删除事件时未找到Google.Apis.Requests.RequestError

Question

我有以下方法删除日历中的事件：

public async Task<string> DeleteEventInCalendarAsync(TokenResponse token, string googleUserId, string calendarId, string eventId)
{
string result = null;
try
{
if (_calService == null)
{
_calService = GetCalService(token, googleUserId);
}
// Check if event exist
var eventResource = new EventsResource(_calService);
var erListRequest = eventResource.List(calendarId);
var eventsResponse = await erListRequest.ExecuteAsync().ConfigureAwait(false);
var existingEvent = eventsResponse.Items.FirstOrDefault(e => e.Id == eventId);
if (existingEvent != null)
{
var deleteRequest = new EventsResource.DeleteRequest(_calService, calendarId, eventId);
result = await deleteRequest.ExecuteAsync().ConfigureAwait(false);
}
}
catch (Exception exc)
{
result = null;
_logService.LogException(exc);
}
return result;
}

我收到如下错误 -

Google.GoogleApiException Google.Apis.Requests.RequestError Not Found [404] Errors [ Message[Not Found] Location[ - ] Reason[notFound] Domain[global] ]

你能帮我理解为什么会出现这个错误吗？或者我在哪里可以找到有关这些错误的详细信息？

您收到的错误是由于您传递的事件 id 不存在或您以错误的方式传递它。按照 .Net 快速入门，我制作了一个简单的代码示例，介绍如何将事件的 id 从类事件传递到Delete(字符串 calendarId，字符串事件 Id(方法

。

namespace CalendarQuickstart
{
class Program
{
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/calendar-dotnet-quickstart.json
static string[] Scopes = { CalendarService.Scope.Calendar };
static string ApplicationName = "Google Calendar API .NET Quickstart";
static void Main(string[] args)
{
UserCredential credential;
using (var stream =
new FileStream("credentials.json", FileMode.Open, FileAccess.Read))
{
// The file token.json stores the user's access and refresh tokens, and is created
// automatically when the authorization flow completes for the first time.
string credPath = "token.json";
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
Scopes,
"user",
CancellationToken.None,
new FileDataStore(credPath, true)).Result;
Console.WriteLine("Credential file saved to: " + credPath);
}
// Create Google Calendar API service.
var service = new CalendarService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = ApplicationName,
});
// Define  request.
EventsResource.ListRequest request = service.Events.List("primary");
// List events.
Events events = request.Execute();
Event existingEvent = events.Items.FirstOrDefault(e => e.Id == "your event id you want to get");
Console.WriteLine("Upcoming events:");
if (existingEvent != null)
{
Console.WriteLine("{0} {1}", existingEvent.Summary, existingEvent.Id);
string deleteEvent = service.Events.Delete("primary",  existingEvent.Id).Execute();
}
else
{
Console.WriteLine("No upcoming events found.");
}
Console.Read();
}
}
}

通知

我以同步语法方式制作了此示例，以便在控制台中进行测试。测试它并查看其工作原理后，您可以根据代码对其进行调整。请记住，使您的您传递正确的ID。
