How Can I Customize Timeouts for HTTP GET Requests in Golang?

Customizing Timeouts for HTTP GET Requests in Golang

When working with URL fetchers, controlling the timeout of HTTP GET requests is essential to optimize performance. By default, these requests have a long timeout, which can significantly slow down your program. Here's how you can set a custom timeout for each HTTP GET request in Golang:

Solution:

In Golang version 1.3 and later, the http.Client struct offers a Timeout field that allows you to specify a timeout duration. Here's an example:

import (
    "net/http"
    "time"
)

client := http.Client{
    Timeout: 40 * time.Second,
}

resp, fetch_err := client.Get(url)

By setting the Timeout field to 40 * time.Second, the HTTP GET request will time out after 40 seconds. If the request exceeds this timeout, it will return an error with the message "request timed out." This allows your URL fetcher to proceed to the next URL without being held up by slow responses.
