在 iOS 中发送带有“正文请求”的 NSMutableURLRequest 请求

Question

我目前正在使用 Google 日历 API 并允许用户与参加者进行 post 活动，但是现在我应该发送一个 POST 方法其中包括 "Request Body".

这是我应该发送的请求：

https://www.googleapis.com/calendar/v3/calendars/<MyCalendorID>/events/<MyEventID>

Request Body :

{
 "end": {
  "date": "2015-05-19"
 },
 "start": {
  "date": "2015-05-20"
 },
 "attendees": [
  {
   "email": "nai.bhavesh782@gmail.com"
  }
 ]
}

我肯定我在 [request setHTTPBody] 中做错了什么，但这是我唯一能想到的事情。

请帮忙
