Node.js Demo

安装AWS SDK for JavaScript in Node.js

npm install aws-sdk

初始化,设置帐号信息和域名


var AWS = require('aws-sdk');
var fs = require('fs');

AWS.config.accessKeyId = 'ziw5dp1alvty9n47qksu'; //请替换为您自己的access_key
AWS.config.secretAccessKey = 'V+ZTZ5u5wNvXb+KP5g0dMNzhMeWe372/yRKx4hZV'; //请替换为您自己的secret_key
AWS.config.region = 'us-west-1';
AWS.config.endpoint = 'http://s2.i.qingcdn.com';
AWS.config.s3ForcePathStyle = true

var s3 = new AWS.S3();

文件操作接口

上传文件

使用putObject接口上传

ACL可设置为:'private' 或 'public-read' 或 'public-read-write' 或 'authenticated-read'

var params = {
    Bucket: 'test-bucket-xxx',
    Key: 'test-key-xxx',
    ACL: 'public-read',
    Body: new Buffer('blablabla')
};
s3.putObject(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});
使用upload接口上传(适合大文件上传,支持自动分块,多块并行上传)
var file_stream = fs.createReadStream('/root/test.mp4')
var params = {
    Bucket: 'test-bucket-xxx',
    Key: 'test-key-xxx',
    Body: file_stream,
    ACL: 'public-read'
}
var options = {partSize: 10 * 1024 * 1024, queueSize: 10}
s3.upload(params, options, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

下载文件

var params = {
    Bucket: 'test-bucket-xxx',
    Key: 'test-key-xxx'
};
s3.getObject(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

获取文件的URL

获取已签名的URL用来下载文件,可通过参数Expires设置签名过期时间。

var params = {
    Bucket: 'test-bucket-xxx',
    Key: 'test-key-xxx',
    Expires: 60
};
var url = s3.getSignedUrl('getObject', params);
console.log('The URL is', url);

删除文件

var params = {
    Bucket: 'test-bucket-xxx',
    Key: 'test-key-xxx'
};
s3.deleteObject(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

获取文件的ACL

var params = {
    Bucket: 'test-bucket-xxx',
    Key: 'test-key-xxx'
};
s3.getObjectAcl(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

设置文件的ACL

使用预定义的ACL

支持的预定义ACL有:'private', 'public-read', 'public-read-write' 或 'authenticated-read'

var params = {
    Bucket: 'test-bucket-xxx',
    Key: 'test-key-xxx',
    ACL: 'public-read'
};
s3.putObjectAcl(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});
使用自定义的ACL

可指定的Permission包括:'FULL_CONTROL', 'WRITE', 'WRITE_ACP', 'READ', 'READ_ACP'

var params = {
    Bucket: 'test-bucket-xxx',
    Key: 'test-key-xxx',
    AccessControlPolicy: {
        Grants: [
            {
                Grantee: {
                    Type: 'CanonicalUser',
                    ID: 'user-foo'
                },
                Permission: 'WRITE'
            },
            {
                Grantee: {
                    Type: 'CanonicalUser',
                    ID: 'your-user-name'
                },
                Permission: 'FULL_CONTROL'
            },
        ],
        Owner: {
            ID: 'your-user-name'
        }
    }
};
s3.putObjectAcl(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

桶操作接口

创建桶

ACL可设置为:'private' 或 'public-read' 或 'public-read-write' 或 'authenticated-read'

var params = {
    Bucket: 'test-bucket-xxx',
    ACL: 'public-read'
};
s3.createBucket(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

列出桶中所包含的文件

var params = {
    Bucket: 'test-bucket-xxx',
};
s3.listObjects(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

删除桶

var params = {
    Bucket: 'test-bucket-xxx',
};
s3.deleteBucket(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

获取桶的ACL

var params = {
    Bucket: 'test-bucket-xxx',
};
s3.getBucketAcl(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);

                    ID: 'user-foo'
                },
                Permission: 'WRITE'
            },
            {
                Grantee: {
                    Type: 'CanonicalUser',
                    ID: 'your-user-name'
                },
