Question

我想自动化一个过程，在我的服务器上使用Python搜索搜索栏中的关键字。但是，首先搜索会返回 免责声明 ，一旦接受，就会显示结果。免责声明网站如下：

http://emma.msrb.org/Disclaimer.aspx

我已经检查了网站，这是我的初步代码：

browser = RoboBrowser(history=True)
browser.open(tradeinfo) 
# tradeinfo = link to search result, i.e. http://emma.msrb.org/SecurityDetails/TradeActivity/ABF6AA894523779EDC8B751EB99959934
form = browser.get_forms()[0]
print form

<RoboForm __VIEWSTATE=somevalue, __VIEWSTATEGENERATOR=somevalue, __EVENTVALIDATION=somevalue, 
ctl00$Masthead$UserAcct1$NextAction=, 
ctl00$Masthead$UserAcct1$isPilotUser=False, ctl00$Masthead$searchTextBox=Enter CUSIP or Name,
ctl00$Masthead$headerSearchButton=, 
ctl00$mainContentArea$disclaimerContent$yesButton=, 
ctl00$mainContentArea$disclaimerContent$noButton=>
# Somevalue represents a string of characters (deleted for visual clarity)

然后我执行以下操作：

form['ctl00$mainContentArea$disclaimerContent$yesButton'].value ='Yes'
browser.submit_form(form)
browser.select('body')

但是身体仍然不包含数据。我也试过机械化，结果相同。有没有办法在没有Selenium的情况下使用机械化或RoboBrowser？如果是这样，我在剧本中遗漏的是什么？

P.S：“接受”按钮的html脚本：

<input type="image" 
name="ctl00$mainContentArea$disclaimerContent$yesButton" 
id="ctl00_mainContentArea_disclaimerContent_yesButton" 
data-jquerymobilestyle="false" 
src="images/btnAccept.gif" alt="Accept" style="border-width:0px;">

Answer 1

您只需发布数据，一个使用requests发布的示例和bs4来解析返回的内容：

In [6]: from bs4 import BeautifulSoup

In [7]: with requests.Session() as s:
   ...:         r = s.post("http://emma.msrb.org/Main/QuickSearch", data={"quickSearchText":"G-12"})
   ...:         soup = BeautifulSoup(r.content)
   ...:         print(soup.select_one("#ctl00_mainContentArea_SearchResultsControl1_searchResultsGridView"))
   ...:     
<table border="0" cellspacing="0" class="grid1" id="ctl00_mainContentArea_SearchResultsControl1_searchResultsGridView" width="100%">
<tr>
