步骤：

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：

代码实例：

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) .
