如何使用drf-chunked-upload库将文件上传到服务器？

Question

我尝试了许多方法将文件上传到服务器，但总是得到响应{"detail"：“没有提交块文件”}。如何正确使用这个库？

我的一个尝试是：

import requests

url = 'http://127.0.0.1:8000/chunked_upload/'

in_file = open("testfile.txt", "rb")
data = in_file.read()
response = requests.put(
    url,
    headers={
        "Content-Range": f"bytes {0}-{9}/{10}"
    },
    data={"filename": "testfile"},
    files={'file': data},
)

Answer 1

打开一个文件，分块重复向服务器发出PUT请求。要完成上传，请使用文件的校验和发出POST请求。

示例

import hashlib
import os

import requests
from requests.auth import HTTPBasicAuth

auth = HTTPBasicAuth(username='username', password='password')

file = 'prova.txt'

size = os.path.getsize(file)

hash_md5 = hashlib.md5()

CHUNK_SIZE = 100

with open(file, 'rb') as f:
    url = 'http://localhost:8000/'
    offset = 0
    for chunk in iter(lambda: f.read(CHUNK_SIZE), b''):
        hash_md5.update(chunk)
        res = requests.put(
            url,
            data={'filename': 'my_new_file'},
            files={'file': chunk},
            headers={
                'Content-Range': f'bytes {offset}-{offset + len(chunk) -1}/{size}'
            },
            auth=auth
        )
        offset = int(res.json().get('offset'))
        url = res.json().get('url')
    finalize = requests.post(url, data={'md5': hash_md5.hexdigest()}, auth=auth)
    print(finalize.status_code)
    print(finalize.json())
