Steps and precautions for PHP to implement docking with Baidu text review API

Introduction:
With the rapid development of the Internet, users’ behavior on the Internet has also become more and more complex. In order to maintain a good network environment and user experience, many platforms have introduced text review systems. As a commonly used text content security detection service, Baidu Text Review API can effectively help the platform detect and filter sensitive information, spam and other inappropriate content. This article will introduce how to use PHP to connect to Baidu text review API, and pay attention to some matters that need attention.

Step 1: Register a Baidu Smart Cloud account and create an application
Before starting, we need to register a Baidu Smart Cloud account and create an application to obtain the API Key and Secret Key. These two keys will used in subsequent operations.

Step 2: Install Baidu AI SDK
First, we need to download and install Baidu AI SDK, which can be installed through Composer. Enter the following command in the terminal:

composer require baidu-aip/php-sdk

Step 3: Write code
In the PHP code, we need to use the relevant classes and methods provided by the PHP SDK to achieve docking with the Baidu text review API. The following is a simple sample code that shows how to use PHP to send a text review request and get the results:

<?php
require_once 'vendor/autoload.php';

use AipContentCensorAipContentCensor;

// 定义常量
const APP_ID = 'your_app_id';
const API_KEY = 'your_api_key';
const SECRET_KEY = 'your_secret_key';

// 初始化客户端
$client = new AipContentCensor(APP_ID, API_KEY, SECRET_KEY);

// 发送请求
$text = '需要审核的文本内容';
$options = array();  // 可选参数

$response = $client->textCensorUserDefined($text, $options);

// 处理响应结果
if ($response['conclusionType'] == 1) {
    echo "不合规";
} elseif ($response['conclusionType'] == 2) {
    echo "疑似";
} else {
    echo "合规";
}

Step 4: Configure API parameters and options
In the code, we need to add the values ​​created in the previous step Fill in the API Key and Secret Key generated by the application. At the same time, you can set relevant optional parameters through the $options array according to business needs, such as filtering sensitive words, violent and terrorist words, etc.

Step 5: Process the response result
The response result of Baidu text review API is an array in JSON format, in which the conclusionType field indicates the type of review result, 1 indicates non-compliance, 2 means suspected, 0 means compliant. According to specific business needs, we can perform corresponding processing based on the value of the conclusionType field.

4. For the review of long texts, it is recommended to segment the text content.

Conclusion:
Through the above steps, we can easily use PHP to connect to Baidu text review API and implement security review of text content. I hope this article will help you understand and use Baidu text review API, and avoid some common problems during the docking process.
