Allow Public Read access to an AWS S3 Bucket

# Allow Public Read access to an S3 Bucket To allow public read access to an S3 bucket: Open the AWS S3 console and click on the bucket’s name Click on the Permissions tab Find the Block public access (bucket settings) section, click on the Edit button, uncheck the checkboxes and click on Save changes In the Permissions tab, scroll down to the Bucket policy section and click on the Edit button. Paste the following policy into the textarea to grant public read access to all files in your S3 bucket. Replace the YOUR_BUCKET_NAME placeholder with your bucket’s name. bucket-policy-public-read { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": "*", "Action": [ "s3:GetObject" ], "Resource": "arn:aws:s3:::YOUR_BUCKET_NAME/*" } ] } For example, the bucket policy of an S3 bucket with the name my-bucket will look like: Save the changes you’ve made to the bucket’s [...x]

policy and your bucket will have public read access enabled.

(Optional) – If you need to access your bucket with HTTP requests from the browser, you have to update the bucket’s Cross-origin resource sharing (CORS) options to allow your frontend’s requests
- In the Permissions tab of your S3 bucket, scroll down to the Cross-origin resource sharing (CORS) section and click on the Edit button
- Paste the following JSON into the textarea and save the changes

cors-configuration

[
  {
      "AllowedHeaders": [
          "Authorization",
          "Content-Length"
      ],
      "AllowedMethods": [
          "GET"
      ],
      "AllowedOrigins": [
          "*"
      ],
      "ExposeHeaders": [],
      "MaxAgeSeconds": 3000
  }
]

To test that your bucket has public read access enabled:

Click on the Objects tab in your S3 bucket.
Click on the checkbox next to a file’s name.
Click on the Copy URL button at the top and copy the public URL of the file.

Paste the URL in your browser and you should see the contents of the file (for HTML files or images).

Note that you’ll see a red badge with the text Publicly accessible next to your bucket’s name.

In this case, the bucket policy only grants public read access to the bucket, so other people can’t add objects to your S3 bucket.

Either you can take query string inside Lambda like below,

var result =  event["queryStringParameters"]['queryStringParam1']

According to your API URL,

var postcode =  event["queryStringParameters"]['postcode']
var house =  event["queryStringParameters"]['house']

or you can use body mapping template in the integration request section and get request body and query strings. Construct a new JSON at body mapping template, which will have data from request body and query string. As we are adding body mapping template your business logic will get the JSON we have constructed at body mapping template.

Inside body mapping template to get query string please do ,

$input.params(‘querystringkey’)

For example inside body mapping template,

#set($inputRoot = $input.path('$'))
{
"firstName" : "$input.path('$.firstName')",
"lastName" : "$input.path('$.lastName')"
"language" : "$input.params('$.language')"
}

Run code snippet
