javax.net.ssl.SSLHandshakeException in Selenium Java Class

Question

这是我在Java Selenium中查找页面中断开的链接的程序

我在链接 https://www.zlti.com 的 huc.connect(( 行中面临 SSLHandshake 异常问题。但是我可以在浏览器中打开链接

javax.net.ssl.SSLHandshakeException： sun.security.validator.ValidatorException： PKIX 路径构建失败： sun.security.provider.certpath.SunCertPathBuilderException： 无法找到所请求目标的有效证书路径

String homePage = "https://www.zlti.com";
String url = "";
HttpsURLConnection huc = null;
int respCode = 200;
System.setProperty("webdriver.chrome.driver", "/usr/bin/chromedriver");
DesiredCapabilities handlSSLErr = new DesiredCapabilities();
handlSSLErr.setCapability (CapabilityType.ACCEPT_SSL_CERTS, true);
driver = new ChromeDriver(handlSSLErr);

driver.manage().window().maximize();
driver.get(homePage);
List<WebElement> links = driver.findElements(By.tagName("a"));
Iterator<WebElement> it = links.iterator();

while(it.hasNext()){
url = it.next().getAttribute("href");
System.out.println(url);
if(url == null || url.isEmpty()){
System.out.println("URL is either not configured for anchor tag or it is empty");
continue;
}
if(!url.startsWith(homePage)){
System.out.println("URL belongs to another domain, skipping it.");
continue;
}
try {
huc = (HttpsURLConnection)(new URL(url).openConnection());
huc.setRequestMethod("HEAD");
huc.connect();
respCode = huc.getResponseCode();
if(respCode >= 400){
System.out.println(url+" is a broken link");
}
else{
System.out.println(url+" is a valid link");
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
driver.quit();
}
}

Answer 1

添加了这段代码以使其工作

try {
SSLContext ssl_ctx = SSLContext.getInstance("TLS");
TrustManager[ ] trust_mgr = new TrustManager[ ] {
new X509TrustManager() {
public X509Certificate[ ] getAcceptedIssuers() { return null; }
public void checkClientTrusted(X509Certificate[ ] certs, String t) { }
public void checkServerTrusted(X509Certificate[ ] certs, String t) { }
}
};
ssl_ctx.init(null,                // key manager
trust_mgr,           // trust manager
new SecureRandom()); // random number generator
HttpsURLConnection.setDefaultSSLSocketFactory(ssl_ctx.getSocketFactory());
} catch(NoSuchAlgorithmException e) {
e.printStackTrace();
} catch(KeyManagementException e) {
e.printStackTrace();
}
