解析python中的json字段

Question

是否有一个很好的教程解析python中的json属性？我希望能够解析"ok"字段的真实值.以及名为"client_ind_1"的索引.我不明白这个主题的python文档报道.如果有人可以向我解释或指出更好的资源,那就太棒了.

我的json字符串如下所示:

{
    "ok": true,
    "_shards": {
        "total": 2,
        "successful": 1,
        "failed": 0
    },
    "indices": {
        "client_ind_2": {
            "index": {
                "primary_size": "2.5mb",
                "primary_size_in_bytes": 2710326,
                "size": "2.5mb",
                "size_in_bytes": 2710326
            }
        }
    }
}

先感谢您.

import json

a =  """{
    "ok": true,
    "_shards": {
        "total": 2,
        "successful": 1,
        "failed": 0
    },
    "indices": {
        "client_ind_2": {
            "index": {
                "primary_size": "2.5mb",
                "primary_size_in_bytes": 2710326,
                "size": "2.5mb",
                "size_in_bytes": 2710326
            }
        }
    }
}"""

b = json.loads(a)

print(b['ok'])
print(b['indices']['client_ind_2']['index'])

这将把json作为python字典,并打印你想要的'ok'和索引值:

True
{u'primary_size': u'2.5mb', u'primary_size_in_bytes': 2710326, u'size_in_bytes': 2710326, u'size': u'2.5mb'}
