Get a JSON object in python

Question

Usually my webservice built with Bottle return JSON files, which works fine. But, I've an exception that need to call a local function.

Here is what I tried to do:

import json
def getData():
    return json.dumps({'data': someData })

def function():
    try:
        # Fail
    except:
        print getData()
        print type(getData())
        json.load(getData())

So it prints:

{"data": "myData"}
<type 'str'>
[...]
AttributeError: 'str' object has no attribute 'read'

So json.dumps gives me a string. How can I use it as JSON ?

Sorry, I rewrite it to make it simple. I've forgot the return. — Arthur

someData is already a dict() you just access someData ... at least it should be. If it's a string then you need to call json.load() on it — Cfreak

@Cfreak It seems to be a dict because of the { ... }, but it's actually a string. — Arthur

json.load loads JSON from a file object.

json.loads loads from a string. This is what you want.

I knew there was a simple answer. Thank you.

Technically it's a file-like object (has read() method), so this will work: json.load(StringIO('["streaming API"]'))

Use json.loads instead of json.load. As per the docs.
