使用案例

//敏感詞

$appid = "";

$secret = "";

$content = "敏感詞";//自己想

$file = "./uploads/images/abc.jpeg";

msg_sec_check($appid,$secret,$content);

//圖片檢測

$media = ['media'=>new \CURLFile(realpath($file),'image/jpeg')];//php>=5.5

$media = ['media'=>'@'.realpath($file)];//php<5.5(未實測,可能缺少mine參數)

img_sec_check($appid,$secret,$media);
