PhotographyGo’s json.Marshal and json.MarshalIndent functions both escape HTML data.
This may be useful for some circumstances when it is being output in a browser but it is not useful when your programs expects data without escaping.
Here are a couple of functions that Marshal JSON data without escaping HTML characters.
JSON_Marshal
func JSON_Marshal(input interface{}) ([]byte, error) {
//------------------------------------------------------------
var err error
var encodeBuffer bytes.Buffer
//------------------------------------------------------------
encoder := json.NewEncoder(&encodeBuffer)
encoder.SetEscapeHTML(false)
//------------------------------------------------------------
err = encoder.Encode(input)
if err != nil {
return nil, err
}
//------------------------------------------------------------
return bytes.TrimRight(encodeBuffer.Bytes(), "\n"), err
//------------------------------------------------------------
}
JSON_MarshalIndent
func JSON_MarshalIndent(input interface{}, prefix string, indent string) ([]byte, error) {
//------------------------------------------------------------
var err error
var encodeBuffer bytes.Buffer
var indentBuffer bytes.Buffer
//------------------------------------------------------------
encoder := json.NewEncoder(&encodeBuffer)
encoder.SetEscapeHTML(false)
//------------------------------------------------------------
err = encoder.Encode(input)
if err != nil {
return nil, err
}
//------------------------------------------------------------
err = json.Indent(&indentBuffer, bytes.TrimRight(encodeBuffer.Bytes(), "\n"), prefix, indent)
if err != nil {
return nil, err
}
//------------------------------------------------------------
return indentBuffer.Bytes(), err
//------------------------------------------------------------
}
