3).由于请求尺寸的图片不存在,浏览器将被重定向(307)到API Gateway端点 4).API Gateway 触发Lambda 函数 5).Lambda 函数从S3 存储同下载原始图片,调整大小后,将图片上传回存储桶 6).API Gateway 重定向(301) 到新创建的CloudFront URL 流程结束。 3.具体配置简要介绍 1).S3 Bucket 创建S3Bucket,并配置策略 ...

Amazon S3 存储桶 新增文件自动触发 AWS Lambda。Lambda 取 S3 文件做转换并存回去 S3 同一个目录下,并增加相应的后缀名。 并且支持通过API Gateway的方式触发对图片进行修改并输出。 本 Lab 使用 Python Pillow 做图片转换,读者可以参考 Pillow 文档进行功能扩展。
The Lambda function downloads the original image from the S3 bucket, resizes it, and uploads the resized image back into the bucket as the originally requested key. When the Lambda function completes, API Gateway permanently redirects the user to the file stored in S3. ...

lambda_handler当我们的lambda函数被要调整大小的图像的新传入请求触发时,将调用它。它从请求路径获取key和size参数,然后它resize_image使用前面的参数和s3存储桶名称调用该函数,以便获得新调整大小的图像的位置。现在让我们深入了解我们的resize_imag...
I'm trying to resize and watermark an image (downloaded from S3) in an AWS Lambda function. The resizing part is working well, based on the sample code from the "getting started" project of AWS Lambda. Now, I have a problem adding a w
Serverless applications often consist of small units of work, such as Lambda functions that retrieve products from a database, or process items from a queue, or resize an image in storage. Each component runs in their own environment. Teams will likely be responsible for many of these small ...
