1 | # Cancellations. Отмена асинхронных операций | |
|
|
2 | ||
|
|
3 | Использование Promise позволяет организовать обработку результатов работы | |
|
|
4 | асинхронных фукнций. Ключевые слова async/await позволяют работать с | |
|
|
5 | асинхронными вызовами в стиле процедурного программирования, хотя по сути это | |
|
|
6 | событиный подход. При всей своей красоте даннго подхода в нем умышленно | |
|
|
7 | отсутсвует механизм отмены асинхронной операции, т.е. ее можно начать, но нельзя | |
|
|
8 | отказаться от результатов ее выполнения, даже если это уже не требуется. | |
|
|
9 | ||
|
|
10 | Примером того, когда может потребоваться отмена является загрузка большого | |
|
|
11 | файла, при которой пользователю отображается окно хода операции с возможностью | |
|
|
12 | ее отмены. | |
|
|
13 | ||
|
|
14 | ```ts | |
|
|
15 | // имеется некоторый HTTP клиент | |
|
|
16 | let client = new HttpClient(); | |
|
|
17 | ||
|
|
18 | // загружается большой файл, с использованием медленного канала | |
|
|
19 | let data = await client.getJsonAsync('http://host/large-file.json'); | |
|
|
20 | ||
|
|
21 | ``` | |
|
|
22 | ||
|
|
23 | Как поступить в данной ситуации, прежде всего нужно, чтобы сама операция | |
|
|
24 | поддерживала возможность отмены, предположим, что для этого есть метод | |
|
|
25 | `client.abort()`. | |
|
|
26 | ||
|
|
27 | ```ts | |
|
|
28 | ||
|
|
29 | // имеется некоторый HTTP клиент | |
|
|
30 | let client = new HttpClient(); | |
|
|
31 | ||
|
|
32 | // отображаем окно с информацией о ходе операции | |
|
|
33 | let progressView = showProgress("Downloading, please wait..."); | |
|
|
34 | ||
|
|
35 | // код оборачивается в try/finally поскольку созданную форму нужно закрыть | |
|
|
36 | try { | |
|
|
37 | // загружается большой файл, с использованием медленного канала | |
|
|
38 | // здесь, в отличии от предыдущего примера, мы не дожидаемся результата, | |
|
|
39 | // а запоминаем обещание в переменную downloadTask | |
|
|
40 | let downloadTask = client.getJsonAsync('http://host/large-file.json'); | |
|
|
41 | ||
|
|
42 | // связываем событие нажатия кнопки с отменой загрузки | |
|
|
43 | progressView.once('cancel', () => client.abort()); | |
|
|
44 | ||
|
|
45 | // ожидаем окончания загрузки данных | |
|
|
46 | ||
|
|
47 | let data = await downloadTask; | |
|
|
48 | } finally { | |
|
|
49 | // независимот от результата закрываем форму | |
|
|
50 | // при этом также происходит ануллирование подписок на события | |
|
|
51 | progressView.close(); | |
|
|
52 | } | |
|
|
53 | ||
|
|
54 | ``` | |
|
|
55 | ||
|
|
56 | Технические приведенное решение выглядит не плохо, но проблемы появляются, когда | |
|
|
57 | требуется организовать отмену нескольких операций, особенно если они вложенные. | |
|
|
58 | ||
|
|
59 | ```ts | |
|
|
60 | // обновление информации о человеке на форме | |
|
|
61 | async function updatePersonInfo(info) { | |
|
|
62 | let client = new RestApiClient(); | |
|
|
63 | ||
|
|
64 | // выплнение нескольких асинхронных операций | |
|
|
65 | let org = await client.getOrgAsync(info.orgId); | |
|
|
66 | let city = await client.getCityAsync(info.cityId); | |
|
|
67 | ||
|
|
68 | // обновление содержимого представления | |
|
|
69 | renderContent({ | |
|
|
70 | person: info, | |
|
|
71 | org: org, | |
|
|
72 | city: city | |
|
|
73 | }); | |
|
|
74 | } | |
|
|
75 | ||
|
|
76 | ``` | |
|
|
77 | ||
|
|
78 | Чтобы реализовать возможность отмены такой операции требуется, чтобы в логике | |
|
|
79 | самой операции была реализована поддержка отмены. Для реализации этого | |
|
|
80 | потребуется чтобы у операции была информация о запросе отмены, причем данная | |
|
|
81 | информация относится именно к текущей операции. | |
|
|
82 | ||
|
|
83 | Информацию о состоянии запроса на отмену назовём **маркер отмены (cancellation | |
|
|
84 | token)**. Поскольку маркер отмены тесно связан с операцией, его удобно | |
|
|
85 | передавать в виде параметра, тогда код операции будет выглядеть так: | |
|
|
86 | ||
|
|
87 | ```ts | |
|
|
88 | // обновление информации о человеке на форме | |
|
|
89 | // ct - маркер отмены | |
|
|
90 | async function updatePersonInfo(info, ct) { | |
|
|
91 | let client = new RestApiClient(); | |
|
|
92 | ||
|
|
93 | // выплнение нескольких асинхронных операций | |
|
|
94 | // маркер отмены просто передается далее по цепочке вызовов, без | |
|
|
95 | // дополнительных действий | |
|
|
96 | let org = await client.getOrg(info.orgId, ct); | |
|
|
97 | let city = await client.getCity(info.cityId, ct); | |
|
|
98 | ||
|
|
99 | // обновление содержимого представления | |
|
|
100 | renderContent({ | |
|
|
101 | person: info, | |
|
|
102 | org: org, | |
|
|
103 | city: city | |
|
|
104 | }); | |
|
|
105 | } | |
|
|
106 | ||
|
|
107 | /////////////////////////////////////////////////////////////////////////////// | |
|
|
108 | // ... где-то в другом месте | |
|
|
109 | /////////////////////////////////////////////////////////////////////////////// | |
|
|
110 | ||
|
|
111 | // отображаем окно с информацией о хоже операции | |
|
|
112 | let progressView = showProgress("Loading, please wait..."); | |
|
|
113 | ||
|
|
114 | // создаем маркер отмены для операции на основе события 'cancel'. | |
|
|
115 | let ct = new Cancellation(cancel => progressView.on('cancel', cancel)); | |
|
|
116 | ||
|
|
117 | // код оборачивается в try/finally поскольку созданную форму нужно закрыть | |
|
|
118 | try { | |
|
|
119 | // асинхронно получаем информацию о человеке | |
|
|
120 | let data = await getPersonInfo(personId, ct); | |
|
|
121 | ||
|
|
122 | // асинхронно обновляем представление | |
|
|
123 | await updatePersonInfo(data, ct); | |
|
|
124 | } finally { | |
|
|
125 | // независимот от результата закрываем форму | |
|
|
126 | // при этом также происходит ануллирование подписок на события | |
|
|
127 | progressView.close(); | |
|
|
128 | } | |
|
|
129 | ||
|
|
130 | ``` | |
|
|
131 | ||
|
|
132 | Таким образом тот, кто начинает асинхронную операцию заранее определяет как эта | |
|
|
133 | опреция будет отменена. | |
|
|
134 | ||
|
|
135 | Важно понимать, что для реализации отмены операции | |
|
|
136 | могут выделаться ресурсы требующие явного освобождения (DOM, таймеры, события), | |
|
|
137 | об их освобождении по окончанию операции (успешном или нет) должен позаботиться | |
|
|
138 | инициатор этой операции. `Cancellation` выступает только в роли посредника для | |
|
|
139 | доставки события отмены операции до конечного получателя, он не отслеживает и | |
|
|
140 | не освобождает ресурсы, кроме того, асинхронная операция может его попросту | |
|
|
141 | проигнорировать. | |
|
|
142 | ||
|
|
143 | ## `ICancellation` Маркер отмены операции | |
|
|
144 | ||
|
|
145 | Интерфейс маркера отмены операции. Используется асинхронными операциями, чтобы | |
|
|
146 | получить оповещение о требуемой отмене. | |
|
|
147 | ||
|
|
148 | ### `isSupported(): boolean` | |
|
|
149 | ||
|
|
150 | Определяет, может ли быть запрошена отмена операции через данный маркер. | |
|
|
151 | ||
|
|
152 | ### `isRequested(): boolean` | |
|
|
153 | ||
|
|
154 | Возвращает текущее состояние запроса на отмену. | |
|
|
155 | ||
|
|
156 | ### `throwIfRequested(): void` | |
|
|
157 | ||
|
|
158 | Если отмена была запрошена, бросает в качестве исключения причину отмены. | |
|
|
159 | ||
|
|
160 | ### `register(cb: (e:any) => void): IDestroyable` | |
|
|
161 | ||
|
|
162 | Метод, зарегистрировать обработчик на запрос отмены. Если отмена была запрошена | |
|
|
163 | зарегистрированный обработчик будет вызван ровно один раз, независимо от того, | |
|
|
164 | был ли он зарегистрирован до или после запроса отмены. | |
|
|
165 | ||
|
|
166 | Если отмена уже была запрошена, обработчик будет вызван сразу при регистрации, | |
|
|
167 | при этом исключения, которые могу возникнуть в обработчике не будут обработаны, | |
|
|
168 | а передадуться наверх. | |
|
|
169 | ||
|
|
170 | Вызов данного метода приводит к выделению ресурсов, поэтому операция, | |
|
|
171 | зарегистрировавшая обработчик должна освободить подписку, которую вернет метод. | |
|
|
172 | ||
|
|
173 | ```ts | |
|
|
174 | async function getAsync(url: string, ct: ICancellation = Cancellation.none) { | |
|
|
175 | // переменная в которой будет запомнена подписка на запрос отмены | |
|
|
176 | let reg; | |
|
|
177 | try { | |
|
|
178 | // оборачиваем операцию загрузки в Promise | |
|
|
179 | return await new Promise<string>((resolve, reject) => { | |
|
|
180 | // объект Xhr | |
|
|
181 | const xhr = new XMLHttpRequest(); | |
|
|
182 | xhr.open("GET", url); | |
|
|
183 | ||
|
|
184 | // регистрируем обработчики Promise | |
|
|
185 | xhr.onload = () => resolve(xhr.responseText); | |
|
|
186 | xhr.onerror = () => reject(xhr.statusText); | |
|
|
187 | ||
|
|
188 | // отправляем запрос | |
|
|
189 | xhr.send(); | |
|
|
190 | ||
|
|
191 | // подписываемся на запрос отмены | |
|
|
192 | reg = ct.register((e) => { | |
|
|
193 | reject(e); | |
|
|
194 | xhr.abort(); | |
|
|
195 | }); | |
|
|
196 | }); | |
|
|
197 | } finally { | |
|
|
198 | if (reg) | |
|
|
199 | reg.destroy(); | |
|
|
200 | } | |
|
|
201 | } | |
|
|
202 | ||
|
|
203 | ``` | |
|
|
204 | ||
|
|
205 | Использование метода `register()` предполагается для организации отмены операций | |
|
|
206 | не поддерживающих маркеры отмены. | |
|
|
207 | ||
|
|
208 | ## `Cancellation` Источник отмены | |
|
|
209 | ||
|
|
210 | Класс используется для создания маркеров отмены. Позволяет создать маркер при | |
|
|
211 | начале асинхронной операции и связать его, например, с событием DOM. | |
|
|
212 | ||
|
|
213 | Также маркер можно создавать, когда требуется сложное условие отмены текущей и | |
|
|
214 | всех нижележещих операций. | |
|
|
215 | ||
|
|
216 | Как правило в большинстве операций достаточно маркера переданного в параметрах, | |
|
|
217 | этот же маркер может передаваться ниже. | |
|
|
218 | ||
|
|
219 | ### `constructor(exec: (cancel: (reason:any) => void ) => void )` | |
|
|
220 | ||
|
|
221 | Создает новый маркер, при помощи параметра и инициализирует его при помощи | |
|
|
222 | фукнции, переданной в параметре `exec`. | |
|
|
223 | ||
|
|
224 | ```ts | |
|
|
225 | ||
|
|
226 | let htimer; | |
|
|
227 | let ct = new Cancellation(cancel => { | |
|
|
228 | htimer = setTimeout(() => cancel("The request is timed out."), 1000); | |
|
|
229 | }); | |
|
|
230 | ||
|
|
231 | try { | |
|
|
232 | let text = await getAsync(url, ct); | |
|
|
233 | } finally { | |
|
|
234 | // инициатор должен освобождать ресурсы | |
|
|
235 | // передача недействительного htimer не приводит ни к каким последствиям | |
|
|
236 | clearTimeout(htimer); | |
|
|
237 | } | |
|
|
238 | ||
|
|
239 | ``` | |
|
|
240 | ||
|
|
241 | ## `Cancellation.none: ICancellation` | |
|
|
242 | ||
|
|
243 | Статическое свойство только для чтения, в котором находится специальный токен | |
|
|
244 | запроса отмены. Этот токен означает, что отмена никогда не может произойти. | |
|
|
245 | ||
|
|
246 | Данный токен рекомендуется использовать как значение по-умолчанию для | |
|
|
247 | параметров, принимающих токен отмены. | |
|
|
248 | ||
|
|
249 | ```ts | |
|
|
250 | ||
|
|
251 | async function load(url: string, ct: ICancellation = Cancellation.none) { | |
|
|
252 | ct.throwIfRequested(); | |
