[下面回答问题中的完整教程。欢迎反馈!】
我正在尝试创建一个 AWS Lambda 函数，用于 Amazon Alexa 技能从我的 Netatmo 气象站获取天气信息。基本上，我需要通过 http 请求连接到 Netatmo 云。
这是我的代码片段，http 请求是针对临时访问 token 完成的，请求没问题，但结果正文是 body: {"error":"invalid_request"}。这里可能有什么问题？
var clientId = "";
var clientSecret = "";
var userId="[email protected]";
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();
}
最佳答案
我让它运行了!

}
function buildResponse(sessionAttributes, speechletResponse) {
return {
version: "1.0",
sessionAttributes: sessionAttributes,
response: speechletResponse
};
}
首先，意图模式。这是我的；复制粘贴此代码(并根据需要进行修改):
{
"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。为插槽命名
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，示例语句:
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
