Question

我有一些文件，我从Evernote API（通过getResource）收到并使用以下代码写入Google云端存储：

gcs_file = gcs.open(filename, 'w', content_type=res.mime,
                    retry_params=write_retry_params)

# Retrieve the binary data and write to GCS
resource_file = note_store.getResource(res.guid, True, False, False, False)
gcs_file.write(resource_file.data.body)

gcs_file.close()

对于某些类型的文档，它仍然有效。但是有些文件表明GCS会在日志中抛出这些文件：

Unable to fetch URL: https://storage.googleapis.com/evernoteresources/5db799f1-c03c-4056-812a-6d77bad55261/Sleep Away.mp3

和

Got exception while contacting GCS. Will retry in 0.11 seconds.

这些错误似乎没有任何模式。它发生在文档，声音，图片等等 - 这些文档类型中的一些有用，有些则不适用。这不是因为尺寸（因为一些小工作和一些大工作）。

有什么想法吗？

这里是完整的堆栈跟踪，但我不确定它会有所帮助。

Answer 1

谢谢Brian！问题是文件名中的空格。我只是使用urllib2.quote()来获取那些，它就像一个魅力。

Answer 2

这是gcs客户端代码中的错误。它应该正确处理文件名。它使用http请求到GCS的事实应该是“隐藏的”。这将很快修复。谢谢！

请注意，如果您自己引用文件名以解决此错误，则修复后文件名将被双引号。遗憾。
