casdoor-react-sdk
It can help you quickly build a silent sign-in application based on Casdoor.
We have an implemented example: casdoor-spring-security-react-example.
To use this sdk just follow the steps below.
Installation
#NPM
npm i casdoor-react-sdk
#YARN
yarn add casdoor-react-sdk
Use in React
Let's take a look at the following example of a silent sign-in.
First, you need to initialize the Casdoor SDK.
import Sdk from "casdoor-js-sdk";
export const ServerUrl = "http://localhost:7023";
const sdkConfig = {
serverUrl: "http://localhost:8000",
clientId: "d79fd3c4e09a309fb3f5123",
appName: "application_hnpzib",
organizationName: "organization_4emn5k",
redirectPath: "/callback",
signinPath: "/api/signin",
};
export const CasdoorSDK = new Sdk(sdkConfig);
Then, intercept the /callback
path in your application, the AuthCallback
component will help you automatically handle the logic of interacting with the server, you just need to make sure that your server ServerUrl
implements the ${ServerUrl}/api/signin
api, and takes two parameters code
and state
, and returns token
.
Note: Here you need to implement the
saveTokenFromResponse
andisGetTokenSuccessful
functions.
isGetTokenSuccessful
:you need to judge from the response data whether the request is processed successfully by the server.saveTokenFromResponse
:when your${ServerUrl}/api/signin
api successfully returns the token, you need to save the token.
import { Route, BrowserRouter, Routes } from "react-router-dom";
import { AuthCallback } from "casdoor-react-sdk";
import * as Setting from "./Setting";
import HomePage from "./HomePage";
function App() {
const authCallback = (
<AuthCallback
sdk={Setting.CasdoorSDK}
serverUrl={Setting.ServerUrl}
saveTokenFromResponse={(res) => {
// @ts-ignore
// save token
localStorage.setItem("token", res.data.accessToken);
}}
isGetTokenSuccessful={(res) => {
// @ts-ignore
// according to the data returned by the server,
// determine whether the `token` is successfully obtained through `code` and `state`.
return res.success === true;
}}
/>
);
return (
<BrowserRouter>
<Routes>
<Route path="/callback" element={authCallback} />
<Route path="/" element={<HomePage />} />
</Routes>
</BrowserRouter>
);
}
export default App;
In your HomePage
to determine whether you need to log in silently, if you need to log in silently, return the SilentSignin
component, it will help you initiate a login request, and after the login is successful, it will call the handleReceivedSilentSigninSuccessEvent
function, and when the login fails, it will also Call the handleReceivedSilentSigninFailureEvent
function.
import * as Setting from "./Setting";
import { SilentSignin, isSilentSigninRequired } from "casdoor-react-sdk";
function HomePage() {
const isLoggedIn = () => {
return localStorage.getItem("token") !== null;
};
if (isSilentSigninRequired()) {
// if the `silentSignin` parameter exists, perform silent login processing
return (
<SilentSignin
sdk={Setting.CasdoorSDK}
isLoggedIn={isLoggedIn}
handleReceivedSilentSigninSuccessEvent={() => {
// jump to the home page here and clear silentSignin parameter
window.location.href = "/";
}}
handleReceivedSilentSigninFailureEvent={() => {
// prompt the user to log in failed here
alert("login failed");
}}
/>
);
}
const renderContent = () => {
if (isLoggedIn()) {
return <div>Hello!</div>;
} else {
return <div>you are not logged in</div>;
}
};
return renderContent();
}
export default HomePage;
