OSS plugin for egg
$ npm i egg-ossTo enable oss plugin, you should change ${baseDir}/config/plugin.js
// config/plugin.js
exports.oss = {
enable: true,
package: 'egg-oss',
};Then fill in nessary information like OSS's bucket, accessKeyId, accessKeySecret in ${baseDir}/config/config.{env}.js
Mention, egg-oss support normal oss client and oss cluster client, based on oss-client:
// normal oss bucket
exports.oss = {
client: {
accessKeyId: 'your access key',
accessKeySecret: 'your access secret',
bucket: 'your bucket name',
endpoint: '{https or http}://{your endpoint name}.aliyun.com',
timeout: '60s',
},
};
// cluster oss bucket
// need to config all bucket information under cluster
exports.oss = {
client: {
cluster: [{
endpoint: '{https or http}://{your endpoint name}.aliyun.com',
accessKeyId: 'id1',
accessKeySecret: 'secret1',
}, {
endpoint: '{https or http}://{your endpoint name}.aliyun.com',
accessKeyId: 'id2',
accessKeySecret: 'secret2',
}],
schedule: 'masterSlave', //default is `roundRobin`
timeout: '60s',
},
};
// if config.sts == true, oss will create STS client
exports.oss = {
client: {
sts: true,
accessKeyId: 'your access key',
accessKeySecret: 'your access secret',
},
};Init in egg agent, default is false:
exports.oss = {
useAgent: true,
};You can aquire oss instance on app or ctx.
The example below will upload file to oss using the file mode of egg-multipart.
const path = require('path');
const Controller = require('egg').Controller;
const fs = require('mz/fs');
// upload a file in controller
module.exports = class extends Controller {
async upload() {
const ctx = this.ctx;
const file = ctx.request.files[0];
const name = 'egg-oss-demo/' + path.basename(file.filename);
let result;
try {
result = await ctx.oss.put(name, file.filepath);
} finally {
await fs.unlink(file.filepath);
}
if (result) {
console.log('get oss object: %j', object);
ctx.unsafeRedirect(result.url);
} else {
ctx.body = 'please select a file to upload！';
}
}
};To learn OSS client API, please check oss document。
Some application need to access more than one oss bucket, then you need to configure oss.clients, and
you can create new oss instance dynamicly by app.oss.createInstance(config).
${appdir}/config/config.default.js
exports.oss = {
clients: {
bucket1: {
bucket: 'bucket1',
},
bucket2: {
bucket: 'bucket2',
},
},
// shared by client, clients and createInstance
default: {
endpoint: '{https or http}://{your endpoint name}.aliyun.com',
accessKeyId: '',
accessKeySecret: '',
},
};
exports.bucket3 = {
bucket: 'bucket3',
};${appdir}/config/plugin.js
exports.oss = true;${appdir}/app.js
module.exports = app => {
const bucket1 = app.oss.get('bucket1');
const bucket2 = app.oss.get('bucket2');
// it will merge app.config.bucket3 and app.config.oss.default
const bucket3 = app.oss.createInstance(app.config.bucket3);
}Create .env file for environment that testcase need.
