wasmCloud Extras Actor接口

此Crate为wasmCloud Actor提供对额外能力提供者的接口。每个wasmCloud宿主运行时都自带内置的额外提供者。然而，使用此提供者的Actor仍需要使用wasmcloud:extras能力合同ID进行签名。

以下函数在Host接口上得到支持

• request_guid
• request_sequence
• request_random

示例

extern crate wapc_guest as guest;
use guest::prelude::*;
use wasmcloud_actor_core as actor;
use wasmcloud_actor_extras as extras;
use wasmcloud_actor_http_server as http;
use serde_json::json;
use log::{error, info};

#[actor::init]
pub fn init() {
    http::Handlers::register_handle_request(generate_guid);
}

/// Generate a Guid and return it in a JSON envelope
fn generate_guid(_req: http::Request) -> HandlerResult<http::Response> {
  let guid = get_guid()?      // Replace this with `extras::default().request_guid()?`
                .unwrap_or("unknown-guid".to_string());

  let result = json!({"guid": guid });
  Ok(http::Response::json(&result, 200, "OK"))

}
