我试图为我的火箭应用程序的3条路线写一些单元测试。到目前为止，get index函数工作正常，但两个post请求不工作
我越来越困惑，因为我一直得到一个404请求，我真的不知道为什么
tests.rs:

use super::rocket;
use rocket::local::blocking::Client;
use rocket::http::Status;
use rocket::uri;

#[test]
fn index() {
    let client = Client::tracked(rocket()).expect("valid rocket instance");
    let response = client.get(uri!(super::index)).dispatch();
    assert_eq!(response.status(), Status::Ok);

}

#[test]
fn add() {
    let client = Client::tracked(rocket()).expect("valid rocket instance");
    let response = client.post(uri!(super::add))
        .body("note=This is a test")
        .dispatch();
    assert_eq!(response.status(), Status::Ok);
}

#[test]
fn delete() {
    let client = Client::tracked(rocket()).expect("valid rocket instance");
    let response = client.post(uri!(super::delete))
        .body("noteid=1")
        .dispatch();
    assert_eq!(response.status(), Status::Ok);
}

main.rs代码省略空间的原因）：

任何帮助都会很好：）
