Question

机械化框架非常适合自动化前几个网页。问题在于它需要以表格形式上传文件。

以下是错误之前的代码部分：

br.select_form(name="form.uploadXMLDataWizardForm")
xmlFile = codecs.open("MyFile.xml", "rt", "utf8")
br.form.add_file(file_object=xmlFile, content_type="text/xml", filename="MyFile.xml", name="dataFile")
br.submit(name="$action:next")

在运行时会导致以下错误：

    br.submit(name="$action:next")
  File "build/bdist.macosx-10.6-universal/egg/mechanize/_mechanize.py", line 541, in submit
  File "build/bdist.macosx-10.6-universal/egg/mechanize/_mechanize.py", line 530, in click

UnicodeEncodeError: 'ascii' codec can't encode characters in position 650-651: ordinal not in range(128)

知道如何让机械化处理上传UTF-8文件吗？

Answer 1

Mechanize似乎期望文件数据是原始字节，而不是Unicode数据。尝试使用通常的open()函数打开文件：

...
xmlFile = open("MyFile.xml", "rt")
...

Python Mechanize：上传UTF-8文件时的UnicodeEncodeError。 'ascii'编解码器
