/**
`Promise.all` accepts an array of promises, and returns a new promise which
is fulfilled with an array of fulfillment values for the passed promises, or
rejected with the reason of the first passed promise to be rejected. It casts all
elements of the passed iterable to promises as it runs this algorithm.
Example:
```javascript
let promise1 = resolve(1);
let promise2 = resolve(2);
let promise3 = resolve(3);
let promises = [ promise1, promise2, promise3 ];
Promise.all(promises).then(function(array){
// The array here would be [ 1, 2, 3 ];
});
```
If any of the `promises` given to `all` are rejected, the first promise
that is rejected will be given as an argument to the returned promises's
rejection handler. For example:
Example:
```javascript
let promise1 = resolve(1);
let promise2 = reject(new Error("2"));
let promise3 = reject(new Error("3"));
let promises = [ promise1, promise2, promise3 ];
Promise.all(promises).then(function(array){
// Code here never runs because there are rejected promises!
}, function(error) {
// error.message === "2"
});
```

@static
@param {Array} entries array of promises
@param {String} label optional string for labeling the promise.

`Promise.race` returns a new promise which is settled in the same way as the
first passed promise to settle.
Example:
```javascript
let promise1 = new Promise(function(resolve, reject){

}, 200);
});
let promise2 = new Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 2');
}, 100);
});
Promise.race([promise1, promise2]).then(function(result){
// result === 'promise 2' because it was resolved before promise1
// was resolved.
});
```
`Promise.race` is deterministic in that only the state of the first
settled promise matters. For example, even if other promises given to the
`promises` array argument are resolved, but the first settled promise has
become rejected before the other promises became fulfilled, the returned
promise will become rejected:
```javascript
let promise1 = new Promise(function(resolve, reject){
setTimeout(function(){
resolve('promise 1');
}, 200);
});
let promise2 = new Promise(function(resolve, reject){
setTimeout(function(){
reject(new Error('promise 2'));
}, 100);
});
Promise.race([promise1, promise2]).then(function(result){
// Code here never runs
}, function(reason){
// reason.message === 'promise 2' because promise 2 became rejected before
// promise 1 became fulfilled
});
```

```javascript
Promise.race([ajax('foo.json'), timeout(5000)])
```

/**
Promise objects represent the eventual result of an asynchronous operation. The
primary way of interacting with a promise is through its `then` method, which
registers callbacks to receive either a promise's eventual value or the reason
why the promise cannot be fulfilled.
Terminology
-----------
- `promise` is an object or function with a `then` method whose behavior conforms to this specification.
- `thenable` is an object or function that defines a `then` method.
- `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
- `exception` is a value that is thrown using the throw statement.
- `reason` is a value that indicates why a promise was rejected.
- `settled` the final resting state of a promise, fulfilled or rejected.
A promise can be in one of three states: pending, fulfilled, or rejected.
Promises that are fulfilled have a fulfillment value and are in the fulfilled
state. Promises that are rejected have a rejection reason and are in the
rejected state. A fulfillment value is never a thenable.
Promises can also be said to *resolve* a value. If this value is also a
promise, then the original promise's settled state will match the value's
settled state. So a promise that *resolves* a promise that rejects will
itself reject, and a promise that *resolves* a promise that fulfills will
itself fulfill.
Basic Usage:
------------
```js
let promise = new Promise(function(resolve, reject) {
// on success
resolve(value);
// on failure
reject(reason);
});
promise.then(function(value) {
// on fulfillment
}, function(reason) {
// on rejection
});
```
Advanced Usage:
---------------
Promises shine when abstracting away asynchronous interactions such as
`XMLHttpRequest`s.
```js
function getJSON(url) {
return new Promise(function(resolve, reject){
let xhr = new XMLHttpRequest();
xhr.open('GET', url);
xhr.onreadystatechange = handler;
xhr.responseType = 'json';
xhr.setRequestHeader('Accept', 'application/json');
xhr.send();
function handler() {
if (this.readyState === this.DONE) {
if (this.status === 200) {
resolve(this.response);
} else {
reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
}
}
};
});
}
getJSON('/posts.json').then(function(json) {
// on fulfillment
}, function(reason) {
// on rejection
});
```
Unlike callbacks, promises are great composable primitives.
```js
Promise.all([
getJSON('/posts'),
getJSON('/comments')
]).then(function(values){
values[0] // => postsJSON
values[1] // => commentsJSON
return values;
});
```
@class Promise
@param {Function} resolver
Useful for tooling.
@constructor
*/
var Promise$2 = function () {
function Promise(resolver) {
this[PROMISE_ID] = nextId();
this._result = this._state = undefined;
this._subscribers = [];
if (noop !== resolver) {
typeof resolver !== 'function' && needsResolver();
this instanceof Promise ? initializePromise(this, resolver) : needsNew();
}
}
/**
The primary way of interacting with a promise is through its `then` method,
which registers callbacks to receive either a promise's eventual value or the
reason why the promise cannot be fulfilled.
```js
findUser().then(function(user){
// user is available
}, function(reason){
// user is unavailable, and you are given the reason why
});
```
Chaining
--------
The return value of `then` is itself a promise. This second, 'downstream'
promise is resolved with the return value of the first promise's fulfillment
or rejection handler, or rejected if the handler throws an exception.
```js
findUser().then(function (user) {
return user.name;
}, function (reason) {
return 'default name';
}).then(function (userName) {
// If `findUser` fulfilled, `userName` will be the user's name, otherwise it
// will be `'default name'`
});
findUser().then(function (user) {
throw new Error('Found user, but still unhappy');
}, function (reason) {
throw new Error('`findUser` rejected and we're unhappy');
}).then(function (value) {
// never reached
}, function (reason) {
// if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
// If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
});
```
If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
```js
findUser().then(function (user) {
throw new PedagogicalException('Upstream error');
}).then(function (value) {
// never reached
}).then(function (value) {
// never reached
}, function (reason) {
// The `PedgagocialException` is propagated all the way down to here
});
```
Assimilation
------------
Sometimes the value you want to propagate to a downstream promise can only be
retrieved asynchronously. This can be achieved by returning a promise in the
fulfillment or rejection handler. The downstream promise will then be pending
until the returned promise is settled. This is called *assimilation*.
```js
findUser().then(function (user) {
return findCommentsByAuthor(user);
}).then(function (comments) {
// The user's comments are now available
});
```
If the assimliated promise rejects, then the downstream promise will also reject.
```js
findUser().then(function (user) {
return findCommentsByAuthor(user);
}).then(function (comments) {
// If `findCommentsByAuthor` fulfills, we'll have the value here
}, function (reason) {
// If `findCommentsByAuthor` rejects, we'll have the reason here
});
```
Simple Example
--------------
Synchronous Example
```javascript
let result;
try {
result = findResult();
// success
} catch(reason) {
// failure
}
```
Errback Example
```js
findResult(function(result, err){
if (err) {
// failure
} else {
// success
}
});
```
Promise Example;
```javascript
findResult().then(function(result){
// success
}, function(reason){
// failure
});
```
Advanced Example
--------------
Synchronous Example
```javascript
let author, books;
try {
author = findAuthor();
books = findBooksByAuthor(author);
// success
} catch(reason) {
// failure
}
```
Errback Example
```js
function foundBooks(books) {
}
function failure(reason) {
}
findAuthor(function(author, err){
if (err) {
failure(err);
// failure
} else {
try {
findBoooksByAuthor(author, function(books, err) {
if (err) {

} else {
try {
foundBooks(books);
} catch(reason) {
failure(reason);
}
}
});
} catch(error) {
failure(err);
}
// success
}

2. 在表示层和组件层分别添加Nuget包
注：(vs2.1版本安装Microsoft.AspNetCore.SignalR1.0.1版本)
3. 在组件层新建一个NotificationHub类
public class NotificationHub : Hub
{
///
/// 建立连接时触发
///
///
/// 离开连接时触发
///
///
///
/// 向所有人推送消息
///
///
///
/// 向指定组推送消息
///
///
///
///
/// 加入指定组并向组推送消息
///
///
///
/// 退出指定组并向组推送消息
///
///
///
/// 向指定Id推送消息
///
/// 要推送消息的对象
///
/// 4. 在表示层下Startup类中的ConfigureServices方法下添加注册signalr服务代码
//注册signalr服务
services.AddSignalR();5. 在表示层下Startup类中的Configure方法下添加注册signalr中间件代码
//注册signalr中间件
app.UseSignalR(route=>
{
route.MapHub("/notifyHub");
}); 6. 在表示层下的Account文件夹中Login.cshtml页面建立、开启连接
//创建连接
const connection = new signalR.HubConnectionBuilder().
withUrl("/notifyHub").build();
//开启连接
connection.start().catch(err => console.error(err.toString()));7. 在表示层中AccountController控制器下注入接口连接
//注入连接
private IHubContext _hubContext;
public AccountController(IAdminInfoService adminInfoService, IHubContext hubContext)
{
_adminInfoService = adminInfoService;
_hubContext = hubContext;
} 8.1 在表示层中AccountController控制器下的ValidateLogin验证登录方法下发送系统公告---广播
//发送一个系统公告
await _hubContext.Clients.All.SendAsync("ReceiveMessage","今天周五！");8.2 在表示层中AccountController控制器下的ValidateLogin验证登录方法下发送单条信息---单点
//单点
identity.AddClaim(new Claim(ClaimTypes.NameIdentifier,adminInfo.AdminId.ToString()));
//好友上线
await _hubContext.Clients.User("3").SendAsync("ReceiveMessage",$"你的好友{userName}上线了！");8.3 在表示层中AccountController控制器下添加定时器、发信息方法并在ValidateLogin验证登录方法下调用定时器方法---轮播
///
/// 定时器
///
///
/// 发信息
///
/// 
9. 在表示层下的Home文件夹中Index.cshtml页面创建websocket连接、接收信息、开启连接
