是的，您是对的，可以很好地将 facebook 登录与 react 组件集成在一起。
示例登录组件可以是这样的 -
import React from 'react';
class LoginComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
};
}
loadFbLoginApi() {
window.fbAsyncInit = function() {
FB.init({
appId : FB_APP_ID,
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : 'v2.5' // use version 2.1
});
};
console.log("Loading fb api");
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
}
componentDidMount() {
this.loadFbLoginApi();
}
testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Successful login for: ' + response.name);
document.getElementById('status').innerHTML =
'Thanks for logging in, ' + response.name + '!';
});
}
statusChangeCallback(response) {
console.log('statusChangeCallback');
console.log(response);
if (response.status === 'connected') {
this.testAPI();
} else if (response.status === 'not_authorized') {
console.log("Please log into this app.");
} else {
console.log("Please log into this facebook.");
}
}
checkLoginState() {
FB.getLoginStatus(function(response) {
this.statusChangeCallback(response);
}.bind(this));
}
handleFBLogin() {
FB.login(this.checkLoginState());
}
render() {
return (
<div>
<MyButton
classNames = "btn-facebook"
id = "btn-social-login"
whenClicked = {this.handleFBLogin}
>
<span className="fa fa-facebook"></span> Sign in with Facebook
</MyButton>
</div>
);
}
}
export default LoginComponent;
当收到的响应状态已连接时，这意味着用户通过 Facebook 登录，您可以在组件上设置状态以反映这一点。例如
response.status === 'connected'
this.setState({userLoggedIn:true});
我MyButton在 React 中使用了一个自定义按钮组件 ( )，您可以很容易地创建它。
