安装

npm install qiniu

获取 ACCESS_KEY 和 SECRET_KEY

要对接七牛云存储服务,您需要七牛云存储服务端颁发给您的 ACCESS_KEYSECRET_KEYACCESS_KEY 用于标识客户方的身份,在网络请求中会以某种形式进行传输。SECRET_KEY 作为私钥形式存放于客户方本地并不在网络中传递,SECRET_KEY 的作用是对于客户方发起的具体请求进行数字签名,用以保证该请求是来自指定的客户方并且请求本身是合法有效的。使用 ACCESS_KEY 进行身份识别,加上 SECRET_KEY 进行数字签名,即可完成应用接入与认证授权。

您可以通过如下步骤获得 ACCESS_KEYSECRET_KEY

  1. 开通七牛开发者帐号
  2. 登录七牛开发者自助平台,查看 ACCESS_KEY 和 SECRET_KEY

获取到 ACCESS_KEYSECRET_KEY 之后,您就可以参考下面的示例代码进行接入使用了。

使用

SDK 使用文档参考:http://docs.qiniutek.com/v3/sdk/nodejs/

示例程序

var qiniu = require('qiniu');

// 配置密钥
qiniu.conf.ACCESS_KEY = '<Please apply your access key>';
qiniu.conf.SECRET_KEY = '<Dont send your secret key to anyone>';

// 实例化带授权的 HTTP Client 对象
var conn = new qiniu.digestauth.Client();

// 创建空间,也可以在开发者自助网站创建
var bucket = 'yet_another_bucket';
qiniu.rs.mkbucket(conn, bucket, function(resp) {
    console.log("\n===> Make bucket result: ", resp);
    if (resp.code != 200) {
        return;
    }
});

// 实例化 Bucket 操作对象
var rs = new qiniu.rs.Service(conn, bucket);

// 上传文件第1步
// 生成上传授权凭证(uploadToken)
var opts = {
    scope: "yet_another_bucket",
    expires: 3600,
    callbackUrl: "http://www.example.com/notifications/qiniurs", // 可选
    callbackBodyType: "application/x-www-form-urlencoded", // 可选
    customer: "username@example.com" // 可选
};
var token = new qiniu.auth.UploadToken(opts);
var uploadToken = token.generateToken();

// 上传文件第2步
// 组装上传文件所需要的参数
var key = __filename;
var localFile = key,
    customMeta = "",
    callbackParams = {"bucket": bucket, "key": key},
    enableCrc32Check = false,
    mimeType = mime.lookup(key);

// 上传文件第3步
// 上传文件
rs.uploadFileWithToken(uploadToken, localFile, key, mimeType, customMeta, callbackParams, enableCrc32Check, function(resp){
    console.log("\n===> Upload File with Token result: ", resp);
    if (resp.code != 200) {
        // ...
        return;
    }

    // 查看已上传文件属性信息
    rs.stat(key, function(resp) {
        console.log("\n===> Stat result: ", resp);
        if (resp.code != 200) {
            // ...
            return;
        }
    });
});


// 获取文件下载链接(含文件属性信息)
var saveAsFriendlyName = key;
rs.get(key, saveAsFriendlyName, function(resp) {
    console.log("\n===> Get result: ", resp);
    if (resp.code != 200) {
        // ...
        return;
    }
});

// 删除已上传文件
rs.remove(key, function(resp) {
    console.log("\n===> Delete result: ", resp);
});

// 将bucket的内容作为静态内容发布
var DEMO_DOMAIN = bucket + '.dn.qbox.me';
rs.publish(DEMO_DOMAIN, function(resp){
    console.log("\n===> Publish result: ", resp);
    if (resp.code != 200){
        clear(rs);
        return;
    }
});

// 删除bucket,慎用!
rs.drop(function(resp){
    console.log("\n===> Drop result: ", resp);
});
