【问题描述】：

我正在尝试使用 AT&T 语音转文本 API。到目前为止，我可以获得访问令牌

def get_access_token(client_id, client_secret):
headers = 'Content-Type': 'application/x-www-form-urlencoded', 'Accept': 'application/json'

data = 'client_id': client_id, 'client_secret': client_secret, 'scope': 'SPEECH',
        'grant_type': 'client_credentials'

response = requests.post(oauth_url, data=data, headers=headers)
return response.text

到目前为止，这就是我发送音频文件以获取 json 响应的内容：

def get_text_from_file(file, access_token):
headers = 'Authorization': 'Bearer ' + access_token, 'Accept': 'application/json', 'Content-Type': 'audio/wav',
           'X-SpeechContext': 'Generic', 'Connection': 'Keep-Alive'

但我不确定如何发送文件。有人可以帮忙吗？

【参考方案1】：

这是我刚刚开始使用的请求库，以及我将在下面链接的其他一些资源

import json
import requests

class ATTSpeech:
    CLIENT_ID = "SOME"
    CLIENT_SECRET = "ID"
    TOKEN = None

    def __init__(self, *args, **kwargs):
        self.get_token()


    def get_token(self):
        # Get Access Token via OAuth.
        # https://matrix.bf.sl.attcompute.com/apps/constellation-sandbox
        response = requests.post("https://api.att.com/oauth/token", 
            "client_id": self.CLIENT_ID,
            "client_secret": self.CLIENT_SECRET,
            "grant_type": "client_credentials",
            "scope": "SPEECH,STTC"
        )
        content = json.loads(response.content)
        self.TOKEN = content["access_token"]


    def text_from_file(self, path):

        with open(path, 'rb') as f:
            response = requests.post("https://api.att.com/speech/v3/speechToText",
                headers = 
                    "Authorization": "Bearer %s" % self.TOKEN,
                    "Accept": "application/json",
                    "Content-Type": "audio/wav",
                    "X-SpeechContext": "Generic",
            , data=f)
        content = json.loads(response.content)
        return content

用法如下所示，假设您将此文件保存为 ATTEngine

from ATTEngine import ATTSpeech
a = ATTSpeech()
a.text_from_file('/Users/issackelly/Desktop/here.wav')
