我在 Django 视图中将日期时间转换为 ISO 8601 以推送到 Facebook 页面事件。我已经尝试过datetime.strptime，但遵循了我选择的最佳建议：

    eventdate = event.date
    print eventdate
    date_iso = dateutil.parser.parse(eventdate)

eventdate 在我打印时在控制台中看起来像这样，2013-06-18 02:50:00但在我得到之前它没有得到任何进一步：

这可能是什么？谢谢

我可以像这样重现错误消息：

In [58]: import datetime as DT

In [59]: eventdate = DT.datetime(2013, 6, 18, 2, 50)
In [60]: print(eventdate)
2013-06-18 02:50:00

In [61]: import dateutil.parser as parser
In [62]: parser.parse(eventdate)
AttributeError: 'datetime.datetime' object has no attribute 'read'

因此，在此基础上，它似乎eventdate可能已经是一个datetime.datetime对象。如果是这样，则无需致电

date_iso = dateutil.parser.parse(eventdate)

要将其转换为stringISO8601 格式，请使用

In [66]: eventdate.isoformat()
Out[66]: '2013-06-18T02:50:00'

错误很明显：您datetime实际上parse需要一个字符串时传入了一个对象。
