使用axios上传二进制文件？

npm install axios

import axios from 'axios';

const formData = new FormData();
formData.append('file', binaryData, 'filename.ext');

axios.post('/upload', formData)
  .then(response => {
    // 处理上传成功的逻辑
  })
  .catch(error => {
    // 处理上传失败的逻辑
  });

const express = require('express');
const multer = require('multer');
const app = express();

// 创建存储引擎
const storage = multer.diskStorage({
  destination: function (req, file, cb) {
    // 指定上传文件的保存路径
    cb(null, '/path/to/save/files');
  },
  filename: function (req, file, cb) {
    // 指定文件名
    cb(null, file.originalname);
  }
});

// 创建multer中间件
const upload = multer({ storage: storage });

// 处理文件上传的路由
app.post('/upload', upload.single('file'), function (req, res) {
  // 文件上传成功后的逻辑
  res.send('File uploaded!');
});

// 启动服务器
app.listen(3000, function () {
  console.log('Server started on port 3000');
});
