svg文本转为对应图片的base64编码
转换脚本（node）
npm init -y
npm install express sharp body-parser
const express = require('express');
const bodyParser = require('body-parser');
const sharp = require('sharp');const app = express();
const port = 5000;// 配置body-parser以接受JSON格式的数据
app.use(bodyParser.json());app.post('/convert-svg', async (req, res) => {try {// 从请求体中获取svg_contentconst svg = req.body.svg_content;const pngBuffer = await sharp(Buffer.from(svg)).toFormat('png').toBuffer();const base64PNG = pngBuffer.toString('base64');res.send(base64PNG);} catch (error) {console.error('Error converting SVG to PNG:', error);res.status(500).send('An error occurred during the conversion process.');}
});app.listen(port, () => {console.log(`Server running at http://localhost:${port}`);
});python测试脚本
