Parse decodeURIComponent JSON string with Python

我有一个"深" JSON字符串，我需要在URL中作为GET变量传递。它看起来像这样:

{
  "meta": {
    "prune": true,
    "returnFields": ["gf", "gh", "gh", "rt"],
    "orient": "split"
  },
  "indicators": [{
    "type": "beta",
    "computeOn": "gf",
    "parameters": {
      "timeperiod": 5,
      "nbdevup": 2,
      "nbdevdn": 2,
      "matype": 0
    }
  }, {
    "type": "alpha",
    "computeOn": "gf",
    "parameters": {
      "timeperiod": 30
    }
  }]
};

使用jQuery.param编码时，结果如下:

var recursiveEncoded = jQuery.param(body);
console.log(recursiveEncoded);
meta%5Bprune%5D=true&meta%5BreturnFields%5D%5B%5D=gf&meta%5BreturnFields%5D%5B%5D=gh&meta%5BreturnFields%5D%5B%5D=gh&meta%5BreturnFields%5D%5B%5D=rt&meta%5Borient%5D=split&indicators%5B0%5D%5Btype%5D=beta&indicators%5B0%5D%5BcomputeOn%5D=gf&indicators%5B0%5D%5Bparameters%5D%5Btimeperiod%5D=5&indicators%5B0%5D%5Bparameters%5D%5Bnbdevup%5D=2&indicators%5B0%5D%5Bparameters%5D%5Bnbdevdn%5D=2&indicators%5B0%5D%5Bparameters%5D%5Bmatype%5D=0&indicators%5B1%5D%5Btype%5D=alpha&indicators%5B1%5D%5BcomputeOn%5D=gf&indicators%5B1%5D%5Bparameters%5D%5Btimeperiod%5D=30

解码为:

var recursiveDecoded = decodeURIComponent( jQuery.param(body) );
console.log(recursiveDecoded);
meta[prune]=true&meta[returnFields][]=gf&meta[returnFields][]=gh&meta[returnFields][]=gh&meta[returnFields][]=rt&meta[orient]=split&indicators[0][type]=beta&indicators[0][computeOn]=gf&indicators[0][parameters][timeperiod]=5&indicators[0][parameters][nbdevup]=2&indicators[0][parameters][nbdevdn]=2&indicators[0][parameters][matype]=0&indicators[1][type]=alpha&indicators[1][computeOn]=gf&indicators[1][parameters][timeperiod]=30

如果仅在服务器上使用序列化字符串结果，则将该字符串作为键值对中的键:

"query": {
    "{'"meta'":{'"prune'":true,'"returnFields'":['"gf'",'"gh'",'"gh'",'"rt'"],'"orient'":'"split'"},'"indicators'":[{'"type'":'"beta'",'"computeOn'":'"gf'",'"parameters'":{'"timeperiod'":5,'"nbdevup'":2,'"nbdevdn'":2,'"matype'":0}},{'"type'":'"alpha'",'"computeOn'":'"gf'",'"parameters'":{'"timeperiod'":30}}]}": ""
  },

我的后端处理是用Python完成的。存在哪些模块将上述结果转换为类似于原始对象的dict ?

既然我们在评论中讨论了这个问题，我就把答案贴在这里，供后人参考。

在JavaScript端使用JSON.stringify来序列化数据结构，在Python端使用json.loads来反序列化数据结构。将序列化的结构作为查询字符串参数传递(在您的示例中为"query")，然后在Python中从该查询字符串参数中读取值。万岁!
