我正在学习用rust写一个API来更新一些记录。我定义了一个rust（v1.69.0）rocket API如下：
#[macro_use] extern crate rocket;
use rocket::{serde::json::Json, response::content};
use rust_wheel::common::util::model_convert::box_rest_response;
use rocket::serde::Deserialize;
use rocket::serde::Serialize;
#[put("/test", data = "<request>")]
pub fn flush_render_result(
request: Json<RenderResultRequest>
) -> content::RawJson<String> {
let req = request;
return box_rest_response("ok");
}
#[launch]
fn rocket() -> _ {
rocket::build().mount("/", routes![flush_render_result])
}
#[derive(Debug, PartialEq, Eq, Deserialize, Serialize)]
#[allow(non_snake_case)]
pub struct RenderResultRequest {
pub gen_status: i32,
pub id: i64,
}这就是Cargo.toml：
[package]
name = "rust-learn"
version = "0.1.0"
edition = "2018"
[dependencies]
serde = { version = "1.0.64", features = ["derive"] }
serde_json = "1.0.64"
rocket = { version = "0.5.0-rc.2", features = ["json"]}
rust_wheel = { git = "https://github.com/jiangxiaoqiang/rust_wheel.git", branch = "diesel2.0" }这是Rocket.toml：
[release]
workers = 5
log_level = "normal"
keep_alive = 5
port = 11016
[debug]
port = 11016当我在macOS 13.2终端中使用命令请求API时：
> curl -X PUT http://127.0.0.1:11016/test -H "Content-Type: application/json" -H "x-access-token:1" -H "app-id:1" -H "user-id:1" -H "x-request-id:1" -H "device-id:1" -d "{
"id": 1,
"gen_status": 1
}"

<div role="main" align="center">

<p>The request could not be understood by the server due to malformed syntax.</p>

</div>
<div role="contentinfo" align="center">

📬 Routes:
>> (flush_render_result) PUT /test
📡 Fairings:

🛡️ Shield:

PUT /test application/json:

>> Data guard `Json < RenderResultRequest >` failed: Parse("{\n id: 1,\n gen_status: 1\n}", Error("key must be a string", line: 2, column: 5)).
>> Outcome: Failure
>> No 400 catcher registered. Using Rocket default.
>> Response succeeded.我试过删除空间，还是不行：
curl -X PUT http://127.0.0.1:8000/cv/gen/v1/result -H "Content-Type: application/json" -H "x-access-token:1" -H "app-id:1" -H "user-id:1" -H "x-request-id:1" -H "device-id:1" -d "{"id": 1,"gen_status": 1}"

您未能在curl调用中正确转义
"，因此shell使用了它们，导致有效负载为而不是有效的JSON
请注意键的引号中的差异。
要解决这个问题，你可以在json中使用转义引号（
\"）来调用curl，或者像这样使用不同的外引号：
