Question

module.exports.login = function (request, response, next) {
if (request.body.user && request.body.password) {
    response.end('submitted');
} else {
    common.render('login', function (error, file) {
        if (error) {
            next(error);
        } else {
            response.writeHead(200, 'OK', { 'Content-Type': 'text/html' });
            var stream = fs.createReadStream(file);
            stream.pipe(response);
        }
    });
}
};

我正在使用connect body-parser。当我第一次打开这个应用程序时，我看到登录表单 - 很好，但是当我提交表单时，我在控制台中看到405方法不允许错误。我试图添加一些标题，但它不起作用。有人可以帮忙吗？

我认为语法应该是：

module.exports = function(request, response, next) {
if (request.body.user && request.body.password) {
    response.end('submitted');
} else {
    common.render('login', function (error, file) {
        if (error) {
            next(error);
        } else {
            response.writeHead(200, 'OK', { 'Content-Type': 'text/html' });
            var stream = fs.createReadStream(file);
            stream.pipe(response);
        }
    });
}
};

或

function login(request, response, next) {
if (request.body.user && request.body.password) {
    response.end('submitted');
} else {
    common.render('login', function (error, file) {
        if (error) {
            next(error);
        } else {
            response.writeHead(200, 'OK', { 'Content-Type': 'text/html' });
            var stream = fs.createReadStream(file);
            stream.pipe(response);
        }
    });
}
};
module.exports = login;

我终于解决了它。问题是WITH first_posts AS ( SELECT p.id AS post_id, COUNT(c.id) AS comment_id, p.user_id, p.body, p.created_at FROM (SELECT * FROM posts ORDER BY id LIMIT 3) AS p LEFT JOIN comments AS c ON p.id = c.post_id GROUP BY 1, 3, 4, 5 ) SELECT post_id, comment_id, user_id, body, created_at FROM ( SELECT 1 AS type, post_id, comment_id, user_id, body, created_at, 0 AS r FROM first_posts UNION ALL SELECT 2 AS type, p.post_id, c.id, c.user_id, c.body, c.created_at, ROW_NUMBER() OVER (PARTITION BY p.post_id ORDER BY c.id) AS r FROM first_posts AS p INNER JOIN comments AS c ON p.post_id = c.post_id ORDER BY post_id, type, comment_id ) AS f WHERE r <= 3;和serve-static。它写了一些额外的标题，如允许的方法！

NodeJS方法不允许
