Give the function a name, such as "FileDownloadLambda" select the runtime as Python 3.9, and click on "Create function" to create the Lambda function.Įnsure that the lambda has necessary permission to download an image to S3 bucket and configure a appropriate Lambda timeout. From the options, select "Author from scratch" to create the Lambda function from scratch. To create a Lambda function for file downloading, navigate to the AWS Lambda console and click on the "Create function" button. Step 3: Create a Lambda function that will handle the file download functionality Once the file has been uploaded successfully, the function returns a response containing an HTTP status code of 200 and a JSON message saying "File uploaded successfully". The method requires the bucket name, the generated filename, and the decoded file content as input parameters. The function then decodes the file content using base64.b64decode() to get the actual bytes of the file.Īfter that, the function generates a unique filename for the uploaded file using the current timestamp and the filename format of "image_YMD_HMS.jpg".įinally, the function uploads the file to the S3 bucket using the s3.put_object() method.
This payload includes the content of the uploaded file, encoded in base64 format. Then, the function's input event is received, which is a JSON payload containing information about the upload request. The above function starts by importing necessary libraries such as json, boto3, base64, and datetime. Once the code is entered, click on "Deploy" to deploy the Lambda function.Įnsure that the lambda has necessary permission to upload an image to S3 bucket and configure a appropriate Lambda timeout. Inside the Lambda function, navigate to the "Code" tab and enter the code as shown in the image above. Give the function a name, such as "FileUploadLambda," select the runtime as Python 3.9, and click on "Create function" to create the Lambda function. To create a Lambda function for file uploading, navigate to the AWS Lambda console and click on the "Create function" button.
