Question

我正在使用python为Assistat app创建webhook。我可以向用户询问位置许可，但是一旦用户同意，我会收到以下错误

UnparseableJsonResponse
API Version 2: Failed to parse JSON response string with 'INVALID_ARGUMENT' error: ": Cannot find field.".

我已经检查了我的webhook服务器，但没有请求。这似乎是API.ai方面的一些问题。
以下是使用Python客户端时来自Actions控制台的Debug响应

使用Python库Flask-Assistant

如何解决此问题？

更新 Node JS客户端工作...... Python客户端有什么问题？

请求从Actions服务器到我的Node JS webhook服务器

{ originalRequest: 
   { source: 'google',
     version: '2',
     data: 
      { isInSandbox: true,
        surface: [Object],
        inputs: [Array],
        user: [Object],
        device: [Object],
        conversation: [Object] } },
  id: '<ID>',
  timestamp: '2017-09-06T05:43:21.342Z',

  result: 
   { source: 'agent',
     resolvedQuery: 'actions_intent_PERMISSION',
     speech: '',
     action: 'DefaultWelcomeIntent.DefaultWelcomeIntent-fallback',
     actionIncomplete: false,
     parameters: {},
     contexts: [ [Object], [Object], [Object], [Object], [Object] ],

API.ai意图设置

Answer 1

您没有在网络上点击任何内容的最可能原因是您没有注册获得回复的意图。

您可以通过创建一个将事件设置为actions_intent_PERMISSION的意图来实现此目的。

另见SO上的以下答案：

Google API版本2上的API.ai操作：无法使用＆＃39; INVALID_ARGUMENT＆＃39;解析JSON响应字符串错误：＆＃34;：无法找到字段。＆＃34;
