[Full tutorial in the answered question below. Feedback welcome!]
我正在尝试创建一个AWS Lambda函数，用于Amazon Alexa技能从我的Netatmo weatherstation获取天气信息。基本上，我需要通过http请求连接到Netatmo云。
I am trying to create an AWS Lambda function to use for an Amazon Alexa skill to fetch weather information from my Netatmo weatherstation. Basically, I need to connect to the Netatmo cloud via http request.
这是我的代码片段，http请求是针对临时访问令牌完成的，请求没问题，但结果正文是正文：{error：非法请求}。这可能是什么问题？
Here's a snippet of my code, the http request is done for the temporary access token, the request is ok but the result body is body: {"error":"invalid_request"}. What could be the problem here?
var clientId = "";
var clientSecret = "";
var userId="a@google.ro";
var pass="";
function getNetatmoData(callback, cardTitle){
var sessionAttributes = {};
var formUserPass = { client_id: clientId,
client_secret: clientSecret,
username: userId,
password: pass,
scope: 'read_station',
grant_type: 'password' };
shouldEndSession = false;
cardTitle = "Welcome";
speechOutput ="";
repromptText ="";
var options = {
host: 'api.netatmo.net',
path: '/oauth2/token',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'client_id': clientId,
'client_secret': clientSecret,
'username': userId,
'password': pass,
'scope': 'read_station',
'grant_type': 'password'
}
};
var req = http.request(options, function(res) {
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log("body: " + chunk);
});
res.on('error', function (chunk) {
console.log('Error: '+chunk);
});
res.on('end', function() {
speechOutput = "Request successfuly processed."
console.log(speechOutput);
repromptText = ""
callback(sessionAttributes, buildSpeechletResponse(cardTitle, speechOutput, repromptText, shouldEndSession));
});
});
req.on('error', function(e){console.log('error: '+e)});
req.end();
}
推荐答案
我让它运行了！
这是一个快速演练：
I got it running! Here's a quick walkthrough :
-
获取Amazon AWS的免费帐户。只要您的技能不能持续运行（您将通过AWS服务器上使用的运行时间和资源（每月700个免费小时）收费，您应该保持良好状态并且保持免费。该技能一次需要1-3秒。
Get a free account for Amazon AWS. As long as your skill is not constantly running (you will be billed by the run time and resources used on the AWS Servers with something like 700? free hours each month), you should be good and it will stay free. The skill requires 1-3 seconds to run at a time.
在Amazon Web Services（AWS）中设置新的lambda函数。每次调用技能时都会执行此功能。
Set up a new lambda function in Amazon Web Services (AWS). This function will execute every time the skill is invoked.

Go到netatmo的开发者网站（ https://dev.netatmo.com/ ）并创建一个新的应用程序。这将是您在Netatmo端传感器数据的接口。该应用程序将具有唯一的id（即：5653769769f7411515036a0b）和客户机密码（即：T4nHevTcRbs053TZsoLZiH1AFKLZGb83Fmw9q）。 （不，这些数字不代表有效的客户ID和秘密，它们仅用于演示目的）
Go to netatmo's developer site (https://dev.netatmo.com/) and create a new application. This will be your interface to the sensor data on the Netatmo side. The apllication will have a unique id (i.e: 5653769769f7411515036a0b) and client secret (i.e: T4nHevTcRbs053TZsoLZiH1AFKLZGb83Fmw9q). (No, these numbers do not represent a valid client id and secret, they are only for demonstration purposes)
填写所需的凭证（netatmo帐户用户和传递，客户ID和秘密）在上面的代码中。
Fill in the required credentials (netatmo account user and pass, client id and secret) in the code above.
转到亚马逊应用和服务（ https://developer.amazon.com/edw/home.html ）。在菜单中，选择Alexa，然后选择Alexa Skills Kit（点击开始使用）
Go to Amazon Apps and Services (https://developer.amazon.com/edw/home.html). In the Menu, select Alexa and then Alexa Skills Kit (click on Get started)
现在您需要创建一个新技能。给你的技能一个名字和调用。该名称将用于调用（或启动）应用程序。在Endpoint字段中，您需要提供之前创建的lambda函数的ARN id。这个号码可以在右上角显示lambda功能的网页上找到。它应该是这样的：arn：aws：lambda：us-east-1：255569121831：function：[你的函数名]。完成此步骤后，左侧将显示绿色复选标记以指示进度（进度菜单）。
Now you need to create a new Skill. Give your skill a name and invokation. The name will be used to invoke (or start) the application. In the Endpoint field you need to give in the ARN id of your lambda function created earlier. This number can be found on the webpage displaying your lambda function, on the top right corner. It should be something like : arn:aws:lambda:us-east-1:255569121831:function:[your function name]. Once you completed this step, a green checkmark will appear to the left to indicate progress (progress menu).
下一阶段涉及设置交互模型。它负责将话语映射到意图和插槽。
首先是Intent Schema。这是我的;复制粘贴此代码（并根据需要进行修改）：
The next phase involves setting up the interaction model. It is responsible with mapping of utterences to intents and slots. First, the Intent Schema. Here's mine; copy-paste this code (and modify if needed):
{
"intents":
[
{
"intent": "AskTemperature",
"slots": [
{
"name": "Location",
"type": "LIST_OF_LOCATIONS"
}
]
},
{
"intent": "AskCarbonDioxide",
"slots": [
{
"name": "Location",
"type": "LIST_OF_LOCATIONS"
}
]
},
{
"intent": "AskHumidity",
"slots": [
{
"name": "Location",
"type": "LIST_OF_LOCATIONS"
}
]
},
{
"intent": "AskRain",
"slots": []
},
{
"intent": "AskSound",
"slots": []
},
{
"intent": "AskWind",
"slots": []
},
{
"intent": "AskPressure",
"slots": []
}
]
}
接下来，自定义插槽类型。单击添加插槽类型。给插槽命名
Next, the Custom Slot Types. Click on Add Slot Type. Give the slot the name
LIST_OF_LOCATIONS and newline-separated : DefaultAll, Inside, Outside, Living, Bedroom, Kitchen, Bathroom, Alpha, Beta
（用换行符替换逗号）
接下来，示例说明：
AskTemperature what's the temperature {Location}
AskTemperature what's the temperature in {Location}
AskTemperature what's the temperature in the {Location}
AskTemperature get the temperature {Location}
AskTemperature get the temperature in {Location}
AskTemperature get the temperature in the {Location}
AskCarbonDioxide what's the comfort level {Location}
AskCarbonDioxide what's the comfort level in {Location}
AskCarbonDioxide what's the comfort level in the {Location}
AskCarbonDioxide get the comfort level {Location}
AskCarbonDioxide get the comfort level in {Location}
AskCarbonDioxide get the comfort level in the {Location}
AskHumidity what's the humidity {Location}
AskHumidity what's the humidity in {Location}
AskHumidity what's the humidity in the {Location}
AskHumidity get the humidity {Location}
AskHumidity get the humidity from {Location}
AskHumidity get the humidity in {Location}
AskHumidity get the humidity in the {Location}
AskHumidity get humidity
AskRain is it raining
AskRain did it rain
AskRain did it rain today
AskRain get rain millimeter count
AskRain get rain
AskSound get sound level
AskSound tell me how loud it is
AskWind is it windy
AskWind get wind
AskWind get wind measures
AskWind get direction
AskWind get speed
AskPressure get pressure
AskPressure what's the pressure

可以留下测试，描述和发布信息空白，除非您计划将您的技能发送到亚马逊，以便可以公开发布。我把我的空白留了下来：）
The Test, Description and Publishing information can be left blank, unless you plan to send your skill to amazon so as it can be made publicly available. I left mine blank. :)
几乎就在那里。你只需要启用新技能。转到 http://alexa.amazon.com/ ，然后在左侧菜单中选择技能。找到您的技能并单击启用。
Almost there. You just need to enable the new skill. Go to http://alexa.amazon.com/ and in the left menu, select Skills. Find your skill and click enable.
真是太棒了。说Alexa，打开[你的技能名称]。默认情况下，室内和室外温度应从netatmo云中提取并由Alexa大声读出。你也可以说Alexa，打开[你的技能名称]并获得卧室的温度。正如您可能已经注意到的那样，获取[位置]中的温度部分对应于您之前填写的样本。
That awesome moment. Say "Alexa, open [your skill name]." By default, the indoor and outdoor temperature should be fetched from the netatmo cloud and read out loud by Alexa. you can also say "Alexa, open [your skill name] and get the temperature in the bedroom.". As you already might have noticed, the part " get the temperature in the [Location]" corresponds to the sample uttereces you filled in earlier.
