Use PHP and Qiniu cloud storage interface to realize the pornographic identification and sensitive information detection functions of pictures

Introduction:
With the development of the Internet, the dissemination of pictures is becoming more and more widespread, but there are also some Some pictures that are pornographic or contain sensitive information. In order to filter these bad pictures, we can use the interface of Qiniu Cloud Storage and combine it with the PHP programming language to implement pornography and sensitive information detection functions for uploaded pictures. This article will introduce how to use PHP to write code and combine it with the Qiniu cloud storage interface to implement this function.

1. Introduction to Qiniu Cloud Storage
Qiniu Cloud Storage is a well-known cloud storage service provider that provides powerful storage and data management functions. We can operate the uploaded images through the interface of Qiniu Cloud Storage, such as uploading, downloading, deleting, etc. This article will mainly use the pornographic identification and sensitive information detection interface of Qiniu Cloud Storage.

2. PHP installation and configuration
First, we need to install PHP and configure the environment. For specific installation steps, please refer to official documentation or online tutorials. After the installation is complete, we need to ensure that the relevant PHP plug-ins are installed and enabled. We can view the installed plug-ins by executing the php -m command to ensure that the curl and fileinfo plug-ins are included.

3. Qiniu Cloud Storage Interface Call

1. Get the Access Key and Secret Key of Qiniu Cloud Storage
   Before using the Qiniu Cloud Storage interface, we need to obtain it first Access Key and Secret Key. We can log in to the official website of Qiniu Cloud Storage, enter the personal center, and obtain these two keys on the key management page.
2. Upload pictures to Qiniu Cloud Storage
   In PHP, we can use the PHP SDK of Qiniu Cloud Storage to complete the upload operation. The following is a sample code for uploading images:

<?php
require_once 'autoload.php';  //加载七牛云存储SDK

use QiniuAuth;
use QiniuStorageUploadManager;

$accessKey = 'your_access_key';
$secretKey = 'your_secret_key';

$auth = new Auth($accessKey, $secretKey);
$bucket = 'your_bucket_name';

$token = $auth->uploadToken($bucket);

$uploadMgr = new UploadManager();

//上传图片
list($ret, $err) = $uploadMgr->putFile($token, $key, $filePath);

if ($err !== null) {
    die('上传失败：' . $err->message());
} else {
    echo '上传成功';
}
?>

In the code, we first introduce the SDK of Qiniu Cloud Storage, and then create an authentication object based on the obtained Access Key and Secret Key. Next, we set the name of the storage space (bucket) and the token carried in the upload. Finally, create an UploadManager object and call the putFile method to upload the image.

4. Use the pornography identification and sensitive information detection interface of Qiniu Cloud Storage

1. Activate the pornography identification and sensitive information detection function
   Use the pornography identification and sensitive information detection interface Before that, we need to enable this function first. We can log in to the official website of Qiniu Cloud Storage, find the storage space management page, and then turn on the pornography and sensitive information detection functions in the advanced settings.
2. Use pornography and sensitive information detection interface
   Using the pornography and sensitive information detection interface of Qiniu Cloud Storage, we can determine whether the picture contains pornography or sensitive information. The following is a sample code for using pornography and sensitive information detection interfaces:

<?php
require_once 'autoload.php';  //加载七牛云存储SDK

use QiniuAuth;
use QiniuStorageBucketManager;

$accessKey = 'your_access_key';
$secretKey = 'your_secret_key';

$auth = new Auth($accessKey, $secretKey);
$bucket = 'your_bucket_name';

$bucketMgr = new BucketManager($auth);

$uri = 'your_image_uri';

//调用鉴黄和敏感信息检测接口
$response = $bucketMgr->imageCensor($bucket, $uri);

if ($response[0]['code'] === 0) {
    echo '图片没有包含色情或敏感信息';
} else {
    echo '图片包含色情或敏感信息';
}
?>

In the code, we also need to introduce the SDK of Qiniu Cloud Storage and create authentication based on the obtained Access Key and Secret Key. object. Then, create a BucketManager object and call the imageCensor method to pass in the name of the storage space (bucket) and the URI of the image for detection. Finally, determine whether the image contains pornographic or sensitive information based on the return result of the interface.

Summary:
Through the combination of PHP and Qiniu cloud storage interface, we can realize the pornographic identification and sensitive information detection functions of uploaded pictures. Through the above code example, after the image is uploaded to Qiniu Cloud Storage, we can use the pornographic identification and sensitive information detection interface to determine whether the image contains pornographic or sensitive information. This function has important application value in scenarios such as content review and social platform management. I hope this article was helpful to you, thanks for reading!
