源代码（登陆页面）：<form action = "../users/login" name = "loginForm" method="post">

登录
email:	<input type="text" name = "email" class = "form-control" placeholder="文本输入">
密码：	<input type="password" name = "pwd" class = "form-control"placeholder="密码">
<input type="hidden" name = "subflag" value = "1" > <input type="submit" value = "登录" class = "btn btn-success">

        </form>

路由设置：router.all('/login', function(req, res) {

subflag = req.body['subflag'];
if(subflag == undefined){
    res.render('login');
}
else{
    userModel.login(req.res);
}

});
登陆判断：login:function(req,res){

    pool = connPool();登陆

    pool.getConnection(function(err,conn){
        if(err){
            res.send('获取连接错误，错误原因：' + err.message);
            return;
        }

        var userSql = 'select uid,nicheng from user where email = ? and pwd = ?';
        var param = [req.body["email"],req.body["pwd"]];email
        conn.query(userSql,param,function(err,rs){
            if(err){
                res.send("数据库连接错误，错误原因：" + err.message);
                return;
            }
            console.log('输出结果集：' + rs);
            if(rs.length > 0){

                res.send("登录成功！");
            }
            else{
                res.send("email/密码错误");
            }
        });
        conn.release();
    })

}

我在测试的时候，抛出错误 不能读取未定义属性"email"
我尝试过添加
var bodyParser = require（'body-parser'）;
app.use（bodyParser（））;
但是都没有解决 这是怎么个问题？

Answer 1

var param = [req.body["email"],req.body["pwd"]];email你这个分号后面多了个email啊。。

Answer 2

req['body'] undefined
可以把req打印出来console.log(req);

Answer 3

错误代码serModel.login(req.res);正确代码userModel.login(req,res)；参数传递的时候 把 逗号打成了英文句号 改成这样就好了
