NSURLSession參數不被識別

Question

我試圖使用NSURLSession進行HTTPRequest。當我設置的完整URL請求返回正確的數據，但使用參數時（NSJSONSerialization.dataWithJSONObject - >HTTPBody我得到這個錯誤

error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." 

是有什麼即時通訊做錯了

let json = ["api_key": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"] 
    do { 

     let jsonData = try NSJSONSerialization.dataWithJSONObject(json, options: .PrettyPrinted) 

     let url = NSURL(string: "https://api.themoviedb.org/3/discover/movie")! 
     let request = NSMutableURLRequest(URL: url) 
     request.HTTPBody = jsonData 
     request.HTTPMethod = "GET" 
     request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type") 


     let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data, response, error in 
      if error != nil{ 
       print("Error -> \(error)") 
       return 
      } 
      do { 
       let result = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? [String:AnyObject] 

       print("Result -> \(result)") 

      } catch { 
       print("Error -> \(error)") 
      } 
     } 

     task.resume() 


    } catch { 
     print(error) 
    } 
} 

這是什麼？不是重複的！在問這個問題之前，我看了建議的答案（他們都沒有工作）

在你的情況下，可以通過更改request.HTTPMethod = "GET"request.HTTPMethod = "POST"

你不應該發送HTTP正文獲取請求，與你應該改變列舉HTTPMethod到post

注意身體發送數據：請檢查該API方法支持POST請求，如果它不支持後你不能與HTTP主體/後使用它，按照Doc我只能找「得到」爲​​請求可以是這樣的：

let url = NSURL(string: "http://api.themoviedb.org/3/discover/movie?api_key=YOUR_API_KEY")! 
let request = NSMutableURLRequest(URL: url) 
request.addValue("application/json", forHTTPHeaderField: "Accept") 

let session = NSURLSession.sharedSession() 
let task = session.dataTaskWithRequest(request) { data, response, error in 
    if let response = response, data = data { 
     print(response) 
     print(String(data: data, encoding: NSUTF8StringEncoding)) 
    } else { 
     print(error) 
    } 
} 

task.resume()
