python mechanize-从aspnetForm submitControl检索触发文件下载的文件

当我不知道文件URL或文件名时，如何使用python mechanize从aspnetForm submitControl检索文件，该控件会触发Excel文件下载

包含Excel文件的站点的URL:

我正在尝试通过打印Excel“按钮”下载文件

到目前为止，我已经：

r = br.open('http://www.ncysaclassic.com/TTSchedules.aspx?tid=NCFL&year=2012&stid=NCFL&syear=2012&div=U11M01')
html = r.read()

# Show the html title
print br.title()

# Show the available forms
for f in br.forms():
    print f

br.select_form('aspnetForm')
print '\n\nSubmitting...\n'
br.submit("ctl00$ContentPlaceHolder1$btnExtractSched")

print 'Response...\n'
print br.response().info()
print br.response().read

print 'still alive...\n'

for prop, value in vars(br.response()).iteritems():
    print 'Property:', prop, ', Value: ', value

print 'myfile...\n' 

myfile = br.response().read

我得到这个输出：

    Submitting...

    Response...

我想我的br.response中已经有了这个文件。我只是不知道如何提取它！请帮助。

我似乎离得越来越近了……这两种方法对我都很有效：print'\n尝试编写文件1…\n'#在这里找到它#open（“/path/to/someFile”，“wb”）.write（urllib2.urlopen”（）open（“C:\Users\gregb\Downloads\download.xls”，“wb”）.write（br.response（）.read（））打印“\n尝试写入文件2…\n”打开（“C:\Users\gregb\Downloads\urlib2\u urlopen.xls”，“wb”）。写入（urlib2.urlopen（“）为什么我不能在这些评论中输入回车符？当我输入回车符时，我的评论在我完成之前就提交了！让我们试试帮助中建议的两个空格。让我们再试一次。这会开始一行新的内容吗？在IE上试一下，而不是Chrome。我本来打算在评论中发布我的代码，但是如果我不能输入换行符，那就很难了……让我试试标记格式化…

#这很有效！#打开一个本地文件实例fileobj=open（“C:\\Users\\gregb\\Downloads\\ncysa\u schedule.xls”，“w+”）#从fileobj.write（br.response（）.read（））fileobj.close（）上面的提交响应写入它。

你知道如何隐藏gzip（True）警告吗？

br.set\u handle\u gzip（True）#这会给出警告-如何抑制它？

br.set_handle_gzip（True）#这会给出警告-如何抑制它`

# fill out the form
response = br.submit()
fileobj = open('filename', 'w+')
fileobj.write(response.read())
fileobj.close()

# fill out the form
response = br.submit()
fileobj = open('filename', 'w+')
fileobj.write(response.read())
fileobj.close()
