Javascript download s3 file with basic authentication

To interact with any AWS services, Node. Then, create the main program file and data folder. In the data folder, drop any file you want. In this example, I am using a json file called data.

First of all, you need to import the aws-sdk module and create a new S3 object. Locking in API version for S3 object is optional. Here is the further document on the S3 class. For serverless user authentication with Cognito, check out the post here. This post focuses on client-side JavaScript to enable S3 uploading. The cool thing about this is that you can trigger a lambda function on S3 upload event and further do data processing, then bring back the result with another lambda function.

The possibility is endless! We can simply import aws-sdk-js in the script tag at the end of the body. However, I wanted to do this while ensuring only a few people had access to the content using their Web browsers. The browser shows its native login screen and prompts for a user name and password. After entering the login credentials, they are concatenated, Base64 encoded, and added to the next request in Authorization HTTP header. Now, the browser tries to make another attempt to fetch the same webpage.

But, this time, the HTTP request contains a header:. The above is just an example. In the example, the Base64 encoded part means joe:secret , where joe is the user name and secret the password entered by the user. The server implements authentication and authorization using a special file. Active 6 years, 3 months ago. Viewed 2k times. Improve this question. Add a comment. Active Oldest Votes.
