Jak uzyskać kod odpowiedzi HTTP za pomocą Selenium WebDriver

Napisałem testy z Selenium2 / WebDriver i chcę sprawdzić, czy żądanie HTTP zwraca HTTP 403 Forbidden.

Czy można uzyskać kod statusu odpowiedzi HTTP za pomocą Selenium WebDriver?

Jednym słowem nie. Nie jest to możliwe przy użyciu Selenium WebDriver API. Zostało to omówione do znudzenia w narzędziu do śledzenia problemów projektu, a funkcja nie zostanie dodana do interfejsu API.

Możliwe jest uzyskanie kodu odpowiedzi na żądanie http przy użyciu Selenium i Chrome lub Firefox. Wszystko, co musisz zrobić, to uruchomić przeglądarkę Chrome lub Firefox w trybie logowania. Poniżej pokażę kilka przykładów.

java + Selenium + Chrome Oto przykład java + Selenium + Chrome, ale myślę, że można to zrobić w dowolnym języku (python, c #, ...).

Wszystko, co musisz zrobić, to powiedzieć chromedriverowi, aby zrobił „Network.enable”. Można to zrobić, włączając rejestrowanie wydajności.

LoggingPreferences logPrefs = new LoggingPreferences();
logPrefs.enable(LogType.PERFORMANCE, Level.ALL);
cap.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);

Po zakończeniu żądania wystarczy pobrać i powtórzyć dzienniki wydajności i znaleźć „Network.responseReceived” dla żądanego adresu URL:

LogEntries logs = driver.manage().logs().get("performance");

Oto kod:

    status code: 200

java + Selenium + Firefox Wreszcie znalazłem również sztuczkę dla Firefoksa. Trzeba zacząć firefox użyciu MOZ_LOGi MOZ_LOG_FILEzmienne środowisko i zalogować http żądania na poziomie debugowania (4 = PR_LOG_DEBUG) - map.put("MOZ_LOG", "timestamp,sync,nsHttp:4"). Zapisz dziennik w pliku tymczasowym. Następnie pobierz zawartość zapisanego pliku dziennika i przeanalizuj go pod kątem kodu odpowiedzi (używając kilku prostych wyrażeń regularnych). Najpierw wykryj początek żądania, określając jego identyfikator (nsHttpChannel::BeginConnect [this=000000CED8094000]), a następnie w drugim kroku znajdź kod odpowiedzi dla tego identyfikatora żądania (nsHttpChannel::ProcessResponse [this=000000CED8094000 httpStatus=200]).

Możesz użyć serwera proxy BrowserMob do przechwytywania żądań i odpowiedzi za pomocą pliku HttpRequestInterceptor. Oto przykład w Javie:

// Start the BrowserMob proxy
ProxyServer server = new ProxyServer(9978);
server.start();

server.addResponseInterceptor(new HttpResponseInterceptor()
{
    @Override
    public void process(HttpResponse response, HttpContext context)
        throws HttpException, IOException
    {
        System.out.println(response.getStatusLine());
    }
});

// Get selenium proxy
Proxy proxy = server.seleniumProxy();

// Configure desired capability for using proxy server with WebDriver
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.PROXY, proxy);

// Set up driver
WebDriver driver = new FirefoxDriver(capabilities);

driver.get("http://stackoverflow.com/questions/6509628/webdriver-get-http-response-code");

// Close the browser
driver.quit();

Dla osób używających Pythona możesz rozważyć Selenium Wire , bibliotekę, którą opracowałem do sprawdzania żądań wysyłanych przez przeglądarkę podczas testu.

Dostęp do żądań uzyskujesz poprzez driver.requestsatrybut:

from seleniumwire import webdriver  # Import from seleniumwire

# Create a new instance of the Firefox driver
driver = webdriver.Firefox()

# Go to the Google home page
driver.get('https://www.google.com')

# Access requests via the `requests` attribute
for request in driver.requests:
    if request.response:
        print(
            request.url,
            request.response.status_code,
            request.response.headers['Content-Type']
        )

Biblioteka daje możliwość dostępu do nagłówków, kodu statusu, treści, a także możliwość modyfikowania nagłówków i przepisywania adresów URL.

Miałem również ten sam problem i utknąłem na kilka dni, ale po kilku badaniach doszedłem do wniosku, że możemy faktycznie użyć "--remote-port-debugowania" przeglądarki Chrome do przechwytywania żądań w połączeniu ze sterownikiem sieciowym selenu. Użyj następującego pseudokodu jako odniesienia: -

utworzyć instancję sterownika Chrome ze zdalnym debugowaniem

int freePort = findFreePort();

chromeOptions.addArguments("--remote-debugging-port=" + freePort);

ChromeDriver driver = new ChromeDriver(chromeOptions);`

zadzwoń pod numer http://127.0.0.1:freePort

String response = makeGetCall( "http://127.0.0.1" + freePort  + "/json" );

Wyodrębnij adres URL webSocket przeglądarki Chrome, aby nasłuchiwać, możesz zobaczyć odpowiedź i dowiedzieć się, jak wyodrębnić

String webSocketUrl = response.substring(response.indexOf("ws://127.0.0.1"), response.length() - 4);

Podłącz do tego gniazda, możesz użyć asyncHttp

socket = maketSocketConnection( webSocketUrl );

Włącz przechwytywanie sieci

socket.send( { "id" : 1, "method" : "Network.enable" } );

Teraz Chrome wyśle ​​wszystkie zdarzenia związane z siecią i przechwyci je w następujący sposób

socket.onMessageReceived( String message ){

    Json responseJson = toJson(message);
    if( responseJson.method == "Network.responseReceived" ){
       //extract status code
    }
}

driver.get("http://stackoverflow.com");

możesz zrobić wszystko, o czym mowa w witrynie narzędzi programistycznych. patrz https://chromedevtools.github.io/devtools-protocol/ Uwaga: - użyj chromedriver 2.39 lub nowszego.

Mam nadzieję, że to komuś pomoże.

Uzyskaj kod odpowiedzi w dowolnym języku (używając JavaScript):

Jeśli Twoje testy Selenium są uruchamiane w nowoczesnej przeglądarce, prostym sposobem uzyskania kodu odpowiedzi jest wysłanie synchronicznego XMLHttpRequest* i sprawdzenie statusodpowiedzi:

var xhr = new XMLHttpRequest();
xhr.open('GET', 'http://exampleurl.ex', false);
xhr.send(null);

assert(200, xhr.status);

Możesz użyć tej techniki z dowolnym językiem programowania, żądając, aby Selenium wykonało skrypt. Na przykład w Javie możesz JavascriptExecutor.executeScript()wysłać XMLHttpRequest:

final String GET_RESPONSE_CODE_SCRIPT =
    "var xhr = new XMLHttpRequest();" +
    "xhr.open('GET', arguments[0], false);" +
    "xhr.send(null);" +
    "return xhr.status";
JavascriptExecutor javascriptExecutor = (JavascriptExecutor) webDriver;
Assert.assertEquals(200,
    javascriptExecutor.executeScript(GET_RESPONSE_CODE_SCRIPT, "http://exampleurl.ex"));

* Zamiast tego możesz wysłać asynchroniczny XMLHttpRequest, ale przed kontynuowaniem testu musisz poczekać na jego zakończenie.

Uzyskaj kod odpowiedzi w języku Java:

Kod odpowiedzi w języku Java można uzyskać za pomocą URL.openConnection()i HttpURLConnection.getResponseCode():

URL url = new URL("http://exampleurl.ex");
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setRequestMethod("GET");

// You may need to copy over the cookies that Selenium has in order
// to imitate the Selenium user (for example if you are testing a
// website that requires a sign-in).
Set<Cookie> cookies = webDriver.manage().getCookies();
String cookieString = "";

for (Cookie cookie : cookies) {
    cookieString += cookie.getName() + "=" + cookie.getValue() + ";";
}

httpURLConnection.addRequestProperty("Cookie", cookieString);
Assert.assertEquals(200, httpURLConnection.getResponseCode());

Ta metoda prawdopodobnie mogłaby zostać uogólniona również na inne języki, ale musiałaby zostać zmodyfikowana, aby pasowała do API języka (lub biblioteki).

Nie jestem pewien, czego szukasz, ale miałem trochę inny cel, to sprawdzić, czy zdalny obraz istnieje i nie będę miał błędu 403, więc możesz użyć czegoś takiego poniżej:

public static boolean linkExists(String URLName){
    try {
        HttpURLConnection.setFollowRedirects(false);
        HttpURLConnection con = (HttpURLConnection) new URL(URLName).openConnection();
        con.setRequestMethod("HEAD");
        return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
    }
    catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}

Nie jest możliwe uzyskanie kodu odpowiedzi HTTP bezpośrednio przy użyciu Selenium WebDriver. Kod można uzyskać za pomocą kodu Java i można go używać w Selenium WebDriver.

Aby uzyskać kod odpowiedzi HTTP przez java:

public static int getResponseCode(String urlString) throws MalformedURLException, IOException{
    URL url = new URL(urlString);
    HttpURLConnection huc = (HttpURLConnection)url.openConnection();
    huc.setRequestMethod("GET");
    huc.connect();
    return huc.getResponseCode();
}

Teraz możesz napisać swój kod Selenium WebDriver, jak poniżej:

private static int statusCode;
public static void main(String... args) throws IOException{
    WebDriver driver = new FirefoxDriver();
    driver.manage().window().maximize();
    driver.get("https://www.google.com/");
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

    List<WebElement> links = driver.findElements(By.tagName("a"));
    for(int i = 0; i < links.size(); i++){
        if(!(links.get(i).getAttribute("href") == null) && !(links.get(i).getAttribute("href").equals(""))){
            if(links.get(i).getAttribute("href").contains("http")){
                statusCode= getResponseCode(links.get(i).getAttribute("href").trim());
                if(statusCode == 403){
                    System.out.println("HTTP 403 Forbidden # " + i + " " + links.get(i).getAttribute("href"));
                }
            }
        }   
    }   
}

Możesz wypróbować Mobilenium ( https://github.com/rafpyprog/Mobilenium ), pakiet Pythona, który wiąże BrowserMob Proxy i Selenium.

Przykład użycia:

>>> from mobilenium import mobidriver
>>>
>>> browsermob_path = 'path/to/browsermob-proxy'
>>> mob = mobidriver.Firefox(browsermob_binary=browsermob_path)
>>> mob.get('http://python-requests.org')
301
>>> mob.response['redirectURL']
'http://docs.python-requests.org'
>>> mob.headers['Content-Type']
'application/json; charset=utf8'
>>> mob.title
'Requests: HTTP for Humans \u2014 Requests 2.13.0 documentation'
>>> mob.find_elements_by_tag_name('strong')[1].text
'Behold, the power of Requests'
