python - 非空 gcs 存储桶返回 "can only concatenate str (not "字节") 到 str"

Question

我对 Google 云存储非常陌生。我正在使用教程https://cloud.google.com/storage/docs/boto-plugin使用 boto 创建一个到 google 云存储的存储桶。请查找下面的代码:

    import boto
    import gcs_oauth2_boto_plugin
    import time

    GOOGLE_STORAGE = 'gs'
    LOCAL_FILE = 'file'

    CLIENT_ID = "hnsdndsjsksoasjmoadsj"
    CLIENT_SECRET = "jdijeroerierper-er0erjfdkdf"

    gcs_oauth2_boto_plugin.SetFallbackClientIdAndSecret(CLIENT_ID, CLIENT_SECRET)

    now = time.time()

    # Your project ID can be found at https://console.cloud.google.com/
    # If there is no domain for your project, then project_id = 'YOUR_PROJECT'
    project_id = 'my-project-4749485'


    now = time.time()
    CATS_BUCKET = 'cats-%d' % now
    DOGS_BUCKET = 'dogs-%d' % now

    for name in (CATS_BUCKET, DOGS_BUCKET):
      uri = boto.storage_uri(name, GOOGLE_STORAGE)
      try:
        header_values = {"x-goog-project-id": project_id}
        uri.create_bucket(headers=header_values)

        print('Successfully created bucket "%s"' % name)
      except boto.exception.StorageCreateError as e:
        print('Failed to create bucket:', e)

当我运行它时，我得到:

/Users/dilipyadav/githome/elrond/venv/bin/python /Users/dilipyadav/githome/elrond/elrond/deploy3.py -t test -v 0.0.1
Traceback (most recent call last):

  File "/Users/dilipyadav/githome/elrond/venv/lib/python3.7/site-packages/boto/s3/connection.py", line 94, in build_auth_path
    path = '/' + bucket
TypeError: can only concatenate str (not "bytes") to str

Process finished with exit code 1

我在这里发现了类似的问题 - Can't collectstatic to s3 via Heroku using boto - s3 bucket returns a NoneType ，但没有帮助。

注意:CLIENT_ID、CLIENT_SECRET 和 project_id 替换为随机字符。

编辑:

    def build_auth_path(self, bucket, key=''):
        key = boto.utils.get_utf8_value(key)
        path = ''
        if bucket != '':
            path = '/' + bucket
        return path + '/%s' % urllib.parse.quote(key)

上面是来自connection.py的代码片段，我的代码失败了。在调试时，我得到的存储桶名称为“cats-1567682436”，这是一个字节值。我猜想当使用字符串“/”和字节桶创建路径时会失败。所以串联失败。

更改此行:

path = '/' + bucket

对此:

path = '/' + bucket.decode('utf-8')

但是，我会更改调用 build_auth_path() 的代码，并将存储桶 bytearray 首先转换为 string，然后调用 build_auth_path()。
