The go language adds custom http header methods when requesting http

This example shows how the go language adds custom http header to request http. Share with you for your reference. The specific implementation method is as follows:

client := &http.Client{]

req, err := http.NewRequest("POST", "http://example.com", bytes.NewReader(postData))

req.Header.Add("User-Agent", "myClient")

resp, err := client.Do(req)

defer resp.Body.Close()

I hope this article has been helpful to your programming of Go language.
