python-3.x - 向服务器发送数据时如何正确上传图像

Question

我已经实现了一个用于注册组织的视图。给定以下有效负载，如何成功上传文件：

{
"admin":{
        "username":"[e-mail]",
        "first_name":"Cindy",
        "last_name":"Georgia",
        "password":"password",
        "email":"[e-mail]"
    },
"org":{
        "name":"ARIZONA LAW SOCIETY",
        "short_name":"ALS",
        "tag_line":"ALS",
        "email":"[e-mail]",
        "company_phone": "[phone]",
        "po_box": "200",
        "location":"NAKURU",
