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http://login.sina.com.cn/sso/prelogin.php链接获取一些登陆需要参数,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}
,接下来是预登陆处理代码:
/** * @author LongJin * @description 初始登录信息
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http://login.sina.com.cn/sso/login.php,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:
新浪通行证 正在登录 ...
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)"; Listparms = new ArrayList (); 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。
以上就是本文的全部内容,希望本文的内容对大家的学习或者工作能带来一定的帮助,同时也希望多多支持创新互联!
