parsing json fields in python
提问by Horse Voice
Is there a good tutorial on parsing json attributes in python? I would like to be able to parse the true value for "ok" field. As well as the index named "client_ind_1". I don't understand the python document coverage on this topic. If someone could explain or point me to a better resource, it would be awesome.
有没有关于在 python 中解析 json 属性的好教程？我希望能够解析“ok”字段的真实值。以及名为“client_ind_1”的索引。我不了解有关此主题的 python 文档覆盖范围。如果有人可以向我解释或指出更好的资源，那就太棒了。
My json string looks like the below:
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
}
}
}
}
Thank you in advance.
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'])
This will take json as python dictionary and will print 'ok' and index value you want:
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'}

import json
dct = json.loads(my_json_str)
is_ok = dct['ok']
client_index = dct['indices']['client_ind_2']['index']
