python-2.7 - 使用Python和Mechanize提交网站html中的数据

Question

我有 this网站有四个输入框，分别是Symbol , Expiry Date , From , To .现在我已经编写了一个代码来从 Symbol 中抓取数据和 Expiry Date是这样的:

import requests
import json
from bs4 import BeautifulSoup

r = requests.get("http://www.mcxindia.com/sitepages/BhavCopyCommodityWise.aspx")
soup = BeautifulSoup(r.content)
pop = []
pop_dates = []
count = 0
print soup.prettify()

option_list = soup.findAll("option")
#print option_list

for value in option_list:
    #print value
    if value.find(text = True):
        text = ''.join(value.find(text = True))
        text1 = text.encode('ascii')

        if count < 32:  
           pop.append(text1) 

    while count == 32 or count > 32:
        pop_dates.append(text1)
        break

    count = count + 1

print pop
print pop_dates

所以我想做的是 From和 To我想从我的代码中给出日期，它将接受该输入，在网站的 html 上使用它，并像往常一样在该网站中提供输出。我怎样才能做到这一点？？我听说 Mechanize 可以做这些东西，但在这种情况下我怎么能使用 Mechanize ？？

你可以尝试这样的事情:

from mechanize import Browser
from bs4 import BeautifulSoup

br = Browser()
br.set_handle_robots( False )
br.addheaders = [('User-agent', 'Firefox')]
br.open("http://www.mcxindia.com/sitepages/BhavCopyCommodityWise.aspx")
br.select_form("form1")
#now enter the dates according to your choice
br.form["mTbFromDate"] = "date-From"
br.form["mTbFromDate"] = "date-To"
response = br.submit()
#now read the response with BeautifulSoup and do whatever you want
soup = BeautifulSoup(response.read())
