如何使用带有令牌和参数的Alamofire来上传图片？ [英] How to upload image using Alamofire with token&parameters?
问题描述
我不知道我是否添加令牌&参数正确与否。
使用Alamofire有什么不对？
有什么建议吗？
谢谢。
$ b $ pre $
func uploadWithAlamofire（image：UIImage，imageData：Data，imageUrl：URL）{
let parameters = [avatar：imageData]
Alamofire.upload（multipartFormData：{multipartFormData in
multipartFormData.append（imageData，withName：user.id，fileName：\\ （key，value）的参数{
multipartFormData.append（value，withName：key）$（$ key $ value $） b $ b}
}到：apiUrl，方法：.put，headers：[Authorization：Bearer \（token）]，
encodingCompletion：{encodingResult in
switch encodingResult {
case .success（let upload，_，_）：
upload.response {[self self]]
guard self！= nil else {
return
}
debugPrint（响应）
}
case .failure（让encodingError）：
print（error：\（encodingError））
}
}）
}
func imagePickerController（_ picker：UIImagePickerController，didFinishPickingMediaWithInfo info：[String：Any]）{
photoImage = info [UIImagePickerControllerOriginalImage] as！ UIImage
photoImageView.image = photoImage
imageName：String = user.id +.jpg
let documentsPath = NSHomeDirectory（）。appending（/ Documents / Icon / ）
let imagePath = documentsPath.appending（imageName）
let imageUrl = URL（fileURLWithPath：imagePath）
print（imageUrl is here：\（imageUrl））
让imageData：Data = UIImageJPEGRepresentation（photoImage，0.001）！
do {
尝试imageData.write（to：imageUrl，options：.atomic）
} catch let error {
print（error）
}
$ b $ uploadWithAlamofire（image：photoImage，imageData：imageData，imageUrl：imageUrl）
self.dismiss（animated：true，completion：nil）
}
试试这个：
$ b $ pre $ func uploadImageWith（param params：Dictionary< String，String>，image：UIImage？，handler：@escaping（（Dictionary< String，Any> ？，Int） - > Void））{
// let keyJson =json.dataUsingEncoding（NSUTF8StringEncoding）！
print（Params：\（params））
let BASE_URL =http：//
alamofire.upload（
multipartFormData：{multipartFormData in
对于（键，值）参数{
multipartFormData.append（value.data（使用：String.Encoding.utf8，allowLossyConversion：false）！，withName：键）
}
if image！= nil {
let imgData = UIImageJPEGRepresentation（image !, 0.5）
if imgData！= nil {
multipartFormData.append（imgData !,带名称：photo_upload，fileName ：file.png，mimeType：image / png）
}
}
}，
to：BASE_URL，
encodingCompletion：{encodingResult in
switch encodingResult {
case .success（let upload，_，_）：$ b $ upload.responseJSON {response in
switch response.result {
case .success：
如果让jsonDict = response.result.value as？字典<字符串，不限> {
print_debug（Json Response：\（jsonDict））//序列化的json响应
处理程序（jsonDict，（response.response！.statusCode））
}
else {
handler（nil，（response.response！.statusCode））
}
如果让data = response.data，则让utf8Text = String（data：data，encoding：.utf8）{
print（服务器响应：\（utf8Text））//原始服务器数据为UTF8字符串
}
break
case .failure（let error）：
处理程序（nil，（response.response！.statusCode））
break
}
}
case .failure（让encodingError）：$ b $ print（encodingError）
}
}
）
}
USE $ b
uploadImageWith（param：[key：value]，image：UIImage（name：icon））{（response，statusCode）in
print（response）
}
您必须传递params和image对象并且在闭包中获得作为Dictionary对象的响应。
I use Alamofire to upload images, however the upload is unsuccessful.
I also bring token & parameters to server.
I don't know whether I add token & parameters correctly or not.
What's wrong with me to using Alamofire?
Have any suggestion?
Thanks.
func uploadWithAlamofire(image:UIImage, imageData:Data, imageUrl:URL) {
let parameters = ["avatar":imageData]
Alamofire.upload(multipartFormData: { multipartFormData in
multipartFormData.append(imageData, withName: user.id, fileName: "\(user.id).jpg", mimeType: "image/jpg")
for (key, value) in parameters {
multipartFormData.append(value, withName: key)
}
}, to: apiUrl , method: .put, headers: ["Authorization": "Bearer \(token)"],
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.response { [weak self] response in
guard self != nil else {
return
}
debugPrint(response)
}
case .failure(let encodingError):
print("error:\(encodingError)")
}
})
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
photoImage = info[UIImagePickerControllerOriginalImage] as! UIImage
photoImageView.image = photoImage
let imageName:String = user.id + ".jpg"
let documentsPath = NSHomeDirectory().appending("/Documents/Icon/")
let imagePath = documentsPath.appending(imageName)
let imageUrl = URL(fileURLWithPath: imagePath)
print("imageUrl is here:\(imageUrl)")
let imageData:Data = UIImageJPEGRepresentation(photoImage, 0.001)!
do {
try imageData.write(to: imageUrl,options: .atomic)
} catch let error {
print(error)
}
uploadWithAlamofire(image: photoImage, imageData: imageData, imageUrl: imageUrl)
self.dismiss(animated: true, completion: nil)
}
Try this:
func uploadImageWith(param params:Dictionary<String,String>,image:UIImage?,handler:@escaping ((Dictionary<String,Any>?,Int) -> Void)) {
// let keyJson = "json".dataUsingEncoding(NSUTF8StringEncoding)!
print("Params:\(params)")
let BASE_URL = "http://"
Alamofire.upload(
multipartFormData: { multipartFormData in
for (key, value) in params {
multipartFormData.append(value.data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName: key)
}
if image != nil{
let imgData = UIImageJPEGRepresentation(image!, 0.5)
if imgData != nil {
multipartFormData.append(imgData!, withName: "photo_upload", fileName: "file.png", mimeType: "image/png")
}
}
},
to: BASE_URL,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
switch response.result {
case .success:
if let jsonDict = response.result.value as? Dictionary<String,Any> {
print_debug("Json Response: \(jsonDict)") // serialized json response
handler(jsonDict,(response.response!.statusCode))
}
else{
handler(nil,(response.response!.statusCode))
}
if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
print("Server Response: \(utf8Text)") // original server data as UTF8 string
}
break
case .failure(let error):
handler(nil,(response.response!.statusCode))
break
}
}
case .failure(let encodingError):
print(encodingError)
}
}
)
}
USE
uploadImageWith(param: ["key":"value"], image: UIImage(name:"icon")) { (response, statusCode) in
print(response)
}
You have to pass the params and image object and you get the response as a Dictionary object in closure.
