Question

python怎么从调用api返回的数据中取出指定值?

{"TextDetections": [{"DetectedText": "8my7", "Confidence": 99, "Polygon": [{"X": 12, "Y": 8}, {"X": 90, "Y": 8}, {"X": 90, "Y": 32}, {"X": 12, "Y": 32}], "AdvancedInfo": "{\"Parag\":{\"ParagNo\":1}}"}], "Language": "zh", "RequestId": "3a758f25-f8dd-48cb-8cc7-220d82bd6fcf"}
返回的json值，怎么只提出里面的DetectedText下的值：8my7

Answer 1

返回的什么类型的数据，就用什么类型的变量去接收就行了，不太懂你的意思。

Answer 2

import json
s = r'{"TextDetections": [{"DetectedText": "8my7", "Confidence": 99, "Polygon": [{"X": 12, "Y": 8}, {"X": 90, "Y": 8}, {"X": 90, "Y": 32}, {"X": 12, "Y": 32}], "AdvancedInfo": "{\"Parag\":{\"ParagNo\":1}}"}], "Language": "zh", "RequestId": "3a758f25-f8dd-48cb-8cc7-220d82bd6fcf"}'
j = json.loads(s)
print(j['TextDetections'][0]['DetectedText'])

不好意思，我是用腾讯云返回json值，然后我想要值里面的DetectedText值。你那个方法还是不行！
