最近在老家出差，老家电网改革，使用了智能电表，把老式电表全部换了还给了一个客户号，
终于也可以在支付宝什么的交电费了，但我们那里支付宝还不能查询剩余多少钱，这让人很恼火，
于是就来国家电网http://www.95598.cn/person/index.shtml 查询了一下，发现需要客户号、查询密码、验证码，客户号我知道，查询密码是不知道的，随便输入，提示错误，
于是打95598问了下客服，得知了默认密码是6个8，查询了一下，出来消息了，但想每次都上电脑上查，貌似有点不方便，就想自己做一个模拟提交的，
模拟提交就要解决验证码识别的问题，看看也不复杂，就捣鼓了一会，然后分析提交的信息及url，
然后看到一个http://www.95598.cn/95598/per/shortCut/getShortCutAccount 这个地址，只传了2个参数，一个客户号，还有一个不知道是什么，
就直接测试了下这个url，post提交了两个参数，然后居然信息直接出来了，
还是josn格式。。。客户名称、电表地址、电表号，余额、违约金、欠费信息，还有部分类型的客户居然还带近期的电费记录，
到这我就想问特么你之前验证的查询密码和验证码了 干什么用的？ 只是个慌子吗？我书都的少，你别骗我，這么大一个国家电网，居然这个查询密码是个渣？
好吧 代码我也上上来吧，但没什么技术含量了

示例中部分信息被我用xx代替了，
字段说明:
consN(客户号)、consName(客户姓名)、elecAddr(电表地址)、consSortCode类型、 acctBal(账户余额)、oweAmtSum(账户欠费)、
statusCode 固定为200 不管客户号有没有都是200 然后就是billInfo消息中如果consNo（客户号）为null则表示没有客户，
农村的返回稍微有点一样，但关键信息都有，今天不捣鼓了，洗洗睡了
