Back4app上传对象问题

Question

我正在尝试通过back4app为类sound创建一个对象

我有的问题是无法上传文件。

使用的代码：

import requests

headers = {
    "X-Parse-Application-Id": "hidden",
    "X-Parse-REST-API-Key": "hidden",
}


data = {
    "audio": {
        "__type": open("a.mp3", 'rb'),
        "name": "a.mp3"

    },
    "displayText": "test"
}


def main(url):
    with requests.Session() as req:
        req.headers.update(headers)
        r = req.post(url, data=data)
        print(r.text)


main("https://parseapi.back4app.com/classes/sounds")

输出：

{"code":111,"error":"schema mismatch for sounds.audio; expected File but got Array"}

您首先需要上传文件：

import json,httplib
connection = httplib.HTTPSConnection('parseapi.back4app.com', 443)
connection.connect()
connection.request('POST', '/files/a.mp3', open('a.mp3', 'rb').read(), {
       "X-Parse-Application-Id": "${APPLICATION_ID}",
       "X-Parse-REST-API-Key": "${REST_API_KEY}",
       "Content-Type": "audio/mpeg"
     })
result = json.loads(connection.getresponse().read())

然后创建对象：

connection.request('POST', '/classes/sounds', json.dumps({
       "displayText": "test",
       "audio": {
         "name": result["name"],
         "url:": result["url"],
         "__type": "File"
       }
     }), {
       "X-Parse-Application-Id": "${APPLICATION_ID}",
       "X-Parse-REST-API-Key": "${REST_API_KEY}",
       "Content-Type": "application/json"
     })
connection.getresponse().read()
