Alamofireを使用したパラメーター付きファイルのアップロード

Alamofireを使用してファイルをアップロードしようとしています。ファイル(NSUrl)を使用している場合、アップロードは正常に機能しますが、NSDataオプションの使用方法を理解できないようです。

これは私がテストとして持っているものです:

 var url:NSURL = NSURL.URLWithString("http://localhost:8080/bike.jpeg")

 var err: NSError?
 var imageData :NSData = NSData.dataWithContentsOfURL(url,options: NSDataReadingOptions.DataReadingMappedIfSafe, error: &err)

 Alamofire.upload(.POST, "http://localhost:8080/rest/service/upload/test.png", imageData)
        .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
            println(totalBytesWritten)
        }
        .responseJSON { (request, response, JSON, error) in
            println(request)
            println(response)
           println(JSON)
 }

ステータスコード415が表示されますか?

また、アップロードで追加のパラメータを送信するにはどうすればよいですか?

ありがとう

正しいContent-Typeを設定していませんでした:

var manager = Manager.sharedInstance
manager.session.configuration.HTTPAdditionalHeaders = ["Content-Type": "application/octet-stream"]


let imageData: NSMutableData = NSMutableData.dataWithData(UIImageJPEGRepresentation(imageTest.image, 30));

Alamofire.upload(.POST, "http://localhost:8080/rest/service/upload?attachmentName=file.jpg",  imageData)
        .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
            println(totalBytesWritten)
        }
        .responseString { (request, response, JSON, error) in
            println(request)
            println(response)
            println(JSON)
}

それでも、アップロードとともに追加のパラメータを送信する方法はわかりません。

これは、ターゲットのアップロードURL、パラメーター、およびimageDataを必要とし、Alamofire.uploadがパラメーター付きの画像をアップロードするために必要なURLRequestConvertibleおよびNSDataを返す単純な関数です。

// this function creates the required URLRequestConvertible and NSData we need to use Alamofire.upload
func urlRequestWithComponents(urlString:String, parameters:Dictionary<String, String>, imageData:NSData) -> (URLRequestConvertible, NSData) {

    // create url request to send
    var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
    mutableURLRequest.HTTPMethod = Alamofire.Method.POST.rawValue
    let boundaryConstant = "myRandomBoundary12345";
    let contentType = "multipart/form-data;boundary="+boundaryConstant
    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")



    // create upload data to send
    let uploadData = NSMutableData()

    // add image
    uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"file.png\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData(imageData)

    // add parameters
    for (key, value) in parameters {
        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
    }
    uploadData.appendData("\r\n--\(boundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)



    // return URLRequestConvertible and NSData
    return (Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
}    

使用方法の例を以下に示します(CREATE AND SEND REQUESTを参照)。

// init paramters Dictionary
var parameters = [
    "task": "task",
    "variable1": "var"
]

// add addtionial parameters
parameters["userId"] = "27"
parameters["body"] = "This is the body text."

// example image data
let image = UIImage(named: "177143.jpg")
let imageData = UIImagePNGRepresentation(image)



// CREATE AND SEND REQUEST ----------

let urlRequest = urlRequestWithComponents("http://example.com/uploadText/", parameters: parameters, imageData: imageData)

Alamofire.upload(urlRequest.0, urlRequest.1)
    .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
        println("\(totalBytesWritten) / \(totalBytesExpectedToWrite)")
    }
    .responseJSON { (request, response, JSON, error) in
        println("REQUEST \(request)")
        println("RESPONSE \(response)")
        println("JSON \(JSON)")
        println("ERROR \(error)")
}    

ターゲットURLのphpファイルが必要な場合(同じディレクトリに「アップロード」フォルダーがある場合):

// get picture variables
$file       = $_FILES['file']['tmp_name'];
$fileName   = $_FILES['file']['name'];
$fileType   = $_FILES['file']['type'];

// check extension
$allowedExts = array("jpg", "jpeg", "png");
$rootName = reset(explode(".", $fileName));
$extension = end(explode(".", $fileName));

// create new file name
$time = time();
$newName = $rootName.$time.'.'.$extension;

// temporarily save file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "uploads/".$newName );
if ($moved) $path = "uploads/".$newName;

$body = $_POST['body'];
$userId = $_POST['userId'];


$time = time();
if ($moved) {
    $fullUrl = "http://antiblank.com/testPhotoUpload/".$path;
    $arrayToSend = array('status'=>'success','time'=>$time,'body'=>$body,'userId'=>$userId, "imageURL"=>$fullUrl);
} else {
    $arrayToSend = array('status'=>'FAILED','time'=>$time,'body'=>$body,'userId'=>$userId);
}

header('Content-Type:application/json');
echo json_encode($arrayToSend);

マルチパートアップロードは、Alamofireの次のリリース(1.3.0)に含まれる予定です。それまでの間、このスレッドの情報を使用して、ファイルのアップロードを簡素化し、1つ以上のファイルとともにリクエストに追加のパラメーター(通常の「入力」)を含めるクラスを作成しました。ファイルが特定のタイプまたはルーターの使用であると仮定することなく。

FileUploader.Swift:

import Foundation
import Alamofire

private struct FileUploadInfo {
  var name:String
  var mimeType:String
  var fileName:String
  var url:NSURL?
  var data:NSData?

  init( name: String, withFileURL url: NSURL, withMimeType mimeType: String? = nil ) {
    self.name = name
    self.url = url
    self.fileName = name
    self.mimeType = "application/octet-stream"
    if mimeType != nil {
      self.mimeType = mimeType!
    }
    if let _name = url.lastPathComponent {
      fileName = _name
    }
    if mimeType == nil, let _extension = url.pathExtension {
      switch _extension.lowercaseString {

      case "jpeg", "jpg":
        self.mimeType = "image/jpeg"

      case "png":
        self.mimeType = "image/png"

      default:
        self.mimeType = "application/octet-stream"
      }
    }
  }

  init( name: String, withData data: NSData, withMimeType mimeType: String ) {
    self.name = name
    self.data = data
    self.fileName = name
    self.mimeType = mimeType
  }
}

class FileUploader {

  private var parameters = [String:String]()
  private var files = [FileUploadInfo]()
  private var headers = [String:String]()

  func setValue( value: String, forParameter parameter: String ) {
    parameters[parameter] = value
  }

  func setValue( value: String, forHeader header: String ) {
    headers[header] = value
  }

  func addParametersFrom( #map: [String:String] ) {
    for (key,value) in map {
      parameters[key] = value
    }
  }

  func addHeadersFrom( #map: [String:String] ) {
    for (key,value) in map {
      headers[key] = value
    }
  }

  func addFileURL( url: NSURL, withName name: String, withMimeType mimeType:String? = nil ) {
    files.append( FileUploadInfo( name: name, withFileURL: url, withMimeType: mimeType ) )
  }

  func addFileData( data: NSData, withName name: String, withMimeType mimeType:String = "application/octet-stream" ) {
    files.append( FileUploadInfo( name: name, withData: data, withMimeType: mimeType ) )
  }

  func uploadFile( request sourceRequest: NSURLRequest ) -> Request? {
    var request = sourceRequest.mutableCopy() as! NSMutableURLRequest
    let boundary = "FileUploader-boundary-\(arc4random())-\(arc4random())"
    request.setValue( "multipart/form-data;boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
    let data = NSMutableData()

    for (name, value) in headers {
      request.setValue(value, forHTTPHeaderField: name)
    }

    // Amazon S3 (probably others) wont take parameters after files, so we put them first        
    for (key, value) in parameters {
      data.appendData("\r\n--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      data.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
    }

    for fileUploadInfo in files {
      data.appendData( "\r\n--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)! )
      data.appendData( "Content-Disposition: form-data; name=\"\(fileUploadInfo.name)\"; filename=\"\(fileUploadInfo.fileName)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      data.appendData( "Content-Type: \(fileUploadInfo.mimeType)\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      if fileUploadInfo.data != nil {
        data.appendData( fileUploadInfo.data! )
      }
      else if fileUploadInfo.url != nil, let fileData = NSData(contentsOfURL: fileUploadInfo.url!) {
        data.appendData( fileData )
      }
      else { // ToDo: report error
        return nil
      }
    }

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

    return Alamofire.upload( request, data )
  }

}

次のように使用されます。

// This example uploads a file called example.png found in the app resources

let fileURL = NSBundle.mainBundle().URLForResource("example", withExtension: "png")
let fileUploader = FileUploader()
// we can add multiple files
// this would be equivalent to: <input type="file" name="myFile"/>
fileUploader.addFileURL(fileURL!, withName: "myFile")
// we can add NSData objects directly
let data = UIImage(named: "sample")
fileUploader.addFileData( UIImageJPEGRepresentation(data,0.8), withName: "mySecondFile", withMimeType: "image/jpeg" )
// we can also add multiple aditional parameters
// this would be equivalent to: <input type="hidden" name="folderName" value="sample"/>
fileUploader.setValue( "sample", forParameter: "folderName" )
// put your server URL here
var request = NSMutableURLRequest( URL: NSURL(string: "http://myserver.com/uploadFile" )! )
request.HTTPMethod = "POST"
fileUploader.uploadFile(request: request)

@antiblankの答えのコードは、私にとってはうまくいきませんでした。私はいくつかの変更を加えましたが、現在機能しています:

func urlRequestWithComponents(urlString:String, parameters:NSDictionary) -> (URLRequestConvertible, NSData) {

    // create url request to send
    var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
    mutableURLRequest.HTTPMethod = Alamofire.Method.POST.rawValue
    //let boundaryConstant = "myRandomBoundary12345"
    let boundaryConstant = "NET-POST-boundary-\(arc4random())-\(arc4random())"
    let contentType = "multipart/form-data;boundary="+boundaryConstant
    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")


    // create upload data to send
    let uploadData = NSMutableData()

    // add parameters
    for (key, value) in parameters {

        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

        if value is NetData {
            // add image
            var postData = value as NetData


            //uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"; filename=\"\(postData.filename)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

            // append content disposition
            var filenameClause = " filename=\"\(postData.filename)\""
            let contentDispositionString = "Content-Disposition: form-data; name=\"\(key)\";\(filenameClause)\r\n"
            let contentDispositionData = contentDispositionString.dataUsingEncoding(NSUTF8StringEncoding)
            uploadData.appendData(contentDispositionData!)


            // append content type
            //uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!) // mark this. 
            let contentTypeString = "Content-Type: \(postData.mimeType.getString())\r\n\r\n"
            let contentTypeData = contentTypeString.dataUsingEncoding(NSUTF8StringEncoding)
            uploadData.appendData(contentTypeData!)
            uploadData.appendData(postData.data)

        }else{
            uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
        }
    }
    uploadData.appendData("\r\n--\(boundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)



    // return URLRequestConvertible and NSData
    return (Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
}

つかいます:

let docDir:AnyObject = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
let imagePath = docDir + "/myPic.jpg"

var imageData = NSData(contentsOfFile: imagePath, options: NSDataReadingOptions.DataReadingMappedIfSafe, error: nil)
var parameters = [
            "pic"           :NetData(nsData: imageData!, filename: "customName.jpg"),
            "otherParm"     :"Value"
        ]


    let urlRequest = self.urlRequestWithComponents("http://www.example.com/upload.php", parameters: parameters)

https://github.com/nghialv/Net/blob/master/Net/NetData.Swift からのNetData

upload.phpコード:

<?php
// In PHP versions earlier than 4.1.0, $HTTP_POST_FILES should be used instead
// of $_FILES.

$uploaddir = 'uploads/';
// PS: custom filed name : pic
$uploadfile = $uploaddir . basename($_FILES['pic']['name']);

if (move_uploaded_file($_FILES['pic']['tmp_name'], $uploadfile)) {
   $array = array ("code" => "1", "message" => "successfully");  
} else {
   $array = array ("code" => "0", "message" => "Possible file upload attack!".$_FILES['pic']['name']); 
}

echo json_encode ( $array );

マルチパートリクエストを手動で作成する方法をアドバイスする他の回答がありますが、AFNetworkingに固執することもできます。 Objective-Cで記述されていても、Swiftプロジェクトで使用できます(同じプロジェクト内の SwiftとObjective-C を参照)。とにかく、AFNetworkingを使用してマルチパートリクエストを送信するSwiftコードは次のとおりです。

let data = UIImagePNGRepresentation(image)

let manager = AFHTTPSessionManager()

manager.POST(uploadURLString, parameters: nil, constructingBodyWithBlock: { formData in
    formData.appendPartWithFileData(data, name: "image", fileName: "test.png", mimeType: "image/png")
}, success: { operation, responseObject in
    println(responseObject)
}) { operation, error in
    println(error)
}

Xcodeには、このid<AFMultipartFormData>パラメーター、formDataの認識に問題があるため、appendPartWithFileDataメソッドまたはそのパラメーターの一般的なエディターコード補完をお楽しみいただけませんが、コンパイルして実行すると正常に機能します。

        var request = route.URLRequest.mutableCopy() as NSMutableURLRequest
        let boundary = "NET-POST-boundary-\(arc4random())-\(arc4random())"
        request.setValue("multipart/form-data;boundary="+boundary,
                         forHTTPHeaderField: "Content-Type")

        let parameters = NSMutableData()
        for s in ["\r\n--\(boundary)\r\n",

使用法

let rep = (asset as ALAsset).defaultRepresentation()
let ref = rep.fullResolutionImage().takeUnretainedValue()
Photo.upload(UIImage(CGImage: ref)!, filename: rep.filename())
    .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
        println(totalBytesWritten)
    }
    .responseJSON { (request, response, JSON, error) in
        println(JSON)
    }

以下はSwiftとPHPコードです

Swiftコード-> Apple Swiftバージョン3.0.1(swiftlang-800.0.58.6 clang-800.0.42.1)ターゲット:x86_64-Apple-macosx10.9

   class  func upload(jsonObject: AnyObject , files : Array<Any>? = nil  , completionHandler :  CompletionBlock? = nil ,failureHandler : FailureBlock? = nil )
{

    Alamofire.upload(multipartFormData:
        { (multipartFormData) in

            if let  filesO = files
            {
                for i in (filesO.enumerated())
                {
                    let image = UIImage(named: "\(i.element)")

                    let data = UIImageJPEGRepresentation(image!, 1)!

                    multipartFormData.append(data, withName: "imgFiles[]" , fileName: "\( NSUUID().uuidString).jpeg" , mimeType: "image/jpeg")
                  // imgFiles[] give array in Php Side
                  // imgFiles   will give string in PHP String


                }

            }


            for  (key, value)  in jsonObject as! [String : String]
            {

                 multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)

            }}          
    },
                     to:baseURL)

パラメータとファイルを取得するPHPコード

ここで、パラメータは$ _Requestのハンドルです

ファイルは$ _Fileで処理されます

$ _File data(Array、DictionaryまたはString)の形式はSwift sideのRequestに依存します。ここにコードのこの行を参照してください

multipartFormData.append(data、withName: "imgFiles []"、fileName: "(NSUUID()。uuidString).jpeg"、mimeType: "image/jpeg")

pHP側でwithName: "imgFiles []"は、名前、フォーマット、タイプの配列を提供します

例えば

"name":["06748B86-478E-421B-8470-6262755AC149.jpeg"、 "E70269E9-FB54-4BFD-B807-7E418C81540D.jpeg"]、 "type":["image/jpeg"、 "image/jpeg" ]、 "tmp_name":["/ tmp/phpz3UAPq"、 "/ tmp/phpCAPExG"]、 "error":[0,0]、 "size":[2779495,2067259]}

PHPコード

 if (isset($_FILES['imgFiles']) and strlen($orderId) > 0) {

        foreach ($_FILES['imgFiles']['tmp_name'] as $key => $tmp_name) {

            $file_name = $key . $_FILES['imgFiles']['name'][$key];
            $file_size = $_FILES['imgFiles']['size'][$key];
            $file_tmp = $_FILES['imgFiles']['tmp_name'][$key];
            $file_type = $_FILES['imgFiles']['type'][$key];
 if (is_dir("$desired_dir/" . $file_name) == false) {
                //move_uploaded_file($file_tmp, "user_data/" . $file_name);
                move_uploaded_file($file_tmp, $desired_dir . "/" .
           $file_name);
            } else {         //rename the file if another one exist
                $new_dir = $desired_dir . "/" . $file_name . time();
                rename($file_tmp, $new_dir);
            }
