21cn邮箱登陆

模拟21cn邮箱登陆

用抓包工具firebug(本人使用的也可以时别的),找到登陆页面分析出form表单,21cn登陆的页面url是:

http://open.e.189.cn/189mail/account/unifyAccountLogin.do?APPId=8013411507&version=v1.0&clientType=1&paras=C753AEA2F4A5B49F4CDB8FAA67B76EC6B7574A025C7762D4B6DF40517C089400A12B34FB306F67961C52F90B185E9D2C7C91EDA1D5B11ECCDCB6EC2E081060E34B9901761CBD9B3AC9654C6BC9A017CC5284E04EBEC9F4DF237F2E2E06E396BA5437FB665FEAE4C766ED22EDBE96383CFF858694C6148A8345A9C00695A3844735E4FF01FF0CC59FC1A62C672F9D3B168FE0AB271811A3EE5ECA0C342123FDF9B37CD271F748B2F33D6E3E28&sign=28E498416D78B2FEBED59826838D59B8EBFA374C&format=redirect

第一步:获得下一步post请求的需要的参数和cookies下面代码

//usename:为自己的用户名

//pwd为自己的邮箱密码

public static void login(String username, String pwd) {
    Map<String, String> cookies3 = null ;
    String str[] = new String[10];
    // 第一次请求
    // 获取链接
    String url = "http://open.e.189.cn/189mail/account/unifyAccountLogin.do?appId=8013411507&version=v1.0&clientType=1&paras=C753AEA2F4A5B49F4CDB8FAA67B76EC6B7574A025C7762D4B6DF40517C089400A12B34FB306F67961C52F90B185E9D2C7C91EDA1D5B11ECCDCB6EC2E081060E34B9901761CBD9B3AC9654C6BC9A017CC5284E04EBEC9F4DF237F2E2E06E396BA5437FB665FEAE4C766ED22EDBE96383CFF858694C6148A8345A9C00695A3844735E4FF01FF0CC59FC1A62C672F9D3B168FE0AB271811A3EE5ECA0C342123FDF9B37CD271F748B2F33D6E3E28&sign=28E498416D78B2FEBED59826838D59B8EBFA374C&format=redirect";

    Connection con = Jsoup.connect(url);
 con.header("User-Agent", "Mozilla/5.0 (X11; ubuntu; linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0");

    // 配置模拟浏览器)

    // 获取响应
    response rs;
    try {
        rs = con.execute();
        // System.out.println(rs.body());
        // Document doc=con.get();
        // 转换为dom
        Document dl = Jsoup.parse(rs.body());
        // 获取form表单，
        List<Element> et = dl.select("#loginForm");

        // 获取，cooking的表单属性。下面map存放post的数据
        Map<String, String> map = new HashMap<String, String>();

/* map.put(“userName”, username);

map.put(“password”,pwd);*/

for (Element e : et.get(0).getAllElements()) {

// e.attr(“name”).equals(“userName”）表示name标签的值

if (e.attr(“name”).equals(“userName”)) {

// 设置用户名

e.attr(“value”, username);

}

if (e.attr(“name”).equals(“password”)) {

// 设置用户密码

e.attr(“value”, pwd);

}

// 排除空值表单属性

if (e.attr(“name”).length() > 0) {

map.put(e.attr(“name”), e.attr(“value”));

}

}

int i = 0;
        for (Map.Entry<String, String> ele : map.entrySet()) {
        System.err.println(ele);
            str[i] = ele.getValue();
            i++;
        }

        //获取页面cookie
        Connection con1= Jsoup.connect("https://open.e.189.cn/api/common/loginSubmit.do?accountType="+str[5]+"&appId="+str[6]+"&returnUrl="+str[8]+"&clientType="+str[2]+"&userName="+str[9]+"%4021cn.com&mail="+str[3]+"&password="+str[1]+"&validateCode="+str[4]);
            con1.header("User-Agent", "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0");
                    Response response1 =  con1.ignorecontentType(true).method(Method.POST).data(map).execute();
                    //获取页面cookie
                Map<String, String> cookies = response1.cookies();
        }

第二部获取需要的一个cookie:LSID和下一步需要的url

Document doc=Jsoup.connect(“https://open.e.189.cn/api/common/loginSubmit.do?accountType=“+str[5]+”&appId=”+str[6]+”&returnUrl=”+str[8]+”&clientType=”+str[2]+”&userName=”+str[9]+”%4021cn.com&mail=”+str[3]+”&password=”+str[1]+”&ValidateCode=”+str[4]).get();

//获取请求以后的url

String toUrl1 = doc.baseUri().substring(doc.baseUri().indexof(“LSID”));

String toUrl2 = toUrl1.replace(“%3D”, “=”);

String toUrl3 = toUrl2.replace(“%26”, “&”);

String LSID = toUrl3.substring((toUrl3.indexOf(“LSID”)+5),(toUrl3.indexOf(“&”)));

                            cookies.put("LSID", LSID);
                    String toUrl  = "http://mail.21cn.com/w2/logon/unifyPlatformLogonReturn.do?"+toUrl3;



                    Connection con2= Jsoup.connect(toUrl);

                con2.header("User-Agent", "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0");
                    Response response2 = con2.ignoreContentType(true).method(Method.GET).cookies(cookies).execute();
                    Map<String, String> cookies2 = response2.cookies();

                    String [] str1 = new String[2];
                    int j =0;
                    for (Map.Entry<String, String> entry : cookies2.entrySet()) {

                        str1[j] = entry.getValue();
                        j++;
                    }

//第三部:进入主页

Connection con3 =Jsoup.connect(“http://mail.21cn.com/w2/logon/signOn.do“);

con3.header(“User-Agent”, “Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0”);

Response response3 = con3.ignoreContentType(true).method(Method.GET).cookies(cookies2).execute();

                    String str2 = response3.body();
                        //获取cookie
                     cookies3 = response3.cookies();
                        String cookie = "";
                    String cookie1 = "";
                    int count = 1;
                    for (Map.Entry<String, String> entry : cookies3.entrySet()) {
                        if(count <cookies3.size()){
                        cookie1 = entry.getKey() +"="+entry.getValue()+";";
                        }else{
                            cookie1 = entry.getKey() +"="+entry.getValue();
                        }
                        count++;
    cookie = cookie + cookie1;

                    }
if(cookies3.size() > 0){
                        System.out.println("登陆成功");
                        GetEmail.getEmail(cookie);(此方法为获取邮件和附件的方法,下面会有,GetEmail是类getEmail为此类的静态方法)

                    }else{
                        System.out.println("登录失败");
                    }



    } catch (Exception e1) {
