加密示例(Node.js SDK)
开发过程中,您有任何问题可以在github上提交issue,或者在华为云对象存储服务论坛中发帖求助。
代码示例一:上传对象加密
本示例使用SSE-C方式加密上传example/objectname到examplebucket桶中。
// 引入obs库 // 使用npm安装 const ObsClient = require("esdk-obs-nodejs"); // 使用源码安装 // var ObsClient = require('./lib/obs'); // 创建ObsClient实例 const obsClient = new ObsClient({ // 推荐通过环境变量获取AKSK,这里也可以使用其他外部引入方式传入,如果使用硬编码可能会存在泄露风险 // 您可以登录访问管理控制台获取访问密钥AK/SK,获取方式请参见https://support.huaweicloud.com/usermanual-ca/ca_01_0003.html access_key_id: process.env.ACCESS_KEY_ID, secret_access_key: process.env.SECRET_ACCESS_KEY, // 【可选】如果使用临时AK/SK和SecurityToken访问OBS,同样建议您尽量避免使用硬编码,以降低信息泄露风险。您可以通过环境变量获取访问密钥AK/SK,也可以使用其他外部引入方式传入 // security_token: process.env.SECURITY_TOKEN, // endpoint填写Bucket对应的Endpoint, 这里以华北-北京四为例,其他地区请按实际情况填写 server: "https://obs.cn-north-4.myhuaweicloud.com", }); async function putObject() { try { const params = { // 指定存储桶名称 Bucket: "examplebucket", // 指定对象名,此处以 example/objectname 为例 Key: "example/objectname", // 指定文本对象 Body : 'Hello OBS', // 设置SSE-C算法加密对象 SseC: 'AES256', SseCKey: 'your sse-c key generated by AES-256 algorithm' }; // 加密上传对象 const result = await obsClient.putObject(params); if (result.CommonMsg.Status <= 300) { console.log("Put object(%s) under the bucket(%s) successful!", params.Bucket); console.log("RequestId: %s", result.CommonMsg.RequestId); return; }; console.log("An ObsError was found, which means your request sent to OBS was rejected with an error response."); console.log("Status: %d", result.CommonMsg.Status); console.log("Code: %s", result.CommonMsg.Code); console.log("Message: %s", result.CommonMsg.Message); console.log("RequestId: %s", result.CommonMsg.RequestId); } catch (error) { console.log("An Exception was found, which means the client encountered an internal problem when attempting to communicate with OBS, for example, the client was unable to access the network."); console.log(error); }; }; putObject();
代码示例二:下载对象解密
本示例用于流式下载examplebucket桶中的example/objectname加密对象。
// 引入obs库 // 使用npm安装 const ObsClient = require("esdk-obs-nodejs"); // 使用源码安装 // var ObsClient = require('./lib/obs'); // 创建ObsClient实例 const obsClient = new ObsClient({ // 推荐通过环境变量获取AKSK,这里也可以使用其他外部引入方式传入,如果使用硬编码可能会存在泄露风险 // 您可以登录访问管理控制台获取访问密钥AK/SK,获取方式请参见https://support.huaweicloud.com/usermanual-ca/ca_01_0003.html access_key_id: process.env.ACCESS_KEY_ID, secret_access_key: process.env.SECRET_ACCESS_KEY, // 【可选】如果使用临时AK/SK和SecurityToken访问OBS,同样建议您尽量避免使用硬编码,以降低信息泄露风险。您可以通过环境变量获取访问密钥AK/SK,也可以使用其他外部引入方式传入 // security_token: process.env.SECURITY_TOKEN, // endpoint填写Bucket对应的Endpoint, 这里以华北-北京四为例,其他地区请按实际情况填写 server: "https://obs.cn-north-4.myhuaweicloud.com", }); async function getObject() { try { const params = { // 指定存储桶名称 Bucket: "examplebucket", // 指定对象名,此处以 example/objectname 为例 Key: 'example/objectname', // 设置SSE-C算法解密对象 SseC: 'AES256', // 此处的密钥必须和上传对象加密时使用的密钥一致 SseCKey: 'your sse-c key generated by AES-256 algorithm' }; // 下载加密对象 const result = await obsClient.getObject(params); if (result.CommonMsg.Status <= 300) { console.log("Get object(%s) under the bucket(%s) successful!", params.Key, params.Bucket); console.log("RequestId: %s", result.CommonMsg.RequestId); console.log('Object Content: %s', result.InterfaceResult.Content); return; }; console.log("An ObsError was found, which means your request sent to OBS was rejected with an error response."); console.log("Status: %d", result.CommonMsg.Status); console.log("Code: %s", result.CommonMsg.Code); console.log("Message: %s", result.CommonMsg.Message); console.log("RequestId: %s", result.CommonMsg.RequestId); } catch (error) { console.log("An Exception was found, which means the client encountered an internal problem when attempting to communicate with OBS, for example, the client was unable to access the network."); console.log(error); }; }; getObject();
