Uploading file with parameters using Alamofire
提问by user3432352
I am attempting to upload a file using Alamofire. The upload works fine when using a File (NSUrl), however, I cant seem to figure out how to use the NSDataoption?
我正在尝试使用Alamofire. 使用 File ( NSUrl)时上传工作正常，但是，我似乎无法弄清楚如何使用该NSData选项？
This is what I have as a test:
这是我的测试：
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)
}
I am getting a status code 415?
我收到状态码 415？
Also, how can I send across additional params in the upload?
另外，如何在上传中发送其他参数？
Thanks
谢谢
EDIT
编辑
I wasn't setting the correct Content-Type:
我没有设置正确的内容类型：
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)
}
Still cant figure out how to send additional parameters along with the upload.
仍然无法弄清楚如何在上传的同时发送附加参数。

Here is a simple function that requires the target upload url, parameters, and imageData and returns the URLRequestConvertible and NSData that Alamofire.upload requires to upload an image with parameters.
这是一个简单的函数，它需要目标上传 url、参数和 imageData，并返回 Alamofire.upload 上传带有参数的图像所需的 URLRequestConvertible 和 NSData。
// 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)
}
Here's an example of how to use it (see CREATE AND SEND REQUEST):
以下是如何使用它的示例（请参阅创建并发送请求）：
// 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)")
}
And if you need the php file for the target url (with an 'uploads' folder in the same directory):
如果您需要目标 url 的 php 文件（在同一目录中有一个“上传”文件夹）：
// 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);

Multipart upload is scheduled to be included with the next (1.3.0) release of Alamofire. In the meantime, using the information in this thread, I've made a class that simplifies uploading files and including additional parameters (regular "inputs") in the request along with one or more files. Without assuming that files are of a particular type or the use of Routers.
分段上传计划包含在 Alamofire 的下一个 (1.3.0) 版本中。同时，使用此线程中的信息，我创建了一个类，该类可简化上传文件并在请求中包含一个或多个文件的附加参数（常规“输入”）。不假设文件属于特定类型或使用路由器。
FileUploader.swift:
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 )
}
}
It would be used like this:
它将像这样使用：
// 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)

While there are other answers that advise how to manually construct multipart requests, you might just want to stick with AFNetworking. Even though it's written in Objective-C, you can still use it in your Swift projects (see Swift and Objective-C in the Same Project). Anyway, the Swift code to submit a multipart request using AFNetworking is as follows:
虽然还有其他答案建议如何手动构建多部分请求，但您可能只想坚持使用 AFNetworking。即使它是用 Objective-C 编写的，你仍然可以在你的 Swift 项目中使用它（参见Swift 和 Objective-C in the Same Project）。无论如何，使用 AFNetworking 提交多部分请求的 Swift 代码如下：
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 annoying has problems recognizing this id<AFMultipartFormData>parameter, formData, so you don't enjoy the typical editor code completion of the appendPartWithFileDatamethod or its parameters, but when you compile it, and run it, it works fine.
Xcode烦人在识别这个id<AFMultipartFormData>参数时有问题formData，所以你不喜欢典型的编辑器代码完成appendPartWithFileData方法或其参数，但是当你编译它并运行它时，它工作正常。

获取参数和文件的 PHP 代码
Here Parameters are Handle in $_Request
这里的参数是 $_Request 中的句柄
And Files are handle in $_File
文件在 $_File 中处理
Format in $_File data(Array , Dictionary or String ) will depend on Request in swift side , Here See this line in code
$_File 数据（数组、字典或字符串）中的格式将取决于 swift 端的请求，请参见代码中的这一行
multipartFormData.append(data, withName: "imgFiles[]" , fileName: "( NSUUID().uuidString).jpeg" , mimeType: "image/jpeg")
multipartFormData.append(data, withName: "imgFiles[]" , fileName: "( NSUUID().uuidString).jpeg" , mimeType: "image/jpeg")
in Php side withName: "imgFiles[]" gives array of name, format , Type
在 PHP 端 withName: "imgFiles[]" 给出名称、格式、类型的数组
