如何在Django中打开原始文件进行解析？

Question

我需要在Django应用程序中浏览并打开.msg或.eml文件。我使用了forms和request.files，但是流提供了八位字节格式的数据。如何获取原始文件对象并将其作为普通文件打开以便解析它？

我有代码要分享。

<form action="{% url "upload_file_eml" %}" method="post" enctype="multipart/form-data">
     {% csrf_token %}
     <p>{{ form.non_field_errors }}</p>
     <p>{{ form.docfile.label_tag }} {{ form.docfile.help_text }}</p>
     <p>
         {{ form.docfile.errors }}
         {{ form.docfile }}
     </p>
     <p><input class="btn btn-primary btn-large" type="submit" value="Start Single Email Test"/></p>
</form>

documents = handle_uploaded_eml_file(request.FILES)

def handle_uploaded_eml_file(fileslist1):
    if(len(fileslist1['docfile']) == 0):
        return "No Files"
    else:
        filename1 = fileslist1['docfile'].name
        if(checking_for_extension for emails with .msg or eml):
            emlfile = fileslist1['docfile'].file
            msg2 = email.message_from_file(emlfile)
           //msg2 is in octet format it doesn't parse because file being .msg
           //what i kind want to do
           //emlfile = open(fileslist1['docfile'].file)
           //msg2 = emlfile.read()
           print("email subject:" + msg2["Subject"])
           return "Upload Success"
        else:
            return "Unsupported Format"
