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)
