我正在使用Python开发应用程序。我必须执行GET请求才能获取特定信息。我的代码是这样的：
...
conn = httplib.HTTPConnection(self.url)
header = {"Authorization":"Bearer "+self.token}
conn.request("GET","/data",headers=header)
...
并且我获得的JSON与此类似（您可以看到有2个很大的不同部分……这只是一个示例，在我的应用程序中，这些部分很多）。

{
"createdAt": "2015-11-26T10:06:05.756Z",
"date": "2015-10-31T23:00:00.000Z",
"files": [],
"id": 1,
"metadata": {},
"notes": "note impianto 1",
"parentSubject": {
"code": "soggetto1",
"createdAt": "2015-11-26T10:05:38.765Z",
"id": 1,
"metadata": {},
"notes": "note soggetto 1",
"personalInfo": 1,
"sex": "M",
"tags": null,
"type": 1,
"updatedAt": "2015-11-26T10:05:38.765Z"
}
},
{
"createdAt": "2015-11-26T10:06:36.684Z",
"date": "2015-11-01T23:00:00.000Z",
"files": [],
"id": 2,
"metadata": {},
"notes": "note impianto 2",
"parentSubject": {
"code": "soggetto1",
"createdAt": "2015-11-26T10:05:38.765Z",
"id": 1,
"metadata": {},
"notes": "note soggetto 1",
"personalInfo": 1,
"sex": "M",
"tags": null,
"type": 1,
"updatedAt": "2015-11-26T10:05:38.765Z"
}
}
]
例如，如果我发出此请求：
...
conn.request("GET","/data?id=1",headers=header)
...
我显然只有第一部分。问题是我不想获取所有具有的数据，id=1而是要获取具有的所有数据code=soggetto1。我能怎么做？
如果API无法做到这一点，那么您必须获取所有数据并自行查找。
在示例中，我将一个代码更改为“ soggetto2”
data = '''[
{
"createdAt": "2015-11-26T10:06:05.756Z",
"date": "2015-10-31T23:00:00.000Z",
"files": [],
"id": 1,
"metadata": {},
"notes": "note impianto 1",
"parentSubject": {
"code": "soggetto2",
"createdAt": "2015-11-26T10:05:38.765Z",
"id": 1,
"metadata": {},
"notes": "note soggetto 1",
"personalInfo": 1,
"sex": "M",
"tags": null,
"type": 1,
"updatedAt": "2015-11-26T10:05:38.765Z"
}
},
{
"createdAt": "2015-11-26T10:06:36.684Z",
"date": "2015-11-01T23:00:00.000Z",
"files": [],
"id": 2,
"metadata": {},
"notes": "note impianto 2",
"parentSubject": {
"code": "soggetto2",
"createdAt": "2015-11-26T10:05:38.765Z",
"id": 1,
"metadata": {},
"notes": "note soggetto 1",
"personalInfo": 1,
"sex": "M",
"tags": null,
"type": 1,
"updatedAt": "2015-11-26T10:05:38.765Z"
}
}
]'''

import json
j = json.loads(data)
results = []
for x in j:
if x["parentSubject"]["code"] == "soggetto1":
results.append(x)
print results
您可以通过列表理解来做到这一点
results = [ x for x in j if x["parentSubject"]["code"] == "soggetto1" ]
或者 filter()
results = filter(lambda x:x["parentSubject"]["code"] == "soggetto1", j)
