使用python提交到Web表单 [英] Submitting to a web form using python

问题描述

我看过很多次这样的问题，但没有帮助

I have seen questions like this asked many many times but none are helpful

我正在尝试将数据提交到网络上已尝试的请求中的表单，而urllib却没有任何作用

Im trying to submit data to a form on the web ive tried requests, and urllib and none have worked

例如，下面的代码应在SO上搜索[python]标记:

for example here is code that should search for the [python] tag on SO:

import urllib
import urllib2

url = 'http://stackoverflow.com/'

# Prepare the data
values = {'q' : '[python]'}
data = urllib.urlencode(values)

# Send HTTP POST request
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)

html = response.read()

# Print the result
print html

但是，当我运行它时，我会得到主页的html信息

yet when i run it i get the html soure of the home page

这是使用请求的示例:

import requests

data= {
    'q': '[python]'
    }
r = requests.get('http://stackoverflow.com', data=data)

print r.text

相同的结果！我不明白为什么这些方法无法奏效，但我已经在各种站点上尝试了这些方法，但均未成功，因此，如果有人成功完成此操作，请告诉我如何做！

same result! i dont understand why these methods arent working i've tried them on various sites with no success so if anyone has successfully done this please show me how!

非常感谢！

推荐答案

如果您要使用q作为参数传递rel ="noreferrer"> requests ，请使用params参数，而不要使用data(请参见

If you want to pass q as a parameter in the URL using requests, use the params argument, not data (see Passing Parameters In URLs):

r = requests.get('http://stackoverflow.com', params=data)

这将请求 https://stackoverflow.com/?q=%5Bpython%5D ，不是您要找的东西.

This will request https://stackoverflow.com/?q=%5Bpython%5D , which isn't what you are looking for.

您真的想 POST 为表格.试试这个:

You really want to POST to a form. Try this:

r = requests.post('https://stackoverflow.com/search', data=data)

这与 GET -ting https://stackoverflow.com/questions基本相同/tagged/python ，但我想您会从中得到灵感的.

This is essentially the same as GET-ting https://stackoverflow.com/questions/tagged/python , but I think you'll get the idea from this.
