代码如下
@Test
public void testHtmlUnit() throws Exception {
WebClient client = new WebClient(BrowserVersion.CHROME);
// client.getOptions().setUseInsecureSSL(true);
HtmlPage page = client.getPage("https://10.167.33.50/user");
HtmlElement username = page.getElementByName("usrname");
username.type("ns25000");
HtmlElement pwd = page.getElementByName("pass");
pwd.type("ns25000");
page.executeJavaScript("submitbutton(‘login‘,‘loginForm‘);");
System.out.print(page.getWebResponse().getContentAsString());
}
运行错误如下

发现应当是https的证书过期或不受信任。google之，发现htmlunit也是采用httpclient，因此采用了httpclient的解决办法
SSLContext sslContext = SSLContext.getInstance("SSL");
// set up a TrustManager that trusts everything
sslContext.init(null, new TrustManager[] { new X509TrustManager() {
public X509Certificate[] getAcceptedIssuers() {
System.out.println("getAcceptedIssuers =============");
return null;
}
public void checkClientTrusted(X509Certificate[] certs,
String authType) {
System.out.println("checkClientTrusted =============");
}
public void checkServerTrusted(X509Certificate[] certs,
String authType) {
System.out.println("checkServerTrusted =============");
}
} }, new SecureRandom());
SSLSocketFactory sf = new SSLSocketFactory(sslContext);
Scheme httpsScheme = new Scheme("https", 443, sf);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(httpsScheme);
// apache HttpClient version >4.2 should use BasicClientConnectionManager
ClientConnectionManager cm = new SingleClientConnManager(schemeRegistry);
HttpClient httpClient = new DefaultHttpClient(cm);
以上答案无果……
继续谷歌之（大谷歌不能用，还有谷搜客）
找到如下
解决方案：
For future reference if someone wants to do the same thing its fairly
straight forward.
1)Create a package called
org.apache.commons.httpclient.contrib.ssl
add the two files.
EasySSLProtocolSocketFactory.java
EasyX509TrustManager.java
Compile.
2)Add the following lines of code to your htmlclient before making any
htmlunit calls
Protocol easyhttps = new Protocol("https", new
EasySSLProtocolSocketFactory(), 443);
Protocol.registerProtocol("https", easyhttps);
对应两个java文件如下
按照修改后依旧不起作用
最后看到作者描述
FYI, starting with version 1.14 you can use WebClient.setUseInsecureSSL(true) instead, and it will take care of all the HttpClient configuration behind the scenes.
好激动……
使用是发现webclient没有此方法，原来已被提取自webclientoptions类中。
/**
* If set to <code>true</code>, the client will accept connections to any host, regardless of
* whether they have valid certificates or not. This is especially useful when you are trying to
* connect to a server with expired or corrupt certificates.
* @param useInsecureSSL whether or not to use insecure SSL
*/
public void setUseInsecureSSL(final boolean useInsecureSSL) {
useInsecureSSL_ = useInsecureSSL;
}
因此将代码修改至
@Test
public void testHtmlUnit() throws Exception {
WebClient client = new WebClient(BrowserVersion.CHROME);
client.getOptions().setUseInsecureSSL(true);
HtmlPage page = client.getPage("https://10.167.33.50/user");
HtmlElement username = page.getElementByName("usrname");
username.type("ns25000");
HtmlElement pwd = page.getElementByName("pass");
pwd.type("ns25000");
page.executeJavaScript("submitbutton(‘login‘,‘loginForm‘);");
System.out.print(page.getWebResponse().getContentAsString());
}
OK~
