我正在尝试从网站下载 Excel 文件。 我使用 mechanize 成功填写了表格，提交表格后应该会返回文件下载。 但在下载时，它返回的是 html，而不是文件的实际内容。
import mechanize
br = mechanize.Browser()
br.open("http://web.sba.gov/pro-net/search/dsp_dsbs.cfm")
br.select_form('SearchForm')
br["States"] = ["AL","AK"]
br["E8a"] = ["Y"]
br["Report"] = ["S"]
response = br.submit()
fileobj = open("szz.txt","wb")
fileobj.write(response.read())
fileobj.close()
结果看起来像
<!doctype html>
<html lang="en-US" dir="ltr">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=Edge">
<title>SBA - Dynamic Search</title>
<link href="/gls/dsp_choosefunction.cfm" accesskey="1" rel="Home" title="Home (Return to GLS Choose Function)">

最佳答案
我在您的代码中发现了一些错误，我尝试了以下代码并在浏览器中打开文件显示了一个漂亮的表格，所以请尝试一下:
import mechanize
br = mechanize.Browser()
br.open("http://web.sba.gov/pro-net/search/dsp_dsbs.cfm")
br.select_form('SearchForm')
br.form["State"] = ["AL","AK"]
br.form["E8a"] = ["Y"]
br.form["Report"] = ["S"]
response = br.submit()
fileobj = open("szz.html","wb")
fileobj.write(response.read())
fileobj.close()
基本上，您需要调用br.form[control_name]，并且您在“States”键上犯了一个错误，它只是“State”，现在将文件另存为.html 并在浏览器中打开它，看看这是否是您正在寻找的内容。
