Package net/http has a layered design where each layer is a convenience wrapper on top of a lower layer.

Each lower layer is more complex but offers more control.

Here’s a recap of 3 ways of doing an HTTP GET request.

Use http.Get() function

Using top-level http.Get() function is the simplest but not recommended due to lack of timeouts.

Use http.Client.Get() method

• create *http.Client with &http.Client{}
• set appropriate Timeout
• use its Get() or Post() or PostForm() methods

Use http.Client.Do() method

This allows the greatest control over the request.

• create http.Client and set apropriate Timeout
• create *http.Request with http.NewRequest
• set its Method to "GET", "POST", "HEAD", "PUT" or "DELETE"
• set custom headers like User-Agentwith Header.Set(key, value string)
• set body to be sent by setting Body of type io.ReadCloser
• set TransferEncoding
