How to Customize HTTP GET Request Headers in Go?

Customizing Request Headers in HTTP GET Requests in Go

In Go, when performing an HTTP GET request using the standard library's http package, it is possible to set custom headers for the request. Here's how you can do this:

The http package provides a Header field in the Request struct, which allows you to add, modify, and retrieve headers associated with the request. To set a header, you can use the Set method, as shown in the example below:

client := &http.Client{}
req, _ := http.NewRequest("GET", url, nil)
req.Header.Set("name", "value")
res, _ := client.Do(req)

In this example, a custom header named "name" is set to the value "value." The request is then executed using the Do method of the http.Client.

You can set multiple headers by repeatedly using the Set method. For instance, the following code sets two headers:

req.Header.Set("name", "value")
req.Header.Set("another-header", "another-value")

The Header field is a map of string keys and string values. You can use the Get method to retrieve the value of an existing header:

value := req.Header.Get("name")

To remove a header, you can use the Del method:

req.Header.Del("name")
