() {
httpserver::Handlers::register_handle_request(get_proxy);
}
/// This function proxys an inbound HTTP request to an external server
fn get_proxy(msg: httpserver::Request) -> HandlerResult<httpserver::Response> {
// Form client request from server request
if msg.method == "GET".to_string() {
// Replace `request` with `httpclient::default().request`
let res = request(msg.method, API_URL.to_string(), msg.header, vec![])?;
// Form server response
Ok(httpserver::Response {
status_code: res.status_code,
status: res.status,
header: res.header,
body: res.body,
})
} else {
Ok(httpserver::Response::internal_server_error("Only GET requests can be proxied with this actor"))
}
}
