How to Display an Ampersand (&) Unescaped in Go\'s JSON Response?

Handling Character Display Instead of ASCII

In the provided Go code, the goal is to display an ampersand character (&) in a JSON response. However, the current code results in the ampersand being escaped as "u0026".

To address this, we need to disable HTML escaping in the JSON encoder. In Go versions prior to 1.7, this was not possible. However, Go 1.7 introduced a new option: Encoder.DisableHTMLEscaping.

This option allows us to prevent the escaping of <, >, and & characters in JSON strings. To use this option, we need to set it on the encoder object.

enc := json.NewEncoder(os.Stdout)
enc.SetEscapeHTML(false)

Once the HTML escaping is disabled, the encoder will no longer escape the ampersand character, resulting in the desired output:

Chrome browser show:

{
    "key": "&"
}
&

Console also show:

{
    "key": "&"
}
&
