How to set proxy for Chrome browser in selenium using Java code

Question

I am trying to run my selenium java code to test a webpage. But webpage is not loading because of network restrictions. When I set the proxy manually and hit the url in browser

Answer 1

DesiredCapabilities dc;
dc = DesiredCapabilities.chrome();              
System.setProperty("http.proxyHost", "127.0.0.1");
System.setProperty("http.proxyPort", "9090");
System.setProperty("https.proxyHost", "127.0.0.1");
System.setProperty("https.proxyPort", "9090");                      
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized");
options.addArguments("--disable-extensions");
dc.setCapability(ChromeOptions.CAPABILITY, options);
driver = new ChromeDriver(dc);

Answer 2

Issue is resolved with below code -

Proxy proxy = new Proxy(); 
proxy.setHttpProxy("yoururl:portno"); 
proxy.setSslProxy("yoururl:portno"); 

DesiredCapabilities capabilities = DesiredCapabilities.chrome(); 
capabilities.setCapability("proxy", proxy); 

ChromeOptions options = new ChromeOptions(); 
options.addArguments("start-maximized"); 

capabilities.setCapability(ChromeOptions.CAPABILITY, options); 

driver = new ChromeDriver(capabilities);

Answer 3

Another way of doing it:

        boolean useProxy = true;
        ChromeOptions options = new ChromeOptions().addArguments(
                '--headless',
                '--no-sandbox',
                '--disable-extensions',
                '--proxy-bypass-list=localhost');
        if (useProxy) {
            options.addArguments("--proxy-server=http://ProxyHost:8080");
        }

        WebDriver driver = new ChromeDriver(options);

Answer 4

Passing a Capabilities object to the ChromeDriver() constructor is deprecated. One way to use a proxy is this:

String proxy = "127.0.0.1:5000";
ChromeOptions options = new ChromeOptions().addArguments("--proxy-server=http://" + proxy);
WebDriver webDriver = new ChromeDriver(options);

Answer 5

Passing a Capabilities object to the ChromeDriver() constructor is deprecated. You can find new official doc here.

ChromeOptions chromeOptions = new ChromeOptions();

Proxy proxy = new Proxy();
proxy.setAutodetect(false);
proxy.setHttpProxy("http_proxy-url:port"); 
proxy.setSslProxy("https_proxy-url:port");
proxy.setNoProxy("no_proxy-var");

chromeOptions.setCapability("proxy", proxy); 
driver = new ChromeDriver(chromeOptions);
