如何从 JSON 响应中获取特定值 - Python

Question

我开始使用 python，现在我正尝试从 REST 中检索一些值，但是我收到一个错误

Traceback (most recent call last):
  File "h:\DESKTOP\test_check\check_securityPrices.py", line 69, in <module>
    jsonPath = r["assetPricing"]["instrumentId"]
TypeError: list indices must be integers or slices, not str

这是我得到的 JSON 响应：

到目前为止，这是我的代码。

# # Request to get the instrumentID from CDW
listInstrumentID = []
securityPricesCDW = f"https://svc-uat-cdw/cdw/securityPrices/{dateinplay}?limit=10"

r = requests.get(securityPricesCDW).json()

# print(r)
jsonPath = parse("$..'m:assetPricing'[*].'m:pricingSource'[*].'m:instrumentId'[*].'#value'")

for match in jsonPath.find(r):
    print(f"match id: {match.value}")
   thisdict = match.value
   listInstrumentID.append(thisdict)

无论如何，如果有人能帮我得到对象数组的所有值'instrumentId' 'm:instrumentId'：[{ '#value': '100001380992', '_instrumentIdScheme': 'mhi:MHILIST'

感谢您的任何建议

Answer 1

试试下面的方法（假设 data 是来自 post 的字典列表）

ids = [x['m:assetPricing'][0]['m:instrumentId'][0]['#value'] for x in data]
print(ids)

输出

['100001380992', '100001380993', '100001380994', '100001380995', '100001380996', '100001380997', '100001380999', '100001381000', '100001381004', '100001381005']

Answer 2

你可以试试这个：

from xml.etree import ElementTree

root = ElementTree.parse(url_of_your_file).getroot()

for found in root.findall("m:assetPricing")
    print(found.find("m:instrumentId").text)
