我这里使用的袤博的一键登录，其他类型的在之后会慢慢加入

袤博的一键登录，[http://wiki.mob.com/][http_wiki.mob.com]

业务代码调用

@PostMapping("/regAndLogin")
        @ApiOperation(value = "一键登录注册 v2")
        public void regAndLogin(@RequestBody LoginOneRequest loginOneRequest) throws Exception {
            loginOneRequest.setUserPhone(OneLoginUtils.getPhoneNumber(loginOneRequest.getMbToken(), loginOneRequest.getOpToken(), loginOneRequest.getOperator()));
     
        }

工具类 OneLoginUtils  代码可以自己优化

public class OneLoginUtils {
        private static String appkey = "*******";
        private static String appSecret = "*****";
        private static String authHost = "http://identify.verify.mob.com/";
        private static String url = authHost + "auth/auth/sdkClientFreeLogin";
    
        public static String getPhoneNumber(String mbToken,String opToken, String operator) throws Exception {
            HashMap<String, Object> request = new HashMap<>();
            request.put("appkey", appkey);
            request.put("token", mbToken);
            request.put("opToken",opToken);
            request.put("operator", operator);
            request.put("timestamp", System.currentTimeMillis());
            request.put("sign", SignUtil.getSign(request, appSecret));
            String response = Auth.postRequestNoSecurity(url, null, request);
            JSONObject jsonObject = JSONObject.parseObject(response);
            if (200 == jsonObject.getInteger("status")) {
                String res = jsonObject.getString("res");
                byte[] decode = DES.decode(Base64Utils.decode(res.getBytes()), appSecret.getBytes());
                jsonObject.put("res", JSONObject.parseObject(new String(decode)));
            }
    
            JSONObject jsonObject1 = JSON.parseObject(jsonObject.toString());
            String data = jsonObject1.getString("res");

上述时一键登录封装的工具类，根据自己业务去写业务逻辑，然后将工具类中的appkey和appSecret 替换称自己的，这个是服务端的代码，app端需要自己处理
