java后端-海外登录(谷歌/FaceBook)

前言

        由于最近公司的项目要在海外运行,因此需要对接海外的登录,目前就是谷歌和facebook两种,后面支付也是需要的,后续再进行书写

谷歌登录

        这个相对比较容易,而且只提供给安卓即可,废话就不多说了,直接贴解决方案

引入maven依赖

<dependency>
    <groupId>com.google.api-client</groupId>
    <artifactId>google-api-client</artifactId>
    <version>1.35.2</version>
</dependency>
<dependency>

工具类

@Slf4j
public class IdTokenVerifier {//安卓信息private static final String CLIENT_ID = Constants.GOOGLE_APPLE_ID; // 替换为你的 Android 客户端 IDpublic static GoogleIdToken.Payload verifyToken(String idTokenString) throws GeneralSecurityException, IOException {NetHttpTransport transport = new NetHttpTransport();GsonFactory jsonFactory = new GsonFactory();GoogleIdTokenVerifier verifier = new GoogleIdTokenVerifier.Builder(transport, jsonFactory).setAudience(Collections.singletonList(CLIENT_ID)).build();GoogleIdToken idToken = verifier.verify(idTokenString);if (idToken != null) {log.info("verifyToken-返回的数据为{}", JsonUtils.Object2Json(idToken));return idToken.getPayload();} else {// 无效的 ID tokenlog.info("verifyToken-返回的数据为null");return null;}}public static boolean checkNonce(String nonce, GoogleIdToken.Payload payload) {if(payload == null) {return false;}Object object = payload.get("nonce");if(object == null) {return false;}String requestNonce = (String) object;boolean equals = Objects.equals(nonce, requestNonce);log.info("checkNonce-检验结果为{}", equals);return equals;}public static void main(String[] args) throws GeneralSecurityException, IOException {// 示例用法：String receivedIdToken = "eyJfN5g"; // 替换为实际接收到的 idTokenGoogleIdToken.Payload payload = verifyToken(receivedIdToken);
//        GoogleIdToken.Payload payload = (GoogleIdToken.Payload) JsonUtils.string2Object(payloadString, GoogleIdToken.Payload.class);System.out.println(JsonUtils.Object2Json(payload));if (payload != null) {String userId = payload.getSubject();String email = payload.getEmail();boolean emailVerified = Boolean.valueOf(payload.getEmailVerified());String name = (String) payload.get("name");String pictureUrl = (String) payload.get("picture");String givenName = (String) payload.get("given_name");String familyName = (String) payload.get("family_name");String locale = (String) payload.get("locale");System.out.println("User ID: " + userId);System.out.println("Email: " + email);System.out.println("Email Verified: " + emailVerified);System.out.println("Name: " + name);System.out.println("Picture URL: " + pictureUrl);System.out.println("Given Name: " + givenName);System.out.println("Family Name: " + familyName);System.out.println("Locale: " + locale);} else {System.out.println("Invalid ID token.");}}

只需要替换CLIENT_ID 为安卓的id,token也是安卓传给你的,就可以了,是不是很简单?

FaceBook登录

        这个其实也不复杂,主要是IOS有两种情况,老版本的方式跟安卓的方式是一样的,下面先说老的方式

IOS旧版/安卓

参考文章:   第三方登录（Facebook） java验证-CSDN博客   可行,但是有乱码问题,而且要自己写,麻烦点,没使用

我用的是工具包,也不复杂, 还是直接说做法

引入maven依赖

<dependency>
        <groupId>com.restfb</groupId>
        <artifactId>restfb</artifactId>
        <version>2024.11.0</version>
</dependency>

工具类

 public static void main(String[] args) throws Exception{token = "EAAVMz9Vc1BgBO8iE8yMgNza4ZCdnBDqZCMJRoGHJaykZAOIwLetZAluFdUEng31WUexZA16LpXQ2YWEYY2dj6TTPnv7Cq8DjXKANAZAy1WCpntLeykZCqnSy0Cy7S4ZCASVZA1cAVIlaGtw7mhV0NCvi0pKiTlej4C9fYbZA0yAlZBee999ZCZBa2Uf5dB12ZAG2jcKfmJg6gZDZD";
//                checkLoginWithToken(token);DefaultFacebookClient defaultFacebookClient = new DefaultFacebookClient(token, Version.VERSION_11_0);User re = defaultFacebookClient.fetchObject("me.permissions ", User.class, Parameter.with("fields", Parameter.with("fields", "id,cover,email,gender")));System.out.println(re.getName());System.out.println(re.getEmail());System.out.println(re.getFirstName());System.out.println(re.getBirthday());}

注: 其实就是两句话,底层都封装好了,

Parameter.with("fields", "id,cover,email,gender") 这个要输入一些，需要哪些就指定哪些

IOS新版

这个目前还不知道，到时确定了再回来更新咯
