이미지 나 서버에 데이터 형식 (이미지 데이터/비디오 데이터)으로 multipart 할 스위프트

Question

안녕 지금

  var request = NSMutableURLRequest(URL: NSURL(string: "http://mypath.com")) 
     var session = NSURLSession.sharedSession() 
     request.HTTPMethod = "POST" 

     var params2 :NSDictionary = ["email":"myemail@gmail.com"] 
     var params :NSDictionary = ["function":"forgotPassword", "parameters":params2] 

     var err: NSError? 
     request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err) 
     request.addValue("application/json", forHTTPHeaderField: "Content-Type") 
     request.addValue("application/json", forHTTPHeaderField: "Accept") 

     var task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in 




      var strData = NSString(data: data, encoding: NSUTF8StringEncoding) 
      let decodedJson = NSJSONSerialization.JSONObjectWithData(data, options: nil, error:nil) as NSDictionary 

      println("Body: \(strData)") 

      //Here I am getting response 

      var err: NSError? 
      var json = NSJSONSerialization.JSONObjectWithData(data, options: .MutableLeaves, error: &err) as? NSDictionary 

      // Did the JSONObjectWithData constructor return an error? If so, log the error to the console 
      if(err != nil) { 
       println(err!.localizedDescription) 
       let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding) 
       println("Error could not parse JSON: '\(jsonStr)'") 
      } 
      else { 
       // The JSONObjectWithData constructor didn't return an error. But, we should still 
       // check and make sure that json has a value using optional binding. 
       if let parseJSON = json { 
        // Okay, the parsedJSON is here, let's get the value for 'success' out of it 
        var success = parseJSON["success"] as? Int 
        println("Succes: \(success)") 
       } 
       else { 
        // Woa, okay the json object was nil, something went worng. Maybe the server isn't running? 
        let jsonStr = NSString(data: data, encoding: NSUTF8StringEncoding) 
        println("Error could not parse JSON: \(jsonStr)") 
       } 
       } 
      }) 

      task.resume() 

아래로 빠른에 NSURLSession를 사용하여 서버에 JSON 데이터를 게시하고의 서버에 게시 (또는 비디오) 키 값 "영상"대물 CI에서 USER_ID = 15 about_video_thumb = "myImagejpg"

같은 다른 파라미터들과 함께 아래

-(void)upLoadThumb{ 


    NSMutableURLRequest *request= [[NSMutableURLRequest alloc] init]; 
    [request setURL:[NSURL URLWithString:@"http://mypath.com/uplaodpic"]]; 
    [request setHTTPMethod:@"POST"]; 


    //Setting content type - multipart/form-data 
    NSString *boundary = @"---------------------------14737809831466499882746641449"; 
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 
    NSMutableData *postbody = [NSMutableData data]; 
    [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 





    // This is one field user_id 

     [postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"user_id\"\r\n\r\n%@", @"15"] dataUsingEncoding:NSUTF8StringEncoding]]; 
     [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 



     [postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"about_video_thumb\"; filename=\"%@\"\r\n", @"myImage.jpg"] dataUsingEncoding:NSUTF8StringEncoding]]; 

    //Appending NSDATA 

     [postbody appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    [postbody appendData:[NSData dataWithData:appDelegate.userVdoImageData]]; 
    [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 


    [request setHTTPBody:postbody]; 
    conn = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 
    if (conn) { 
     webData = [NSMutableData data]; 
     } 
    } 

같은 이미지 uplaoding 오전 어떻게 신속하게 NSURLSession 또는 NSURLConnection을 사용하여이 작업을 수행 할 수 있습니까? 미리 감사드립니다.

json body에서 이미지를 업로드하려면 인코딩해야합니다. 당신이

let data = UIImageJPEGRepresentation(image, 0.5) 
let encodedImage = data.base64EncodedStringWithOptions(.allZeros) 

image 지금이 base64로 문자열로 인코딩 된 UIImage 인스턴스가 있다고 가정하자. 우리는 json body에서 사용할 수 있습니다.

let parameters = ["image": encodedImage, "otherParam": "otherValue"] 

let session = NSURLSession.sharedSession() 
let request = NSMutableURLRequest(URL: NSURL(string: "YOUR_URL")!) 
request.setValue("application/json", forHTTPHeaderField: "Content-Type") 
request.HTTPMethod = "POST" 

var error: NSError? 
request.HTTPBody = NSJSONSerialization.dataWithJSONObject(parameters, options: .allZeros, error: &error) 

if let error = error { 
    println("\(error.localizedDescription)") 
} 

let dataTask = session.dataTaskWithRequest(request) { data, response, error in 
    // Handle response 
} 

dataTask.resume()
