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 = this
			that.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.data
							return;
						}
					}
				});
			}
		}
	}
</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
