将Node.js BOT连接到MS Azure SQL数据库

标签: node.js azure-sql-database botframework microsoft-teams

我有一个用Node.js编写的MS Teams bot。机器人会询问一系列问题,并且最后通过访问会话变量来显示最终的响应。一切都很好。

现在我尝试将会话变量存储在MS Azure SQL DB中。数据库在Azure中正确设置,因为我可以在SSMS中访问和向其写入数据。但我相信我可能在我的机器人代码中错误地连接到数据库。我正在使用的机器人代码来自:

connecting to SQL using Node.js

该代码对我有意义。但是我如何在我的机器人中使用该代码?这是我到目前为止所尝试的......

目前我正在使用本地内存MemoryBotStorage()并设置为。

var inMemoryStorage = new builder.MemoryBotStorage();
.set('storage', inMemoryStorage)

在处理Azure Cosmos数据库的另一个Microsoft article中,它指出“4.指定您要使用自定义数据库而不是内存存储。”所以我从中推断出我将实例化的sql db添加到.set('storage',DB Goes Here)但我的尝试失败了,我不确定我是否正确?

所以我的问题是如何从我的机器人代码中正确访问Azure sql server DB - 这是我提供的链接,甚至是正确的方法?

谢谢

注意 - 此代码sample对我有用 - 我能够连接和查询我的Azure数据库 - 但它只是数据库代码,并没有考虑机器人代码。

编辑 - 代码:

const builder = require('botbuilder');
const builderTeams = require('botbuilder-teams');
const restify = require('restify');

const connector = new builderTeams.TeamsChatConnector(
    {

        appId: "My app ID,
        appPassword: "My App PW",
    }

);

var inMemoryStorage = new builder.MemoryBotStorage();


const bot = new builder.UniversalBot(connector, [
    function (session) {
    session.send("Welcome.");
    builder.Prompts.text(session, "Question1?");
},
function (session, results) {
    session.dialogData.question1 = results.response;
    builder.Prompts.text(session, "Question2?");
},
function (session, results) {
    session.dialogData.Question2 = results.response;
    builder.Prompts.text(session, "Question3?");
},
function (session, results) {
    session.dialogData.Question3 = results.response;

    // Begin DB

    var Connection = require('tedious').Connection;
    var config = {
        userName: 'myusername',
        password: 'mypw',
        server: 'myserver.database.windows.net',
        // If you are on Azure SQL Database, you need these next options.  
        options: { encrypt: true, database: 'mydb' }
    };
    var connection = new Connection(config);
    connection.on('connect', function (err) {
        // If no error, then good to proceed.  
        console.log("Connected");
        executeStatement1();
    });

    var Request = require('tedious').Request
    var TYPES = require('tedious').TYPES;

    function executeStatement1() {
        request = new Request("INSERT my (Username, Question1, Question2, Question3, StatusDate) VALUES (@Username, @Question1, @Question2, @Question3, CURRENT_TIMESTAMP);", function (err) {
            if (err) {
                console.log(err);
            }
        });
        request.addParameter('Username', TYPES.NVarChar, session.userData.userName);
        request.addParameter('Question1', TYPES.NVarChar, session.dialogData.Question1);
        request.addParameter('Question2', TYPES.NVarChar, session.dialogData.Question2);
        request.addParameter('Question3', TYPES.NVarChar, session.dialogData.Question3);
        request.on('row', function (columns) {
            columns.forEach(function (column) {
                if (column.value === null) {
                    console.log('NULL');
                } else {
                    console.log("ID of inserted item is " + column.value);
                }
            });
        });
        connection.execSql(request);

    // End DB


    // Process request and display details
    session.endDialog();
}
]).set('storage', inMemoryStorage)


const server = restify.createServer();
server.post('api/messages', connector.listen());
server.listen(portnumber)

使用npm start运行时出错:

npm start

我能够使用此tutorial来解决这个问题。还要感谢Marc LeFleur。

答案 0 :(得分:1)

你有几个错别字。例如,您错过了"上的结束appId

const connector = new builderTeams.TeamsChatConnector(
    {    
        appId: "My app ID",
        appPassword: "My App PW",
    }

);

您也无法在<{1}}函数的中声明function executeStatement1() {...}函数。这需要存在于构造函数之外,而IDialogWaterfallStep调用
