【已解决】Java中模拟登陆百度期间通过HttpClient无法获得所希望的返回的html和cookie

【背景】

折腾：

期间，用如下代码：

    /** Get response from url  */
    public HttpResponse getUrlResponse(
    		String url,
    		List<NameValuePair> headerDict,
    		List<NameValuePair> postDict,
    		int timeout
    		)
    {
    	// init
    	HttpResponse response = null;
    	HttpUriRequest request = null;
    	DefaultHttpClient httpClient = new DefaultHttpClient();
    	
    	//HttpParams headerParams = new HttpParams();
    	//HttpParams headerParams = new DefaultedHttpParams(headerParams, headerParams);
    	//HttpParams headerParams = new BasicHttpParams();
    	BasicHttpParams headerParams = new BasicHttpParams();
    	//HttpConnectionParams.
		//default enable auto redirect
    	headerParams.setParameter(CoreProtocolPNames.USER_AGENT, gUserAgent);
    	headerParams.setParameter(ClientPNames.HANDLE_REDIRECTS, Boolean.TRUE);
    	
    	if(postDict != null)
    	{
    		HttpPost postReq = new HttpPost(url);
    		
    		try{
    			HttpEntity postBodyEnt = new UrlEncodedFormEntity(postDict);
    			postReq.setEntity(postBodyEnt);
    		}
    		catch(Exception e){
    			e.printStackTrace();
    		}

    		request = postReq;
    	}
    	else
    	{
        	HttpGet getReq = new HttpGet(url);
        	
        	request = getReq;
    	}

    	if(headerParams != null)
    	{
    		//HttpProtocolParams.setUserAgent(headerParams, gUserAgent);
    		//headerParams.setHeader(HttpMethodParams.USER_AGENT, gUserAgent);
    		request.setParams(headerParams);
    	}
    	
    	//request.setHeader("User-Agent", gUserAgent);
    	

		try{			
			HttpContext localContext = new BasicHttpContext();
			localContext.setAttribute(ClientContext.COOKIE_STORE, gCurCookieStore);

}

始终还是无法获得对应的返回的html和cookie，从而无法正常模拟登陆。

【折腾过程】

1.很是怀疑，是不是其中的自动跳转，没有工作。

即：

headerParams.setParameter(ClientPNames.HANDLE_REDIRECTS, Boolean.TRUE);

没有起到对应的自动跳转的效果，即：

正常，自动跳转后的结果，应该是：

{Connection: keep-alive
Pragma: public

Cache-Control: public
Content-Type: text/html

Server: 
Vary: Accept-Encoding
Content-Encoding: 

}

而现在，返回的结果，是没有跳转时，所返回的结果：

{Transfer-Encoding: chunked
Connection: keep-alive
Pragma: public
Vary: Accept-Encoding
Content-Encoding: 
Cache-Control: public
Content-Type: text/html

P3P: CP=" OTI DSP COR IVA OUR IND COM "
Server: 

}

2.参考：

How auto redirect in HttpClient (java, apache)

说是：

HttpClient 3.x不支持自动跳转

HttpClient 4.x 就支持了。

3.我这里的HttpClient，是之前：

【已解决】Eclipse的java代码出错：The import org.apache cannot be resolved

中加的，去看了下，的确已经是4.2.5，是支持的了。

4.看到：

Interface ClientPNames

已不推荐再使用ClientPNames了，改推荐：

Class RequestConfig

但是好像是4.3的，我此处，用的是4.2的库，应该是不支持的。

5.我此处调试的时候，其实可以看到对应的设置的：

{http.useragent=Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.3; .NET4.0C; .NET4.0E, http.protocol.handle-redirects=true}

但是，现实的返回结果，貌似是没有自动跳转的。

6.再继续调试，经过：

request.setParams(headerParams);

是可以将对应的上面的header信息，设置给request的：

7.后来继续调试，发现好像不是自动跳转的问题。

貌似是cookie的问题。

正常的话的，C#中，访问：

https://passport.baidu.com/v2/api/?login

之前的cookie是：

而此处，调试看到的cookie却是：

[
    [version: 0][name: BAIDUID][value: 8EFD622E00F965E706C2F4CC3A392AF9:FG=1][domain: .baidu.com][path: /][expiry: Thu Sep 17 16:38:11 CST 2043],
    [version: 0][name: BDSVRTM][value: 1][domain: www.baidu.com][path: /][expiry: null],
    [version: 0][name: HOSUPPORT][value: 1][domain: passport.baidu.com][path: /][expiry: Sat Dec 04 16:38:12 CST 2021],
    [version: 0][name: H_PS_PSSID][value: 3361_3381_1447_2976][domain: .baidu.com][path: /][expiry: Sat Oct 17 00:00:00 CST 2043]
]

很明显，其中的：

BDSVRTM：

domain不对
expiry不对

H_PS_PSSID：

已经经过上述手动加代码，修复了不对的expiry

所以，去手动添加代码修正这些cookie：

        	BasicClientCookie hPsPssidCookie = null;
        	BasicClientCookie dbsvrtmCookie = null;
        	//int hPsPssidCookieIdx = 0;
        	
        	curCookieList = crl.getCurCookieList();
        	for(Cookie ck : curCookieList)
        	{
        		if(ck.getName().equalsIgnoreCase("H_PS_PSSID"))
        		{
        			//hPsPssidCookieIdx = curCookieList.indexOf(ck);
        			hPsPssidCookie = (BasicClientCookie) ck;
        			hPsPssidCookie.setExpiryDate(newExpiryDate);
        			ck = hPsPssidCookie;
        			//break;
        		}
        		
        		if(ck.getName().equalsIgnoreCase("BDSVRTM"))
        		{
        			dbsvrtmCookie = (BasicClientCookie) ck;
        			dbsvrtmCookie.setDomain(".baidu.com");
        			dbsvrtmCookie.setExpiryDate(newExpiryDate);
        			ck = dbsvrtmCookie;
        			//break;
        		}
        	}
        	
        	crl.setCurCookieList(curCookieList);

修改后为：

[
    [version: 0][name: BAIDUID][value: B3CCB8F5D6DA04D26A3CF718FDE8A753:FG=1][domain: .baidu.com][path: /][expiry: Thu Sep 17 16:57:38 CST 2043],
    [version: 0][name: BDSVRTM][value: 1][domain: .baidu.com][path: /][expiry: Sat Oct 17 00:00:00 CST 2043],
    [version: 0][name: HOSUPPORT][value: 1][domain: passport.baidu.com][path: /][expiry: Sat Dec 04 16:57:39 CST 2021],
    [version: 0][name: H_PS_PSSID][value: 3359_3381_1422_2975_2981_3092][domain: .baidu.com][path: /][expiry: Sat Oct 17 00:00:00 CST 2043]
]

看看结果如何。

结果问题依旧。

8.但是，注意到此处的输出的html是：

</html>

看起来，貌似右向正常的返回的html。

所以，真的再次去C#项目中，设置autoredirect为false，看看其返回的结果如何。

结果是：

C#中，如果也是设置autoredirect为false的话，那么返回的内容，也是：

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>


<script type="text/javascript">

var url = encodeURI('http://www.baidu.com/cache/user/html/jump.html?callback=parent.bdPass.api.login._postCallback&index=0&codestring=captchaservice64346332423033614479666e5a4c6f336a67534864484939683445457846644676452f4734437858723973515236505979696c4d7a726a385447706a6b7349497055316c426e4a577335553945432b3452433361374b325a475a6863396d496e7866477a5771524a4a734457795147442f3445704d533071747a6633386e70543651785663725837515344316b4a74423473614447676653547a7461596b6c726c75334a624d38556a3679706f4d48567875736565624b32584f796d476e646f363179486b426831767745443946397635725250516e305552417432663566486a6176787675757070636a4d53452b3575796a434434456d4b6b4a56305837594b6c41725965636974794a59494c3848423858413771325542657a6a393464326a5973&username=xxx&phonenumber=&mail=&tpl=mn&u=https%3A%2F%2Fpassport.baidu.com%2F&needToModifyPassword=&gotourl=&auth=&error=257');
//parent.callback(url)
window.location.replace(url);

</script>
</body>
</html>

但是，注意到，此处C#中，获得的html中，是有：

username=xxx

的，而java中返回的html中是没有的。

9.然后想到，会不会是由于connection不是keep-alive而导致的？

所以，去确认java中的connection，的确是keep-alive

参考：

Tomcat, HTTP Keep-Alive and Java’s HttpsUrlConnection

【整理】关于Java中的httpClient中可以传入的参数

而加入了：

headerParams.setParameter(CoreConnectionPNames.SO_KEEPALIVE, Boolean.TRUE);

试试效果。

结果问题依旧，返回的html中，还是没有username：

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>


<script type="text/javascript">

var url = encodeURI('http://www.baidu.com/cache/user/html/jump.html?callback=parent.bdPass.api.login._postCallback&index=0&codestring=captchaservice6330386433734b6a45483661695042706663673772305a65396d2b6261636753473545314b41795932745136774576595746576a465557376a2f513332523230596f675a68434b63553738734337645567664643304878665839306e56696d74335535415637716c437379376b2f496f3451626e492f4d50684e4f616d59316b346131476e6163366f6945764d7a476a7976455543614954533066307a59333555646f6a46594f616f3078324b42585870515866496f5473676b3632566e4d36732b47682b494342314837702f572f38635757636f6a4a6e7845564a6f6c68416377596b362b725a2b314742475562435a4844315a376f4b75555942416f7239716f4b6a5762514d516b7a453749484d4766426e3044424f7462615169494d35&username=&phonenumber=&mail=&tpl=mn&u=https%3A%2F%2Fpassport.baidu.com%2F&needToModifyPassword=&gotourl=&auth=&error=257');
//parent.callback(url)
window.location.replace(url);

</script>
</body>
</html>

另外，参考：

What is HTTP Persistent Connections?

其实已经说是默认是true了。

10.另外，注意到，之前C#正常的时候，cookie中的：

BDSVRTM的值是2

而此处的java的

BDSVRTM的值，始终是1

所以，要去研究一下，原先的C#中，什么时候得到的BDSVRTM是2的。

调试C#项目，确定了：

autoredirect为false的时候，用某个账户（3），也是可以正常模拟登陆的；

且BDSVRTM值也是1，且返回的html也是上述的html，但是其中是包含username的。

所以，再去java中看看。

结果java中，还是返回html中不带username的。

还是无法获得对应的cookie。

11.然后的然后，去检查自己代码，看看post data中是否少传了什么参数，结果发现一个惊天大问题：

之前只注意去java中从控制台中获得用户名和密码，结果竟然忘了将用户名和密码传入到post data中。。。。

你妹的，这个也太疏忽了。。。

所以，去加上，变成：

        	String staticPageUrl = "http://www.baidu.com/cache/user/html/jump.html";

        	//List<NameValuePair> headerDict = new List<NameValuePair>();
        	List<NameValuePair> postDict = new ArrayList<NameValuePair>();
        	//ArrayList<NameValuePair> headerDict = new ArrayList<NameValuePair>();
            //postDict.Add("ppui_logintime", "");
            postDict.add(new BasicNameValuePair("charset", "utf-8"));
            //postDict.add(new BasicNameValuePair("codestring", ""));
            //postDict.Add("", "");
            postDict.add(new BasicNameValuePair("token", strTokenValue));
            postDict.add(new BasicNameValuePair("isPhone", "false"));
            postDict.add(new BasicNameValuePair("index", "0"));
            //postDict.add(new BasicNameValuePair("u", ""));
            //postDict.add(new BasicNameValuePair("safeflg", "0"));
            postDict.add(new BasicNameValuePair("staticpage", staticPageUrl));
            postDict.add(new BasicNameValuePair("loginType", "1"));
            postDict.add(new BasicNameValuePair("tpl", "mn"));
            postDict.add(new BasicNameValuePair("callback", "parent.bdPass.api.login._postCallback"));
        	
            String strBaiduUsername = "";
        	String strBaiduPassword = "";
            Scanner inputReader = new Scanner(System.in);
            System.out.println("Please Enter Your:" );
            System.out.println("Baidu Username:" );
            strBaiduUsername = inputReader.nextLine();
            System.out.println("You Entered Username=" + strBaiduUsername);
            System.out.println("Baidu Password:" );
            strBaiduPassword = inputReader.nextLine();
            System.out.println("You Entered Password=" + strBaiduPassword);
            
            postDict.add(new BasicNameValuePair("username", strBaiduUsername));
            postDict.add(new BasicNameValuePair("password", strBaiduPassword));
            
            postDict.add(new BasicNameValuePair("verifycode", ""));
            
            postDict.add(new BasicNameValuePair("mem_pass", "on"));

            String baiduMainLoginUrl = "https://passport.baidu.com/v2/api/?login";
            String loginBaiduRespHtml = crl.getUrlRespHtml(baiduMainLoginUrl, null, postDict);

然后再去试试：

就可以了：

也可以返回cookie了：

[

]

返回的html中，也带username了：

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>


<script type="text/javascript">

//parent.callback(url)
window.location.replace(url);

</script>
</body>
</html>

12.然后，此处，其实又出现一点点小意外：

java中，返回的cookie中，没有：SAVEUSERID

而C#中，返回的cookie中是有：SAVEUSERID的。

然后去看看获得的response，结果是，其中的cookie中，是有SAVEUSERID的：

Set-Cookie: BDUSS=stVkRscHpnak5yVXJLcFpUVENqczF1Q3NhbmltV2Rwc2V-bmp6Q3JzT2ZzVjlTQVFBQUFBJCQAAAAAAAAAAAEAAAAZP0gCYWdhaW5pbnB1dDMAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAJ8kOFKfJDhSaG; expires=Sat, 04-Dec-2021 09:45:04 GMT; path=/; domain=baidu.com; httponly,
Set-Cookie: PTOKEN=deleted; expires=Mon, 17-Sep-2012 09:45:03 GMT; path=/; domain=baidu.com; httponly,
Set-Cookie: PTOKEN=d75d78bd32c23c5cdb9c27b2f484ea9c; expires=Sat, 04-Dec-2021 09:45:04 GMT; path=/; domain=passport.baidu.com; httponly,
Set-Cookie: STOKEN=75ba9addf1f921c25a64dd7f7d278d40; expires=Sat, 04-Dec-2021 09:45:04 GMT; path=/; domain=passport.baidu.com; httponly,
Set-Cookie: SAVEUSERID=deleted; expires=Mon, 17-Sep-2012 09:45:03 GMT; path=/; domain=passport.baidu.com; httponly,
Set-Cookie: USERNAMETYPE=1; expires=Sat, 04-Dec-2021 09:45:04 GMT; path=/; domain=passport.baidu.com; httponly

但是很明显，SAVEUSERID是deleted，

所以被java中的代码解析后，就被丢掉了。

所以，此处，java中，获得的CookieStore，是没有SAVEUSERID的。其实就是正常的现象了。

所以，java中，判断模拟登陆百度成功后的cookie的判断，就需要修改一下，去掉针对于SAVEUSERID的判断，变成：

            //Map cookieNameDict = new Map();
            Map cookieNameDict = new Hashtable();
            //Map<Object, Object> cookieNameDict = new Hashtable<Object, Object>;
            cookieNameDict.put("BDUSS", false);
            cookieNameDict.put("PTOKEN", false);
            cookieNameDict.put("STOKEN", false);
            //cookieNameDict.put("SAVEUSERID", false);
            
            curCookieList = crl.getCurCookieList();
            for(Object objCookieName : cookieNameDict.keySet().toArray())
            {
            	String strCookieName = objCookieName.toString();
                for(Cookie ck: curCookieList)
                {
                	if(strCookieName.equalsIgnoreCase(ck.getName()))
                	{
                		cookieNameDict.put(strCookieName, true);
                	}
                }
            }
            
            boolean bAllCookiesFound = true;
            for (Object  objFoundCurCookie : cookieNameDict.values())
            {
            	bAllCookiesFound = bAllCookiesFound && Boolean.parseBoolean(objFoundCurCookie.toString()); 
            }

            bLoginBaiduOk = bAllCookiesFound;
                        
            if (bLoginBaiduOk)
            {
            	System.out.println("成功模拟登陆百度首页！" );
            }
            else
            {
            	System.out.println("模拟登陆百度首页 失败！");
            	System.out.println("所返回的HTML源码为：" + loginBaiduRespHtml);
            }

即可。

成功模拟登陆百度后的输出是：

Cookies for http://www.baidu.com/
[version: 0][name: BAIDUID][value: EB16BC3D9EB401EAD360D7F49C635382:FG=1][domain: .baidu.com][path: /][expiry: Thu Sep 17 17:49:06 CST 2043]

正确：已找到cookie BAIDUID

Baidu Password:

成功模拟登陆百度首页！

如图：

随后，再稍微整理一下代码去，即可。

【总结】

此处，java中模拟登陆百度访问login的url，没有获得所希望的返回的html和cookie，原因是：

自己粗心大意，导致忘了发送用户名和密码

所以必然登陆失败。

解决办法：

（1）传递对应的username和password，即可成功返回所希望的cookie；

（2）此处java中，将：

Set-Cookie: SAVEUSERID=deleted; expires=Mon, 17-Sep-2012 09:45:03 GMT; path=/; domain=passport.baidu.com; httponly,

解析后，丢掉了。

所以，java中，判断模拟登陆百度是否成功的检测cookie时，就不去判断对应的SAVEUSERID，只判断：BDUSS，PTOKEN，STOKEN即可。

（3）完整的，成功的，模拟登陆百度的代码，自己去看：
