一、绑定云空间及创建云函数

• package.json

{"name": "server-push","dependencies": {},"main": "index.js","extensions": {"uni-cloud-push": {}}
}

• index.js

'use strict';
const uniPush = uniCloud.getPushManager({appId:"__UNI__5630355"}) //注意这里需要传入你的应用appId，用于指定接收消息的客户端
exports.main = async (event, context) => {//event为客户端上传的参数console.log('event : ', event);let obj = JSON.parse(event.body)console.log('obj : ', obj);const res = await uniPush.sendMessage({"push_clientid": obj.cids, // 设备id，支持多个以数组的形式指定多个设备，如["cid-1","cid-2"]，数组长度不大于1000  "title": obj.title, // 标题  "content": obj.content, // 内容  "payload": obj.data, // 数据  "force_notification": true, // 服务端推送 需要加这一句  "request_id": obj.request_id //请求唯一标识号，10-32位之间；如果request_id重复，会导致消息丢失   })//返回数据给客户端return res
};

二、编写发送界面

<template><view class="content"><view class="text-area"><text class="title">通知标题：</text><input class="uni-input" v-model="title" placeholder="输入标题" /></view><view class="text-area"><text class="title">通知内容：</text><input class="uni-input" v-model="content" placeholder="输入标题" /></view><text class="title">接收的设备：</text><text v-for="(item, index) in deviceIds"  >{{item}}</text><button @click="send">发送</button></view>
</template><script>export default {data() {return {deviceIds:[],//接收消息的设备title: '我是通知标题',content:'我是通知内容'+Math.floor(Math.random() * 100),}},onLoad() {uni.getPushClientId({success: (res) => {let push_clientid = res.cidconsole.log('客户端推送标识cid:', push_clientid,typeof push_clientid)this.deviceIds.push(push_clientid)}})},methods: {send(){console.log('aaaaaaaa');let send_data = {cids: this.deviceIds, // 使用存储的设备 IDtitle: this.title,content: this.content,data: {},request_id: "",};uniCloud.callFunction({name: "server-push", // 填写你自己的云函数名称data: {body: JSON.stringify(send_data) // 将数据转换为 JSON 字符串并赋值给 body},success(dataRes) {console.log("云函数返回的参数", dataRes)},fail(err) {console.log("云函数报错", err)},complete() {}})}}}
</script><style>.content {display: flex;flex-direction: column;align-items: center;justify-content: center;}.text-area {display: flex;justify-content: center;}.title {font-size: 36rpx;color: #8f8f94;}
</style>
