How Can I Efficiently Manage Data Overload in HTTP GET Requests?

Managing Data Overload in HTTP GET Requests

When scraping vast amounts of data from multiple URLs, it becomes crucial to prevent getting bogged down by excessively large responses. Here's how to limit the amount of data read during a HTTP GET request:

Limiting Bytes Read

To control the number of bytes received, utilize an io.LimitedReader. This reader limits the data returned to a specified number of bytes. For instance:

limitedReader := &io.LimitedReader{R: response.Body, N: limit}
body, err := io.ReadAll(limitedReader)

Here, limit is the maximum number of bytes to read.

Alternatively:

body, err := io.ReadAll(io.LimitReader(response.Body, limit))

Both approaches achieve the same result by limiting the data retrieved from the server.

By setting an appropriate limit, you can ensure that your scraping operation will not get stuck with large responses, allowing you to process the data efficiently.
