我在Heroku上运行一个简单的Node.js服务器。我已经设置了一个Azure SQL数据库,我只想尝试从服务器建立与它的连接。我使用tedious.js进行连接。据我所知,我遵循文档中的模式,但连接并没有通过。这是我的代码(更改了用户名和密码)。现在,连接函数在对" / data"的GET请求时被调用。我的浏览器页面,但页面永远不会加载,连接永远不会通过。有什么指针吗?
var azure = require("azure-storage");
var Connection = require("tedious").Connection;
var config = {
Server : "cultureofthefewpractice.database.windows",
username : "XXXXX",
password : "XXXXX",
options : {
port: 1433,
Database : "cultureofthefewpracticedatabase",
connectTimeout : 3000,
},
};
var connection = new Connection(config);
function connect(request, response) {
connection.on("connect", function(error) {
//If no error, then good to go
console.log("Connected to database! Booyah.");
executeStatement();
response.send("Connected to database! Booyah.");
}, function (info) {
console.log(info);
});
}
exports.connect = connect;

我回应社区提供的答案。这是一个可以帮助您入门的快速代码示例 -
var Connection = require('tedious').Connection;
var config = {
userName: 'yourusername',
password: 'yourpassword',
server: 'yourserver.database.windows.net',
// When you connect to Azure SQL Database, you need these next options.
options: {encrypt: true, database: 'AdventureWorks'}
};
var connection = new Connection(config);
connection.on('connect', function(err) {
// If no error, then good to proceed.
console.log("Connected");
executeStatement();
//executeStatement1();
});
var Request = require('tedious').Request;
var TYPES = require('tedious').TYPES;
function executeStatement() {
request = new Request("SELECT TOP 10 Title, FirstName, LastName from SalesLT.Customer;", function(err) {
if (err) {
console.log(err);}
});
var result = "";
request.on('row', function(columns) {
columns.forEach(function(column) {
if (column.value === null) {
console.log('NULL');
} else {
result+= column.value + " ";
}
});
console.log(result);
result ="";
});
request.on('done', function(rowCount, more) {
console.log(rowCount + ' rows returned');
});
connection.execSql(request);
}
function executeStatement1() {
request = new Request("INSERT SalesLT.Product (Name, ProductNumber, StandardCost, ListPrice, SellStartDate) OUTPUT INSERTED.ProductID VALUES (@Name, @Number, @Cost, @Price, CURRENT_TIMESTAMP);", function(err) {
if (err) {
console.log(err);}
});
request.addParameter('Name', TYPES.NVarChar,'SQL Server Express 2014');
request.addParameter('Number', TYPES.NVarChar , 'SQLEXPRESS2014');
request.addParameter('Cost', TYPES.Int, 11);
request.addParameter('Price', TYPES.Int,11);
request.on('row', function(columns) {
columns.forEach(function(column) {
if (column.value === null) {
console.log('NULL');
} else {
console.log("Product id of inserted item is " + column.value);
}
});
});
connection.execSql(request);
}
关于防火墙规则,它取决于您运行应用程序的位置。如果您在Heroku上运行它,则必须添加Heroku服务器的IP。它是Linux VM吗?这是您可能想要查看的堆栈溢出answer。
答案 1 :(得分:0)
首先:连接字符串必须为cultureofthefewpractice.database.windows.net
- 您最后会遗漏.net
。
第二步:打开SQL数据库服务器的防火墙,以允许来自节点服务器的流量(流量来自的任何IP地址)。 SQL数据库允许您指定IP范围(和多个范围)。
