自动定时post

需求分析
第一步：fiddler抓包
第二步：编写java提交post
第三步：部署到服务器上定时运行
结语

需求分析

需求：实现发请求、签到自动化，每天定时提交，邮件提示结果，告别手动。（使用应当合理合法！）
案板上有：1台vps,linux centos7+fiddler抓包工具+jar包。
实现：先用fiddler抓包工具抓取提交打卡是的HTTP请求，再分析每天不同的地方，仿照着利用Java编写脚本发送类似请求，安排到服务器上设置一个定时任务就完事了。（以前做过用python+appuim现在想想真的憨憨。。）

第一步：fiddler抓包

注：涉及隐私部分用xxxxxx替代

POST https:xxxxxxxxxxxx HTTP/1.1

可以看到打卡提交了一个带着json的post请求，接下来需要编写Java代码实现模拟post提交json数据。

第二步：编写java提交post

        }catch (Exception e){
            e.printStackTrace();
        }
        return false;
    }


    public static void main(String[] args) {




        //先打卡
        Date date = new Date();
        DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
        String format = dateFormat.format(date);

         String TBRQ = format;
         String TXJTSJ = format+" 00:08:26";


        String GUID = "xxxxx";
        String XH="xxxxx";
        String XM= "xxxxx";
        String BKBJ = "xxxxxx";
        String LoginUserID ="xxxxxxx";

        String strjson = "{\"main\":[{\"TableName\":\"T_YQFKTJ\",\"Data\":[{\"GUID\":\""+GUID+"\",\"TBRQ\":\""+TBRQ+"\",\"TXJTSJ\":\""+TXJTSJ+"\",\"XH\":\""+XH+"\",\"XM\":\""+XM+"\",\"SZXY\":\"xxxxxxx\",\"BKYJS\":\"xxxx\",\"SZX\":\"\",\"BKBJ\":\""+BKBJ+"\",\"YJSBJ\":\"\",\"SS\":\"xxxxx\",\"HQCS\":\"xxxxxx\",\"TBWD\":\"\",\"KQWD\":\"xxxxxx\",\"JYDD\":\"\",\"SFWQZBLYYZDWQZ\":\"否\",\"MQSTQK\":\"\",\"SFWYSBLYYZDWYS\":\"否\",\"YSJYDD\":\"\",\"SFWJZGL\":\"未曾隔离\",\"JZGLKSSJ\":\"\",\"JZGLJSSJ\":\"\",\"TNSFYQZBRYGMQJC\":\"否\",\"QZBRJCDDSSX\":\"\",\"TNSFZHBZZHTJHBYHB\":\"否\",\"FHYY2\":\"\",\"SFJRDH\":\"否\",\"QTXCGSJ\":\"\",\"SFDHZQTXQ\":\"否\",\"JJTZYQGLSJ\":\"\",\"SFWJJGL\":\"无\",\"TNSFDDLKHZTJWZWLHYSD\":\"否\",\"FHYY1\":\"\",\"LQHZJKMQK\":\"已领取“绿码“\",\"JSSTSFYJWRYJC\":\"否\",\"JZGLDD\":\"\",\"YSMQSTQK\":\"未缺课\",\"JZBHBMTZGL\":\"未离校\",\"JJGLYY\":\"未离杭\",\"JZLXDH\":\"\",\"JJGLKSSJ\":\"\",\"JJGLJSSJ\":\"\",\"JJLXDH\":\"\",\"QZBRJCSJ\":\"\",\"QZBRJCFS\":\"\",\"DDHBRQ\":\"\",\"LKHZTJHBRQ\":\"\",\"JCRQ\":\"\",\"DDWZRQ\":\"\",\"ZZHZTJWZRQ\":\"\",\"DDWLHZHYRQ\":\"\",\"ZZHZTJWLRQ\":\"\",\"FHSJ2\":\"\",\"RZYHJCYSQTXZYSJJCYSSJ\":\"\",\"RZYYSJC\":\"\"}],\"TableId\":\"xxxxxx\"}],\"sub\":[],\"LoginUserID\":\""+LoginUserID+"\",\"GUID\":\""+GUID+"\",\"FORMID\":\"xxxxxxxxxxx\"}";

        //用到了fastjson-1.2.74.jar

            send("抓包到的网址",jsonobj);
        } catch (Exception e) {//防止偶然的连接reset
            send("抓包到的网址",jsonobj);

        //System.out.println(sendmail);

        sendMail("xxxxx@qq.com", sendmail, "打卡结果！");
    }
 
}

第三步：部署到服务器上定时运行

①确认Linux环境。

确保系统时间为北京时间。
确保java环境配置完毕。
确保xshell连接正常。

②上传所需jar和写好的Java文件到Linux

用到的jar包有

	activation-1.1.jar，
	fastjson-1.2.74.jar，
	javax.mail-1.6.0.jar，

以及写好的程序daka.java

在xshell连接下用rz命令上传到目录

	/root/mylearn/webapp/daka

③操作权限解决：

修改使用文件夹的操作权限

	sudo chmod -R 777 /root/mylearn/webapp/daka

④Linux下带jar包编译与运行Java程序

jar包之间用:隔开，最后也要加。

javac -cp /root/mylearn/webapp/daka/libs/activation-1.1.jar:/root/mylearn/webapp/daka/libs/fastjson-1.2.74.jar:/root/mylearn/webapp/daka/libs/javax.mail-1.6.0.jar: /root/mylearn/webapp/daka/daka.java

得到class文件后，运行如下。

java -cp /root/mylearn/webapp/daka/libs/activation-1.1.jar:/root/mylearn/webapp/daka/libs/fastjson-1.2.74.jar:/root/mylearn/webapp/daka/libs/javax.mail-1.6.0.jar: daka

⑤写sh脚本并且配置定时运行

写sh脚本

vi daka.sh

按i进入编辑，粘贴如下，：x保存退出。

#!/bin/bash
cd /root/mylearn/webapp/daka
java -cp /root/mylearn/webapp/daka/libs/activation-1.1.jar:/root/mylearn/webapp/daka/libs/fastjson-1.2.74.jar:/root/mylearn/webapp/daka/libs/javax.mail-1.6.0.jar: daka

配置定时

vi /etc/crontab

#改类似定时，这里设置00：10分打卡
 10 00 * * * root /root/mylearn/webapp/daka/daka.sh

装载

 crontab /etc/crontab

重启定时服务

systemctl enable crond.service #开启启动
systemctl restart crond.service #重启服务

结语

前几个月暑假无聊用python+appuim弄过一个自己打卡的脚本，就是滚屏幕模拟点击的那种。想把它部署到服务器，发现不现实，后来想到他打卡不就是个提交表单嘛，不就是个post嘛。所以搞了个这个，以后不用自己打卡了嘿嘿嘿！
