How Can I Restrict Data Consumption in HTTP GET Requests When Scraping Web Pages?

Restricting Data Consumption in HTTP GET Requests

When scraping HTML pages, it can be beneficial to limit the amount of data received in HTTP GET requests to avoid potential bottlenecks. This is especially important when dealing with URLs that deliver excessive data.

To achieve this, consider utilizing an io.LimitedReader or io.LimitReader. These tools enable you to control the maximum number of bytes read from a response.

Using io.LimitedReader:

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

Using io.LimitReader:

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

By setting the limit parameter, you can specify the maximum byte size to be read. This prevents the GET request from consuming excessive data and helps streamline your scraping process.
