我在 rocket_cors 方法上遇到 Cargo 运行错误

Question

我正在尝试让我的 Rust Rocket 应用程序通过 cargo 运行

use rocket::http::Method;

fn make_cors() -> Cors {
  let allowed_origins = AllowedOrigins::some_exact(&[ // 4.
    "http://localhost:3000",
    "http://127.0.0.1:3000",
    "http://localhost:8000",
    "http://0.0.0.0:8000",
  ]);
  CorsOptions { // 5.
    allowed_origins,
    allowed_methods: vec![Method::Get].into_iter().map(From::from).collect(), // 1.
    allowed_headers: AllowedHeaders::some(&[
      "Authorization",
      "Accept",
      "Access-Control-Allow-Origin", // 6.
    ]),
    allow_credentials: true,
    ..Default::default()
  }.to_cors().expect("error while building CORS")
}

以下错误困扰着我：

the trait bound `rocket_cors::Method: std::convert::From<rocket::http::Method>` is not satisfied
the trait `std::convert::From<rocket::http::Method>` is not implemented for `rocket_cors::Method`

编辑：

固定为 rocket_cors::Method

现在出现以下错误：

  no associated item named `Get` found for struct `rocket_cors::Method` in the current scope
  --> src/main.rs:24:35
   |
24 |     allowed_methods: vec![Method::Get].into_iter().map(From::from).collect(), // 1.
   |                                   ^^^ associated item not found in `rocket_cors::Method`

Answer 1

你应该使用 Method wrapped by the rocket_cors，而不是 rocket 本身的那个，因为根据 rocket_cors 所说

A wrapper type around rocket::http::Method to support serialization and deserialization.

所以他们不一样。
