Microsoft-cognitive:Python中的情感API

Question

我在呼吁情感API后得到以下响应。

{
  "FaceRectangle": {
    "Top": 141,
    "Left": 331,
    "Width": 52,
    "Height": 52
  },
  "Scores": {
    "Anger": 0.002451766,
    "Contempt": 0.0005512201,
    "Disgust": 0.0063303886,
    "Fear": 0.000122375583,
    "Happiness": 0.9589189,
    "Neutral": 0.0222537462,
    "Sadness": 0.008983561,
    "Surprise": 0.000388026354
  }
}

如何创建一个变量以保持幸福的分数？以下是Python代码：

import http.client, urllib.request, urllib.parse, urllib.error, base64, sys
headers = {
  key.
  'Content-Type': 'application/octet-stream',
  'Ocp-Apim-Subscription-Key': '************************',
}
params = urllib.parse.urlencode({

    })
body = open('my_image.jpg','rb').read()
try:
    conn = http.client.HTTPSConnection('westus.api.cognitive.microsoft.com')
    conn.request("POST", "/emotion/v1.0/recognize?%s" % params, body, headers)
    response = conn.getresponse()
    data = response.read()
    print(data)
    conn.close()
except Exception as e:
    print(e.args)

Answer 1

我认为这应该有效：

import json
dump = json.dumps(data)
json_string = json.loads(dump)
happiness =  str(json_string[0]['Scores']['Happiness'])

Answer 2

import ast
data = response.read()
b = data.decode("utf-8") #bytes to string conversion
c = ast.literal_eval(b) #string to list conversion
print(c[0]['scores']['happiness']) #parsing
