It can receive, filter and encapsulate the pictures in multipart / form data requests, which is convenient for business processing. Then today's protagonist, Multer middleware, can help us meet these requirements. In fact, we prefer to accept and cache the uploaded file before entering the request processing, and encapsulate the information about it in an object for subsequent operations. The file sent by http request will arrive at the server through the network in the form of binary stream, but it is obviously inconvenient to deal with it directly, especially when a request contains multiple files and other parameters. Postman simplifies each step of the API lifecycle and streamlines collaboration so you can create better APIsfaster.

Now the work is done to upload an image to S3. const AWS = require('aws-sdk') //*/ get reference to S3 client var s3 = new AWS.S3() exports.handler = (event, context, callback) => Since the request body is a Base64 string, we have to decode it back and upload to S3.įollowing is my script for uploading the image to S3 bucket.
