嗨我真的不知道如何解決這個問題。在Lambda中測試時,我不斷收到多個驗證錯誤。我在四處搜尋,有人說要更新到我所做的最新SDK,但仍然收到相同的錯誤。我試過在新的AWS.DynamoDB.DocumentClient()中使用其他apis;但是這只是在我的日誌中返回undefined。如何讓我的代碼從DynamoDB查詢?DynamoDB查詢錯誤:多個驗證錯誤
'use strict';
var APP_ID = "amzn1.echo-sdk-ams.app.ca7e2a16-1bf9-4b5b-8a7e-8c15fb0ccd9d";
var AlexaSkill = require('./AlexaSkill');
var SatTracker = function() {
AlexaSkill.call(this, APP_ID);
};
var AWS = require('aws-sdk');
AWS.config.update({region: 'us-east-1'});
var doc = require("dynamodb-doc");
var dynamodb = new AWS.DynamoDB.DocumentClient();
function getZipcode(zipcode) {
var queryParams = {
TableName : "ZipcodeUSA",
KeyConditionExpression: "#zc = :zip",
ExpressionAttributeNames:{
"#zc": "zipcode"
},
ExpressionAttributeValues:{
":zip":zipcode
}
};
console.log("about to start dynamoDB query with zipcode: " + zipcode);
dynamodb.query(queryParams, function(err, data) {
if (err) {
console.log("error in dynamo.query of getZipcode funtion: " + err);
} else {
var zipData;
console.log("starting dynamoDB query with zipcode: " + zipcode);
if (data && data.Items && data.Items.length > 0) {
console.log("Found " + data.Items.length + " matching zipcode");
if (data.Items.length === 1) {
zipData = data.Items[0];
return zipData;
}
}
}
console.log("completed dynamo.query with zipcode: " + err);
});
}
你得到什麼錯誤? –
我得到一個multiplevalidationerror但現在查詢只是停在未定義。 –
