在 Cloud Storage 上上传 Blob 时出现 400 错误

Question

我在 Cloud Function 中创建了一个 csv 文件。现在，我需要将它上传到 Cloud Storage。我将它存储在 /tmp 文件中。从那里，我必须将其上传到 Cloud Storage。

使用的代码 -

def upload_blob(bucket_name, source_file_name, destination_blob_name):
    """Uploads a file to the bucket."""
    storage_client = storage.Client()
    bucket = storage_client.get_bucket(bucket_name)
    blob = bucket.blob(destination_blob_name)
    blob.upload_from_file(source_file_name)
    print('File {} uploaded to {}.'.format(source_file_name,destination_blob_name))

final_df.to_csv('/tmp/'+file_name)
with open('/tmp/'+file_name, 'r') as file_obj:
    upload_blob('test-bucket',file_obj,file_name)

但是，我面临以下错误 -

BadRequest: 400 PUT https://www.googleapis.com/upload/storage/v1/b/test-bucket/o?uploadType=resumable&upload_id=ABC: ('Request failed with status code', 400, 'Expected one of', <HTTPStatus.OK: 200>, 308)

文件存储在 /tmp 文件夹中。从那里，它没有被上传。究竟是什么错误？

400 error Bad request（不是 404）有很多可能的原因。也许您应该指定完整路径并且您没有打开文件并将其传递给 source_file_name。这是我尝试成功将对象（使用 mp3 文件尝试）上传到 GCS 的内容

from google.cloud import storage

def upload_blob(bucket_name, source_file_name, destination_blob_name):
    """Uploads a file to the bucket."""
    storage_client = storage.Client()
    bucket = storage_client.get_bucket(bucket_name)
    blob = bucket.blob(destination_blob_name)

    blob.upload_from_filename(source_file_name)

    print('File {} uploaded to {}.'.format(
        source_file_name,
        destination_blob_name))


if __name__ == '__main__':
    upload_blob ("[bucketname]", "/home/[username]/[filename]", "[filename]")
