sql-server - Node mssql 连接错误 : Login failed for user ' '

Question

这是我的代码:

var sql = require("mssql");

var dbConfig = {
server: "server",
username: "user",
password: "password",
database: "database"
};

function getEmp() {
var conn = new sql.Connection(dbConfig);
console.log(conn);
var req = new sql.Request(conn);
conn.connect(function (err) {
    if (err) {
        console.log(err);
        return;
    }
    req.query("SELECT * FROM Alg.User", function (err, recordset) {
        if (err) {
            console.log(err);
            return;
        }
        else {
            console.log(recordset);
        }
        conn.close();
    });
});
}

getEmp();

这是我记录的错误:

 { ConnectionError: Login failed for user ''.

name: 'ConnectionError',
message: 'Login failed for user \'\'.',

有人知道我做错了什么吗？看起来我的变量用户名没有放在连接字符串中？但我不知道为什么...

提前致谢!

解决方案:

问题是在 dbConfig 中，username 变量应该改为 user!而且sql查询也是错误的，应该是[Alg].[User]，因为'User'是关键字!

使用 tedious / msnodesqlv8 driver对于 Windows 为我工作:

代替:

var sql = require("mssql");

我把它改成了:

var sql = require("mssql/msnodesqlv8");

我没有硬编码用户名/密码。

这是我的 dbconfig 的样子:

var db_config = {
  driver: "msnodesqlv8",
  server: "ServerName",
  database: "databaseName",
  options: {
    trustedConnection: true,
    useUTC: true
  }
}
