### Python - 创建和激活虚拟环境

Source: https://help.aliyun.com/zh/ocr/getting-started/getting-started

此命令用于创建一个名为".venv"的Python虚拟环境，以隔离项目依赖。成功创建后，根据您的操作系统（Windows、macOS或Linux）运行相应的激活命令来启用虚拟环境。

```bash
# 如果运行失败，您可以将python替换成python3再运行
python -m venv .venv
```

```bash
# Windows 系统激活命令
.venv\Scripts\activate
```

```bash
# macOS 或 Linux 系统激活命令
source .venv/bin/activate
```

### Check Java Installation (Shell)

Source: https://help.aliyun.com/zh/ocr/developer-reference/sdk-overview

Checks if Java is installed on the system and displays its version. Requires Java 8 or higher. The output format typically starts with 'openjdk version "X.Y.Z" ...' or 'java version "X.Y.Z" ...'.

```shell
java -version

Example of how to call the RecognizeTradeMarkCertification API using the Aliyun SDK for Node.js. This snippet illustrates setting up the client with your credentials and region, sending the image URL, and logging the response. Ensure you have the Aliyun SDK for Node.js installed.

```javascript
const Ocr20191230 = require('@alicloud/ocr-20191230');
const openApiSdk = require('@alicloud/openapi-client-sdk');

async function recognizeTradeMarkCertification(client) {
    const request = new Ocr20191230.RecognizeTradeMarkCertificationRequest({
        imageURL: 'https://img.alicdn.com/tfs/TB1SZiGdfb2gK0jSZK9XXaEgFXa-1654-2340.png' // Replace with your image URL
    });

    try {
        const response = await client.recognizeTradeMarkCertification(request);
        console.log('RequestId:', response.body.requestId);
        console.log('Data:', response.body.data);
        // Process the response data as needed
    } catch (error) {
        console.error('Error calling API:', error);
    }
}

// Replace with your actual AccessKey ID and Secret
openApiSdk.default(Object.assign({
    accessKeyId: 'YOUR_ACCESS_KEY_ID',
    accessKeySecret: 'YOUR_ACCESS_KEY_SECRET',
    // Replace with your actual region ID
    endpoint: 'ocr.cn-hangzhou.aliyuncs.com',
    apiVersion: '2019-12-30'
}))
.then(client => {
    recognizeTradeMarkCertification(client);
})
.catch(err => {
