Come ottenere il codice di risposta HTTP utilizzando Selenium WebDriver

Ho scritto test con Selenium2 / WebDriver e voglio verificare se la richiesta HTTP restituisce un HTTP 403 Forbidden.

È possibile ottenere il codice di stato della risposta HTTP con Selenium WebDriver?

In una parola no. Non è possibile utilizzare l'API Selenium WebDriver. Questo è stato discusso fino alla nausea nel tracker dei problemi per il progetto e la funzionalità non verrà aggiunta all'API.

È possibile ottenere il codice di risposta a una richiesta http utilizzando Selenium e Chrome o Firefox. Tutto quello che devi fare è avviare Chrome o Firefox in modalità di registrazione. Ti mostrerò alcuni esempi di seguito.

java + Selenium + Chrome Ecco un esempio di java + Selenium + Chrome, ma immagino che possa essere fatto in qualsiasi lingua (python, c #, ...).

Tutto quello che devi fare è dire a chromedriver di fare "Network.enable". Questo può essere fatto abilitando la registrazione delle prestazioni.

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

Dopo che la richiesta è stata eseguita, tutto ciò che devi fare è ottenere e iterare i log di Perfomance e trovare "Network.responseReceived" per l'URL richiesto:

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

Ecco il codice:

    status code: 200

java + Selenium + Firefox Ho finalmente trovato il trucco anche per Firefox. È necessario avviare Firefox utilizzando le variabili di ambiente MOZ_LOGe MOZ_LOG_FILEe registrare le richieste http a livello di debug (4 = PR_LOG_DEBUG) - map.put("MOZ_LOG", "timestamp,sync,nsHttp:4"). Salva il registro in un file temporaneo. Successivamente, ottenere il contenuto del file di registro salvato e analizzarlo per il codice di risposta (utilizzando alcune semplici espressioni regolari). Per prima cosa rileva l'inizio della richiesta, identificandone l'ID (nsHttpChannel::BeginConnect [this=000000CED8094000]), quindi al secondo passaggio, trova il codice di risposta per quell'ID richiesta (nsHttpChannel::ProcessResponse [this=000000CED8094000 httpStatus=200]).

È possibile utilizzare il proxy BrowserMob per acquisire le richieste e le risposte con un file HttpRequestInterceptor. Ecco un esempio in Java:

// 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();

Per coloro che utilizzano Python, potresti prendere in considerazione Selenium Wire , una libreria che ho sviluppato per ispezionare le richieste fatte dal browser durante un test.

Puoi accedere alle richieste tramite l' driver.requestsattributo:

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']
        )

La libreria ti dà la possibilità di accedere a intestazioni, codice di stato, contenuto del corpo, nonché la possibilità di modificare intestazioni e riscrivere URL.

Ho anche avuto lo stesso problema e sono rimasto bloccato per alcuni giorni, ma dopo alcune ricerche ho capito che possiamo effettivamente usare "--remote-debugging-port" di chrome per intercettare le richieste insieme al driver web selenium. Usa il seguente pseudocodice come riferimento: -

crea istanza del driver chrome con debug remoto

int freePort = findFreePort();

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

ChromeDriver driver = new ChromeDriver(chromeOptions);`

effettua una chiamata a http://127.0.0.1:freePort

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

Estrai l'URL webSocket di Chrome per ascoltare, puoi vedere la risposta e capire come estrarre

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

Connettiti a questa presa, puoi usare asyncHttp

socket = maketSocketConnection( webSocketUrl );

Abilita l'acquisizione in rete

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

Ora chrome invierà tutti gli eventi relativi alla rete e li acquisirà come segue

socket.onMessageReceived( String message ){

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

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

puoi fare tutto ciò che è menzionato nel sito degli strumenti di sviluppo. vedere https://chromedevtools.github.io/devtools-protocol/ Nota: - usa chromedriver 2.39 o successivo.

Spero che aiuti qualcuno.

riferimento: utilizzo del protocollo di debug remoto di Google Chrome

Ottieni il codice di risposta in qualsiasi lingua (utilizzando JavaScript):

Se i tuoi test Selenium vengono eseguiti in un browser moderno, un modo semplice per ottenere il codice di risposta è inviare un sincrono XMLHttpRequest* e controllare statusla risposta:

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

assert(200, xhr.status);

È possibile utilizzare questa tecnica con qualsiasi linguaggio di programmazione richiedendo a Selenium di eseguire lo script. Ad esempio, in Java puoi usare JavascriptExecutor.executeScript()per inviare 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"));

* Puoi inviare un file asincrono XMLHttpRequest invece , ma dovrai attendere che venga completato prima di continuare il test.

Ottieni il codice di risposta in Java:

È possibile ottenere il codice di risposta in Java utilizzando URL.openConnection()e 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());

Questo metodo potrebbe probabilmente essere generalizzato anche ad altri linguaggi, ma dovrebbe essere modificato per adattarsi all'API del linguaggio (o della libreria).

Non sono sicuro che questo sia quello che stai cercando, ma avevo un obiettivo un po 'diverso è controllare se esiste un'immagine remota e non avrò l'errore 403, quindi potresti usare qualcosa come di seguito:

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;
    }
}

Non è possibile ottenere il codice di risposta HTTP utilizzando Selenium WebDriver direttamente. Il codice può essere ottenuto utilizzando il codice Java e può essere utilizzato in Selenium WebDriver.

Per ottenere il codice di risposta HTTP da 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();
}

Ora puoi scrivere il tuo codice Selenium WebDriver come di seguito:

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"));
                }
            }
        }   
    }   
}

Potresti provare Mobilenium ( https://github.com/rafpyprog/Mobilenium ), un pacchetto python che lega BrowserMob Proxy e Selenium.

Un esempio di utilizzo:

>>> 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'
