我是节点新手。无论我想要做什么都是简单的从提交和提交后重定向到特定的模板。这是我的目录结构
这是我的index.js
文件
var app = require('express')();
var http = require('http').Server(app);
var express = require('express')
var bodyParser = require('body-parser')
app.get('/', function(req, res) {
res.sendFile(__dirname + '/login.html');
});
app.post('/login', function(request, response) {
console.log(request.body.user);
console.log(request.body.password);
if (request.body.user === "test@gmail.com" && request.body.password === "123") {
console.log("logged in");
response.statusCode = 200;
response.setHeader("Location", "/home");
response.end();
}
});
app.get('/home', function(req, res) {
res.sendFile(__dirname + '/test.html');
});
http.listen(3001, function() {
console.log('listening on *:3001');
});
在我的login.html
文件中,我有一个简单的表单
<label for="user" class="sr-only">Email address</label>
<input type="email" id="user" class="form-control" name="user[email]" placeholder="Email address" required autofocus autocomplete="on">
<label for="password" class="sr-only">Password</label>
<input type="password" id="password" name="user[password]" class="form-control" placeholder="Password" required>
<div class="checkbox">
<label>
<input type="checkbox" value="remember-me"> Remember me
</label>
</div>
<button class="btn btn-lg btn-primary btn-block" type="button" id="submit">Sign in</button>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script>
$(document).ready(function() {
var user, pass;
$("#submit").click(function(event) {
user = $("#user").val();
pass = $("#password").val();
$.post("/login", {user: user, password: pass}, function(data) {
if (data === 'done')
{
alert("login success");
}
});
});
});
</script>
当我在localhost:3001
login.html
处运行我的应用时,如果我提交的表单包含username:test@gamil.com
和password:123
,则不会重定向到test.html
,虽然我可以阅读控制台消息"logged in"
。

你能尝试使用
吗?app.post('/login', function(request, response) {
console.log(request.body.user);
console.log(request.body.password);
if (request.body.user === "test@gmail.com" && request.body.password === "123") {
console.log("logged in");
response.redirect('/home')
}
});

不要通过AJAX调用(if (!pref.getSectionStatus1()) {
Log.e("Once Again in TableScreenSectionwiseActivity: ", "hmm....");
GetSectionsAsync getSectionsAsync = new GetSectionsAsync(
getActivity());
getSectionsAsync.setFragmentInterfaceCallBack(this);
HashMap<String, String> map = new HashMap<String, String>();
map.put("Location_Name", pref.getLocation());
getSectionsAsync.execute(map);
}
)向@Override
public void onTaskCompleted(HashMap<String, ArrayList<String>> hashMap) {
ids = hashMap.get("ID_LIST");
names = hashMap.get("NAME_LIST");
table_section_adapter adapter = new table_section_adapter(
activity.getApplicationContext(), names, ids);
section_list.setAdapter(adapter);
section_list.setOnItemClickListener(this);
}
发出请求,而是让表单提交给它:
/login
在您目前的情况下,您将 AJAX请求重定向到$.post()
,而不是整个页面。
此外,当用户名和/或密码不匹配时,您的处理程序不执行任何操作,这意味着请求将停止。在这种情况下,您还需要发送回复(可能会重定向到错误页面,或者再次返回到登录页面)。
