simplejson

问题 What is the most efficient way of serializing a numpy array using simplejson? 回答1: I'd use simplejson.dumps(somearray.tolist()) as the most convenient approach (if I was still using simplejson at all, which implies being stuck with Python 2.5 or earlier; 2.6 and later have a standard library module json which works the same way, so of course I'd use that if the Python release in use supported it;-). In a quest for greater efficiency, you could subclass json.JSONEncoder (in json ; I don't know

问题 currently I have the following which parses a json api.. import simplejson import urllib2 f = urllib2.urlopen('http://fanart.tv/webservice/series/f5b8e776c35e7536eac132802b03281f/80349/json/tvthumb/') data = simplejson.load(f) imagetypes = ['clearlogo', 'clearart', 'tvthumb', 'seasonthumb', 'characterart'] image_list = [] # split "name" and "data" for title, value in data.iteritems(): # run through specified types for art in imagetypes: # if type has been found if value.has_key(art): # Run

问题 This question already has answers here : Items in JSON object are out of order using “json.dumps”? (6 answers) Closed 6 years ago . When working with simplejson in Django, I sometimes need to send the information strictly in order. values = {"entry1":"value1","entry2":"value2","entry3":"value3"} return HttpResponse(simplejson.dumps(values),content_type="application/json") That's what it returns {"entry2": "value2", "entry3": "value3", "entry1": "value1"} But I want it to returns this instead:

问题 The problem was with print statements. In app engine avoid print, use logger. I have a python dict containing unicode strings. I need to send the dict to the javascript code to do page refresh. I am doing something like this. map=getMap() return Response(simplejson.dumps(map)) In the javascript code how ever I get following response, True,0,1,2........... {map data}. I was expecting only {map data} not True,0,1,2... as prefix. Do you know why is this happening. It only happens when there is

问题 I'm trying to use Simple JSON to convert this string to JSON : "{\"objects\":[{\"id\":1,\"title\":\"Book\",\"position_x\":0,\"position_y\":0,\"position_z\":0,\"rotation_x\":0,\"rotation_y\":0,\"rotation_z\":0,\"created\":\"2016-09-21T14:22:22.817Z\"},{\"id\":2,\"title\":\"Apple\",\"position_x\":0,\"position_y\":0,\"position_z\":0,\"rotation_x\":0,\"rotation_y\":0,\"rotation_z\":0,\"created\":\"2016-09-21T14:22:52.368Z\"}]}" Unfortunately, it appears that Visual Studio doesn't have Interactive

问题 I'm trying to build a realtime chat app in Django(1.7.1). It seems that I needed to install Redis and ishout.js. So I installed them by following the instructions. After making the project in Django, I put 'drealtime' under the INSTALLED_APPS, and put: 'drealtime.middleware.iShoutCookieMiddleware' right above : 'django.contrib.sessions.middleware.SessionMiddleware' under the MIDDLEWARE_CLASSES as it was saying. And I put the command like python manage.py startapp example but still I have this

问题 I'm trying to encode a Python array into json using simplejson.dumps: In [30]: s1 = ['test', '<script>'] In [31]: simplejson.dumps(s1) Out[31]: '["test", "<script>"]' Works fine. But I want to escape the strings first (using escapejs from Django) before calling simplejson.dumps: In [35]: s_esc Out[35]: [u'test', u'\\u003Cscript\\u003E'] In [36]: print simplejson.dumps(s_esc) ["test", "\\u003Cscript\\u003E"] My problem is: I want the escaped string to be: ["test", "\u003Cscript\u003E"] instead
