首先需要在百度智能云上注册号

（其注册步骤可参考CSDN博客）

代码实现

将以下代码放置控制器即可，或者进行封装调用

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class Audit
{
    /**
     * 内容审核
     */
    public function contentAudit(Request $request)
    {
        $content = $request->post('content');
        //ApiKey和SecretKey从自己在百度智能云上创建的应用信息里获取
        $token = $this->getAccessToken('ApiKey ', 'SecretKey ');

        $url = 'https://aip.baidubce.com/rest/2.0/solution/v1/text_censor/v2/user_defined?access_token=' . $token;

        $bodys = array(
            'text' => $content
        );

        $res = $this->curlPost($url, $bodys);

        //结果转成数组
        $res = json_decode($res, true);

        //根据自己的业务逻辑进行处理

        return $res;
    }

    /**
     * 图片审核
     */
    public function imageAudit()
    {

        $fileTmp = $request->file('image')->getPathname();
        $token = $this->getAccessToken('ApiKey ', 'SecretKey ');
        $url = 'https://aip.baidubce.com/rest/2.0/solution/v1/img_censor/v2/user_defined?access_token=' . $token;
        $img = file_get_contents($fileTmp);//本地路径
        $img = base64_encode($img);
        $bodys = array(
            'image' => $img
        );
        $res = $this->curlPost($url, $bodys);
        //结果转成数组
        $res = json_decode($res, true);
        //根据自己的业务逻辑进行处理
        return $res;
    }

        $curlPost = $param;
        // 初始化curl

        curl_setopt($curl, CURLOPT_URL, $postUrl);
        curl_setopt($curl, CURLOPT_HEADER, 0);
        // 要求结果为字符串且输出到屏幕上
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        // post提交方式
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $curlPost);
        // 运行curl
        $data = curl_exec($curl);
