node 阿里云oss上传删除修改文件

在Node.js中使用阿里云OSS进行文件上传、删除和修改，首先需要安装阿里云官方提供的SDK：

npm install ali-oss

以下是使用阿里云OSS SDK进行上传、删除和修改文件的示例代码：

const OSS = require('ali-oss');
 
async function uploadFile() {
  const client = new OSS({
    region: '<Your region>',
    accessKeyId: '<Your accessKeyId>',
    accessKeySecret: '<Your accessKeySecret>',
    bucket: '<Your bucket name>',
  });
 
  try {
    // const result = await client.put('目标文件名', '本地文件路径');
    const result = await client.put('object-key', 'local-file');
    console.log(result);
  } catch (e) {
    console.error(e);
  }
}
 
async function deleteFile() {
  const client = new OSS({
    region: '<Your region>',
    accessKeyId: '<Your accessKeyId>',
    accessKeySecret: '<Your accessKeySecret>',
    bucket: '<Your bucket name>',
  });
 
  try {
    const result = await client.delete('object-key');
    console.log(result);
  } catch (e) {
    console.error(e);
  }
}
 
async function modifyFile() {
  const client = new OSS({
    region: '<Your region>',
    accessKeyId: '<Your accessKeyId>',
    accessKeySecret: '<Your accessKeySecret>',
    bucket: '<Your bucket name>',
  });
 
  try {
    // 首先删除原有文件
    await client.delete('object-key');
 
    // 然后上传新文件
    const result = await client.put('object-key', 'new-local-file');
    console.log(result);
  } catch (e) {
    console.error(e);
  }
}
 
// 调用函数
uploadFile(); // 上传文件
deleteFile(); // 删除文件
modifyFile(); // 修改文件
