Java模擬新浪微博登陸抓取數據

前言:

兄弟們來了來了，最近有人在問如何模擬新浪微博登陸抓取數據，我聽后默默地抽了一口老煙，暗暗的對自己說，老漢是時候該你出場了，所以今天有時間就整理整理，淺談一二。

首先：

要想登陸新浪微博需要預登陸，即是將賬號base64加密，密碼rsa加密以及請求http://login.sina.com.cn/sso/prelogin.php鏈接獲取一些登陸需要參數，返回的接送字符串如：

{"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}

，接下來是預登陸處理代碼：

/**
 * @author LongJin
 * @description 初始登錄信息<br> 返回false說明初始失敗
 * @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("拋出UnsupportedEncoding異常");
 } catch (ClientProtocolException e) {
 System.out.println("拋出ClientProtocol異常");
 } catch (IOException e) {
 System.out.println("拋出IO異常");
 }
 return flag;
 }

其次：

獲取登陸需要的參數后使用post請求http://login.sina.com.cn/sso/login.php，將上述預登陸后處理數據作為參數代入請求，得到結果如下：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK" />
<title>新浪通行證</title>
<script charset="utf-8" src="http://i.sso.sina.com.cn/js/ssologin.js"></script>
</head>
<body>
正在登錄 ...
<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>

然后用正則截取其中我們想要的部分：location.replace（''）中間部分，正則表達式為：

String regex = "location.replace\\('([\\s\\S]*?)'\\);";

將正則得到的結果進行處理，如果成功則使用get請求得到的鏈接，登陸部分的代碼如下：

/**
 * @author LongJin
 * @description 登錄
 * @return true:登錄成功
 */
 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", "rsa2"));
 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]*?)'\\);";//\\(' '\\)特殊符轉譯 匹配（''）里面的內容//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=")) {//如果你走進了這一步，恭喜報錯了
  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);//截取括號里面的json字符串
  //content = URLDecoder.decode(content, "UTF-8");
  JSONObject jsonObject = JSONObject.fromObject(result);//轉換為json
  //獲取uniqueid+userdomain用于訪問時帶的參數
  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("拋出ClientProtocol異常");
 } catch (IOException e) {
 System.out.println("拋出IO異常");
 }
 }
 return false;
 }

補充一下密碼加密部分的代碼：

登陸部分就基本完成了。

最后來進行測試登陸抓取數據：

public static void main(String[] args) throws ClientProtocolException, IOException {
 SinaWeibo weibo = new SinaWeibo("**", "***");//賬號密碼在此就不透露了
 if(weibo.login()) {
 System.out.println("登陸成功！");
 InputStream con= HttpUtils.getRequests(client, "http://weibo.com/u/"+uniqueid+userdomain);//請求個人主頁獲取輸入流
 String cont = readStreamByEncoding(con, "UTF-8");//將返回的輸入流轉換為字符串
 String sb =HttpUtils.getText(cont);//通過jsoup獲取text內容部分
 //readStreamOutFileByEncoding(sb);也可已將獲取的內容寫入文件中
 } else {
 System.out.println("登錄失敗！");
 } 
 }

得到的結果為：

text--------------我投給了"易建聯" 這個選項。 #本土MVP# 本賽季常規賽最有價值球員（MVP）評選小組由中國籃協新聞委員會成員單位代表、俱樂部推薦的地方媒體代表組成，新浪擁有一票，我們將把粉絲們的意見發給籃協。 R本賽季本土MVP是？ ????

Java模擬新浪微博登陸抓取數據

到此整個登陸就完成了，望有不足之處多提點。
