我想做的是得到一个 'Site_streetaddress' 的列表，但是我没有成功。
这是我的代码：
import urllib.request
import json
url = 'https://discover.data.vic.gov.au/api/3/action/datastore_search?resource_id=afb52611-6061-4a2b-9110-74c920bede77&limit=5'
response = urllib.request.urlopen(url).read()
jsonResponse = json.loads(response.decode('utf-8'))
print(jsonResponse)
我试过这里的例子，但我没有得到任何结果。 https://www.w3schools.com/python/python_json.asp
请注意，在顶层只有 3 个键。
import urllib.request
import json
url = 'https://discover.data.vic.gov.au/api/3/action/datastore_search?resource_id=afb52611-6061-4a2b-9110-74c920bede77&limit=5'
response = urllib.request.urlopen(url).read()
jsonResponse = json.loads(response.decode('utf-8'))
print([item.get('Site_streetaddress') for item in jsonResponse['result']['records']])
输出
['Corner Victoria Cross Parade & Kelliher Avenue', '50 Kangan Drive\t', 'Corner Bacchua Marsh & Purnell Road', '135 Separation Street', '83C Purnell Road']
作为旁注，我建议使用 requests。安装包后
import requests
url = 'https://discover.data.vic.gov.au/api/3/action/datastore_search?resource_id=afb52611-6061-4a2b-9110-74c920bede77&limit=5'
response = requests.get(url)
data = response.json()
print([item.get('Site_streetaddress') for item in data['result']['records']])
您需要如下遍历 jsonResponse：
import urllib.request
import json
url = 'https://discover.data.vic.gov.au/api/3/action/datastore_search?resource_id=afb52611-6061-4a2b-9110-74c920bede77&limit=5'
response = urllib.request.urlopen(url).read()
jsonResponse = json.loads(response.decode('utf-8'))
for data in jsonResponse['result']['records']:
print ('Site_streetaddress: '+data['Site_streetaddress'])
上面的答案很好。当从 json 中提取数据时，有时您需要 'peel' 它的层。
我的过程是：
> jsonResponse.keys()
dict_keys(['help', 'success', 'result'])
> jsonResponse['result'].keys()
dict_keys(['include_total', 'resource_id', 'fields', 'records_format', 'records', 'limit', '_links', 'total'])
# and so on ... Finally, I suggest
for i in jsonResponse['result']['records']:
print(i["Site_streetaddress"])
等等。我建议：
