Cara mendapatkan Kode Respon HTTP menggunakan Selenium WebDriver

Saya telah menulis tes dengan Selenium2 / WebDriver dan ingin menguji apakah Permintaan HTTP mengembalikan HTTP 403 Terlarang.

Apakah mungkin mendapatkan kode status tanggapan HTTP dengan Selenium WebDriver?

Singkatnya, tidak. Ini tidak mungkin menggunakan API WebDriver Selenium. Hal ini telah dibahas selama beberapa saat di pelacak masalah untuk proyek tersebut, dan fitur tersebut tidak akan ditambahkan ke API.

Dimungkinkan untuk mendapatkan kode respon dari permintaan http menggunakan Selenium dan Chrome atau Firefox. Yang harus Anda lakukan adalah memulai Chrome atau Firefox dalam mode logging. Saya akan menunjukkan beberapa contoh di bawah ini.

java + Selenium + Chrome Berikut adalah contoh java + Selenium + Chrome, tapi saya rasa itu bisa dilakukan dalam bahasa apa pun (python, c #, ...).

Yang perlu Anda lakukan adalah memberi tahu chromedriver untuk melakukan "Network.enable". Ini dapat dilakukan dengan mengaktifkan pencatatan kinerja.

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

Setelah permintaan selesai, yang harus Anda lakukan adalah mendapatkan dan mengulangi log Performa dan menemukan "Network.responseReceived" untuk url yang diminta:

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

Ini kodenya:

    status code: 200

java + Selenium + Firefox Akhirnya saya menemukan trik untuk Firefox juga. Anda perlu memulai firefox menggunakan variabel MOZ_LOGdan MOZ_LOG_FILElingkungan, dan mencatat permintaan http pada tingkat debug (4 = PR_LOG_DEBUG) - map.put("MOZ_LOG", "timestamp,sync,nsHttp:4"). Simpan log di file sementara. Setelah itu, dapatkan konten file log yang disimpan dan parsing untuk kode respons (menggunakan beberapa ekspresi reguler sederhana). Pertama, deteksi awal permintaan, identifikasi id-nya (nsHttpChannel::BeginConnect [this=000000CED8094000]), lalu di langkah kedua, temukan kode respons untuk id permintaan tersebut (nsHttpChannel::ProcessResponse [this=000000CED8094000 httpStatus=200]).

Anda dapat menggunakan proxy BrowserMob untuk menangkap permintaan dan tanggapan dengan file HttpRequestInterceptor. Berikut ini contohnya di 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();

Bagi orang-orang yang menggunakan Python, Anda dapat mempertimbangkan Selenium Wire , perpustakaan yang saya kembangkan untuk memeriksa permintaan yang dibuat oleh browser selama pengujian.

Anda mendapatkan akses ke permintaan melalui driver.requestsatribut:

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']
        )

Pustaka memberi Anda kemampuan untuk mengakses header, kode status, konten isi, serta kemampuan untuk mengubah header dan menulis ulang URL.

Saya juga mengalami masalah yang sama dan macet selama beberapa hari, tetapi setelah beberapa penelitian, saya menemukan bahwa kami sebenarnya dapat menggunakan "--remote-debugging-port" chrome untuk mencegat permintaan dalam hubungannya dengan driver web selenium. Gunakan Pseudocode berikut sebagai referensi: -

buat instance driver chrome dengan debugging jarak jauh

int freePort = findFreePort();

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

ChromeDriver driver = new ChromeDriver(chromeOptions);`

lakukan panggilan ke http://127.0.0.1:freePort

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

Ekstrak URL webSocket chrome untuk mendengarkan, Anda dapat melihat respons dan mencari cara untuk mengekstrak

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

Hubungkan ke soket ini, Anda dapat menggunakan asyncHttp

socket = maketSocketConnection( webSocketUrl );

Aktifkan penangkapan jaringan

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

Sekarang chrome akan mengirim semua acara terkait jaringan dan menangkapnya sebagai berikut

socket.onMessageReceived( String message ){

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

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

Anda dapat melakukan semua yang disebutkan di situs alat dev. lihat https://chromedevtools.github.io/devtools-protocol/ Catatan: - gunakan chromedriver 2.39 atau lebih tinggi.

Saya harap ini membantu seseorang.

Dapatkan Kode Respon dalam Bahasa Apa Pun (Menggunakan JavaScript):

Jika pengujian Selenium Anda berjalan di browser modern, cara mudah untuk mendapatkan kode respons adalah dengan mengirim XMLHttpRequest* sinkronis dan memeriksa statusrespons:

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

assert(200, xhr.status);

Anda dapat menggunakan teknik ini dengan bahasa pemrograman apa pun dengan meminta Selenium menjalankan skrip. Misalnya, di Java Anda dapat menggunakan JavascriptExecutor.executeScript()untuk mengirim 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"));

* Anda dapat mengirim asynchronous XMLHttpRequestsebagai gantinya, tetapi Anda harus menunggu hingga selesai sebelum melanjutkan pengujian Anda.

Dapatkan Kode Respon di Java:

Anda bisa mendapatkan kode respons di Java dengan menggunakan URL.openConnection()dan 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());

Metode ini mungkin bisa digeneralisasikan ke bahasa lain juga, tetapi perlu dimodifikasi agar sesuai dengan API bahasa (atau pustaka).

Tidak yakin ini yang Anda cari, tetapi saya memiliki tujuan yang sedikit berbeda adalah untuk memeriksa apakah gambar jarak jauh ada dan saya tidak akan memiliki kesalahan 403, jadi Anda dapat menggunakan sesuatu seperti di bawah ini:

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;
    }
}

Tidak mungkin mendapatkan kode Respon HTTP dengan menggunakan Selenium WebDriver secara langsung. Kode tersebut dapat diperoleh dengan menggunakan kode Java dan dapat digunakan di Selenium WebDriver.

Untuk mendapatkan kode Respon HTTP oleh 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();
}

Sekarang Anda dapat menulis kode Selenium WebDriver Anda seperti di bawah ini:

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"));
                }
            }
        }   
    }   
}

Anda dapat mencoba Mobilenium ( https://github.com/rafpyprog/Mobilenium ), paket python yang mengikat BrowserMob Proxy dan Selenium.

Contoh penggunaan:

>>> 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'
