下面的代码用get方法在网页中能显示，并且提交url会改变，但是改为post后在网页主页中点击链接打开subform网页就报404错误。 //form.ejs
<!DOCTYPE html> <html> <head> <title><%= title %></title> <link rel='stylesheet' href='/stylesheets/style.css' /> </head> <body> 首页如何提交表单并接收参数?
如何使用session?
如何使用cookies?
如何字符串加密? <form method="post"> 用户名：<input type="text" id="txtUserName" name="txtUserName" /> 密码：<input type="password" id="txtUserPwd" name="txtUserPwd" /> <input type="submit" value="提交"> </form> </body> </html> /***********************************************************/ //form.js var express = require('express'); var router = express.Router(); router.post('/', function(req, res) { var userName = req.body.txtUserName, userPwd = req.body.txtUserPwd, userName2 = req.param('txtUserName'), userPwd2 = req.param('txtUserPwd'); console.log('req.body用户名:'+userName); console.log('req.body密码:'+userPwd); console.log('req.param用户名:'+userName2); console.log('req.param密码:'+userPwd2); res.render('subform', { title: '提交表单及接收参数示例' }); }); module.exports = router; /***************************************************/ 主页点击链接就出错，其他的连接都有用： Not Found

@THCloud你好，我是刚学node.js。我再在路由中加入一个get方法就可以运行了，运行的是post方法，为什么会这样呢？get方法可以单独运行，但是用post方法也需要把get方法同样的路径写到路由中
