php版 短信跳转微信小程序

实现这功能首先，小程序端添加业务域名 

php代码

<?php
declare (strict_types=1);namespace app\controller\Admin;use app\model\Set;
use app\Request;class Admin_Url_Scheme
{public function getScheme(Request $request) {$appid = '小程序appid';$secret = '小程序appsecret';//path是要跳转的小城页面地址,query为要携带的参数$body = ['jump_wxa'=>['path'=>'/pages/index/index','query'=>$scheme['name']]];$tokenurl = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=' . $appid . '&secret=' . $secret;$data = file_get_contents($tokenurl);$data = json_decode($data, true);$token = $data['access_token'];$url = "https://api.weixin.qq.com/wxa/generatescheme?access_token=" . $token;$data = $this->curl_post($url, null, $body);if ($data['errmsg'] == 'ok'){return json(['code' => 200,'data'=>$data['openlink'], 'msg' =>'操作成功']);}else{return json(['code' => 201,'data'=>$data, 'msg' =>'异常']);}}function curl_post($url,$herder,$body){
//一般框架都会自带GuzzleHttp,没有的请手动安装,或者利用curl post请求$client = new \GuzzleHttp\Client();try {$pram = $client->post($url,['headers'=>$herder,'json'=>$body,]);$content = json_decode($pram->getBody()->getContents(),true);return $content;}catch (ErrorException $exception){return $exception->getCode();}}
}

下面使用js的location.href

location.href = 'https://***.***.com'

我前端用的是uniapp，vue的话要安装axios或者jq

<template><view class="content"><image class="logo" src="/static/logo.png"></image></view>
</template><script>export default {data() {return {}},onLoad() {const that = thisthat.getScheme()},methods: {getScheme() {uni.request({url: 'https://***.****.com/admin/scheme', //仅为示例，并非真实接口地址。data: {name: 'qiqvxinxikeji'},success: (res) => {if (res.data.code === 200) {location.href = res.data.datareturn;}}});}}}
</script><style lang="scss">.content{font-family: 'Avenir', Helvetica, Arial, sans-serif;-webkit-font-smoothing: antialiased;-moz-osx-font-smoothing: grayscale;text-align: center;color: #2c3e50;margin-top: 60px;}
</style>

短信内容放前端链接地址，这样就可以通过打开游览器跳转到小程序了

注意

1.必须是发布的小程序才会被唤醒

2.接口有上限，如果需求不高不用理会

解决方法就是在请求的时候用redis存储url scheme返回的地址和请求时间， 设置一段时间再次发送新的请求再次覆盖存储数据
