S3是亚马逊云存储服务,可以用于存储和检索各种类型的文件,包括.xlsx文件。在使用Node.js Lambda从S3上的.xlsx文件读取数据时,可以按照以下步骤进行: 创建Lambda函数:在腾讯云控制台中,创建一个新的Lambda函数,并选择Node.js作为运行时环境。 配置触发器:将S3存储桶配置为Lambda函数的触发器,以便在.xlsx文件上...

SQS触发器Lambda是一种通过使用SQS(简单队列服务)触发AWS Lambda函数的机制。它允许开发人员将消息从SQS队列中发送到Lambda函数进行处理。在S3中使用FileName进行文本提...

具体逻辑实现,首先 S3 通知触发 Lambda 函数 ”Main”,调用 S3 Head Object 获得 S3 对象大小,每个5MB分块触发一个 Lambda “MPU” (Multi Part Upload) 函数,并且生成一个中国区 S3 Upload Id 。每个 MPU 函数使用 Get Object 下载自己对应的 S3 range 部分,并调用 Upload Part 上传到中国区 S3 ,完成之后...
getObjectContext的欄位意指連線至 Amazon S3 和 S3 Object Lambda 的輸入和輸出詳細資訊。其欄位如下: inputS3Url– Lambda 函數可用來從支援存取點下載原始物件的預先簽章 URL。透過使用預先簽章的 URL,Lambda 函數不需要具有 Amazon S3 讀取許可,即可擷取原始物件,而且只能存取每次調用時處理的物件。
