按网页按钮 [英] Pressing A Webpage Button
问题描述
如何让Python按下网页上的按钮？我查看了
urllib，但我只看到如何用它打开一个URL。我搜索了
谷歌但没有运气。
例如，谷歌有一个按钮< input type = submit value =" Google
搜索命名= btnG>我如何制作一个脚本按下那个按钮？
只是为了好玩，有没有办法相当于输入一个
文本字段就好了在点击按钮之前的谷歌搜索字段？
（我实际上并不需要这样做。）
如果有人可以指出我在右边我们将不胜感激。

How do I make Python press a button on a webpage? I looked at
urllib, but I only see how to open a URL with that. I searched
google but no luck.
For example, google has a button <input type=submit value="Google
Search" name=btnG> how would i make a script to press that button?
Just for fun, is there any way to do the equivalent of typing into a
text field like the google search field before hitting the button?
(I don''t actually need to do this.)
If someone could point me in the right direction it''d be appreciated.

你真的需要''按''按钮吗？或者你只需按下按钮会带来的
效果（例如，提交一个
Google搜索查询并收到结果页面）？
如果是后者，那么你可能想要搜索，例如html form get
post并查看一些结果。按下按钮通常只是
加载带参数的URL。
例如，转到Google并输入html form get post;进入搜索
框并按提交。现在查看您在
位置栏中访问的网址，即搜索结果的网址。它将类似于：
http://www.google.com/search?hl=en&q...=Google+Search
如果您要直接加载该网址（没有转到
Google主页，请在文字输入框中输入html表格获取帖子并按
按提交）将发生完全相同的效果。在框中填写
并单击提交按钮只是构建该URL的用户友好方式
。
Do you actually need to ''press'' the button? Or do you just need the
effect that pressing the button would bring about (e.g., submitting a
Google search query and receiving the results page)?
If the latter, then you might want to search for, e.g., "html form get
post" and check out some results. Pushing the button is often just
loading a URL with parameters.
For example, go to Google and type "html form get post" into the search
box and press Submit. Now look at the URL you are visiting in your
location bar, the URL of the search results. It will be something like:
http://www.google.com/search?hl=en&q...=Google+Search
If you were to load that URL directly (without having gone to the
Google homepage, typed "html form get post" in the text entry box and
pressed submit) the exact same effect would happen. Filling in the box
and clicking the submit button is just the user-friendly way of
constructing that URL.

你不知道哪个操作系统...如果你是你在Windows上运行IE
可以使用COM如下...
来自win32com.client import Dispatch
来自导入时间睡觉
ie = Dispatch（InternetExplorer.Application）
ie.Visible = 1
ie.Navigate（" ; http：//www.google.com"）
而ie.ReadyState！= 4：＃等待浏览器完成加载。
sleep（1）
doc = ie.Document
doc.fqvalue =" qwerty" #form name是''f'';搜索字段名称为''q''
doc.f.btnG.click（）＃点击按钮''btnG''
You don''t say which OS... if you''re running IE on Windows you
can use COM as follows...
from win32com.client import Dispatch
from time import sleep
ie = Dispatch("InternetExplorer.Application")
ie.Visible = 1
ie.Navigate("http://www.google.com")
while ie.ReadyState != 4: # Wait for browser to finish loading.
sleep(1)
doc = ie.Document
doc.f.q.value = "qwerty" # form name is ''f''; search field name is ''q''
doc.f.btnG.click() # click on button ''btnG''
