Create a new client

To start making requests you need the API Key. You can find it on your profile page on whoisxmlapi.com. Using the API Key you can create Client.

Most users will be fine with NewBasicClient function.

client := screenshotapi.NewBasicClient(apiKey)

If you want to set custom http.Client to use proxy then you can use NewClient function.

transport := &http.Transport{Proxy: http.ProxyURL(proxyUrl)}

client := screenshotapi.NewClient(apiKey, screenshotapi.ClientParams{
    HTTPClient: &http.Client{
        Transport: transport,
        Timeout:   20 * time.Second,
    },
})

Make basic requests

Screenshot API lets you get a screenshot of any web page as a jpg, png or pdf file.

// Take a screenshot of the specified URL and save it to the file.
err := client.Get(ctx, "whoisxmlapi.com", "filename.jpg")
if err != nil {
    log.Fatal(err)
}

Advanced usage

cookies := screenshotapi.Cookies{
    "name1": "value1",
    "name2": "value2",
}

// Get raw API response with the following options:
// Pass cookies, emulate mobile device, disable JS, wait for network idle
// event, output API errors in XML, capture PDF screenshot in full page
// mode and get image data in base64.
resp, err := client.GetRaw(ctx,
    "whoisxmlapi.com",
    screenshotapi.OptionType("pdf"),
    screenshotapi.OptionMode("slow"),
    screenshotapi.OptionFullPage(true),
    screenshotapi.OptionMobile(true),
    screenshotapi.OptionErrorsOutputFormat("JSON"),
    screenshotapi.OptionImageOutputFormat("base64"),
    screenshotapi.OptionNoJs(true),
    screenshotapi.OptionCookies(cookies))

if err != nil {
    log.Fatal(err)
}

// body contains base64-encoded pdf file,
// either json with error message on failure
_ = resp.Body
