继续上一篇Stateless的博文，在上一篇的博文的基础上稍微加点东西
接下来右键解决方案添加新项目，一样建一个空的Web项目
然后在StatelessDemoWeb项目里面添加Views文件夹，Scripts文件夹，并在Views文件夹里面添加index，login，secure三个页面
在index页面添加如下代码
<body>
<div id="loggedIn" style="display:none;"><p>欢迎<span id="username">.</span><a href="#" id="logout">登出</a></p></div>
<h1>非安全页面</h1>
<p><a href="secure.html">安全页面</a></p>
<script type="text/javascript">
$(document).ready(function () {
var apiToken = ApiToken.Get();
if (apiToken.IsValid) {
$("#loggedIn").show();
$("#username").html(apiToken.Username);
$("#logout").click(function () {
var request = { apiKey: apiToken.Key };
var success = function () {
ApiToken.Delete();
window.location = "index.html";
};
$.ajax({
type: ‘DELETE‘,
url: api.auth,
data: request,
success: sucess,
dataType: "json"
});
});
}
});
</script>
</body>
在login页面添加如下代码
<body>
<div>
<input type="text" id="Username" placeholder="登陆名"/><br />
<input type="password" id="Password" placeholder="密码"/><br />
<input id="RememberMe" type="checkbox" value="True"/><br />
<button id="submitButton">登陆</button>
</div>
<div id="errorBox" style="display:none">
无效的用户名和密码
<script type="text/javascript">
$(document).ready(function () {
$("#submitButton").click(function () {
$("#errorBox").hide();
var authRequest = {
username: $("#Username").val(),
password: $("#Password").val(),
rememberMe: $("RememberMe").val()
};
var success = function (response) {
ApiToken.Set(authRequest.username, response.ApiKey, authRequest.rememberMe);
window.location = "index.html";
};
var error = function () {
$("#errorBox").show();
};
$.ajax({
type: ‘POST‘,
url: api.auth,
data: authRequest,
success: success,
error: error,
dataType: "json"
});
});
});
</script>
</div>
</body>
在secure页面添加如下代码
<body style="display:none">
<div>
<a href="index.html"><<主页</a>
<div id="loggedIn" style="display:none">
<p>欢迎<span id="username"></span>.<a href="#" id="logout">登出</a></p>
</div>
<h1>安全页面</h1>
<div>安全内容:<span id="secureContent" class="secure"></span></div>
<div>
<input type="text" id="newusername" placeholder="用户名"/><br />
<input id="newpassword" type="password" placeholder="密码"/><br />
<input type="button" onclick="createUser()"/>
<div id="createuserresult"></div>
</div>
</div>
<script type="text/javascript">
$(document).ready(function () {
//如果 apiKey 存在, 则表示用户已登录
//检查 apiKey 是否存在
var apiToken = ApiToken.Get();
if (apiToken.IsValid) {
//用户已登录
//获取和显示安全内容
//使用我们存储在 cookie 中的 apiKey
var request = { apiKey: apiToken.Key };
//成功视图
var success = function (response) {
$("#username").html(apiToken.Username);
$("#secureContent").html(response.SecureContent);
$("body").show();
};
//将用户重定向到401上的登录页
var error = function (response) {
if (response.status == 401) {
window.location = "login.html";
return;
}
alert("出问题了" + response.error);
};
$.ajax({
url: api.secure,
data: request,
success: success,
error: error,
dataType:"json"
});
}
else {
//如果没有保存 apiToken, 则表示用户尚未登录
//将 "em 打包" 发送到登录页
window.location = "login.html";
}
if (apiToken.IsValid) {
$("#loggedIn").show();
$("#username").html(apiToken.Username);
$("#logout").click(function () {
//将 apiKey 发送到要销毁的 api
var request = { apiKey: apiToken.Key };
//当契约在服务器上完成时,
//删除客户端中的 cookie, 然后重定向到主页。
var success = function () {
apiToken.Delete();
window.location = "index.html";
};
$.ajax({
type: ‘DELETE‘,
url: api.auth,
data: resquest,
dataType: "json"
});
});
}
});
function createUser() {
var apiToken = ApiToken.Get();
if (apiToken.IsValid) {
//用户已登录
var request = {
username: $("#newusername").val(),
password: $("#newpassword").val()
};
//成功视图
var success = function (response) {
$("#createuserresult").html("用户" + response.username + "已创建");
};
//将用户重定向到401上的登录页
var error = function (response) {
if (response.status == 401) {
window.location = "login.html";
return;
}
alert("出问题了" + response.error);
};
$.ajax({
type: "POST",
url: api.create_user + "?ApiKey=" + apiToken.Key,
data: request,
success: success,
error: error,
dataType:"json"
});
}
else {
//如果没有保存 apiToken, 则表示用户尚未登录
//将 "em 打包" 发送到登录页
window.location = "login.html";
}
}
</script>
</body>
然后在script文件夹添加api.js,apiToken.js两个文件，然后修改api.js文件如下
var api = {
auth: "http://localhost:9611/restApi/auth",
secure: "http://localhost:9611/restApi/secure",
create_user:"http://localhost:9611/resApi/secure/create_user"
};
apiToken.js文件添加如下代码
var apiKeyKey = "sample_apiKey";
var usernameKey = "sample_username";
var ApiToken = {
Set: function (username, apiKey, rememberMe) {
var days = rememberMe ? 10 : 0;
createCookie(apiKeyKey, apiKey, days);
createCookie(usernameKey,username,days);
},
Get: function ()
{
var key = readCookie(apiKeyKey);
var username = readCookie(usernameKey);
var token = { Key: key, Username: username, IsValid: key != null };
return token;
},
Delete: function ()
{
eraseCookie(apiKeyKey);
eraseCookie(usernameKey);
}
};
function createCookie(name,value,days)
{
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 1000));
var expires = ";expires=" + date.toGMTString();
} else {
var expires = "";
document.cookie = name + "=" + value + expires + ";path=/";
console.log(document.cookie);
}
}
function readCookie(name) {
var cookieValue = null;
var nameEQ = name + "=";
var ca = document.cookie.split(‘;‘);
for (var i = 0; i < ca.length; i++) {
var c = cap[i];
while (c.charAt(0) == ‘ ‘) {
c = c.substring(1, c.length);
}
if (c.indexOf(nameEQ) == 0) {
var found = c.substring(nameEQ.length, c.length);
cookieValue = found;
}
}
return cookieValue;
}
function eraseCookie(name) {
createCookie(name,"",-1);
}
