无法将图片上传到Ghost CMS

Question

有人知道要使用python将图片上传到Ghost CMS吗？

url = "https://analisa.ifxid.trade/ghost/api/v3/admin/images/upload/"
headers = {'Authorization': 'Ghost {}'.format(token.decode()),'Content-Type': 'form-data;'}
files = {'file':('ifxb.png', open('ifxb.png', 'rb'))}
r = requests.post(url, headers=headers, files=files)
print(r.text)

结束
