Golang : Convert(cast) io.Reader type to string




Problem :

You have input of type io.Reader and you need to convert the input to string type.

Solution :

First, create a buffer and use the buffer's ReadFrom() function to read/parse the io.Reader input. Next, assign the buffer's string value to a string variable.

For example :

 // convert io.Reader type to string

 var msg io.Reader 
 ... 
 buffer := new(bytes.Buffer)
 buffer.ReadFrom(msg.Body)
 str := buffer.String()
 fmt.Println(str)
