uni-app 开发小程序时会用到推送 前端基于基础用法做一个封装

import {
    appid,
    secret
} from "@/conf/website.js"

/**
 * @description 用户打开订阅提示
 * @param {Array}tmplId  模版id
 * */
export const openSubscription = (tmplIds) => {
    uni.requestSubscribeMessage({
        tmplIds: tmplIds,
        success: (res) => {
            // 订阅成功
        },
        fail: function(err) {
            uni.showToast({
                title: err,
                duration: 2000,
                icon: 'error'
            });
        }
    })
}

/**
 * @description 获取微信的access_token

function get_wx_access_token() {
    return uni.request({
        method: 'get',

        dataType: 'json',
        timeout: 30000
    }).then(res => {
        let [err, success] = res
        if (success.statusCode == 200) {
            return success.data.access_token
        }
    })
}
