How Can I Easily Convert an HTTP Response Body to a String in Go?

Accessing HTTP Response as a String in Go

When retrieving web requests in Go, accessing the response as a string can sometimes be challenging. Despite your best efforts, accessing the response as a string might prove difficult. This article explores a common issue: obtaining the response body as a string, and provides a solution using the string() function.

A common approach to retrieving the response body is demonstrated in the code snippet you provided. However, accessing the response as a string directly from resp.Body using a simple loop like for i:= 0; i < len(body); i { fmt.Println( body[i] ) } will print numbers representing ASCII values rather than the desired string.

To convert the response body into a string, you can use the string() function as follows:

bs := string(body)

This line will convert the byte array body into a string, which you can then use as a regular string. The variable bs now holds the response body as a string, allowing you to perform string operations on it.

For further illustration, here's a modified version of your code snippet that uses string() to obtain the response body as a string:

func main() {
    resp, err := http.Get("http://google.hu/")
    if err != nil {
        // handle error
    }
    defer resp.Body.Close()
    body, err := ioutil.ReadAll(resp.Body)

    bs := string(body) // Converts the response body into a string

    fmt.Println(bs) // Log the string representation of the response body
    fmt.Println("done")
}

In this updated code, the variable bs contains the response body as a string, which is then logged using fmt.Println(bs). Running this modified code will print the string representation of the HTTP response.
