PHP利用百度ai实现文本和图片审核

之前做平台内容发布审核都是自己构建一套违禁词库，在代码中利用词库判断用户发布的内容，现在可以使用百度ai api完成这个功能。接下来就简单说下怎么做吧：

首先打开百度ai 开发平台 注册一个账号：

注册账号，进入控制台

创建自己的应用，获取apikey 和秘钥

进入文档页 文本审核：

图像审核：

文档很详细，实现用户发布内容审核 图片审核还是很方便简单的。我没有使用官方的sdk，简单的整合了一下作为练手，以下是我简单的代码demo:

class Sentive
{
  protected $accessTokenUrl = 'https://aip.baidubce.com/oauth/2.0/token';//获取token url
  protected $textUrl = 'https://aip.baidubce.com/rest/2.0/antispam/v2/spam';//文本审核url
  protected $imgUrl = 'https://aip.baidubce.com/api/v1/solution/direct/img_censor';//图片审核url
  protected $avatarUrl = 'https://aip.baidubce.com/rest/2.0/solution/v1/face_audit';//头像审核url

  protected $grant_type;

  protected $client_id;

  protected $client_secret;

  function __construct()
  {
    $this->grant_type = 'client_credentials';
    $this->client_id = 'xxx';//API Key
    $this->client_secret = 'xxx';//Secret Key
  }

  static function request($url = '', $param = '')
  {
    if (empty($url) || empty($param)) {
      return false;
    }

    $postUrl = $url;
    $curlPost = $param;
    $curl = curl_init();//初始化curl
    curl_setopt($curl, CURLOPT_URL, $postUrl);//抓取指定网页
    curl_setopt($curl, CURLOPT_HEADER, 0);//设置header
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);//要求

结果为字符串且输出到屏幕上 curl_setopt($curl, CURLOPT_POST, 1);//post提交方式 curl_setopt($curl, CURLOPT_POSTFIELDS, $curlPost); $data = curl_exec($curl);//运行curl curl_close($curl); return $data; } static function request_post($url = '', $param = array(), $type) { if (empty($url) || empty($param)) { return false; } $postUrl = $url; $curlPost = $param; $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $postUrl); curl_setopt($curl, CURLOPT_HEADER, 0); // 要求结果为字符串 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // post方式 curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_POSTFIELDS, $curlPost); if ($type == "text") { curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded')); } else { curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/json;charset=utf-8')); } curl_setopt($curl, CURLINFO_HEADER_OUT, true); $data = curl_exec($curl); $code = curl_getinfo($curl, CURLINFO_HTTP_CODE); if ($code === 0) { throw new \Exception(curl_error($curl)); } curl_close($curl); return $data; } //获取token public function getToken() { new Redis(); $post_data['grant_type'] = $this->grant_type; $post_data['client_id'] = $this->client_id; $post_data['client_secret'] = $this->client_secret; $o = ""; foreach ($post_data as $k => $v) { $o .= "$k=" . urlencode($v) . "&"; } $post_data = substr($o, 0, -1); $res = self::request($this->accessTokenUrl, $post_data); $redis->setkey("filterToken", json_decode($res, true)['access_token']); return json_decode($res, true)['access_token']; } //文本审核 public function textVerify($data) { new Redis(); $token = $redis->get("filterToken"); if (empty($token)) { $token = $this->getToken(); } $curl = $this->textUrl . "?access_token=" . $token; $result = self::request_post($curl, $data, "text"); return json_decode($result, true); } //图片审核 public function imgVerify($img) { $redis = new Redis(); $token = $redis->get("filterToken"); if (empty($token)) { $token = $this->getToken(); } $curl = $this->imgUrl . "?access_token=" . $token; $bodys = array( 'image' => $img, 'scenes' => array("ocr", "face", "public", "politician", "antiporn", "terror", "webimage", "disgust", 'watermark') ); $bodys = json_encode($bodys); $result = self::request_post($curl, $bodys, "img"); return json_decode($result, true); } //头像审核 public function avatarVerify($img) { $redis = new Redis(); $token = $redis->get("filterToken"); if (empty($token)) { $token = $this->getToken(); } $curl = $this->avatarUrl . "?access_token=" . $token; $bodys = array( "configId" => "1", "images" => $img ); $result = self::request_post($curl, $bodys, "text"); return json_decode($result, true); } }
