Java 实现uniapp本机手机号一键登录

这里简单的贴一下后端的解析代码 其他配置项参照uniapp的官方文档配置就好了

这里的accessToken和openid是前端请求uCloud获取的

@Data
public class UniAppLoginVO {private Integer code;private String message;private ResultDataVO data;private Boolean success;private ResultError error;
}

@Data
public class ResultDataVO {private Integer code;private Boolean success;private String phoneNumber;
}

    public User uniAppLogin(String accessToken, String openId) {try {String signStr = "access_token=" + accessToken + "&openid=" + openId;String sign = HmacSHA256Util.hmacSHA256(configMapper.selectConfigByConfigKey(CommonConstant.UNI_APP_LOGIN_KEY), signStr);String body = HttpRequest.get("你的云函数链接地址/getPhoneNumber?" + signStr + "&sign=" + sign).execute().body();UniAppLoginVO uniAppLoginVO = JSONObject.parseObject(body, UniAppLoginVO.class);if (uniAppLoginVO.getCode() == 1) {ResultDataVO resultDataVO = uniAppLoginVO.getData();if (resultDataVO.getSuccess().equals(Boolean.TRUE)) {return verifyLoginByCaptcha(resultDataVO.getPhoneNumber(), null);}else {throw new BasicsBootException("解析手机号失败");}}else {throw new BasicsBootException("服务异常获取手机号失败");}} catch (Exception e) {log.error("uniAppLogin error,{}", e.getMessage());}return null;}

以下是解析生成加密验证sign的工具类

import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;public class HmacSHA256Util {/*** HmacSHA256算法,返回的结果始终是32位* @param key 加密的键，可以是任何数据* @param content 待加密的内容* @return 加密后的内容* @throws Exception*/public static byte[] hmacSHA256(byte[] key,byte[] content) throws Exception {Mac hmacSha256 = Mac.getInstance("HmacSHA256");hmacSha256.init(new SecretKeySpec(key, 0, key.length, "HmacSHA256"));return hmacSha256.doFinal(content);}/*** 将加密后的字节数组转换成字符串** @param b 字节数组* @return 字符串*/public static String byteArrayToHexString(byte[] b) {StringBuilder hs = new StringBuilder();String stmp;for (int n = 0; b!=null && n < b.length; n++) {stmp = Integer.toHexString(b[n] & 0XFF);if (stmp.length() == 1)hs.append('0');hs.append(stmp);}return hs.toString().toLowerCase();}/*** sha256_HMAC加密* @param message 消息* @param secret  秘钥* @return 加密后字符串*/public static String hmacSHA256(String secret, String message) throws Exception {Mac hmacSha256 = Mac.getInstance("HmacSHA256");hmacSha256.init(new SecretKeySpec(secret.getBytes(), "HmacSHA256"));byte[] bytes = hmacSha256.doFinal(message.getBytes());return byteArrayToHexString(bytes);}
}

以上就是所有后台处理的方法及工具类
