在Python中使用aiohttp上傳Google驅動器檔案

2022-06-09 00:17:53 .NET開發

我正在嘗試制作一個將檔案上傳到我的谷歌驅動器的功能。

下面的代碼上傳一個帶有請求的檔案。

import requests
import json

with open('storage.json', 'r') as file:
    token = json.load(file)
    token = token["access_token"]

url = "https://www.googleapis.com/upload/drive/v3/files"
file_metadata = {"name": "test.jpg",
                 "parents": [],
                 }
data = {
    "MetaData": (
        "metadata",
        json.dumps(file_metadata),
        "application/json; charset=UTF-8",
    ),
    "Media": open("test2.jpg", "rb"),
}

headers = {"Authorization": "Bearer {}".format(token)}
params = {"uploadType": "multipart"}

res = requests.post(url, files=data, params=params, headers=headers)
print(res.text)

現在，我想用 aiohttp 做一個異步函式。但是，我不知道該怎么做。下面是我當前的代碼，但它給出了 aiohttp.payload.LookupError。

async def upload_file(session, file_path, folder_id):
    '''
    * uploads a single file to the designated folder
    * args:
    - session: aiohttp session
    - file_path : absolute path of a file (e.g.) C:\Git\GoogleDriveAPI\test2.jpg
    - folder_id: folder id of the designated folder in google drive (e.g.) '1Q6gaU4kHaLRN5psS4S_2Yx_*******'
    '''
    file_name = file_path.split(os.path.sep)[-1]
    url = "https://www.googleapis.com/upload/drive/v3/files"
    file_metadata = {"name": file_name,
                     "parents": [folder_id],
                     }
    data = {
        "MetaData": (
            "metadata",
            json.dumps(file_metadata),
            "application/json; charset=UTF-8",
        ),
        "Media": open(file_path, "rb"),
    }
    global token
    headers = {"Authorization": "Bearer {}".format(token)}
    params = {"uploadType": "multipart"}
    async with session.post(url, data=data, params=params, headers=headers) as resp:
        print(resp.text)

這是我的完整代碼，以防您需要進行實驗。

uj5u.com熱心網友回復：

當我看到您的腳本時，我認為為了multipart/form-data使用您的腳本進行請求，需要創建請求正文。我認為這可能是您的問題的原因。當這反映在您的腳本中時，它變為如下。

從：

data = {
    "MetaData": (
        "metadata",
        json.dumps(file_metadata),
        "application/json; charset=UTF-8",
    ),
    "Media": open(file_path, "rb"),
}
global token
headers = {"Authorization": "Bearer {}".format(token)}
params = {"uploadType": "multipart"}
async with session.post(url, data=data, params=params, headers=headers) as resp:
    print(resp.text)

至：

data = aiohttp.FormData()
data.add_field(
    "metadata",
    json.dumps(file_metadata),
    content_type="application/json; charset=UTF-8",
)
data.add_field("file", open(file_path, "rb"))
global token
headers = {"Authorization": "Bearer {}".format(token)}
params = {"uploadType": "multipart"}
async with session.post(url, data=data, params=params, headers=headers) as resp:
    r = await resp.json()
    print(r)

測驗：

運行此修改后的腳本時，將獲得以下結果。

{'kind': 'drive#file', 'id': '###', 'name': '###', 'mimeType': '###'}
,
,
,

筆記：

  • 此修改后的腳本假設您的訪問令牌可用于將檔案上傳到 Google Drive。請注意這一點。
