Question

最初，我尝试使用router.post和router.get方法，并在我的代码中将它们分开。

然后我选择使用router.all，并在同一个函数中单独POST和GET并使用两个res.render和一个共同对象与他们共享的viewData，因为它会加载相同的屏幕。

我想知道这是否是一个很好的方法，以及如何在node.js / express.js中完成：

router.all('/profile', function(req, res, next) {
    var viewData = {
        data1: Demo.getdata(1),
        data2: Demo.getdata(2),
        data3: Demo.getdata(3),
        data4: Demo.getdata(4)
    };

    if (req.method === 'POST') {
        request.get({
            uri: res.locals.baseUrl + '/getData',
            qs: {
                param1: param1
            }
        }, function(error, response, body) {
            if (error || response.statusCode != 200) {
                viewData.message = 'There was a problem!!';
            }
            else{
                var data = JSON.parse(body);
                viewData.message = 'Good job!!';
                viewData.moreData= data.moreData;
            }
            res.render('settings/profile', viewData);
        });

    }
    else{
        res.render('settings/profile', viewData);
    }
});

我建议您将它们分开，因为它们几乎没有任何共同点。

我要做的是避免复制/粘贴代码，SELECT CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'd' THEN SecDebit END AS 'debit', CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN SecCredit END AS 'credit', docdate, DATEDIFF(d,DocDate, GETDATE()) AS days, CASE WHEN DATEDIFF(d,DocDate, GETDATE()) <= 365 THEN CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN -seccredit ELSE SecDebit END END AS 'secdebitlessthen365', CASE WHEN DATEDIFF(d, DocDate, GETDATE()) > 365 AND DATEDIFF(d, DocDate, GETDATE()) <= 730 THEN CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN -seccredit ELSE SecDebit END END AS 'secdebitgreaterthen365lessthenorequa730', CASE WHEN DATEDIFF(d, DocDate, GETDATE()) > 730 AND DATEDIFF(d, DocDate, GETDATE()) <= 1095 THEN CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN -seccredit ELSE SecDebit END END AS 'secdebitgreaterthen730lessthenorequal1095', CASE WHEN DATEDIFF(d, DocDate, GETDATE()) > 1095 THEN CASE WHEN j.DocTypeID=0 AND CreditOrDebit = 'c' THEN -seccredit ELSE SecDebit END END AS 'secdebitgreaterthen1095' FROM J_Transactions (NOLOCK) j WHERE AccountID IN (871446) AND j.DocTypeID=0调用router.post('/profile', ...)，以便在需要时可以回退到res.redirect("/profile");。

发送相同的数据以在POST中查看并在node.js / Express.js中进行GET
