How to use PHP and Alibaba Cloud OCR to identify the business scope of a business license?

Business license is an important document proving the business activities of a legal person. The business scope describes the type and scope of the company's specific operations. In many scenarios, we need to automate the processing and analysis of business licenses. Therefore, it is particularly critical to use OCR technology to identify the business scope of the business license. This article will introduce how to use PHP and Alibaba Cloud OCR service to implement this function.

First of all, we need to have an Alibaba Cloud account and have activated the OCR service. If you do not have an Alibaba Cloud account, you can first register an account and activate the OCR service.

Next, we need to build a PHP client to call the Alibaba Cloud OCR API. First, we need to install the PHP development package of aliyun-sdk. You can search for "aliyun-sdk-php" on GitHub, and then install the corresponding version of the SDK according to the official documentation.

In the code, we need to introduce the autoloader.php file in the sdk-core directory and configure some basic information, such as AccessKey, AccessSecret, Region, etc. This information can be obtained on the Alibaba Cloud management console.

// 引入SDK的核心文件
require_once "<path_to_sdk_core>/autoload.php";

use DefaultProfile;
use DefaultAcsClient;
use RequestV20180120RecognizeBusinessLicenseRequest;

// 配置AK信息
$accessKeyId = "<your_access_key_id>";  // 替换为你的AccessKeyId
$accessKeySecret = "<your_access_key_secret>";  // 替换为你的AccessKeySecret
$regionId = "cn-hangzhou";  // 替换为你的RegionId

// 创建DefaultAcsClient实例并初始化
$profile = DefaultProfile::getProfile($regionId, $accessKeyId, $accessKeySecret);
DefaultProfile::addEndpoint("cn-hangzhou", "cn-hangzhou", "ocr", "ocr.cn-hangzhou.aliyuncs.com");
$client = new DefaultAcsClient($profile);

// 创建API请求并设置参数
$request = new RecognizeBusinessLicenseRequest();
$request->setAcceptFormat("json");  // 识别结果以json格式返回

// 读取营业执照图片并进行Base64编码
$imagePath = "<path_to_image>";  // 替换为营业执照图片的路径
$imageData = base64_encode(file_get_contents($imagePath));

$request->setImageURL($imageData);

// 发起API请求并解析结果
$response = $client->getAcsResponse($request);
$result = json_decode($response->getBody(), true);

// 输出经营范围
echo $result['Data']['Trade'] . "
";

In the above sample code, we first introduced the core file of the SDK, and then configured AccessKey, AccessSecret, Region and other information. Next, an instance of DefaultAcsClient and a RecognizeBusinessLicenseRequest instance are created to initiate a request to identify the business license. When setting the request parameters, we convert the business license image to Base64 encoding and pass the image data to the API request through the setImageURL method.

Finally, send the request and get the response result through the getAcsResponse method. By parsing out the corresponding fields, you can obtain the identified business scope information and perform subsequent processing.

It should be noted that the above sample code only shows how to call the API of Alibaba Cloud OCR through PHP to identify the business scope of the business license. In actual applications, error handling, parameter verification, etc. may need to be added to improve Code robustness and stability.

To sum up, using PHP and Alibaba Cloud OCR to identify the business scope of a business license requires the following steps: registering an Alibaba Cloud account and activating the OCR service, installing the PHP development package of aliyun-sdk, and writing PHP code To call Alibaba Cloud OCR API, pass in the business license image and parse the recognition results. In this way, we can easily automate and analyze the business scope in the business license.
