GoQuery Response Code

In GoQuery, if I create a snippet as follows: 

    doc, err := goquery.NewDocument(s)
    if err != nil {
        log.Fatal(err)
    }

where s is a valid url, I can see the error string, but if the page is returning a 403, how do I find out and stop instead of letting my code run?

Is there a way to find the http response using Goquery?

Solution

  • I don't think that NewDocument gives you the chance to bail based on a status code, but you can use NewDocumentFromResponse instead. E.g.:

    res, err := http.Get(url)
if err != nil {
    log.Fatal(err)
}

// Check for a 200 status (or a non-403, or whatever you want)
if res.StatusCode == 200 {
    doc, err := goquery.NewDocumentFromResponse(res)
    if err != nil {
        log.Fatal(err)
    }
    // ...
}
