--12345--

我在这个 w3.org 页面上发现可以将 multipart/mixed 头封装在 multipart/form-data 中，只需在 multipart/mixed 中选择另一个边界字符串并使用它来封装数据。最后，您必须“关闭” FILO 中使用的所有边界以关闭 POST 请求（例如：

Content-Type: multipart/mixed; boundary=abcde
--abcde
Content-Disposition: file; file="picture.jpg"

--abcde
Content-Disposition: file; file="test.py"
