Getting the status code from a get request in golang-CodePudding

I'm trying to get the http status code in goland.

I'm passing the authorization token as well.

This is what I tried so far:

func StatusCode(PAGE string, AUTH string) (r string){

    resp, err := http.NewRequest("GET", PAGE, nil)
    if err != nil {
        log.Fatal(err)
    }
    resp.Header.Set("Authorization", AUTH)

    fmt.Println("HTTP Response Status:", resp.StatusCode, http.StatusText(resp.StatusCode))

    r := resp.StatusCode   http.StatusText(resp.StatusCode)
}

Basically I want to get this:

r = "200 OK"
or
r= "400 Bad request"

The previous code it´s complaining from resp.StatusCode and http.StatusText(resp.StatusCode)

CodePudding user response：

There are two problems. The first is that the application uses the request as the response. Execute the request to get the response.

The second problem is that resp.StatusCode http.StatusText(resp.StatusCode) does not compile because operand types are mismatched. The value resp.StatusCode is an int. The value of http.StatusText(resp.StatusCode) is a string. Go does not have the implicit conversion of numbers to strings that would make this work the way you expect.

Use r := resp.Status if you want the status string as sent from the server.

Use r := fmt.Sprintf("%d %s", resp.StatusCode, http.StatusText(resp.StatusCode)) to construct a status string from the server's status code and the Go's status strings.

Here's the code:

func StatusCode(PAGE string, AUTH string) (r string) {
    // Setup the request.
    req, err := http.NewRequest("GET", PAGE, nil)
    if err != nil {
        log.Fatal(err)
    }
    req.Header.Set("Authorization", AUTH)

    // Execute the request.
    resp, err := http.DefaultClient.Do(req)
    if err != nil {
        return err.Error()
    }
    
    // Close response body as required.
    defer resp.Body.Close()

    fmt.Println("HTTP Response Status:", resp.StatusCode, http.StatusText(resp.StatusCode))

    return resp.Status
    // or fmt.Sprintf("%d %s", resp.StatusCode, http.StatusText(resp.StatusCode))
}
