python中的谷歌语音API JSON解析？

Question

我得到了google json api的响应，并将文件保存在一个json文件中，如下所示

JSON 文件drive.google.com/open?id=1Esuv9KpikqhwccL-dGm-IFfI5S6V7plV

我想在python 2中解析它。我试过了

for result in response.results:
        # The first alternative is the most likely one for this portion.
        print('Transcript: {}'.format(result.alternatives[0].transcript))
        print('Confidence: {}'.format(result.alternatives[0].confidence))

但它会引发错误

'str' object has no attribute 'results'

后来我试过了

jsondata = json.load(json_file_path)

但它说

'str' object has no attribute 'read'

有什么帮助吗？

Answer 1

试试这个：

data = "your json data" # of type `str`
json_dict = json.loads(data)

for result in json_dict["response"]["results"]:
  if "alternatives" in result:
    alternatives = result["alternatives"][0]
    if "confidence" in alternatives:
      print(alternatives["confidence"])
    if "transcript" in alternatives:
      print(alternatives["transcript"])

• 使用json.loads将str转换/解析为dict

• "alternatives" 的类型为 list

如果您的数据来自 json 文件，请先读取它

with open('data.json', 'r') as f:
    data = f.read()
    # refer to above code
