将数据从jquery-json传递到python

Question

我正在使用Python的app引擎项目，将数据从html页面（使用jQuery）发送到Python。

我正在使用这个jQuery插件将HTML表序列化为javascript对象：https://github.com/lightswitch05/table-to-json

function addFood() {
    var table = $('#planTable').tableToJSON();
    var info = {
        "user": "{{user}}",
        "plan": JSON.stringify(table)
    };
    $.ajax({
        type: "POST",
        url: "/addplan",
        dataType: "json",
        data: JSON.stringify(info)
    })
    .done(function(msg) {
        alert(msg.text);
     });
}

在Python中我有这个代码：

class AddPlanToDB(webapp2.RequestHandler):
    def post(self):
        info = json.loads(self.request.body) #retrive data from jQuery
        print info
        user = info['user']
        template_values = {
            'text': 'All done!'
        }
        self.response.out.write(json.dumps(template_values))

打印信息给我输出结果：

{u'plan': u'[{"Food":"Cheese, fontina","Grams":"100g","Pro":"25.6","Carbo":"1.6","Fat":"31.1","":""},{"Food":"Butter, salted","Grams":"50g","Pro":"0.4","Carbo":"0.0","Fat":"40.6","":""},{"Food":"Corn bran, crude","Grams":"200g","Pro":"16.7","Carbo":"171.3","Fat":"1.8","":""},{"Food":"","Grams":"Total:","Pro":"42.7","Carbo":"172.9","Fat":"73.5"}]', u'user': u'test@example.com'}

信息[＆＃​​39;用户＆＃39;] 会返回有关用户的正确信息。 但我无法检索有关

的数据

有谁能告诉我如何用Python获取这些数据？

提前致谢并抱歉我的小英语。

Answer 1

要获得有关饮食计划的信息，请执行以下操作

for item in json.loads(info['plan']):
    print item['Food']
    print item['Grams']
    print item['Pro']
    #etc

这是一个复制和粘贴示例

import json
data = {u'plan': u'[{"Food":"Cheese, fontina","Grams":"100g","Pro":"25.6","Carbo":"1.6","Fat":"31.1","":""},{"Food":"Butter, salted","Grams":"50g","Pro":"0.4","Carbo":"0.0","Fat":"40.6","":""},{"Food":"Corn bran, crude","Grams":"200g","Pro":"16.7","Carbo":"171.3","Fat":"1.8","":""},{"Food":"","Grams":"Total:","Pro":"42.7","Carbo":"172.9","Fat":"73.5"}]', u'user': u'test@example.com'}
for item in json.loads(data['plan']):
    print item['Food']
