通过PHP调用msgSecCheck,无论什么内容均返回OK,无问题,即使是很明显的违规词也返回无问题。
而且看过相关的问题处理,已经是post提交,且验证的内容也是utf-8。
$checkContent = '要检测的内容';
$url = 'https://api.weixin.qq.com/wxa/msg_sec_check?access_token=ACCESS_TOKEN';
$data = json_encode(array('content'=>$checkContent));
$ch = curl_init();
curl_setopt($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 ""
;
var_dump($result);
echo "
";
?>
最后结合社区回答解决了问题:
1、就是必须是post提交;
2、必须是utf-8编码,这个地方不是对你要验证的内容是utf-8编码,而是你进行json_encode编码时,最后编码的数据是 utf-8编码,
原因如下:
$data = json_encode(array('content'=>$checkContent),JSON_UNESCAPED_UNICODE)
然后再调用
msgSecCheck的api。
JSON_UNESCAPED_UNICODE(中文不转为unicode ,对应的数字 256)
虽然mb_detect_encoding验证单独的内容已经是utf-8,但是json编码是不使用JSON_UNESCAPED_UNICODE,$data其实是ASCII编码,而非utf-8,就导致验证什么内容均可通过检测
