php实现微信小程序内容安全接口校验

define('MSG_SEC_CHECK','https://api.weixin.qq.com/wxa/msg_sec_check?');//小程序敏感词检查

define('IMG_SEC_CHECK','https://api.weixin.qq.com/wxa/img_sec_check?');//小程序图片检查

define('OAUTH_TOKEN_URL','https://api.weixin.qq.com/cgi-bin/token?');  //获取授权access_token

//检测敏感词

function msg_sec_check($appid,$secret,$content){

    $web_access_token = get_access_token($appid,$secret);

    $params = [

        'access_token' => $web_access_token,

    ];

    $request_params = to_url_params($params);

    $url = MSG_SEC_CHECK . $request_params;

    $data = json_encode(['content'=>$content],JSON_UNESCAPED_UNICODE);//网上看到的基本都是直接让中文给json转义了，实测json转义后无法检测出实际违规内容

    $result = json_decode(curl_request($url, $data, true));

    //返回数据自行根据自己需要进行判断

    return $result;

}

//图片检测（$media参数格式为['media'=>new \CURLFile()],php5.5以上）

function img_sec_check($appid,$secret,$media){

    $web_access_token = get_access_token($appid,$secret);

    $params = [

        'access_token' => $web_access_token,

    ];

    $request_params = to_url_params($params);

    $url = IMG_SEC_CHECK . $request_params;

    $result = json_decode(curl_request($url, $media, true));

    //返回数据自行根据自己需要进行判断

    return $result;

}

//获取微信access_token(自行优化一下，可存缓存)

function get_access_token($appid,$secret){

    $params = [

        'grant_type' => 'client_credential',

        'appid' => $appid,

        'secret' => $secret,

    ];

    $request_params = to_url_params($params);

    $url = OAUTH_TOKEN_URL . $request_params;

    $result = json_decode(curl_request($url), true);

    //返回数据自行根据自己需要进行判断

    return $result['access_token'];

}

//参数处理

function to_url_params($params){

    $buff = "";

    foreach ($params as $k => $v) {

        if ($k != "sign") {

            $buff .= $k . "=" . $v . "&";

        }

    }

    $buff = trim($buff, "&");

    return $buff;

}

function curl_request($url = '', $postData = '', $options = array()){

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    if (!empty($postData)) {

        curl_setopt($ch, CURLOPT_POST, 1);

        curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);

    }

    curl_setopt($ch, CURLOPT_TIMEOUT, 30); //设置cURL允许执行的最长秒数

    if (!empty($options)) {

        curl_setopt_array($ch, $options);

    }

    //https请求 不验证证书和host

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

    $data = curl_exec($ch);

    curl_close($ch);

    return $data;

}

使用案例

//敏感词

$appid = "";

$secret = "";

$content = "敏感词";//自己想

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

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

//图片检测

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

$media = ['media'=>'@'.realpath($file)];//php<5.5(未实测,可能缺少mine参数)

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