如何解决创建事件时，Google Calendar API v3始终返回BadRequest 答案：修复：参考文献：

我创建了共享日历，并希望向日历中添加事件。

我创建了一个项目并设置了服务帐户xxx@xxx.iam.gserviceaccount.com。

然后，我以所有者的身份将日历共享到服务帐户。

然后我注意到

服务帐户必须手动添加共享日历

如此处所述 https://stackoverflow.com/a/62232361/298430和https://issuetracker.google.com/issues/148804709

所以我写了一个代码：

 @Test
  fun addCalendarToServiceAccount() {

    val calList1: CalendarList = calendar.calendarList().list().execute()
    logger.info("calList1 = {}",calList1)

    val inserted = calendar.calendarList().insert(CalendarListEntry().setId(calendarId)).execute()
    logger.info("inserted = {}",inserted)

    val calList2: CalendarList = calendar.calendarList().list().execute()
    logger.info("calList2 = {}",calList2)
  }

它完美地工作。初次打电话时，我看到calList1为空，并且calList2包含某些内容。

然后我将一个事件手动插入日历（使用Google日历WEB UI），我想检查是否可以检索该事件：

@Test
  fun listEvents() {
    val events: Events = calendar.events().list(calendarId).execute()
    logger.info("events = {}",events)
    events.items.forEachIndexed { index,e ->
      logger.info("Event [index = {}],event = {}",index,e)
    }
  }

它也可以。

{
   "accessRole":"owner","defaultReminders":[

   ],"etag":"\"xxx\"","items":[
      {
         "created":"2020-08-17T17:51:21.000Z","creator":{
            "email":"xxx@gmail.com"
         },"end":{
            "date":"2020-08-20"
         },"htmlLink":"https://www.google.com/calendar/event?eid=xxx","iCalUID":"xxx@google.com","id":"xxx","kind":"calendar#event","organizer":{
            "displayName":"xxx","email":"xxx@group.calendar.google.com","self":true
         },"reminders":{
            "useDefault":false
         },"sequence":0,"start":{
            "date":"2020-08-19"
         },"status":"confirmed","summary":"xxx  test1","transparency":"transparent","updated":"2020-08-18T01:07:54.441Z"
      }
   ],"kind":"calendar#events","nextSyncToken":"xxx","summary":"xxx","timeZone":"Asia/Taipei","updated":"2020-08-18T01:07:54.688Z"
}

然后我要以编程方式插入一些内容，例如API示例所示：

@Test
  fun testInsertEvent() {
    val now = LocalDateTime.now().withSecond(0).withNano(0)
    val zoneId = ZoneId.of("Asia/Taipei")
    val fromDate = Date.from(now.atZone(zoneId).toInstant())
    val endDate = Date.from(now.plusMinutes(60).atZone(zoneId).toInstant())

    val event = Event()
      .setSummary("Google I/O 2015")
      .setLocation("800 Howard St.,San Francisco,CA 94103")
      .setDescription("A chance to hear more about Google's developer products.")
      .setStart(EventDateTime().setDate(DateTime(fromDate,TimeZone.getTimeZone(zoneId))))
      .setEnd(EventDateTime().setDate(DateTime(endDate,TimeZone.getTimeZone(zoneId))))

    logger.info("before insert event : {}",event)

    val eventResult: Event = calendar.events().insert(calendarId,event).execute()
    logger.info("eventResult = {}",eventResult)
  }

我可以看到客户端真正地POST到google'e端点：

身体是：

{
   "description":"A chance to hear more about Google's developer products.","end":{
      "date":"2020-08-18T11:32:00.000+08:00"
   },"location":"800 Howard St.,CA 94103","start":{
      "date":"2020-08-18T10:32:00.000+08:00"
   },"summary":"Google I/O 2015"
}

但是google只是回答了400 BadRequest，没有任何进一步的描述：

 }
}

我正在使用相同的 calendar 实例，可以成功addCalendarToServiceAccount()（作为owner）和listEvents()。但是插入事件时出了什么问题？我有什么想念吗？

其他字段的初始化如下：

  @Value("\${google.calendar.id}")
  private lateinit var calendarId: String

  @Value("\${google.calendar.apiKey}")
  private lateinit var apiKey : String

  private val httpTransport: HttpTransport by lazy {
    GoogleNetHttpTransport.newTrustedTransport()
  }

  private val jacksonFactory: JsonFactory by lazy {
    JacksonFactory.getDefaultInstance()
  }

  private val saCredentials: GoogleCredentials by lazy {
    javaClass.getResourceAsStream("/chancer-d1de03c4c25a.json").use { iStream ->
      ServiceAccountCredentials.fromStream(iStream)
        .createScoped(listOf(
          "https://www.googleapis.com/auth/cloud-platform",*CalendarScopes.all().toTypedArray()
        ))
    }.apply {
      refreshIfExpired()
    }
  }


  private val requestInitializer: HttpRequestInitializer by lazy {
    HttpCredentialsAdapter(saCredentials)
  }

  private val calendar: Calendar by lazy {
    Calendar.Builder(httpTransport,jacksonFactory,requestInitializer)
      .build()
  }

环境：

    <java.version>1.8</java.version>
    <kotlin.version>1.4.0</kotlin.version>


    <dependency>
      <groupId>com.google.api-client</groupId>

解决方法

答案：

您需要使用start.dateTime和end.dateTime而不是start.date和end.date

修复：

根据documentation：

end.date：如果是全天活动，则格式为“ yyyy-mm-dd”的日期。

end.dateTime：时间，作为组合的日期时间值（根据RFC3339格式化）。除非在 timeZone 中明确指定了时区，否则需要时区偏移量。

start.date：如果是全天活动，则格式为“ yyyy-mm-dd”的日期。

start.dateTime：时间，作为组合的日期时间值（根据RFC3339格式化）。除非在 timeZone 中明确指定了时区，否则需要时区偏移量。

因此，您需要从以下日期和时间设置方法更改

：

EventDateTime().setDate(DateTime(fromDate,TimeZone.getTimeZone(zoneId))))

收件人：

EventDateTime().setDateTime(DateTime(fromDate,TimeZone.getTimeZone(zoneId))))

将请求正文更改为：

{
  "description": "A chance to hear more about Google's developer products.","end": {
      "dateTime": "2020-08-18T11:32:00.000+08:00" // modified
  },"location": "800 Howard St.,San Francisco,CA 94103","start": {
    "dateTime": "2020-08-18T10:32:00.000+08:00" // modified
  },"summary": "Google I/O 2015"
}

您可以查看此方法here的文档。

我希望这对您有帮助！
