Google Cloud Storage 生成上传/下载 URL 失败，blobname 中包含 unicode 个字符

Question

我最近一直在测试在 GCS 上上传和下载，只要 blobname 或“路径”都是英文字母，包括空格和特殊字符，我就能够毫无问题地生成上传和下载 URL。 但是，一旦我在文件名（blobname）中使用 unicode 个字符，它就会因KeyError而失败

文档提到支持 unicode：

Blob 的名称。 这对应object在桶中的唯一路径。 如果是字节，将被转换为 unicode object。Blob / object 名称可以包含任何有效的 unicode 字符序列，UTF-8 编码时长度为 1-1024 字节。

代码是几行：

generate_download_signed_url_v4("storage_files", "202209/جراج.png")

def generate_download_signed_url_v4(bucket_name, blob_name):
    storage_client = storage.Client.from_service_account_json('s_account.json')
    bucket = storage_client.bucket(bucket_name)
    blob = bucket.blob(blob_name)
    
    url = blob.generate_signed_url(
        expiration=datetime.timedelta(minutes=10), # This URL is valid for 10 minutes
        method="GET", # Allow GET requests using this URL.
    )
    
    print "Generated GET signed URL:", url
    return url

错误指的是 keyerror 以及 unicode 文件名部分 (blobname) 中第一个字符的 unicode 值

值得一提的是，这是在本地开发服务器 v.340 上

此问题已于 2018 年修复。查看中的行号和代码

 File "/Users/k/Documents/app30/gae/users_app/lib/google/cloud/storage/blob.py", line 338, in generate_signed_url
    quoted_name=quote(self.name))

确认正在使用该修复之前的版本（它们与此提交更改的版本相匹配）。 升级到1.11.0 之后的库版本。
