1. 查看苹果官方文档

2. 创建AppleUtil工具类

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import com.auth0.jwk.Jwk;
import io.jsonwebtoken.*;

import org.springframework.web.client.RestTemplate;

import java.security.PublicKey;

public class AppleUtil {

    private static final String APPLE_AUTH_URL = "https://appleid.apple.com/auth/keys";
    private static final String APPLE_ID_URL = "https://appleid.apple.com";

    private static JSONArray getAuthKeys() throws Exception {
        RestTemplate restTemplate = new RestTemplate();
        JSONObject json = restTemplate.getForObject(APPLE_AUTH_URL, JSONObject.class);
        JSONArray arr = json.getJSONArray("keys");
        return arr;
    }

    public static Boolean verify(String jwt) throws Exception {
        JSONArray arr = getAuthKeys();
        if (arr == null) {
            return false;
        }
        JSONObject authKey = null;

            return true;
        } else {

            authKey = JSONObject.parseObject(arr.getString(1));
            return verifyExc(jwt, authKey);
        }

    }

        PublicKey publicKey = jwa.getPublicKey();
        String aud = "";
        String sub = "";
        if (jwt.split("\.").length > 1) {
            String claim = new String(Base64.decodeBase64(jwt.split("\.")[1]));
            aud = JSONObject.parseObject(claim).get("aud").toString();
            sub = JSONObject.parseObject(claim).get("sub").toString();
        }
        JwtParser jwtParser = Jwts.parser().setSigningKey(publicKey);
        jwtParser.requireIssuer(APPLE_ID_URL);
        jwtParser.requireAudience(aud);
        jwtParser.requireSubject(sub);
        try {
            Jws<Claims> claim = jwtParser.parseClaimsJws(jwt);
            if (claim != null && claim.getBody().containsKey("auth_time")) {
                return true;
            }
            return false;
        } catch (ExpiredJwtException e) {
            return false;
        } catch (Exception e) {
            return false;
        }
    }


    /**

     *

    public static JSONObject parserIdentityToken(String identityToken) {
        String[] arr = identityToken.split("\.");
        Base64 base64 = new Base64();
        String decode = new String(base64.decodeBase64(arr[1]));
        String substring = decode.substring(0, decode.indexOf("}") + 1);
        JSONObject jsonObject = JSON.parseObject(substring);
        return jsonObject;
    }

}

3. 具体处理

	public void appleLogin(String identityToken){
		if (!AppleUtil.verify(identityToken)) {
            return RespBean.error("authorization verification failed");
        }
        //对identityToken解码
        JSONObject appleResult = AppleUtil.parserIdentityToken(identityToken);
        if (appleResult == null) {
            return RespBean.error("authorization decoding failed");
        } else {
        	//业务逻辑处理
        }
	}
