Введение:
Друзья, пришли, недавно кто-то спросил, как имитировать вход в新浪微博 для извлечения данных, после этого я默默 выкурил старую сигару, и тихо сказал себе, что время для тебя, старик, вышло, поэтому сегодня я решил привести в порядок и кратко рассказать о нем.
Прежде всего:
Чтобы войти в新浪微博， необходимо выполнить предварительный вход, то есть зашифровать аккаунт в base64, зашифровать пароль с помощью rsa и отправить запросhttp://login.sina.com.cn/sso/prelogin.phpПолучение некоторых параметров, необходимых для входа, возвращает строку, такую как:
{"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}
далее идет код обработки предвхода:
/**
* @author LongJin
* @description Начальные данные для входа<br> Возврат false означает, что начальная попытка失败了
* @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("Вскрыть исключение UnsupportedEncoding");
catch (ClientProtocolException e) {
System.out.println("В THROW ClientProtocolException");
} catch (IOException e) {
System.out.println("Исключение ввода-вывода");
}
return flag;
}
Далее:
Получите необходимые параметры для входа и используйте запрос POSThttp://login.sina.com.cn/sso/login.php<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：

Часть входа в систему завершена.
Теперь мы перейдем к тестированию входа в систему и извлечению данных:
public static void main(String[] args) throws ClientProtocolException, IOException {
SinaWeibo weibo = new SinaWeibo("**", "***"); // аккаунт и пароль не разглашаются
if(weibo.login()) {
System.out.println("登录成功！");
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？ ????
到此整个登录就完成了，望有不足之处多提点。
