Navigate to the S3 console, and open the S3 bucket created by the deployment.

You see a 200 OK response after the file is uploaded.

Choose Select file and choose a JPG file to upload.Ĭhoose Send.

Choose the Body tab, then the binary radio button.

Paste the URL into the Enter request URL box.

Using the dropdown, change the method from GET to PUT.

Select the + icon next to the tabs to create a new request.

The uploadURL attribute contains the signed URL.

After the request is complete, the Body section shows a JSON response.

In the Postman interface, paste the API endpoint into the box labeled Enter request URL.

First, copy the API endpoint from the output of the deployment.

The second is with a basic frontend application that demonstrates how to integrate the API. The first is with Postman, which allows you to directly call the API and upload a binary file with the signed URL. I show two ways to test this application. The upload URL is the API endpoint with /uploads appended. Once the deployment is complete, note the APIendpoint output.The API endpoint value is the base URL.

At the prompts, enter s3uploader for Stack Name and select your preferred Region.

Navigate to the S3 uploader repo and install the prerequisites listed in the README.md.To deploy the S3 uploader example in your AWS account: Directly upload the file from the application to the S3 bucket.

This gets a signed URL from the S3 bucket. Call an Amazon API Gateway endpoint, which invokes the getSignedURL Lambda function.This is two-step process for your application front end: You can then upload directly using the signed URL. When you upload directly to an S3 bucket, you must first request a signed URL from the Amazon S3 service.

You can download the code from this blog post in this GitHub repo. This pattern is used in the Happy Path web application. In this blog post, I walk through how to implement serverless uploads and show the benefits of this approach. S3 also is highly available and durable, making it an ideal persistent store for user uploads. This can significantly reduce network traffic and server CPU usage, and enable your application server to handle other requests during busy periods. If thousands of users attempt to upload media around the same time, this requires you to scale out the application server and ensure that there is sufficient network bandwidth available.īy directly uploading these files to Amazon S3, you can avoid proxying these requests through your application server.

For example, in a web application that specializes in sending holiday greetings, it may experience most traffic only around holidays.

This is challenging for applications with spiky traffic patterns. You must also manage the state of the transfer to ensure that the entire object is successfully uploaded, and manage retries and errors. Media uploads are typically large, so transferring these can represent a large share of network I/O and server CPU time. While the process is simple, it can have significant side-effects on the performance of the web-server in busier applications.

The application transfers the file to a database, file server, or object store for persistent storage.

The application server saves the upload to a temporary space for processing.

The user uploads the file to the application server.

Typically, in the server-based environment, the process follows this flow: Every modern web server technology has mechanisms to allow this functionality. Your application may allow users to upload PDFs and documents, or media such as photos or videos. In web and mobile applications, it’s common to provide users with the ability to upload data.
