</html>上面有个接口地址，我用的后端是php接口，返回内容如：
接口文件内容如下：
<?phpnamespace app\index\controller;use think\Controller;
use think\Db;
use think\validate\ValidateRule;
use think\facade\Log;class Share extends Controller
{// 接口入口public function share_form(){$appid='你的公众号appid';$appsecret='公众号秘钥';$this->cache = new \Memcached();$this->cache->addServer('127.0.0.1', 11211);$data = $this->cache->get('access_token');$data = json_decode($data);if(!$data){$data=(object)[];$data->expire_time = time() - 10;}if ($data->expire_time < time()) {$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$appsecret";$ret_json = $this->curl_get_contents($url);$ret = json_decode($ret_json,true);$access_token=$ret['access_token'];$url_ticket = 'https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token='. $access_token .'&type=jsapi';$ret_json_ticket = $this->curl_get_contents($url_ticket);$ret_ticket = json_decode($ret_json_ticket,true);$ticket = $ret_ticket['ticket'];$data->expire_time = time() + 7000;$data->jsapi_ticket = $ticket;$token = json_encode($data);$this->cache->set('access_token', $token, 7000);}else {$ticket = $data->jsapi_ticket;}$noncestr = $this->getRandStr(15);$timestamp = time();$strvalue = 'jsapi_ticket='.$ticket.'&noncestr='.$noncestr.'×tamp='.$timestamp.'&url='.input('url');$signature = sha1($strvalue);return json(['timestamp'=>$timestamp,'nonceStr'=>$noncestr,'signature'=>$signature,'appId'=>$appid,]);}public function getRandStr($length){$str = 'abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';$randString = '';$len = strlen($str)-1;for($i = 0;$i < $length;$i ++){$num = mt_rand(0, $len);$randString .= $str[$num];}return $randString;}function curl_get_contents($url){$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_TIMEOUT, 1);curl_setopt($ch, CURLOPT_MAXREDIRS, 200);
