Java, um den Login von Sina Weibo zu simulieren und Daten abzurufen

Vorwort:

Brüder, hier ist es! Lately, someone asked me how to simulate the login of Sina Weibo to capture data. After hearing this, I silently took a puff of an old cigarette and whispered to myself, it's time for you, old man, to make an appearance. So today, I took some time to organize and discuss a few points.

Erstens:

Um sich bei Sina Weibo anzumelden, ist eine Voranmeldung erforderlich, d.h. die Base64-Kodierung des Kontos64Verschlüsselung, RSA-Verschlüsselung des Passworts sowie der Anfragehttp://login.sina.com.cn/sso/prelogin.phpUm einige Parameter zu erhalten, die für die Anmeldung erforderlich sind, wird eine Verbindung hergestellt und der zurückgegebene String wie folgt ist:

{"retcode":0, "servertime":1487292003,"pcid":"gz"-9e1f24c9acdefb111e1c8078558c7d9c0bf2", "nonce":"VHRDG"1", "pubkey":"EB"2A38568661887FA180BDDB5CABD5F21C7BFD59C090CB2D245A87AC253062882729293E5506350508E7F9AA3BB77F4333231490F915F6D63C55FE2F08A49B353F444AD3993CACC02DB784ABBB8E42A9B1BBFFFB38BE18D78E87A0E41B9B8F73A928EE0CCEE1F6739884B9777E4FE9E88A1BBE495927AC4A799B3181D6442443", "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}

Next comes the pre-login processing code:

/**
 * @author LongJin
 * @description Initial Login Information<br> Returning false indicates initial failure
 * @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("UnsupportedEncoding-Exception wird ausgelöst");
 } catch (ClientProtocolException e) {
 System.out.println("抛出ClientProtocol异常");
 } catch (IOException e) {
 System.out.println("抛出IO异常");
 }
 return flag;
 }

Zweitens:

Nachdem die Parameter für die Anmeldung erhalten wurden, wird eine POST-Anfrage verwendethttp://login.sina.com.cn/sso/login.phpDie oben genannten Daten, die nach der Voranmeldung verarbeitet werden, werden als Parameter in die Anfrage eingefügt und das folgende Ergebnis erhalten:

<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，登录部分的代码如下：

/**
 * @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"));
 parms.add(new BasicNameValuePair("geteway", ""));1"));
 parms.add(new BasicNameValuePair("from", ""));
 parms.add(new BasicNameValuePair("savestate", ""));7"));
 parms.add(new BasicNameValuePair("useticket", ""));1"));
 parms.add(new BasicNameValuePair("pagerefer", "http:"));//login.sina.com.cn/sso/logout.php?entry=miniblog&r=http%3A%2F%2Fweibo.com%2Flogout.php%3Fbackurl%3D%2F"));
 parms.add(new BasicNameValuePair("vsnf", ""));1"));
 parms.add(new BasicNameValuePair("su", su));
 parms.add(new BasicNameValuePair("service", "miniblog"));
 parms.add(new BasicNameValuePair("servertime", servertime)); + ""));
 parms.add(new BasicNameValuePair("nonce", nonce));
 parms.add(new BasicNameValuePair("pwencode", "rsa"));2"));
 parms.add(new BasicNameValuePair("rsakv", rsakv));
 parms.add(new BasicNameValuePair("sp", sp));
 parms.add(new BasicNameValuePair("encoding", "UTF-8"));
 parms.add(new BasicNameValuePair("prelt", "182"));
 parms.add(new BasicNameValuePair("url", "http://weibo.com/ajaxlogin.php?framelogin=1&callback=parent.sinaSSOController.feedBackUrlCallBack"));
 parms.add(new BasicNameValuePair("domain", "sina.com.cn"));
 parms.add(new BasicNameValuePair("returntype", "META"));
 try {
 String content = HttpUtils.postRequest(client, url, parms);
 System.out.println("content----------" + content);
 String regex = "location.replace\\('([\\s\\S*?);)'\\);";//\\(' '\\)Besondere Zeichen umwandeln und den Inhalt im Pfeil (''') matchen//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=")) {//Wenn du bis hierher gekommen bist, gratuliere, du hast einen Fehler gemeldet
  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：

Der Anmeldeabschnitt ist im Grunde abgeschlossen.

Zuletzt führen wir den Test der Anmelde- und Datenabholung durch:

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);也可以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--------------我选择了"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送给篮协。本赛季本土MVP是谁？ ????

至此整个登录过程就完成了，希望有不足之处多多提出。
