使用 mysql npm 模块（版本 2.13.0）连接到 Azure Database for MySQL 时出现错误：

错误：

代码：

var mysql = require("mysql");
var fs = require("fs");

var connection = mysql.createConnection({
    host: "host",
    user: "user@db",
    password: "pw",
    database: "scheme",
    port: 3306,
    ssl: {
        ca: fs.readFileSync(__dirname + "/cert.pem")
    },
    insecureAuth: true
});

connection.connect();

connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
    if (error) throw error;
    console.log('The solution is: ', results[0].solution);
});

connection.end();

通过 MySQL Workbench 连接到数据库工作正常。

这是一个已知问题，因为我们的工程师在https://social.msdn.microsoft.com/Forums/en-US/c8fedbcc-909d-41ce-8c72-0374f76fdf82/cannot-connect-from-nodejs?forum=AzureDatabaseforMySQL 进行了讨论。

目前，我已经在Cannot connect Azure Web App - NodeJS to Azure Mysql 测试了@Bradley Grainger 提供的解决方案。我们也可以在https://github.com/mysqljs/mysql/commit/e3e123e9af7c0829a6c1417d911572a75b4a5f95 看到要点。

目前请将package.json修改为：

"dependencies": {
    "mysql": "git://github.com/mysqljs/mysql#e3e123e9af7c0829a6c1417d911572a75b4a5f95"
  },

然后，运行npm install 来安装这个版本。

它应该按预期工作。

另外，请等待维护者合并此PR。
