前言:
兄弟们来了来了，最近有人在问如何模拟新浪微博登陆抓取数据，我听后默默地抽了一口老烟，暗暗的对自己说，老汉是时候该你出场了，所以今天有时间就整理整理，浅谈一二。
首先：
要想登陆新浪微博需要预登陆，即是将账号base64加密，密码rsa加密以及请求链接获取一些登陆需要参数，返回的接送字符串如：
我要评论
{"retcode":0,"servertime":1487292003,"pcid":"gz-9e1f24c9acdefb111e1c8078558c7d9c0bf2","nonce":"vhrdg1","pubkey":"eb2a38568661887fa180bddb5cabd5f21c7bfd59c090cb2d245a87ac253062882729293e5506350508e7f9aa3bb77f4333231490f915f6d63c55fe2f08a49b353f444ad3993cacc02db784abbb8e42a9b1bbfffb38be18d78e87a0e41b9b8f73a928ee0ccee1f6739884b9777e4fe9e88a1bbe495927ac4a799b3181d6442443","rsakv":"1330428213","is_openlock":0,"lm":1,"smsurl":"https:\/\/login.sina.com.cn\/sso\/msglogin?entry=weibo&mobile=18360903574&s=ea7a2e91c5f1d6da7f42aa87fe6963d0","showpin":0,"exectime":222}
，接下来是预登陆处理代码：
/**
* @author longjin
* @description 初始登录信息<br> 返回false说明初始失败
* @return
*/
public boolean prelogin(){
boolean flag = false;
try {
su = new string(base64.encodebase64(urlencoder.encode(username, "utf-8").getbytes()));
string url = "http://login.sina.com.cn/sso/prelogin.php?entry=weibo&rsakt=mod&checkpin=1&" +
"client=ssologin.js(v1.4.5)&_=" + gettimestamp();
url += "&su=" + su;
string content;
content = httputils.getrequest(client, url);
system.out.println("content------------" + content);
jsonobject json = jsonobject.fromobject(content);
system.out.println(json);
servertime = json.getlong("servertime");
nonce = json.getstring("nonce");
rsakv = json.getstring("rsakv");
pubkey = json.getstring("pubkey");
flag = encodepwd();
} catch (unsupportedencodingexception e) {
system.out.println("抛出unsupportedencoding异常");
} catch (clientprotocolexception e) {
system.out.println("抛出clientprotocol异常");
} catch (ioexception e) {
system.out.println("抛出io异常");
}
return flag;
}
其次：
获取登陆需要的参数后使用post请求，将上述预登陆后处理数据作为参数代入请求，得到结果如下：
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=gbk" />
<title>新浪通行证</title>
<script charset="utf-8" src="http://i.sso.sina.com.cn/js/ssologin.js"></script>
</head>
<body>
正在登录 ...
<script>
try{sinassocontroller.setcrossdomainurllist({"retcode":0,"arrurl":["http:\/\/passport.97973.com\/sso\/crossdomain?action=login&savestate=1518828005","http:\/\/passport.weibo.cn\/sso\/crossdomain?action=login&savestate=1"]});}
catch(e){
var msg = e.message;
var img = new image();
var type = 1;
img.src = 'http://login.sina.com.cn/sso/debuglog?msg=' + msg +'&type=' + type;
}try{sinassocontroller.crossdomainaction('login',function(){location.replace('http://passport.weibo.com/wbsso/login?ssosavestate=1518828005&url=http%3a%2f%2fweibo.com%2fajaxlogin.php%3fframelogin%3d1%26callback%3dparent.sinassocontroller.feedbackurlcallback&ticket=st-ntuwodg3mjkxmq==-1487292005-gz-ff56c545999f864fc6c7ab86fca9fa4a-1&retcode=0');});}
catch(e){
var msg = e.message;
var img = new image();
var type = 2;
img.src = 'http://login.sina.com.cn/sso/debuglog?msg=' + msg +'&type=' + type;
}
</script>
</body>
</html>
然后用正则截取其中我们想要的部分：location.replace（''）中间部分，正则表达式为：
string regex = "location.replace\\('([\\s\\s]*?)'\\);";
将正则得到的结果进行处理，如果成功则使用get请求得到的链接，登陆部分的代码如下：
/**
* @author longjin
* @description 登录
* @return true:登录成功
*/
public boolean login() {
if(prelogin()) {
string url = "http://login.sina.com.cn/sso/login.php?client=ssologin.js(v1.4.15)";
list<namevaluepair> parms = new arraylist<namevaluepair>();
parms.add(new basicnamevaluepair("entry", "weibo"));

try {
string content = httputils.postrequest(client, url, parms);
system.out.println("content----------" + content);
string regex = "location.replace\\('([\\s\\s]*?)'\\);";//\\(' '\\)特殊符转译 匹配（''）里面的内容//location.replace([\\s\\s]*?)
pattern p = pattern.compile(regex);
matcher m = p.matcher(content);
if(m.find()) {
system.out.println("ss = "+m.group());
location = m.group(1);
if(location.contains("reason=")) {//如果你走进了这一步，恭喜报错了
errinfo = location.substring(location.indexof("reason=") + 7);
errinfo = urldecoder.decode(errinfo, "gbk");
} else {
system.out.println("location = "+location);
string result = httputils.getrequest(client, location);//.substring(2, location.length()-2)
int beginindex = result.indexof("(");
int endindex = result.lastindexof(")");
result = result.substring(beginindex+1, endindex);//截取括号里面的json字符串
//content = urldecoder.decode(content, "utf-8");
jsonobject jsonobject = jsonobject.fromobject(result);//转换为json
//获取uniqueid+userdomain用于访问时带的参数
uniqueid = jsonobject.getjsonobject("userinfo").getstring("uniqueid");
userdomain = jsonobject.getjsonobject("userinfo").getstring("userdomain");
system.out.println("result--------------" + result);
return true;
}
}
} catch (clientprotocolexception e) {
system.out.println("抛出clientprotocol异常");
} catch (ioexception e) {
system.out.println("抛出io异常");
}
}
return false;
}
补充一下密码加密部分的代码：

登陆部分就基本完成了。
最后来进行测试登陆抓取数据：
public static void main(string[] args) throws clientprotocolexception, ioexception {
sinaweibo weibo = new sinaweibo("**", "***");//账号密码在此就不透露了
if(weibo.login()) {
system.out.println("登陆成功！");
inputstream con= httputils.getrequests(client, "http://weibo.com/u/"+uniqueid+userdomain);//请求个人主页获取输入流
string cont = readstreambyencoding(con, "utf-8");//将返回的输入流转换为字符串
string sb =httputils.gettext(cont);//通过jsoup获取text内容部分
//readstreamoutfilebyencoding(sb);也可已将获取的内容写入文件中
} else {
system.out.println("登录失败！");
}
}
得到的结果为：
text--------------我投给了"易建联" 这个选项。 #本土mvp# 本赛季常规赛最有价值球员（mvp）评选小组由中国篮协新闻委员会成员单位代表、俱乐部推荐的地方媒体代表组成，新浪拥有一票，我们将把粉丝们的意见发给篮协。 r本赛季本土mvp是？ ????
到此整个登陆就完成了，望有不足之处多提点。
