How to Set Custom Headers in Go's HTTP GET Requests?

Setting Headers in HTTP GET Requests with Go

In a Go program, you can customize the headers of an HTTP GET request using the Header field of the Request struct. The syntax to set a header is:

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

Example code:

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

This code sets the header with the key "X-My-Header" to the value "value". You can set multiple headers by calling Set multiple times or by using the Add method.
