The external browser calls H5 to call up the WeChat applet.
This time I used the applet scheme code to jump to the applet
PHP server
<?php
namespace app\index\controller;
use think\Db;
use think\Controller;
class Mini extends Controller
{
public $appid = '你的appid';
public $secret = '你的secret';
public function index()
{
$url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$this->appid.'&secret='.$this->secret;
$data = $this->curl_get($url);
$access_token = json_decode($data,true)['access_token'];
$post_data['jump_wxa']['path'] = '/pages/web_view/index';
$post_data['jump_wxa']['query'] = '2';
$post_data = json_encode($post_data);
$post_url = 'https://api.weixin.qq.com/wxa/generatescheme?access_token='.$access_token;
$result = $this->curl_post($post_url,$post_data);
$jumpUrl = json_decode($result,true)['openlink'];
return view('index',[
'openlink'=>$jumpUrl,//跳转路径
]);
}
//curl get方式
public function curl_get($url)
{
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$data = curl_exec($curl);
curl_close($curl);
return $data;
}
//curl post方式
public function curl_post($url, $post_data = '', $timeout = 3000)
{
header("Content-type:text/html;charset=utf-8");
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_HEADER, false);
$file_contents = curl_exec($ch);
curl_close($ch);
return $file_contents;
}
}
H5 end
