在javascrip的特定表单上使用Python mechanize

Question

我尝试使用Python mechanize模块通过以下形式检索数据：http://archive.stsci.edu/kepler/data_search/search.php?form=fuf

我遇到的问题是左下角的“Output Columns”区域，它使用javascript指定输出格式。我希望能够选择一个特定的项目列表，这通常是通过周围的javascript按钮来选择的。在

我刚开始机械化，很久没看过javascript了。我已经看过了负责的javascript，但不知道该怎么做。有什么提示吗？在

更具体地说：有没有一种方法可以使用mechanize来修改列表中的元素？在

Answer 1

我建议直接对该表单进行POST调用，而不是通过mechanize与表单进行交互。下面是我如何使用mechanize：

import mechanize
from urllib import urlencode
opener = mechanize.build_opener()
data = {"resolver":"NED","radius":"0.02","equinox":"J2000","ktc_target_type[]":"LC","ktc_target_type[]":"SC","extra_column_name_1":"ktc_kepler_id","extra_column_value_1":"","extra_column_name_2":"ktc_kepler_id","extra_column_value_2":"","extra_column_name_3":"ktc_kepler_id","extra_column_value_3":"","extra_column_name_4":"ktc_kepler_id","extra_column_value_4":"","selectedColumnsCsv":"Mark,ktc_kepler_id,ktc_investigation_id,sci_data_set_name,ktc_target_type","selectedColumnsList[]":"ktc_target_type","availableColumns":"Mark","ordercolumn1":"ang_sep","ordercolumn2":"ktc_kepler_id","ordercolumn3":"","coordformat":"sex","outputformat":"HTML_Table","max_records":"1001","max_rpp":"100","action":"Search"}
d = urlencode(data)
url = 'http://archive.stsci.edu/kepler/data_search/search.php'
stuff = opener.open(url,d)
info_i_want = stuff.read()

基本上，把你的搜索内容放到字典里，给服务器打一个POST调用，然后读你的响应。在
