Python 实现 OSS 文件上传追加断点续传的示例代码，带有进度条

import os
import math
import oss2
from tqdm import tqdm

# 配置OSS Bucket信息
auth = oss2.Auth('', '')
bucket_name = ''
object_name = ''  # 上传后的对象名称
file_path = ''  # 本地待上传文件路径

# 初始化OSS客户端
bucket = oss2.Bucket(auth, 'http://oss-cn-beijing.aliyuncs.com', bucket_name)

# 获取已上传的分片信息
upload_id = None
parts = []
if os.path.exists(object_name + '.part'):
    with open(object_name + '.part', 'r') as f:
        upload_id = f.readline().strip()
        for line in f.readlines():
            if line.strip() == '':
                continue
            part_number, part_etag = line.strip().split('\t')
            parts.append(oss2.models.PartInfo(int(part_number), part_etag))

# 如果不存在上传记录，则创建新的分片上传任务
if upload_id is None:
    upload_id = bucket.init_multipart_upload(object_name).upload_id

# 分片上传文件
part_size = 50 * 1024 * 1024  # 每个分片的大小，这里设置为50MB
with open(file_path, 'rb') as f:
    index = len(parts) + 1
    file_size = os.path.getsize(file_path)
    part_count = int(math.ceil(file_size / part_size))
    with tqdm(total=file_size, unit='B', unit_scale=True, unit_divisor=1024) as pbar:
        while True:
            data = f.read(part_size)
            if not data:
                break
            part = bucket.upload_part(
                object_name,
                upload_id,
                index,
                data
            )
            parts.append(oss2.models.PartInfo(index, part.etag))
            uploaded_size = index * part_size
            if uploaded_size > file_size:
                uploaded_size = file_size
            pbar.update(uploaded_size - pbar.n)
            index += 1

# 将已上传的分片信息保存到本地
with open(object_name + '.part', 'w') as f:
    f.write(upload_id + '\n')
    for part in parts:
        f.write('{}\t{}\n'.format(part.part_number, part.etag))

# 完成分片上传
result = bucket.complete_multipart_upload(
    object_name,
    upload_id,
    parts
)

print('Upload successfully!')
