h5怎么在微信公众号发布（H5微信公众号授权的简单实现步骤）

import React, { useEffect } from "react";
import { View } from "@tarojs/components";

export default () => {
  useEffect(() => {
    // 后端回调回来路径格式：http://xxx.cn/#/pages/webAuthorization?bindFlag=0&openid=xxxxxxxxxxx&unionid=null&isAuth=true
    
    var isBindFlag = false, isAuth = false, opendId = '', paramsArray = [];


    /*
     * 省略代码：地址判断，参数处理 赋值给isAuth, isBindFlag, openId
     */ 

    if (!isAuth) {							// 未授权
      window.location.href=`https://open.weixin.qq.com/connect/oauth2/authorize?appid=${'xxxxxxx'}&redirect_uri=http://xxxxx/api/auth?response_type=code&scope=snsapi_userinfo&state=STATE&connect_redirect=1#wechat_redirect`;
    } else if (!isBindFlag) {   // 未注册
      window.location.href = '#/pages/login'
    } else {               			// 登录
      window.location.href = '#/pages/index'
    }
  }, []);

  return (
    <View>
    </View>
  );
};
