While testing my Google App Engine application, I search for links which include app engine keys. For example:
在测试我的谷歌应用程序引擎应用程序时，我搜索包含应用程序引擎键的链接。例如:
/story/ag5yZXBsaWUtdGVzdGluZ3IMCxIFU3RvcnkY-w0M/
What characters are allowed in these keys? I had been using the regex [a-zA-Z0-9], but it seems "-" is also allowed. What else?
这些键中允许使用什么字符?我一直在使用regex [a-zA-Z0-9]，但似乎“-”也是允许的。还有什么?
Is there a reference on this? I can't find it in the App engine docs.
有关于这个的参考吗?我在App engine文档中找不到。

Google App Engine keys are encoded using URL safe base 64 encoding (see The source code for the Key datastore type).

it's very probably all digits, upper- and lowercase letters, underscore and hyphen (try to base64.urlsafe_b64decode this string ;) )
它很可能是所有的数字，大写和小写字母，下划线和连字符(尝试使用base64)。urlsafe_b64decode这个字符串;)
