This is Casdoor's SDK for Rust, which will allow you to easily connect your application to the Casdoor authentication system without having to implement it from scratch.
Casdoor SDK is very simple to use. We will show you the steps below.
``` [dependencies] casdoor-rust-sdk = "0.1"
//in your app [macrouse] extern crate casdoorrust_sdk; ```
Initialization requires 6 parameters, which are all string type:
| Name (in order) | Must | Description |
| --------------- | ---- | ------------------------------------------------------------------- |
| endpoint | Yes | Casdoor Server Url, such as http://localhost:8000 |
| clientid | Yes | Application.clientid |
| clientsecret | Yes | Application.clientsecret |
| certificate | Yes | Same as your Application Certificate |
| orgname | Yes | Application.organization |
| frontendpoint | No | Casdoor web endpoint, default is endpoint.replace(":8000", ":7001") |
rust
//anything implemented "ToString" trait can be used by this macro
let app = newsdk!(endpoint, client_id, client_secret, certificate, org_name);
After casdoor verification passed, it will be redirected to your application with code and state, like http://forum.casbin.org?code=xxx&state=yyyy.
Your web application can get the code,state and call GetOAuthToken(code, state), then parse out jwt token.
Hints:
redirect_uri is the URL that your APP is configured to
listen to the response from Casdoor. For example, if your redirect_uri is https://forum.casbin.com/callback, then Casdoor will send a request to this URL along with two parameters code and state, which will be used in later steps for authentication.
state is usually your Application's name, you can find it under the Applications tab in Casdoor, and the leftmost Name column gives each application's name.
Of course you want your APP to be able to send the URL. For example you should have something like a button, and it carries this URL. So when you click the button, you should be redirected to Casdoor for verification. For now you are typing it in the browser simply for testing.
Result<_, Box<dyn std::error::Error>>, as there are mutiple kinds of error possible.The general process is as follows:
```rust
//config will generate a NetWorkConfig struct, default response type is "code", and default scope is "read"
let config = &networkconfig!(callback, state)
let link = app.getauthlink(&config)?;
//and the code will be sent to callback address
let code = (your method to get code);
let accesstoken = app.getoauthtoken(&code)?;
//the claims returns a HashMap
```
The sdk support basic user operations, like:
get_user_by_name(name), get one user by user name.get_users(), get all users.add_user(User), write user to database.update_user(User), update user infodelete_user(User), delete user
