[英]Google Action / Dialogflow : how to ask for geolocation
I'm trying to implement a simple app for Google Assistant.我正在尝试为 Google Assistant 实现一个简单的应用程序。 All works fine, but now I have a problem with the "permission" helper : https://developers.google.com/actions/assistant/helpers#helper_intents
一切正常,但现在我遇到了“权限”助手的问题: https : //developers.google.com/actions/assistant/helpers#helper_intents
I have an intent connected with webhook to my java application.我有一个将 webhook 连接到我的 java 应用程序的意图。 When an user types a sentence similar to "near to me", I want to ask to him his location and then use
lat/lon
to perform a search.当用户输入类似于“靠近我”的句子时,我想询问他的位置,然后使用
lat/lon
执行搜索。
es: Brazilian restaurant near to me es:我附近的巴西餐厅
my intent "searchRestaurant" is fired我的意图“searchRestaurant”被解雇
I receive the webhook request and I parse it我收到 webhook 请求并解析它
if I find a parameter that is connected to a sentence like "near to me", so instead to response with a "Card" or a "List" I return a JSON that represent the helper request :如果我发现一个参数连接到像“near to me”这样的句子,而不是用“Card”或“List”响应,我会返回一个代表帮助请求的JSON:
{
"conversationToken": "[]",
"expectUserResponse": true,
"expectedInputs": [
{
"inputPrompt": {
"initialPrompts": [
{
"textToSpeech": "PLACEHOLDER_FOR_PERMISSION"
}
],
"noInputPrompts": []
},
"possibileIntents": [
{
"intent": "actions.intent.PERMISSION",
"inputValueData": {
"@type": "type.googleapis.com/google.actions.v2.PermissionValueSpec",
"optContext": "Posso accedere alla tua posizione?",
"permission": [
"NAME",
"DEVICE_PRECISE_LOCATION"
]
}
}
]
}
]
}
but something seems to be wrong, and I receive an error:但似乎有问题,我收到一个错误:
"{\\n \\"responseMetadata\\": {\\n \\"status\\": {\\n \\"code\\": 10,\\n \\"message\\": \\"Failed to parse Dialogflow response into AppResponse because of empty speech response\\",\\n \\"details\\": [{\\n \\"@type\\": \\"type.googleapis.com/google.protobuf.Value\\",\\n \\"value\\": \\"{\\\\"id\\\\":\\\\"1cc45c5e-c398-4ea7-98a5-408f31ce142d\\\\",\\\\"timestamp\\\\":\\\\"2018-08-02T14:45:05.752Z\\\\",\\\\"lang\\\\":\\\\"it\\\\",\\\\"result\\\\":{},\\\\"alternateResult\\\\":{},\\\\"status\\\\":{\\\\"code\\\\":206,\\\\"errorType\\\\":\\\\"partial_content\\\\",\\\\"errorDetails\\\\":\\\\"Webhook call failed.

"{\\n \\"responseMetadata\\": {\\n \\"status\\": {\\n \\"code\\": 10,\\n \\"message\\": \\"由于为空,无法将 Dialogflow 响应解析为 AppResponse语音回复\\",\\n \\"details\\": [{\\n \\"@type\\": \\"type.googleapis.com/google.protobuf.Value\\",\\n \\"value\\": \\" {\\\\"id\\\\":\\\\"1cc45c5e-c398-4ea7-98a5-408f31ce142d\\\\",\\\\"timestamp\\\\":\\\\"2018-08-02T14:45:05.752Z\\\\", \\\\"lang\\\\":\\\\"it\\\\",\\\\"result\\\\":{},\\\\"alternateResult\\\\":{},\\\\"status\\\\":{\\\\" code\\\\":206,\\\\"errorType\\\\":\\\\"partial_content\\\\",\\\\"errorDetails\\\\":\\\\"Webhook 调用失败。错误:无法解析 webhook JSON 响应:找不到字段:消息google.cloud.dialogflow.v2.WebhookResponse.\\\\"},\\\\"sessionId\\\\":\\\\"1533221100163\\\\"}\\"\\n }]\\n }\\n }\\n} 中的对话令牌”
The "conversationToken" is filled, so I don't understand the error message. “conversationToken”已填写,所以我不明白错误信息。 Maybe I'm trying to perform the operation in a wrong way.
也许我试图以错误的方式执行操作。
So, which is the correct way to call this helper?那么,调用这个助手的正确方法是什么?
--> I've created a second intent " askGeolocation
" that have "actions_intent_PERMISSION"
as "Event", and ... if I understand correctly the documentation, should be trigger if the request for helper is correct. --> 我创建了第二个意图“
askGeolocation
”,将"actions_intent_PERMISSION"
作为“事件”,并且...如果我正确理解文档,如果对帮助程序的请求正确,则应该触发。
How can I get this working?我怎样才能让它工作?
UPDATE :更新 :
I find some example of the json response for ask permission and seems that it should be different from the one above that i'm using :我找到了一些请求许可的 json 响应示例,似乎它应该与我正在使用的上面的不同:
https://github.com/dialogflow/fulfillment-webhook-json/blob/master/responses/v2/ActionsOnGoogle/AskForPermission.json https://github.com/dialogflow/fulfillment-webhook-json/blob/master/responses/v2/ActionsOnGoogle/AskForPermission.json
{
"payload": {
"google": {
"expectUserResponse": true,
"systemIntent": {
"intent": "actions.intent.PERMISSION",
"data": {
"@type": "type.googleapis.com/google.actions.v2.PermissionValueSpec",
"optContext": "To deliver your order",
"permissions": [
"NAME",
"DEVICE_PRECISE_LOCATION"
]
}
}
}
}
}
so, i've implemented it and now the response seems to be good (no more error on parsing it), but i still receive an error on it validation :所以,我已经实现了它,现在响应似乎很好(解析它时不再出错),但我仍然收到验证错误:
UnparseableJsonResponse API Version 2: Failed to parse JSON response string with 'INVALID_ARGUMENT' error: "permission: Cannot find field." UnparseableJsonResponse API 版本 2:无法解析带有“INVALID_ARGUMENT”错误的 JSON 响应字符串:“权限:找不到字段。”
so, a problem still persist.所以,问题仍然存在。 Anyone know the cause?
有谁知道原因吗?
Thanks谢谢
After some tests i found the problem.经过一些测试,我发现了问题。 I was returning a wrong json repsonse with "permission" instead of "permissions":
我用“权限”而不是“权限”返回了错误的json响应:
"permission**s**": [
"NAME",
"DEVICE_PRECISE_LOCATION"
]
So the steps to ask for location are correct.所以询问位置的步骤是正确的。 I report them here as a little tutorial in order to help who is facing on it for the first time:
我将它们作为一个小教程在这里报告,以帮助第一次面对它的人:
1) In DialogFlow, add some logic to your Intent, in order to understand when is ok to ask to user his location. 1) 在 DialogFlow 中,为您的 Intent 添加一些逻辑,以了解何时可以询问用户他的位置。 In my case, i've added a "parameter" that identify sentences like "nearby" and so on.
就我而言,我添加了一个“参数”,用于标识“附近”等句子。
2) When my Intent is fired i receive to my java application a request like this : 2)当我的 Intent 被触发时,我会收到我的 Java 应用程序这样的请求:
...
"queryResult": {
"queryText": "ristorante argentino qui vicino",
"action": "bycategory",
"parameters": {
"askgeolocation": "qui vicino",
"TipoRistorante": ["ristorante", "argentino"]
},
...
3) If "askgeolocation" parameter is filled, instead to return a "simple message" o other type of message, i return a json for ask the permission to geolocation : 3)如果填充了“askgeolocation”参数,而不是返回“简单消息”或其他类型的消息,我会返回一个json以请求地理定位的许可:
{
"payload": {
"google": {
"expectUserResponse": true,
"systemIntent": {
"intent": "actions.intent.PERMISSION",
"data": {
"@type": "type.googleapis.com/google.actions.v2.PermissionValueSpec",
"optContext": "To deliver your order",
"permissions": [
"NAME",
"DEVICE_PRECISE_LOCATION"
]
}
}
}
}
}
4) You MUST have a second Intent that is configured with "actions_intent_PERMISSION " event : 4) 你必须有第二个 Intent 配置了“actions_intent_PERMISSION”事件:
But with Fulfillment active :但是在实现活跃的情况下:
5) Once your response arrive to Google Assistant this is the message that appear : 5) 一旦您的回复到达 Google 助理,就会出现以下消息:
6) Now, if user answer "ok" you receive this json on your webhook : 6) 现在,如果用户回答“ok”,你会在你的 webhook 上收到这个 json:
{
"responseId": "32cf46cf-80d8-xxxxxxxxxxxxxxxxxxxxx",
"queryResult": {
"queryText": "actions_intent_PERMISSION",
"action": "geoposition",
"parameters": {
},
"allRequiredParamsPresent": true,
"fulfillmentMessages": [{
"text": {
"text": [""]
}
}],
"outputContexts": [{
"name": "projects/xxxxxxxxxxxxxxxxxxxxx"
}, {
"name": "projects/xxxxxxxxxxxxxxxxxxxxx",
"parameters": {
"PERMISSION": true
}
}, {
"name": "projects/xxxxxxxxxxxxxxxxxxxxx"
}, {
"name": "projects/xxxxxxxxxxxxxxxxxxxxx"
}, {
"name": "projects/xxxxxxxxxxxxxxxxxxxxx"
}, {

}],

"payload": {
"isInSandbox": true,
"surface": {
"capabilities": [{

}, {

}, {
"name": "actions.capability.AUDIO_OUTPUT"
}, {
"name": "actions.capability.WEB_BROWSER"
}]
},
"requestType": "SIMULATOR",
"inputs": [{
"rawInputs": [{
"inputType": "KEYBOARD"
}],
"arguments": [{
"textValue": "true",
"name": "PERMISSION",
"boolValue": true
}],
"intent": "actions.intent.PERMISSION"
}],
"user": {
"lastSeen": "2018-08-03T08:55:20Z",
"permissions": ["NAME", "DEVICE_PRECISE_LOCATION"],
"profile": {
"displayName": ".... full name of the user ...",
"givenName": "... name ...",
"familyName": "... surname ..."
},
"locale": "it-IT",
"userId": "xxxxxxxxxxxxxxxxxxxxx"
},
"device": {
"location": {
"coordinates": {
"latitude": 45.xxxxxx,
"longitude": 9.xxxxxx
}
}
},
"conversation": {
"conversationId": "xxxxxxxxxxxxxxxxxxxxx",
"type": "ACTIVE",
"conversationToken": "[]"
},
"availableSurfaces": [{
"capabilities": [{
"name": "actions.capability.SCREEN_OUTPUT"
}, {
"name": "actions.capability.AUDIO_OUTPUT"
}, {
"name": "actions.capability.WEB_BROWSER"
}]
}]
}
},
"session": "projects/xxxxxxxxxxxxxxxxxxxxx"
}
that contains, name/surname and latitude/longitude.包含姓名/姓氏和纬度/经度。 This information can be saved in your application, in order to not perform again this steps.
可以将此信息保存在您的应用程序中,以免再次执行此步骤。
I hope this helps.我希望这有帮助。

In your intent, you can ask for a parameter with a custom Entity.在您的意图中,您可以使用自定义实体请求参数。 This you can do like this:
