# 创建、修改、查询及删除日程
> 演示通过企业内部应用调用日程 API 完成日程创建、修改、单个查询和删除的完整接入流程，覆盖应用凭证获取与接口权限添加。
本文档介绍了如何调用日程接口创建日程等流程。首先创建一个企业内部应用，再使用日程提供的API，实现创建日程、修改日程、查询单个日程详情、删除日程流程。
## 预期效果
创建日程后，效果如下图所示：
## 接入流程简介
本文档展示了创建一个企业内部应用，再使用日程提供的API，实现创建日程、修改日程、查询单个日程详情、删除日程流程。
前提条件：完成[应用创建与配置](/zh/open/dingstart/create-application)的流程。
步骤一：获取应用凭证信息，获取应用 Client ID 和 Client Secret。
步骤二：申请接口权限，申请日程相关接口的权限。
步骤三：获取应用访问凭证[获取企业内部应用的accessToken](/zh/open/development/obtain-the-access-token-of-an-internal-app)，调用接口时，通过accessToken鉴权调用者身份。
步骤四：调用服务端日程相关API：
1. 调用服务端API-[创建日程](/zh/open/development/create-schedule)接口，进行创建日程。获取日程`id`。
2. 根据日程`id`，调用服务端API-[修改日程](/zh/open/development/modify-event)接口，进行日程信息修改。
3. 根据日程`id`，调用服务端API-[查询单个日程详情](/zh/open/development/query-details-about-an-event)接口，获取日程详情信息。
4. 根据日程`id`，调用服务端API-[删除日程](/zh/open/development/delete-event)接口，删除创建的日程。
## 前提条件
完成[应用创建与配置](/zh/open/dingstart/create-application)的流程。
## 步骤一：获取应用凭证
1. 选择目标应用，进入应用详情页，单击**基础信息** > **凭证与基础信息**。
2. 获取应用 Client ID 和 Client Secret。
## 步骤二：添加接口权限
单击**开发配置** > **权限管理**，在权限搜索框中分别输入`Calendar.Event.Write`和`Calendar.Event.Read`，并申请权限。
## 步骤三：获取应用访问凭证accessToken
服务端API差异详情参见旧版API VS 新版API。以下接口均使用服务端API接口，SDK下载详情参见服务端SDK下载。
根据步骤一中 的 Client ID 和 Client Secret，获取应用访问凭证[获取企业内部应用的access\_token](/zh/open/development/obtain-orgapp-token)。
```java theme={"theme":{"light":"github-light","dark":"github-dark"}}
public void getAccessToken() throws Exception {
Config config = new Config();
config.protocol = "https";
config.regionId = "central";
com.aliyun.dingtalkoauth2_1_0.Client client = new com.aliyun.dingtalkoauth2_1_0.Client(config);
GetAccessTokenRequest accessTokenRequest = new GetAccessTokenRequest()
.setAppKey("ding*********hgn")
.setAppSecret("9G_O**********xamBkhgGIO");
GetAccessTokenResponse accessToken = client.getAccessToken(accessTokenRequest);
System.out.println(JSON.toJSONString(accessToken.getBody()));
}
```
## 步骤四：调用服务端日程相关API
1. 调用服务端API-[创建日程](/zh/open/development/create-schedule)接口，进行创建日程。获取日程`id`。
```java lines theme={"theme":{"light":"github-light","dark":"github-dark"}}
public void createCalendar() throws Exception {
Config config = new Config();

CreateEventHeaders createEventHeaders = new CreateEventHeaders();
createEventHeaders.xAcsDingtalkAccessToken = "accessToken";
java.util.Map extra = TeaConverter.buildMap(
new TeaPair("noChatNotification", "false"),
new TeaPair("noPushNotification","false")
);
CreateEventRequest.CreateEventRequestOnlineMeetingInfo onlineMeetingInfo = new CreateEventRequest.CreateEventRequestOnlineMeetingInfo()
.setType("dingtalk");

.setStart(start)
.setEnd(end)
.setIsAllDay(true)
.setRecurrence(recurrence)
.setAttendees(java.util.Arrays.asList(
attendees0,
attendees1,
attendees2
))
.setLocation(location)

.setOnlineMeetingInfo(onlineMeetingInfo)
.setExtra(extra);
try {
CreateEventResponse eventWithOptions = client.createEventWithOptions("日程组织人unionId", "primary", createEventRequest, createEventHeaders, new RuntimeOptions());
System.out.println(JSON.toJSONString(eventWithOptions.getBody()));
} catch (TeaException err) {
if (!com.aliyun.teautil.Common.empty(err.code) && !com.aliyun.teautil.Common.empty(err.message)) {
// err 中含有 code 和 message 属性，可帮助开发定位问题
System.out.println(err.code);

// err 中含有 code 和 message 属性，可帮助开发定位问题
System.out.println(err.code);
System.out.println(err.message);
}
}
}
```
2. 根据日程`id`，调用服务端API-[修改日程](/zh/open/development/modify-event)接口，进行日程信息修改。
```java lines theme={"theme":{"light":"github-light","dark":"github-dark"}}
public void updateCalendar() throws Exception {
Config config = new Config();
config.protocol = "https";
config.regionId = "central";
com.aliyun.dingtalkcalendar_1_0.Client client = new com.aliyun.dingtalkcalendar_1_0.Client(config);
PatchEventHeaders patchEventHeaders = new PatchEventHeaders();
patchEventHeaders.xAcsDingtalkAccessToken = "accessToken";
PatchEventRequest.PatchEventRequestReminders reminders0 = new PatchEventRequest.PatchEventRequestReminders()
.setMethod("dingtalk")
.setMinutes(15);
java.util.Map extra = TeaConverter.buildMap(
new TeaPair("noChatNotification", "false"),
new TeaPair("noPushNotification","false")
);
PatchEventRequest.PatchEventRequestLocation location = new PatchEventRequest.PatchEventRequestLocation()
.setDisplayName("room 1-2-3");
PatchEventRequest.PatchEventRequestAttendees attendees0 = new PatchEventRequest.PatchEventRequestAttendees()
.setId("日程参与人unionId")
.setIsOptional(false);
PatchEventRequest.PatchEventRequestRecurrenceRange recurrenceRange = new PatchEventRequest.PatchEventRequestRecurrenceRange()
.setType("numbered")
.setNumberOfOccurrences(1);
PatchEventRequest.PatchEventRequestRecurrencePattern recurrencePattern = new PatchEventRequest.PatchEventRequestRecurrencePattern()

.setRange(recurrenceRange);
PatchEventRequest.PatchEventRequestEnd end = new PatchEventRequest.PatchEventRequestEnd()
.setDate("2022-09-02");
PatchEventRequest.PatchEventRequestStart start = new PatchEventRequest.PatchEventRequestStart()
.setDate("2022-09-02");
PatchEventRequest patchEventRequest = new PatchEventRequest()
.setSummary("0902修改日程内容")
.setId("日程id")
.setDescription("这是一个0902修改的日程")
.setStart(start)
.setEnd(end)
.setIsAllDay(true)
.setRecurrence(recurrence)
.setAttendees(java.util.Arrays.asList(
attendees0
))
.setLocation(location)
.setExtra(extra)
.setReminders(java.util.Arrays.asList(
reminders0
));
try {
PatchEventResponse patchEventResponse = client.patchEventWithOptions("日程组织者unionId", "primary", "日程id", patchEventRequest, patchEventHeaders, new RuntimeOptions());
System.out.println(JSON.toJSONString(patchEventResponse.getBody()));
} catch (TeaException err) {
if (!com.aliyun.teautil.Common.empty(err.code) && !com.aliyun.teautil.Common.empty(err.message)) {
// err 中含有 code 和 message 属性，可帮助开发定位问题
System.out.println(err.code);
System.out.println(err.message);
}
} catch (Exception _err) {
TeaException err = new TeaException(_err.getMessage(), _err);
if (!com.aliyun.teautil.Common.empty(err.code) && !com.aliyun.teautil.Common.empty(err.message)) {
// err 中含有 code 和 message 属性，可帮助开发定位问题
System.out.println(err.code);
System.out.println(err.message);
}
}
}
```
3. 根据日程`id`，调用服务端API-[查询单个日程详情](/zh/open/development/query-details-about-an-event)接口，获取日程详情信息。
```java lines theme={"theme":{"light":"github-light","dark":"github-dark"}}
public void calendarInfo() throws Exception {
Config config = new Config();
config.protocol = "https";
config.regionId = "central";
com.aliyun.dingtalkcalendar_1_0.Client client = new com.aliyun.dingtalkcalendar_1_0.Client(config);
GetEventHeaders getEventHeaders = new GetEventHeaders();
getEventHeaders.xAcsDingtalkAccessToken = "accessToken";
GetEventRequest getEventRequest = new GetEventRequest()
.setMaxAttendees(100L);
try {
GetEventResponse eventWithOptions = client.getEventWithOptions("日程组织者unionId", "primary", "日程id", getEventRequest, getEventHeaders, new RuntimeOptions());
System.out.println(JSON.toJSONString(eventWithOptions.getBody()));
} catch (TeaException err) {
if (!com.aliyun.teautil.Common.empty(err.code) && !com.aliyun.teautil.Common.empty(err.message)) {
// err 中含有 code 和 message 属性，可帮助开发定位问题
System.out.println(err.code);
System.out.println(err.message);
}
} catch (Exception _err) {
TeaException err = new TeaException(_err.getMessage(), _err);
if (!com.aliyun.teautil.Common.empty(err.code) && !com.aliyun.teautil.Common.empty(err.message)) {
// err 中含有 code 和 message 属性，可帮助开发定位问题
System.out.println(err.code);
System.out.println(err.message);
}
}
}
```
4. 根据日程`id`，调用服务端API-[删除日程](/zh/open/development/delete-event)接口，删除创建的日程。
```java lines theme={"theme":{"light":"github-light","dark":"github-dark"}}
public void deleteCalendar() throws Exception {
Config config = new Config();
config.protocol = "https";
config.regionId = "central";
com.aliyun.dingtalkcalendar_1_0.Client client = new com.aliyun.dingtalkcalendar_1_0.Client(config);
DeleteEventHeaders deleteEventHeaders = new DeleteEventHeaders();
deleteEventHeaders.xAcsDingtalkAccessToken = "accessToken";
try {
client.deleteEventWithOptions("日程组织者unionId", "primary", "日程id", deleteEventHeaders, new RuntimeOptions());
} catch (TeaException err) {
if (!com.aliyun.teautil.Common.empty(err.code) && !com.aliyun.teautil.Common.empty(err.message)) {
// err 中含有 code 和 message 属性，可帮助开发定位问题
System.out.println(err.code);
System.out.println(err.message);
}
} catch (Exception _err) {
TeaException err = new TeaException(_err.getMessage(), _err);
if (!com.aliyun.teautil.Common.empty(err.code) && !com.aliyun.teautil.Common.empty(err.message)) {
// err 中含有 code 和 message 属性，可帮助开发定位问题
System.out.println(err.code);
System.out.println(err.message);
}
}
}
```
支持以下2种删除场景：
* 当组织者删除日程时（Path参数中的userId参数使用组织者uninoId），所有参与者会收到日程取消通知，同时日程将从所有参与者的日历中删除。
* 当参与者删除日程时（Path参数中的userId参数使用参与者uninoId），仅将日程从自己的日历中删除，其他日程参与者不受影响。
