我正在尝试使用POST请求在Google日历中创建一个新事件,但我总是收到400错误。
到目前为止,我有这个:
String url = "https://www.googleapis.com/calendar/v3/calendars/"+ calendarID + "/events?access_token=" + token;
String data = "{\n-\"end\":{\n\"dateTime\": \"" + day + "T" + end +":00.000Z\"\n},\n" +
"-\"start\": {\n \"dateTime\": \"" + day + "T" + begin + ":00.000Z\"\n},\n" +
"\"description\": \"" + description + "\",\n" +
"\"location\": \"" + location + "\",\n" +
"\"summary\": \"" + title +"\"\n}";
System.out.println(data);
URL u = new URL(url);
HttpURLConnection connection = (HttpURLConnection) u.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false);
connection.setRequestMethod("POST");
String a = connection.getRequestMethod();
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("Accept-Charset", "utf-8");
connection.setRequestProperty("Authorization", "OAuth" + token);
connection.setUseCaches(false);
DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
wr.writeBytes(data);
wr.flush();
// Get the response
BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
System.out.println(line);
}
wr.close();
rd.close();
但是,当我创建BufferedReader读取响应时,出现了400错误。怎么了?
提前致谢!
最佳答案
您是否尝试过使用Google APIs Client Library for Java?它将使这样的操作更加简单。配置客户端库并创建服务对象后,进行API调用相对容易。本示例创建一个事件并将其插入日历:
Event event = new Event();
event.setSummary("Appointment");
event.setLocation("Somewhere");
ArrayList<EventAttendee> attendees = new ArrayList<EventAttendee>();
attendees.add(new EventAttendee().setEmail("attendeeEmail"));
// ...
event.setAttendees(attendees);
Date startDate = new Date();
Date endDate = new Date(startDate.getTime() + 3600000);
DateTime start = new DateTime(startDate, TimeZone.getTimeZone("UTC"));
event.setStart(new EventDateTime().setDateTime(start));
DateTime end = new DateTime(endDate, TimeZone.getTimeZone("UTC"));
event.setEnd(new EventDateTime().setDateTime(end));
Event createdEvent = service.events().insert("primary", event).execute();
System.out.println(createdEvent.getId());
假定您已创建here概述的服务对象。
