如何在Rocket中返回外部API查询到的objects数组

#[macro_use] extern crate rocket;

use rocket::http::Status;
use rocket::serde::json::json;
use rocket::serde::Serialize;
use reqwest::Error as ReqwestError;

#[derive(Serialize)]
struct Object {
    // 定义objects数组中的对象结构
    // 根据实际情况进行定义
    // 示例中假设对象有一个名为"name"的属性
    name: String,
}

#[get("/objects")]
async fn get_objects() -> Result<rocket::Response<'static>, Status> {
    // 发送GET请求到外部API
    let response = reqwest::get("https://api.example.com/objects").await;

    match response {
        Ok(response) => {
            // 检查响应状态码
            if response.status().is_success() {
                // 解析响应体中的JSON数据
                let objects: Vec<Object> = response.json().await.unwrap();

                // 将objects数组转换为JSON格式
                let json_response = json!({ "objects": objects });

                // 构建Rocket的HTTP响应
                let response = rocket::Response::build()
                    .header(rocket::http::ContentType::JSON)
                    .sized_body(std::io::Cursor::new(json_response.to_string()))
                    .finalize();

                Ok(response)
            } else {
                Err(Status::InternalServerError)
            }
        }
        Err(_) => Err(Status::InternalServerError),
    }
}

#[launch]
fn rocket() -> _ {
    rocket::build().mount("/", routes![get_objects])
}
