Rust Rocket MongoDB token-auth REST API boilerplate

In this repository, you can find backend Rust rocket mongodb rest-api boilerplate with token authorization.

#[get("/public/hello")]
pub async fn hello_world() -> Json<&'static str> {
  Json("Hello world")
}

Visiting localhost:8000/api/v1/public/hello, for example, will trigger the hello route resulting in the string Hello world being sent to the browser. In this example there is no authorization.

How to start

First you need to download this repository to your computer

Write this in your terminal:

git clone https://github.com/martyr00/Rust-rocket-mongoDB-token-auth-REST-API-boilerplate.git

After open the project in your IDE

You need to make your private.rs file as in the private.sample.rs:

pub const JWT_SECRET: &[u8] = b"<YOUR_JWT_SECRET_KEY>";
pub const REFRESH_JWT_SECRET: &'static str = b"<YOUR_REFRESH_JWT_SECRET_KEY>";
pub(crate) const URL_DB: &str = "mongodb+srv://<YOUR_LOGIN>:<YOUR_PASSWORD>@cluster0.d5yn0.mongodb.net/<YOUR_DB_NAME>";

JWT_SECRET and REFRESH_JWT_SECRET you need to come up with your own secret word to encrypt the tokens
For URL_DB you need registration your mongoDB acc here https://cloud.mongodb.com/

To run write this in your terminal:

cargo check && cargo run

Routes

/api/v1/registration (POST)
/api/v1/login (POST)
/api/v1/refresh (POST)
/api/v1/public/hello (GET)
/api/v1/hello (GET)
/api/v1/public/user (DELETE, PATCH)

Registration acc

Registration request:

login (must be unique && len login must be from 3 to 200 letter)
password (len password must be from 8 to 200 letter and password is hashed before being saved to the database.)
mail (must be unique and mail)
first_name (len must be from 2 to 150 letter and this field is optional)
last_name (len must be from 2 to 200 letter and this field is optional)

pub struct RegistrationRequest {
    pub login: String,
    pub password: String,

    pub mail: String,

    pub first_name: String,
    pub last_name: String,
}

Example registration request:

{
    "login": "test",
    "password": "12345678",
    "mail": "test@gmail.com",
    "first_name": "Test",
    "last_name": ""
}

Registration response

In response, the server will send 2 JWT tokens. The token is valid for 1 hour. Refresh token is valid for 7 days. token is needed to verify user authorization. With each private request, the token will be sent fronted to the headers in the authorization field.

If everything is correct:

pub struct Token {
    pub token: String,
    pub refresh_token: String,
}

Example:

{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiNjJiNGRhOTk4ZjgyMzc2YTk1MzM1MWIxIiwiZXhwIjoxNjU2MDIzMjA5fQ.aJFDZVyMBuNYh5EAArYYfzYCTnHHCQ7IHuZpKNCXHs0",
    "refresh_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiNjJiNGRhOTk4ZjgyMzc2YTk1MzM1MWIxIiwiZXhwIjoxNjU4NjExNjA5fQ.2_DjxtQxtsLsprvhBfYU8rKAoDfWMdshoPKDUqq6QZQ"
}

Possible error:

bad login -> Status 400 and string "Bad login" in json
already registered login -> Status 400 and string "Already registered by login" in json
bad password -> Status 400 and string "Bad password" in json
already registered password -> Status 400 and string "Already registered by password" in json
bad mail -> Status 400 and string "Bad mail" in json
already registered mail -> Status 400 and string "Already registered by mail" in json

Example error:

Status 400 Bad Request

{
    "cause": "Already registered by login"
}

Login acc

Login request:

login(The server checks 2 logins from the database and the request)
password(The server checks the encrypted password in the database with the password from the request)

pub struct LoginRequest {
  pub login: String,
  pub password: String,
}

Example:

{
    "login": "test",
    "password": "12345678"
}

Login response:

If everything is correct:

pub struct Token {
    pub token: String,
    pub refresh_token: String,
}

Example:

{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiNjJhM2I3Zjg4MTE1OWVkYWJmNTcwZjYwIiwiZXhwIjoxNjU2MDI0MDM1fQ.5Nu0lbN5X656JhuY8PrK1IJhWFVjHxKbh8CssKqHQqk",
    "refresh_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiNjJhM2I3Zjg4MTE1OWVkYWJmNTcwZjYwIiwiZXhwIjoxNjU4NjEyNDM1fQ.5OUiED1no-uizfYmq1xk6Z6XpX9TsbezDx8QxPSbyV0"
}

Possible error:

Bad request(In any case)

Example:

Status 400

{
    "cause": "Wrong request"
}

Refresh token

In this route, the frontend asks the server to refresh the token with a refresh token in json

Refresh token request

refresh token(specific user)

pub struct RefreshToken {
    pub(crate) refresh_token: String,
}

Example refresh token request:

{
    "refresh_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiNjJhM2I3Zjg4MTE1OWVkYWJmNTcwZjYwIiwiZXhwIjoxNjU3NDg5NDcyfQ.BcTanbs5lyT-Yv2ekf5-xl_NzEqpKsh5S59AEuZrmVQ"
}

Refresh token response

If everything is correct:

pub struct Token {
    pub token: String,
    pub refresh_token: String,
}

Example:

{
    "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiNjJhM2I3Zjg4MTE1OWVkYWJmNTcwZjYwIiwiZXhwIjoxNjU2MDI0MDM1fQ.5Nu0lbN5X656JhuY8PrK1IJhWFVjHxKbh8CssKqHQqk",
    "refresh_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiNjJhM2I3Zjg4MTE1OWVkYWJmNTcwZjYwIiwiZXhwIjoxNjU4NjEyNDM1fQ.5OUiED1no-uizfYmq1xk6Z6XpX9TsbezDx8QxPSbyV0"
}

Possible error:

Unauthorized

Example:

Status 400

{
    "cause": "Unauthorized"
}

Public hello

This is the only route without authorization. Therefore there is no request in this route.

Rust code:

#[get("/public/hello")]
pub async fn hello_world() -> Json<&'static str> {
  Json("Hello world")
}

Response in json:

{
  "Hello world"
}

Private hello

In this route, the server checks in the headers token if the token is valid then the server executes the program.

Private hello request:

From headers:

authorization Bearer (TOKEN)

Example:

authorization Bearer eyJ0eXAiOiJKV1QiLCJhbGci....

Private hello response

the response will be a greeting with the user. If the database contains his first name and surname, then the program will greet you by the first name and surname; if not, the program will greet you by login

If everything is correct:

pub struct HelloNameResponse {
    pub(crate) greetings: String,
}

Example:

{
    "greetings": "Hello test"
}

Possible error:

Unauthorized

Example:

Status 401

{
"cause": "Unauthorized"
}
