1.安装插件
npm i egg-oss --save
2.开启oss插件
配置路径：{app_root}/config/plugin.js
oss : {
enable: true,
package: 'egg-oss',
}
3.配置阿里云oss参数
配置路径：{app_root}/config/config.plugin.js
config.multipart = {
mode: 'file'
};
config.oss = { // 这里需要的东西去自己的服务器里看，我用的阿里云
client: {
accessKeyId: 'xxxx',
accessKeySecret: 'xxxxx',
bucket: 'xxxxxx',
endpoint: 'xxxxxx',
timeout: '60s',
},
}
4.控制器
'use strict';
const Controller = require('egg').Controller;
const fs = require('mz/fs');
const path = require('path')
class AliyunossController extends Controller {
// 上传
async upload() {
const ctx = this.ctx;
const file = ctx.request.files[0];
if (!file) {
return ctx.apiFail('请先选择上传文件');
}
const name = 'movie/' + ctx.genID(10) + path.extname(file.filename);
let result;
try {
result = await ctx.oss.put(name, file.filepath);
} catch (err) {
console.log(err);
} finally {
await fs.unlink(file.filepath);
}
if (result) {
return ctx.apiSuccess(result.url);
}
ctx.apiFail('上传失败');
}
}
module.exports = AliyunossController;
5.封装的api扩展（非必须）
路径：app/extend/context.js
module.exports = {
// 成功提示
apiSuccess(data = '', msg = 'ok', code = 200) {
this.body = { msg, data };
this.status = code;
},
// 失败提示
apiFail(data = '', msg = 'fail', code = 400) {
this.body = { msg, data };
this.status = code;
},
// 生成唯一id
genID(length) {
return Number(Math.random().toString().substr(3, length) + Date.now()).toString(36);
}
};
6.路由
配置地址：app/router.js
router.post('/api/aliyunoss/upload', controller.aliyunoss.upload);
7.测试文件
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>上传图片至阿里云oss测试</title>
</head>
<body>
<form method="POST" action="http://127.0.0.1:7001/api/aliyunoss/upload" enctype="multipart/form-data">
文件: <input name="file" type="file" />
<button type="submit">上传</button>
</form>
</body>
</html>
