将JSON转换为Python对象:如何处理DateTime转换? [英] Convert JSON to Python object: how to handle DateTime conversion?

问题描述

我有一个C#控制台应用程序，它将POCO类序列化为JSON字符串；我使用JSON.Net进行序列化.

I have a C# console app that serializes a POCO class to a JSON string; I use JSON.Net for serialization.

此应用程序中的JSON被转储到文件中，并由Python 2.7脚本读取.

The JSON from this app is dumped to a file, and read in by a Python 2.7 script.

这是问题所在. JSON序列化将类中的所有datetime属性都转换为以下格式:

Here's the problem. The JSON serialization takes all the datetime properties on my class and converts them to this format:

/Date(1322856016353-0500)/

当我使用json.parse时；我收到了与Python原始班级相当的成果；除了所有的DateTime属性，现在都是包含"/Date(1322856016353-0500)/"而不是Python datetime字段的字符串.

When I use json.parse; I receive the equivalent of my original class in Python; except all of the DateTime properties are now strings containing "/Date(1322856016353-0500)/" instead of Python datetime fields.

似乎我需要手动从字符串中解析时间并手动创建datetime obj.在我这样做之前；有一个更好的方法吗?也许我可以将DateTime属性以另一种格式序列化为JSON?还是使用其他Python JSON解析器?

It looks like I'm going to need to manually parse the time out of the string and create a datetime obj manually. Before I do that; is there a better way to do this? Perhaps I could serialize the DateTime properties to JSON in another format? Or use a different Python JSON parser?

非常感谢任何建设性的投入.

Any constructive input is greatly appreciated.

谢谢， 弗兰克

推荐答案

您可以指定所需的格式.尝试这样的事情:

You can specify the format you want. Try something like this:

DATETIME_FORMAT = '%Y-%m-%d %H:%M:%S'

序列化之前: time = datetime.strftime(time, DATETIME_FORMAT)

反序列化后: time = datetime.strptime(time, DATETIME_FORMAT)
