This repo shows how to implement a RESTful API in Rust with Actix Web and the MongoDB Rust Driver.
This REST API uses simple JWT authentication. Note that it does not actually integrate with Auth0!
You will need to have MongoDB installed and running on localhost:27017. If on macOS, for instance, follow MongoDB's installation instructions.
Issue a POST to the /login route to obtain a JWT bearer token.
% curl -v http://127.0.0.1:9000/login -X POST -d '{"email": "Joe User", "password": "secret"}' -H "Content-Type: application/json"
Note: Unnecessary use of -X or --request, POST is already inferred.

The JWT bearer token can now be specified to the protected routes such as /users.

{"data":[{ "_id": ObjectId("668e994c7eba267f28496f8a"), "firstname": "Joe", "lastname": "User", "email": "joe@example.org" },]}
The simple example has GET, POST, and DELETE routes in the main function.
The GET /users route searches MongoDB for all users and then returns a JSON string of the data.
// src/main.rs
...
async fn get_data_string(result: mongodb::error::Result<Document>) -> Result<web::Json<Document>, String> {
match result {
Ok(doc) => Ok(web::Json(doc)),
Err(e) => Err(format!("{}", e)),
}
}
async fn get_users() -> impl Responder {
let client_options = ClientOptions::parse("mongodb://localhost:27017").await.unwrap();
let client = Client::with_options(client_options).unwrap();
let collection = client.database("rust-users").collection::<Document>("users");
let mut cursor = collection.find(None, None).await.unwrap();
let mut data_result = "{\"data\":[".to_owned();
while let Some(result) = cursor.try_next().await.unwrap() {
match get_data_string(Ok(result)).await {
Ok(data) => {
let string_data = format!("{},", data.into_inner());
data_result.push_str(&string_data);
}
Err(e) => return HttpResponse::InternalServerError().body(e),
}
}
data_result.push_str("]}");
HttpResponse::Ok()
.content_type("application/json")
.body(data_result)
}
...The POST /users route takes JSON data and saves in the database. The data conforms to the User struct.
// src/main.rs
...
#[derive(Serialize, Deserialize)]
struct User {
firstname: String,
lastname: String,
email: String,
}
...
async fn new_user(info: web::Json<User>) -> impl Responder {
let client_options = ClientOptions::parse("mongodb://localhost:27017").await.unwrap();
let client = Client::with_options(client_options).unwrap();
let collection = client.database("rust-users").collection::<Document>("users");
let user = doc! {
"firstname": &info.firstname,
"lastname": &info.lastname,
"email": &info.email,
};
match collection.insert_one(user, None).await {
Ok(_) => HttpResponse::Ok().body("Item saved!"),
Err(e) => HttpResponse::InternalServerError().body(format!("{}", e)),
}
}
...The DELETE /users/:user_id takes an objectid as a parameter, decodes it into BSON, and deletes it from the database.
// src/main.rs
...
async fn delete_user(req: HttpRequest) -> impl Responder {
let client_options = ClientOptions::parse("mongodb://localhost:27017").await.unwrap();
let client = Client::with_options(client_options).unwrap();
let collection = client.database("rust-users").collection::<Document>("users");
let object_id = req.match_info().get("id").unwrap();
let id = ObjectId::parse_str(object_id).unwrap();
match collection.delete_one(doc! {"_id": id}, None).await {
Ok(_) => HttpResponse::Ok().body("Item deleted!"),
Err(e) => HttpResponse::InternalServerError().body(format!("{}", e)),
}
}
...Auth0 helps you to:
- Add authentication with multiple authentication sources, either social like Google, Facebook, Microsoft Account, LinkedIn, GitHub, Twitter, Box, Salesforce, amont others, or enterprise identity systems like Windows Azure AD, Google Apps, Active Directory, ADFS or any SAML Identity Provider.
- Add authentication through more traditional username/password databases.
- Add support for linking different user accounts with the same user.
- Support for generating signed Json Web Tokens to call your APIs and flow the user identity securely.
- Analytics of how, when and where users are logging in.
- Pull data from other sources and add it to the user profile, through JavaScript rules.
- Go to Auth0 and click Sign Up.
- Use Google, GitHub or Microsoft Account to login.
