Java Selenium得到JSON響應體

Question

我用Selenium webdriver使用Java，我想知道是否有可能獲得JSON體響應？我問，因爲它有可能獲得使用此代碼JSON請求體：

driver.manage().logs().get(LogType.PERFORMANCE); 

，但我不能從響應得到的身體，但反應也存在於這個日誌。有什麼辦法得到響應體？

由於未決問題，Geckodriver的，https://github.com/mozilla/geckodriver/issues/764

所以你需要使用一種變通方法，做GeckoDriver確實在後臺爲你

import net.lightbody.bmp.BrowserMobProxyServer; 
import net.lightbody.bmp.client.ClientUtil; 
import net.lightbody.bmp.core.har.Har; 
import net.lightbody.bmp.proxy.CaptureType; 
import org.openqa.selenium.Proxy; 
import org.openqa.selenium.firefox.FirefoxDriver; 
import org.openqa.selenium.firefox.FirefoxProfile; 

import java.io.File; 
import java.io.IOException; 

/** 
* Created by tarun.lalwani on 08/29/17. 
*/ 
public class TestApp { 


    public static void main(String [] args) { 

     BrowserMobProxyServer proxyServer = new BrowserMobProxyServer(); 
     proxyServer.start(); 
     proxyServer.setHarCaptureTypes(CaptureType.getAllContentCaptureTypes()); 
     proxyServer.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT); 
     Proxy proxy = ClientUtil.createSeleniumProxy(proxyServer); 
     FirefoxProfile profile = new FirefoxProfile(); 

     String host = proxy.getHttpProxy().split(":")[0]; 
     int port = Integer.parseInt(proxy.getHttpProxy().split(":")[1]); 


     profile.setPreference("network.proxy.type", 1); 
     profile.setPreference("network.proxy.http", host); 
     profile.setPreference("network.proxy.http_port", port); 
     profile.setPreference("network.proxy.ssl", host); 
     profile.setPreference("network.proxy.ssl_port", port); 
     FirefoxDriver driver = new FirefoxDriver(profile); 

     proxyServer.newHar("mysite"); 

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

     Har har = proxyServer.getHar(); 
     try { 
      har.writeTo(new File("har.json")); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
}

因爲y你想用Java來做到這一點。您需要使用BrowserMobProxy庫爲Java及以下樣的代碼爲你

import net.lightbody.bmp.BrowserMobProxy; 
import net.lightbody.bmp.BrowserMobProxyServer; 
import net.lightbody.bmp.client.ClientUtil; 
import net.lightbody.bmp.core.har.Har; 
import net.lightbody.bmp.proxy.CaptureType; 


..... 

BrowserMobProxy proxy = new BrowserMobProxyServer(); 
proxy.start(0); 

Proxy selProxy = ClientUtil.createSeleniumProxy(proxy); 

DesiredCapabilities cap = new DesiredCapabilities(); 
cap.setCapability(CapabilityType.PROXY, selProxy); 


WebDriver driver = new FirefoxDriver(capabilities); 

proxy.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT); 

proxy.newHar("mysite"); 

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


Har har = proxy.getHar(); 

原來的答案

您需要安裝Firefox的一個BrowserMobProxy應該工作。下面的代碼會爲你

import time 
from selenium import webdriver 

from browsermobproxy import Server 
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities 
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile 

server = Server("/path/to/bin/browsermob-proxy") 
server.start() 
# If sleep is not added sometime `create_proxy` throws an error 
time.sleep(2) 
proxy = server.create_proxy() 

sel_proxy = proxy.selenium_proxy() 

profile = FirefoxProfile() 
profile.set_proxy(sel_proxy) 
driver = webdriver.Firefox(firefox_profile=profile) 
proxy.new_har("mysite", options={'captureHeaders': True, 'captureContent': True}) 
driver.get("http://tarunlalwani.com") 
print(proxy.har) 

工作這會給輸出像下面

我建議你看一下對於跟蹤網絡活動的專用工具，如Browsermob Proxy，這可能與硒輕鬆集成。內部硒日誌不適合這種用途。
