Question

我在访问MYSQL时遇到了麻烦。

我的代码中有一个GET METHOD：

app.get

执行该方法时，出现错误：

    app.get('/users',function(request,response){
    client.query('select * from User where 1=1',function(error,result){
        if(error){
            response.json('unfortunately fail');
            console.log('unfortunately fail , error : %s',error);
            console.log('error stack: %s',error.stack);
            console.log('error message: %s',error.message);
            throw error;
        }else{
            console.log('select success....');
            response.json('select success....');
            response.json(result);
        }
    });
});

这是关于变量（express，mysql ...）

 unfortunately fail , error : Error: getaddrinfo ENOTFOUND
error stack: Error: getaddrinfo ENOTFOUND

Answer 1

您的mysql数据库连接的host设置不正确（getaddrinfo为ENOTFOUND表示DNS解析失败）。它只需要是mysql服务器的主机名（例如nodejs.somewhere.com）。

节点JS错误＆＃34; getaddrinfo ENOTFOUND＆＃34;
