如何使用 Selenium WebDriver 获取 HTTP 响应代码

小开

最佳答案

一句话，没有。使用 Selenium WebDriver API 是不可能的。这已经在该项目的问题追踪器中令人作呕地讨论过了，这个特性将不会被添加到 API 中。

不知道这是不是你要找的，但我有一个不同的目标是检查是否存在远程图像，我不会有403错误，所以你可以使用如下:

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;
}
}

您可以使用 BrowserMob 代理以 HttpRequestInterceptor捕获请求和响应:

// 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();

直接使用 SeleniumWebDriver 不可能获得 HTTP 响应代码。这些代码可以通过使用 Java 代码获得，并且可以在 SeleniumWebDriver 中使用。

通过 java 获取 HTTP 响应代码:

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();
}

现在您可以编写如下 Selenium WebDriver 代码:

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"));
}
}
}
}
}

可以使用 Selenium 和 Chrome 或 Firefox 获取 http 请求的响应代码。你所要做的就是在日志模式下启动 Chrome 或 Firefox。我将在下面给你们展示一些例子。

Java + Selenium + Chrome 这里有一个 java + Selenium + Chrome 的例子，但是我猜想它可以用任何语言来实现(python，c # ，...)。

所有你需要做的就是告诉 chrome 驱动程序做“ Network.able”。这可以通过启用性能日志来完成。

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

在请求完成之后，您所要做的就是获取并迭代 Performance 日志，并为请求的 URL 找到“ Network.response seRecected”:

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

密码如下:

import java.util.Iterator;
import java.util.logging.Level;


import org.json.JSONException;
import org.json.JSONObject;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.logging.LogEntries;
import org.openqa.selenium.logging.LogEntry;
import org.openqa.selenium.logging.LogType;
import org.openqa.selenium.logging.LoggingPreferences;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;


public class TestResponseCode
{
public static void main(String[] args)
{
// simple page (without many resources so that the output is
// easy to understand
String url = "http://www.york.ac.uk/teaching/cws/wws/webpage1.html";


DownloadPage(url);
}


private static void DownloadPage(String url)
{
ChromeDriver driver = null;


try
{
ChromeOptions options = new ChromeOptions();
// add whatever extensions you need
// for example I needed one of adding proxy, and one for blocking
// images
// options.addExtensions(new File(file, "proxy.zip"));
// options.addExtensions(new File("extensions",
// "Block-image_v1.1.crx"));


DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability(ChromeOptions.CAPABILITY, options);


// set performance logger
// this sends Network.enable to chromedriver
LoggingPreferences logPrefs = new LoggingPreferences();
logPrefs.enable(LogType.PERFORMANCE, Level.ALL);
cap.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);


driver = new ChromeDriver(cap);


// navigate to the page
System.out.println("Navigate to " + url);
driver.navigate().to(url);


// and capture the last recorded url (it may be a redirect, or the
// original url)
String currentURL = driver.getCurrentUrl();


// then ask for all the performance logs from this request
// one of them will contain the Network.responseReceived method
// and we shall find the "last recorded url" response
LogEntries logs = driver.manage().logs().get("performance");


int status = -1;


System.out.println("\nList of log entries:\n");


for (Iterator<LogEntry> it = logs.iterator(); it.hasNext();)
{
LogEntry entry = it.next();


try
{
JSONObject json = new JSONObject(entry.getMessage());


System.out.println(json.toString());


JSONObject message = json.getJSONObject("message");
String method = message.getString("method");


if (method != null
&& "Network.responseReceived".equals(method))
{
JSONObject params = message.getJSONObject("params");


JSONObject response = params.getJSONObject("response");
String messageUrl = response.getString("url");


if (currentURL.equals(messageUrl))
{
status = response.getInt("status");


System.out.println(
"---------- bingo !!!!!!!!!!!!!! returned response for "
+ messageUrl + ": " + status);


System.out.println(
"---------- bingo !!!!!!!!!!!!!! headers: "
+ response.get("headers"));
}
}
} catch (JSONException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}


System.out.println("\nstatus code: " + status);
} finally
{
if (driver != null)
{
driver.quit();
}
}
}
}

输出如下:

status code: 200

Java + Selenium + Firefox 我也终于找到了 Firefox 的诀窍。您需要使用 MOZ_LOG和 MOZ_LOG_FILE环境变量启动 firefox，并在调试级别 (4 = PR_LOG_DEBUG) - map.put("MOZ_LOG", "timestamp,sync,nsHttp:4")记录 http 请求。将日志保存在临时文件中。然后，获取保存的日志文件的内容并解析它以获得响应代码(使用一些简单的正则表达式)。首先检测请求的开始，识别它的 id (nsHttpChannel::BeginConnect [this=000000CED8094000])，然后在第二步，找到该请求 id (nsHttpChannel::ProcessResponse [this=000000CED8094000 httpStatus=200])的响应代码。

您可以尝试 Mobilenium (https://github.com/rafpyprog/Mobilenium) ，这是一个绑定 BrowserMob Proxy 和 Selenium 的 Python 包。

一个用法例子:

>>> 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

获取任何语言的响应代码(使用 JavaScript) :

如果您的 Selenium 测试在现代浏览器中运行，获得响应代码的一个简单方法是发送一个同步的 XMLHttpRequest * 并检查响应的 status:

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


assert(200, xhr.status);

通过请求 Selenium 执行脚本，您可以将此技术用于任何编程语言。例如，在 Java 中，您可以使用 JavascriptExecutor.executeScript()发送 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"));

* 可以发送一个异步 XMLHttpRequest，但是在继续测试之前需要等待它完成。

用 Java 获取响应代码:

您可以使用 URL.openConnection()和 HttpURLConnection.getResponseCode()获得 Java 中的响应代码:

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());

这种方法也可以推广到其他语言，但需要进行修改以适应该语言的(或库的) API。

我也遇到过同样的问题，有几天卡住了，但经过一些研究，我发现我们实际上可以使用 chrome 的“远程调试端口”与硒网络驱动程序一起拦截请求。使用以下伪代码作为参考:-

通过远程调试创建 Chrome 驱动程序实例

int freePort = findFreePort();


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


ChromeDriver driver = new ChromeDriver(chromeOptions);`

打电话给 http://127.0.0.1:freePort

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

提取 chrome 的 webSocketUrl 来听，你可以看到响应，并找出如何提取

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

连接到此套接字时，可以使用 syncHttp

socket = maketSocketConnection( webSocketUrl );

启用网络捕获

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

现在，chrome 将发送所有与网络相关的事件并捕获它们，如下所示

socket.onMessageReceived( String message ){


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


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

您可以完成开发工具站点中提到的所有工作。见 https://chromedevtools.github.io/devtools-protocol/ 注:-使用2.39或以上的色差驱动器。

我希望能帮到别人。

对于那些使用 Python 的人，您可以考虑使用硒丝，这是一个用于在测试期间检查浏览器发出的请求的库。

您可以通过 driver.requests属性访问请求:

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']
)

该库使您能够访问标题、状态代码、主体内容，以及修改标题和重写 URL 的能力。

请尝试以下代码:

HttpURLConnection c= (HttpURLConnection)new
URL("https://www.google.com")
.openConnection();
// set the HEAD request with setRequestMethod
c.setRequestMethod("HEAD");
// connection started and get response code
c.connect();
int r = c.getResponseCode();
System.out.println("Http response code: " + r);
