使用Mechanize（python包）将文件添加到表单不起作用
我正在使用Mechanize for Python和webcarping一个Ticket的Web服务器（我们托管我们公司的故障/事件）我希望通过文件上传自动化它，在该文件中告知要添加的新票证到数据库。
就在最后，当上传文件时，它似乎在上传时中断。我试图通过两种方式上传不兼容类型的票证，首先通过Chromium，它发现了一个错误。当我对Mechanize做同样的事情时，错误没有显示，就像按钮＆＃34;提交＆＃34;点击没有任何文件。
我可以看到print br.form文件上传的时间..不知道它为什么不起作用。
CODE：
import cookielib
import urllib2
import mechanize
# Browser
br = mechanize.Browser()
# Enable cookie support for urllib2
cookiejar = cookielib.LWPCookieJar()
br.set_cookiejar( cookiejar )
# Broser options
br.set_handle_equiv( True )
br.set_handle_gzip( True )
br.set_handle_redirect( True )
br.set_handle_referer( True )
br.set_handle_robots( False )
br.set_handle_refresh( mechanize._http.HTTPRefreshProcessor(), max_time = 1 )
br.addheaders = [ ( 'User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1' ) ]
# authenticate
br.open('WEB')
br.select_form("loginForm")
br.form['userName'] = 'xxx'
br.form['password'] = 'xxx'
br.submit()
# Inside the webpage
nextPage = br.find_link(text_regex = "Configuración")
br.follow_link(nextPage)
nextPage = br.find_link(text_regex = "Importar Tickets")
br.follow_link(nextPage)
br.select_form("ImporterForm")
br.form['Field Separator'] = ['1'] #CSV
br.submit()
br.select_form("ImporterForm")
br.form.add_file(open("ticket_import_template.csv"), 'text/plain', "ticket_import_template.csv")
br.submit()
我解释了代码的最后一部分：当选择最后一个表单时，我必须更改上传到CSV的文件类型，然后submit()它（在HTML代码中onClick=submit()出现）。然后，当我再次选择它并执行print br.form时，它会告诉我已选中CSV单选按钮，这样该部分就可以了。
然后我使用br.form.add_file(open("ticket_import_template.csv"), 'text/plain', "ticket_import_template.csv")上传文件。当我print br.form时，我可以看到文件在那里：<FileControl(7.37.0.0.0.3.3.1.1.1.51=ticket_import_template.csv)>
我复制了网页的部分HTML，以防它有用：

<strong class="label">Añadir nuevas entidades<br></strong>
Specifies whether entities referred to by import records should be added if they do not yet exist in the database.
<br/>
<br/> For example, consider an import file having a Localización column, with one of its rows having <i>North Campus</i> for its Localización value. If <b>Add New Entities</b> is unchecked, and <i>North Campus</i> has not yet been entered into the Web Help Desk as a Localización, then the importer will give an error. If <b>Add New Entities</b> is checked, the importer will create a new Localización named <i>North Campus</i>.
<br/>
<br/> Some entities require multiple fields and therefore cannot be created based on a single attribute. For example, Clientes are referenced in import files by e-mail or username, but a new Cliente cannot be created based solely on an e-mail or username. If a Cliente with a matching username or e-mail does not exist, the importer will give an error even if <b>Add New Entities</b> is checked.
<br/>
<br/> <font color="red"><b>Note: </b> This setting does not prevent the importer from creating new records of the base type being imported. It refers only to entities of other types that are referred to by the base records. (E.g., the data file for an Recurso import can add new Recursos regardless of this setting.) </font>

我意识到Mechanize不支持JavaScript。试过requests，但这很难。
最后我决定使用Selenium。做了一些find_element_by_xpath("...")我得到了最终表格，并click()编辑了提交按钮。
