Python小应用之火车路线查询

代码 def  getrain(f,t):
""" 获取火车路线，参数是from和to """
     url  = " / "

     form  =  urllib.urlencode([( ' chufa ' ,f),( ' daoda ' ,t)])

     req  =  urllib2.Request(url)

     fd  =  urllib2.urlopen(req,form)
     lines  =  fd.readlines()
     cars  =  str(lines[ 16 ])
     cars  =  cars.replace( " <b> " , "" )
     cars  =  cars.replace( " </b> " , "" )
     cars  =  cars.replace( " <br /> " , "" )
      print  cars.decode( " utf-8 " )
     lines  =  lines[ 20 : - 6 ]
     tmp  =   ""
      for  l   in  lines:
          tmp  =  tmp  +  l
     tmp  =  tmp.replace( " <br /> " , "" )
     tmp  =  tmp.replace( " <li> " , "" )
     tmp2  =  tmp.split( " \r\n\r\n " )
     tmp3  =  []
      for  i  in  tmp2:
          i  =  i.strip()
           if  i  ==   "" :
                continue
          pos1  =  i.rfind( " = " )  +   1
          pos2  =  i.rfind( ' " ' )
          cc  =   " 车次:%s "   %  i[pos1:pos2]
          i  =  i[i.find( " \n " , 2 ) + 1 :]
          i  =  cc  +   " \n "   +  i  +   " \r\n "
          tmp3.append(i)
     end  =   ""
      for  s  in  tmp3:
          end  =  end  +  s  +   " \n "
     end  =  cars  +  end  +   " \n "
      return  end

 

拿过去就可以用， 前面需要：

import string

import urllib

import urllib2

import sys

 

主要思路：

1、就是找个wap查询火车的网站，发现还不错

2、抓包，看到post的数据

3、然后在模拟提交，下载

 4、解析，输出

 

拿过去就可以用，输出已经做过处理
