推荐答案

我浪费了很多时间使用curl和httpie。
最好，最简单的方法是使用 python请求。

I wasted lot of time using curl and httpie. The best and easy way is use python requests.

我发现这种使用Django Rest Framework命令行上传图像的方法。

I found this way to command line upload image using Django Rest Framework.

import requests
files = {'thumb': open('D:/thumb.jpg', 'rb'), 'preview': open('D:/preview.jpg', 'rb')}
r = requests.put('/path/to/your/django/rest/api', data={'key': value, 'key2': 'value2'}, files=files)
print r.status_code

如果您获得201，则表示您完成了。

If you get 201, means you done.
