Swift2 - Multipart Data send

레퍼런스도 없고 인터넷 참고용 코딩도 지저분하지만 일단 복붙

굉장히 더럽고 참고용이기때문에 필요하면 참고한다.

func generateBoundaryString() -> String

{

    return "Boundary-\(NSUUID().UUIDString)"

}

func imageUploadRaw(image:UIImage){

    

    let request = NSMutableURLRequest(URL: NSURL(string: "https://api.projectoxford.ai/face/v1.0/detect")!)

    request.HTTPMethod = "POST"

    let postString = "entities=true&returnFaceId=true&returnFaceLandmarks=true"

    

    let myData : NSData! = postString.dataUsingEncoding(NSUTF8StringEncoding)

    

    let imageData :NSData = UIImagePNGRepresentation(image)!;

    

    let boundary = "----------SwIfTeRhTtPrEqUeStBoUnDaRy"

    let body = NSMutableData();

    

    let tempData = NSMutableData()

    let fileName = "hello.jpg"

    

    

    let mimeType = "application/octet-stream"

    

    tempData.appendData(myData)

    tempData.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    

    tempData.appendData("Content-Disposition: form-data; name=\"\(fileName)\"; \(imageData)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    

    tempData.appendData("Content-Type: \(mimeType)\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    

    tempData.appendData(imageData)

    

    tempData.appendData("\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    

    

    body.appendData(tempData)

    

    body.appendData("\r\n--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    

    request.setValue("\(body.length)", forHTTPHeaderField: "Content-Length")

    

    request.HTTPBody = body

    

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {

        data, response, error in

        

        if error != nil {

            print("error=\(error)")

            return

        }

        

        let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)

        print("responseString = \(responseString!)")

    }

    task.resume()

    

  }

var image = UIImage(named : "male1.png")

//test()

imageUploadRaw(image!)

아래와 같은 걸로 테스트를 해봐도된다.

func test (){

    let url = NSURL(string: "http://httpbin.org/get")

    

    let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in

        print(NSString(data: data!, encoding: NSUTF8StringEncoding))

    }

    

    task.resume()

}
