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。
@antiblankと@VincentYanの回答に基づく短いバージョン。
クラス
class Photo {
class func upload(image: UIImage, filename: String) -> Request {
let route = Router.CreatePhoto()
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",
"Content-Disposition: form-data; name=\"photos[photo]\";" +
" filename=\"\(filename)\"\r\n",
"Content-Type: image/png\r\n\r\n"] {
parameters.appendData(s.dataUsingEncoding(NSUTF8StringEncoding)!)
}
parameters.appendData(UIImageJPEGRepresentation(image, 1))
parameters.appendData("\r\n--\(boundary)--\r\n"
.dataUsingEncoding(NSUTF8StringEncoding)!)
return Alamofire.upload(request, parameters)
}
}
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)
}
リクエストにコンテンツタイプがないため、415になります。以下は、Swift 2およびAlamoFireでの画像アップロードの合計結果です。
import UIKit
import Alamofire
class ViewController: UIViewController {
@IBOutlet var imageView: UIImageView!
@IBOutlet var btnUpload: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
}
func successDataHandler(responseData:String){
print ("IMAGE UPLOAD SUCCESSFUL !!!")
}
func failureDataHandler(errorData:String){
print (" !!! IMAGE UPLOAD FAILURE !!! ")
}
@IBAction func actionUpload(sender: AnyObject) {
let URL = "http://m8coreapibeta.azurewebsites.net/api/cards/SaveImages"
let postDataProlife:[String:AnyObject] = ["CardId":(dataCardDetail?.userId)!,"ImageType":1,"ImageData":imageView.image!]
uplaodImageData(URL, postData: postDataProlife, successHandler: successDataHandler, failureHandler: failureDataHandler)
}
func uplaodImageData(RequestURL: String,postData:[String:AnyObject]?,successHandler: (String) -> (),failureHandler: (String) -> ()) -> () {
let headerData:[String : String] = ["Content-Type":"application/json"]
Alamofire.request(.POST,RequestURL, parameters: postData, encoding: .URLEncodedInURL, headers: headerData).responseString{ response in
switch response.result {
case .Success:
print(response.response?.statusCode)
successHandler(response.result.value!)
case .Failure(let error):
failureHandler("\(error)")
}
}
}
}
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);
}
