关于#python#的问题：python分段上传

Question

我设置的明明是1M，为什么每次上传给我上传了2M。

import math
import os

import requests


def upload_slice_file(url, file_path):
    chunk_size = 1048576  # 1M分段
    # filename = file_path.split("\\") # [0][0:-4] 分割去.zip
    total_size = os.path.getsize(file_path)  # 计算总字节流
    current_chunk = 1
    total_chunk = math.ceil(total_size / chunk_size)
    # while current_chunk <= total_chunk:
    for i in range(total_chunk):
        start = (current_chunk - 1) * chunk_size
        print('sta',start)
        end = min(total_size, start + chunk_size)
        print('end',end)
        with open(file_path, 'rb') as f:
            f.seek(start)
            file_chunk_data = f.read(end - start)
            print(len(file_chunk_data))
            token = 'C8xX4aT1wG1x'
            pid = 3021
            veakey = 'G9tZ8jZ8i'
            datafd = 'filename={}&token={}&pid={}&veakey={}&total_blob_num={}&blob_num={}'.format(veakey, token, pid,
                                                                                                  veakey, total_chunk,
                                                                                                  current_chunk)

        data = {"file": (file_chunk_data, 'application/octet-stream')}

        res = requests.post(url + datafd, data=data)
        print(res.json(), res.url)
        # with requests.post(url+datafd,data=data) as response:
        #     assert response.status_code == 200

        current_chunk = current_chunk + 1

困惑已久的我还是找到问题了。
不应该用，data = {"filename": (file_chunk_data, 'application/octet-stream')}来传。
直接data = file_chunk_data就可以了。
