uni-id 是 uniapp 自带的一套用户用户体系，按照官方文档的说法，具有颇多优势。目前闺蜜圈项目是自建用户体系，但是为了后续的功能规划，可能需要用到 uni-id 的账号体系，所以提前进行了相关可行性测试。

99%的应用，都要开发用户注册、登录、发送短信验证码、修改密码、密码加密保存、密码防探测、token管理、页面访问权限、注册用户统计等众多功能，从前端到后端都需要。

为什么不能有一个开源的通用项目，避免大家的重复开发呢？

uni-id应需而生。

uni-id为uniCloud开发者提供了开源、易用、安全、丰富、可扩展的用户管理框架。

clientDB、DB Schema、uni-starter、uni-admin，这些产品都基于uni-id的账户体系。可以说uni-id是uniCloud不可或缺的基础能力。

同时针对已经有账号体系的系统提供了接口，实现数据互通：https://doc.dcloud.net.cn/uniCloud/uni-id/cloud-object.html#external-register

本身就提供了三个接口，没有查询用户信息的功能，按照官网文档实现数据对接也比较容易，不过需要注意的是，文档里面有些内容没有写清楚。

校验算法代码：

import hmac
import hashlib
import time

# https://doc.dcloud.net.cn/uniCloud/uni-id/cloud-object.html#http-reqeust-auth
class Sign:
    def __init__(self, requestAuthSecret):
        self.requestAuthSecret = requestAuthSecret

    def get_signature(self, params, nonce, timestamp):
        params_str = self.get_params_string(params)
        signature = hmac.new(bytes("%s%s" % (self.requestAuthSecret, nonce), 'utf-8'),
                             bytes("%s%s" % (timestamp, params_str), 'utf-8'),
                             digestmod=hashlib.sha256).hexdigest().upper()

        return signature

    def get_params_string(self, params):
        params_str = []
        for k in sorted(params):
            if isinstance(params[k], (list, dict)):
                continue
            params_str.append("%s=%s" % (k, params[k]))

        return "&".join(params_str)


if __name__ == "__main__":
    requestAuthSecret = "testSecret"
    nonce = "xxxxxxx"
    timestamp = int(round(time.time() * 1000))

    params = {
        "foo": 1,
        "bar": 2,
        "foobar": 4,
        "foo_bar": 3,
    }

    sign = Sign(requestAuthSecret)
    signature = sign.get_signature(params, nonce, timestamp)

    print(nonce, timestamp, signature)

对应三个接口的代码封装：

import datetime
import json
import random
import string
import requests
import asyncio
import traceback
import time

from reminder.utils.string_util import random_str
from reminder.utils.uni_sign import Sign as UniSign

requestAuthSecret = 'mysecret' #需要去uniadmin配置文件中设置
sign = UniSign(requestAuthSecret)

post body需要是下面的格式：

req_body = {

    "params": body
}

上述内容在文档中没有说明，需要自己添加clientInfo以及对应的字段。
