在python中为应用程序引擎生成json [英] Generating json in python for app engine
问题描述
我对Python有点新，我想知道在循环中生成json的最好方法是什么。我可以在循环中混合一堆字符串，但我相信有更好的方法。这里有一些更具体的细节。我在python中使用app引擎创建一个返回json作为响应的服务。
I am somewhat new to python and I am wondering what the best way is to generate json in a loop. I could just mash a bunch of strings together in the loop, but I'm sure there is a better way. Here's some more specifics. I am using app engine in python to create a service that returns json as a response.
例如，假设有人从服务请求了一列用户记录。服务查询记录后，它需要为找到的每个记录返回json。可能是这样的：
So as an example, let's say someone requests a list of user records from the service. After the service queries for the records, it needs to return json for each record it found. Maybe something like this:
{records:
{record: { name:bob, email:blah@blah.com, age:25 } },
{record: { name:steve, email:blah@blahblah.com, age:30 } },
{record: { name:jimmy, email:blah@b.com, age:31 } },
}
原谅我格式不正确的json。感谢您的帮助。
Excuse my poorly formatted json. Thanks for your help.
推荐答案
我的问题是如何添加到
字典动态？因此，在我的记录列表中记录
记录，并在字典中添加
记录。
My question is how do I add to the dictionary dynamically? So foreach record in my list of records, add a record to the dictionary.
您可能会希望创建一个字典列表。
You may be looking to create a list of dictionaries.
records = []
record1 = {"name":"Bob", "email":"bob@email.com"}
records.append(record1)
record2 = {"name":"Bob2", "email":"bob2@email.com"}
records.append(record2)
然后在应用引擎中，使用上面的代码导出记录作为json。
Then in app engine, use the code above to export records as json.
