上传文件和简历到 azure blob 存储 python

Question

下面是分块上传文件的代码：

azure_container = "dummy-container"


file_path = "test.txt"

chunk_size=4*1024*1024

blob_service_client = BlobServiceClient.from_connection_string(azure_connection_string)
blob_client = blob_service_client.get_blob_client(container=azure_container, blob="testingfile.txt")


test_main = []
with open(file_path, 'rb') as datax:

    #while True:
    chunk_data = datax.read(chunk_size)
    print(len(chunk_data))
    #chunk_data = [str(chunk_data, 'utf-8').split("\r")]

    # for q in chunk_data[0]:
    #     time.sleep(0.5)
    #     print(q.strip())
    #print(chunk_data)
    blob_client.upload_blob(chunk_data, overwrite=True)

如果在上传过程中发生某些事情，我想恢复上传，因为我正在使用数据块并记录数据块以从左侧继续，但是如何在不覆盖的情况下上传？ 换句话说，在停止后继续上传相同的文件。

对于这个“异步”和“等待”工作正常。 但如果有更好的解决方案，请发布。

async def uploadin_files(file_path):
    for files_to_upload in file_path:
        time.sleep(2)
        blob_client = blob_service_client.get_blob_client(container=azure_container, blob=files_to_upload)
        with open(files_to_upload, 'rb') as datax:
            chunk_data_original = datax.read()
            blob_client.upload_blob(chunk_data_original, overwrite=True)
            print(files_to_upload,"Done uploading")

await uploadin_files(file_path_main)

它甚至在断开连接后也能正常工作。网络有时会再次连接回来！
