Meteor Package: Aliyun storage adaptor for CollectionFS.

中文说明

Installation

$ meteor add iyyang:cfs-aliyun

Aliyun OSS Setup

1. Create Access Key and enable OSS Service on Aliyun.
2. In access key management console, copy the generated key pairs (Access Key ID and Access Key Secret) and paste into your configuration file.
3. Create OSS Bucket, make sure you have rememberd bucket name and region, or paste into configuration file.

Usage

After performimg Installation and Aliyun OSS Setup, we may create CollectionFS storage via the following:

var imageStore = new FS.Store.OSS('images', {
  region: 'oss-my-region', //optional, default is 'oss-cn-hangzhou'
  aliyunInternal: false, //optional, set to true if access from Aliyun ECS
  bucket: 'Bucket Name', //required
  accessKeyId: 'Access Key ID', //required
  secretAccessKey: 'Access Key Secret', //required
  ACL: 'private', //optional, access limit of new files, default is 'private' 
  folder: 'folder/in/bucket', //optional, which folder (key prefix) in the bucket to use 
  // The rest are generic store options supported by all storage adapters
  transformWrite: myTransformWriteFunction, //optional
  transformRead: myTransformReadFunction, //optional
  maxTries: 1 //optional, default 5
});

Images = new FS.Collection('images', {
  stores: [imageStore]
});

Supported options

• Supported regions: 'oss-cn-hangzhou', 'oss-cn-shanghai', 'oss-cn-beijing', 'oss-cn-qingdao', 'oss-cn-shenzhen', 'oss-cn-hongkong', 'oss-us-east-1', 'oss-us-west-1', 'oss-ap-southeast-1'
• Supported ACLs: 'private', 'public-read', 'public-read-write'

Secure your Credential

We must put whatever storage credential to server directory otherwise it is accessble by clients. Note that Meteor.isServer is NOT secure.

We would need to define store in two files, located in client and server directories respectively. And we should not put any options in client file.

Example by cfs:s3:

Client (client/collections_client/avatars.js)

var avatarStoreLarge = new FS.Store.OSS('avatarsLarge');
var avatarStoreSmall = new FS.Store.OSS('avatarsSmall');

Avatars = new FS.Collection('avatars', {
  stores: [avatarStoreSmall, avatarStoreLarge],
  filter: {
    allow: {
      contentTypes: ['image/*']
    }
  }
})

Server (server/collections_server/avatars.js)

var avatarStoreLarge = new FS.Store.OSS('avatarsLarge', {
  region: 'oss-my-region',
  aliyunInternal: false,
  bucket: 'avatars.large',
  accessKeyId: 'ACCESS-KEY-ID-HERE', 
  secretAccessKey: 'ACCESS-KEY-SECRET-HERE',
  transformWrite: function(fileObj, readStream, writeStream) {
    gm(readStream, fileObj.name()).resize('250', '250').stream().pipe(writeStream)
  }
})

var avatarStoreSmall = new FS.Store.OSS('avatarsSmall', {
  region: 'oss-my-region',
  aliyunInternal: false,
  bucket: 'avatars.small',
  accessKeyId: 'ACCESS-KEY-ID-HERE', 
  secretAccessKey: 'ACCESS-KEY-SECRET-HERE', 
  beforeWrite: function(fileObj) {
    fileObj.size(20, {store: 'avatarStoreSmall', save: false});
  },
  transformWrite: function(fileObj, readStream, writeStream) {
    gm(readStream, fileObj.name()).resize('20', '20').stream().pipe(writeStream)
  }
})


Avatars = new FS.Collection('avatars', {
  stores: [avatarStoreSmall, avatarStoreLarge],
  filter: {
    allow: {
      contentTypes: ['image/*']
    }
  }
})

This package is inspired by cfs:s3 package, where we have introduced Aliyun SDK and created our own version for OSS. We have slightly optimized stream handling.
