今天突然说小程序版本审核要我们处理评论中的敏感词内容，踩了一些坑终于搞好了，贴下代码出来吧，文档说的不是很详细，估计有不少小伙伴踩坑了。
public function keyCheck(){
$wxToken=wxTokenCheck(); //获取微信token
$key = input(‘key’);
$url = ‘https://api.weixin.qq.com/wxa/msg_sec_check?access_token=’.$wxToken['token’];
$data = json_encode([‘content’=>$key],JSON_UNESCAPED_UNICODE); //一定要把中文转成utf8！！！
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_URL,$url); // url
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); // json数据
$res = curl_exec($ch); // 返回值
curl_close($ch);
$result = json_decode($res,true);

    echo "<pre>";
    var_dump($result);
    var_dump($data);
    echo "</pre>";
}
