小编Sim*_*mon的帖子

有了这段代码

import sense
import json

sense.api_key = '...'
node = sense.Node.retrieve('........')
feed = node.feeds.retrieve('presence')

events = feed.events.list(limit=1)

result = json.dumps(events,indent=1)
print result

我得到一个像这样的JSON-Feed:

{
 "links": {...}, 
 "objects": [
  {
   "profile": "GenStandard", 
   "feedUid": ".....", 
   "gatewayNodeUid": ".....", 
   "dateServer": "2015-02-28T09:57:22.337034", 
   "geometry": null, 
   "data": {
    "body": "Present", 
    "code": 200
   }, 
   "signal": "-62", 
   "dateEvent": "2015-02-28T09:57:22.000000", 
   "type": "presence", 
   "payload": "2", 
   "nodeUid": "....."
  }
 ], 
 "totalObjects": 875, 
 "object": "list"
}

如何检查'body'是否"存在"(或'代码'是'200')？我的脚本应该返回TRUE或FALSE

UPDATE

如果我按照答案中的建议添加此代码,它可以正常工作:

d=json.loads(result)
def checkJson(jsonContents):
    bodyFlag = True if "body" in jsonContents["objects"][0]["data"] and jsonContents["objects"][0]["data"]["body"] == "Present" …

我用modernizr加载jQuery,'complete'函数中的所有代码运行正常!但是,如果我试图从外部'Moderniz.load'调用一些js,那么firebug说:'$未定义'.

这有效:

<script>
Modernizr.load([
{
    load: [ '//ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js', '//ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js'],
    complete: function () {
      if ( !window.jQuery ) {
            Modernizr.load('/weblounge-sites/www/js/jquery-1.7.min.js', '/weblounge-sites/www/js/jqueryui-1.8.min.js');
      }
    }
},
{
    load: [ 'some additional scripts' ],
    complete: function() {
        $ = jQuery;
        $(document).ready(function(){
          some js
          });

        });
    }
},  
{
    test: Modernizr.boxshadow,
    nope: 'polyfills/PIE.js',
}
]);
</script>

但是后来视图行的调用失败了:

<script>
$(document).ready(function(){
    $('#hauptsponsoren').cycle({
        fx: 'fade', 
        speed: 4000,
        timeout: 10000
    });                 
});
</script>
