google.auth.exceptions.RefreshError

Question

我的问题是我无法将文件添加到我的Google云存储桶中

def upload():
    from flask import request
    """Process the uploaded file and upload it to Google Cloud Storage."""
    uploaded_file = request.files.get('file')

    if not uploaded_file:
        return 'No file uploaded.', 400

    # Create a Cloud Storage client.
    credentials = compute_engine.Credentials()
    gcs = storage.Client(credentials=credentials, project="ISL-Creative")
    # gcs = storage.Client()
    # Get the bucket that the file will be uploaded to.
    bucket = gcs.get_bucket('label_creative')
    # Create a new blob and upload the file's content.
    blob = bucket.blob(uploaded_file.filename)
    blob.upload_from_string(
        uploaded_file.read(),
        content_type=uploaded_file.content_type
    )

    # The public URL can be used to directly access the uploaded file via HTTP.
    return 'ok'

google.auth.exceptions.RefreshError：HTTPConnectionPool（host ='metadata.google.internal'，port = 80）：URL超过了最大重试次数：/ computeMetadata / v1 / instance / service-accounts / default /？recursive = true（由于NewConnectionError（'：导致无法建立新连接：[Errno 8]节点名或提供的服务名，或者未知'））

Answer 1

该错误表明您的进程无法找到metadata.google.internal。这可能是：

1. 您没有在Google Compute Engine上运行。 compute_engine.Credentials()仅在GCE上运行时适用。在其他系统上使用不同的凭据。 （实际上，在GCE和GAE上，您根本不需要指定凭据-自动使用默认凭据）

2. 您有一个DNS问题，解决了metadata.google.internal。确保metadata.google.internal解析为169.254.169.254。
