火箭无法解析 JSON

Question

我在尝试使用 rocket 解析 JSON 时遇到错误。这是我的代码：

extern crate serde;
use rocket::serde::{json::Json, Deserialize};
use serde::Serialize;
#[macro_use]
extern crate rocket;
mod eth;
mod rocket_test;

#[launch]
fn rocket() -> _ {
    rocket::build().mount("/task", routes![body])
}
#[derive(Serialize, Deserialize)]
struct Message2 {
    id: usize,
}

#[post("/", format = "json", data = "<message>")]
async fn body(message: Json<Message2>) -> &'static str {
    "Fine"
}

这是我的 toml 文件：

[dependencies]
serde = {version = "1.0", features = ["derive"]}
serde_derive = "1.0"
serde_json = "1.0"
tester = "0.9.0"
tokio = {version = "1", features = ["full"]}

[dependencies.rocket]
features = ["json"]
version = "0.5.0-rc.1"

我遇到了这个错误

thread 'rocket-worker-thread' panicked at 'assertion failed: `(left == right)`
  left: `0x28f12470657`,
 right: `0x28f12470640`', C:\Users\gadum\.cargo\registry\src\github.com-1ecc6299db9ec823\tokio-1.16.0\src\io\util\take.rs:93:9

和JSON解析的例子一样。但我不知道出了什么问题。我正在用 VSCode Rest 客户端发送请求，就像这样

POST http://127.0.0.1:8000/task
content-type: application/json

{
    "id": 10
}

tokio 的 1.16.0 版本似乎有错误：https://github.com/tokio-rs/tokio/issues/4435

执行 cargo update 它应该将您的依赖项更新为 1.16.1。
