python - 将文本文件上传到站点以使用 MechanicalSoup 进行分析

Question

我正在尝试将文本文件发送到 TreeTagger Online对其进行分析并获取要下载的结果文件的链接。

import mechanicalsoup  
browser = mechanicalsoup.Browser()
homePage = browser.get("http://cental.fltr.ucl.ac.be/treetagger/")
formPart = homePage.soup.select("form[name=treetagger_form]")[0]
formPart.select("[name=file_to_tag]")[0]["name"]=open('test.txt', 'rb')
result = browser.post(formPart, homePage.url)

这给了我以下错误:

: (, UnicodeEncodeError('ascii', u'No connection adapters were found for \'\n\n\n\n\n Texte \xe0 \xe9tiqueter : \n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\'', 216, 217, 'ordinal not in range(128)'))

我应该如何在现场获取我的文件(使用 MechanicalSoup 或其他模块)？

尽管我没有设法让@Rolando Urquiza 的答案在我的机器上运行，但我还是能够根据他的建议完成任务。

import mechanicalsoup  
browser = mechanicalsoup.Browser()
homePage = browser.get("http://cental.fltr.ucl.ac.be/treetagger/")
formPart = homePage.soup.select("form[name=treetagger_form]")[0]
form=mechanicalsoup.Form(formPart)
form.set('file_to_tag', 'test.txt')
upload=browser.submit(form,url="http://cental.fltr.ucl.ac.be/treetagger/")

感谢@Rolando Urquiza

Answer 1

根据 MechanicalSoup 的文档，您可以在 mechanicalsoup.Form 实例上使用 set 函数上传文件，参见 here .例如，您可以这样使用它:

import mechanicalsoup  
browser = mechanicalsoup.StatefulBrowser()
browser.get("http://cental.fltr.ucl.ac.be/treetagger/")
form = browser.select_form()
form.set('file_to_tag', 'test.txt')
result = browser.submit_selected()
