Convert io.ReadCloser to a String
· 97 words · 1 minute read
Net/http is an amazing package but there are times you need to work with the response of call you have just made. Many functions require a string as input so we have to convert it first by passing it through a buffer.
package main
import (
"fmt"
"net/http"
"bytes"
)
func main() {
response, _ := http.Get("https://golangcode.com/")
// This would fail because Body = io.ReadCloser
// fmt.Printf(response.Body)
// ...so we convert it to a string by passing it through
// a buffer first. A 'costly' but useful process.
buf := new(bytes.Buffer)
buf.ReadFrom(response.Body)
newStr := buf.String()
fmt.Printf(newStr)
}
