How Can I Limit Data Consumption in HTTP GET Requests for Web Scraping?

Limiting Data Reception in HTTP GET Requests

When scraping HTML pages, it is crucial to prevent GET requests from consuming excessive data and stalling the process.

To control the volume of data received from a given resource, consider utilizing an io.LimitedReader. This reader effectively restricts the data read from a source to a specified limit.

// io.LimitedReader limits the number of bytes returned
limitedReader := &io.LimitedReader{R: response.Body, N: limit}
body, err := io.ReadAll(limitedReader)

An alternative approach is to employ io.LimitReader directly:

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

By incorporating either the io.LimitedReader or io.LimitReader method into your request handling code, you can establish a maximum data intake threshold, ensuring that excessive responses do not hinder your scraping efficiency.
