将不同内容类型的MHT文件提取到多个MHT文件中

Question

我正在编写一个mht脚本来解析mht文件并从父级提取部分消息并将其写入单独的mht文件

我编写了以下函数，该函数在file_location打开一个mht文件并搜索特定的content_id并将其写入新的mht文件

def extract_content(self, file_location, content_id,extension):
    first_part = file_location.split(extension)[0]
    #checking if file exists
    new_file = first_part + "-" + content_id.split('.')[0] + extension

    while os.path.exists(new_file):
        os.remove(new_file)

    with open(file_location, 'rb') as mime_file, open(new_file, 'w') as output:
        ***#Extracting the message from the mht file***
        message = message_from_file(mime_file)
        t = mimetypes.guess_type(file_location)[0]

        #Walking through the message
        for i, part in enumerate(message.walk()):

            #Check the content_id if the one we are looking for
            if part['Content-ID'] == '<' + content_id + '>':
                ***witing the contents***
                output.write(part.as_string(unixfrom=False))

显然，在application / pdf和application / octet-stream的情况下，我无法在IE中打开输出部分。

我如何将这些Content-Type（如application / pdf和application / octet-stream）写入mht文件，以便能够在IE中查看图像或pdf？

谢谢

尝试这个：

...
if m['Content-type'].startswith('text/'):
                    m["Content-Transfer-Encoding"] = "quoted-printable"

                else:
                    m["Content-Transfer-Encoding"] = "base64"

                m.set_payload(part.get_payload())                        
                ****Writing to output****
                info = part.as_string(unixfrom=False)
                info = info.replace('application/octet-stream', 'text/plain')
                output.write(info)
...

告诉我是否可行。
