Question

我有一个可以运行python的应用程序，但是我想将语音识别的结果传递给我不知道如何的呼叫者，我已经尝试了一切。我什至试图通过在顶部声明lastRes不起作用来将lastRes设置为全局变量

lastRes = ""
app = Flask(__name__)

@app.route("/voice", methods=['GET', 'POST'])
def voice():
  resp = VoiceResponse()
  resp.say("What is your name?")
  print ("1---------------")
  resp.gather(input='speech', timeout="3", action='/gather', method='POST')
  #resp.append(gather)
  print ("2---------------")
  return str(resp)

@app.route("/mainFlow", methods=['GET', 'POST'])
def mainFlow():
  resp = VoiceResponse()
  resp.say("We are done?")
  print("5--------------->" + str(lastRes))
  return str(resp)

@app.route("/gather", methods=['GET', 'POST'])
def gather():
  resp = VoiceResponse()
  print("3---------------")
  lastRes = request.values.get("SpeechResult", "")
  print("4--------------->" + str(lastRes))
  resp.redirect('/mainFlow')
  return str(resp)

if __name__ == "__main__":
  lastRes = ""
  app.run(debug=True)

如何将lastRes传递给例程/ mainFlow？

这里是Twilio开发人员的传播者。

首先，我想问一下为什么要在使用结果之前尝试重定向。您在/gather端点中已经有语音结果，为什么不响应呢？像这样：

@app.route("/gather", methods=['GET', 'POST'])
def gather():
  resp = VoiceResponse()
  lastRes = request.values.get("SpeechResult", "")
  resp.say('Thank you ' + lastRes + '.')
  resp.redirect('/mainFlow')
  return str(resp)

此响应将说出“谢谢”，然后说出语音结果，然后重定向到主流。

或者，您正在使用URL。您可以将响应设置为URL参数，如下所示：

import urllib

@app.route("/gather", methods=['GET', 'POST'])
def gather():
  resp = VoiceResponse()
  SpeechResult = request.values.get("SpeechResult", "")
  params = urllib.urlencode({"SpeechResult": SpeechResult})
  resp.redirect('/mainFlow?' + params)
  return str(resp)

然后，您可以像下面这样在SpeechResult中使用mainFlow：

@app.route("/mainFlow", methods=['GET', 'POST'])
def mainFlow():
  SpeechResult = request.args.get('SpeechResult')
  resp = VoiceResponse()
  resp.say("We are done? " + SpeechResult)
  return str(resp)

最后，您也可以在会话中设置SpeechResult，因为在通话过程中也可以保持该结果。

from flask import Flask, session, request

@app.route("/gather", methods=['GET', 'POST'])
def gather():
  resp = VoiceResponse()
  session['SpeechResult'] = request.values.get("SpeechResult", "")
  resp.redirect('/mainFlow')
  return str(resp)

@app.route("/mainFlow", methods=['GET', 'POST'])
def mainFlow():
  SpeechResult = session['SpeechResult']
  resp = VoiceResponse()
  resp.say("We are done? " + SpeechResult)
  return str(resp)

让我知道是否有帮助。
