Electron-Vue 使用 oss 实现上传、下载

一、安装阿里云 OSS

npm install ali-oss

二、使用 require 进行引用

let OSS = require('ali-oss');

三、上传文件

async doUpload(){
  const _this = this;
  let client = new OSS({
    region:_this.region,
    accessKeyId: _this.keyId,
    accessKeySecret: _this.keySecret,
    bucket:_this.bucket
  });

  try {
    let result = await client.put('srv2.0-nl/test1.jpg', 'C:\\Users\\Administrator\\Desktop\\光速4.jpg')
    console.log('上传成功');
    console.log(result);
  } catch(e) {
    console.log('出错了');
    console.log(e);
  }
}

四、分片上传

const progress = async function(p) {
  //  进度百分比（0-1之间小数）
  console.log(p);
}
async multipartUpload() {
  const _this = this;
  let client = new OSS({
    region:_this.region,
    accessKeyId: _this.keyId,
    accessKeySecret: _this.keySecret,
    bucket:_this.bucket
  });

  try {
    let result = await client.multipartUpload('srv2.0-nl/test1.jpg', 'C:\\Users\\Administrator\\Desktop\\光速3.jpg', {
      progress,
      meta: {
        year: 2017,
        people: 'test'
      }
    });
    console.log(result);
    let head = await client.head('srv2.0-nl/test1.jpg');
    console.log(head);
  } catch (e) {
    // 捕获超时异常
    if (e.code === 'ConnectionTimeoutError') {
      console.log("Woops,超时啦!");
      // do ConnectionTimeoutError operation
    }
    console.log(e)
  }
}

说明：

meta 参数是一个用户自定义的元数据，通过 head 接口可以获取到 object 的 meta 数据。

progress 参数是一个进度回调函数，用于获取上传进度。progress可以是一个 async 函数。

五、下载文件

async download() {
  const _this = this;
  let client = new OSS({
    region:_this.region,
    accessKeyId: _this.keyId,
    accessKeySecret: _this.keySecret,
    bucket:_this.bucket
  });

  try {
    let result = await client.get('srv2.0-nl/test1.jpg', 'C:\\Users\\Administrator\\Desktop\\下载.jpg');
    console.log(result);
  } catch (e) {
    console.log(e);
  }
}
