我正在尝试上传带有参数（multipartformdata）的文件，但是我无法使用新版本的Alamofire 5进行上传，如果您有使用Alamofire 5的经验，请与我分享。
func uploadPluckImage(imgData : Data, imageColumnName : String, url:String,httpmethod:HTTPMethod,completionHandler: @escaping (NSDictionary?, String?) -> ()){
let token = UserDefaults.standard.string(forKey: PrefKeys.loginToken) ?? ""
let authorization = ["Authorization" : "Bearer \(token)"]
let parameters: Parameters?
parameters = [
"garbageCollector": 0,
"stuff_uuid": "2b4b750a-f4a6-4d61-84ce-7c42b5c030ee",
"delete_file" : ""
]
let headers : HTTPHeader?
headers = ["Authorization" : "Bearer \(token)"]
let imageURl = "http://68.183.152.132/api/v1/stuff/uploader"
AF.upload(multipartFormData: { (multipart: MultipartFormData) in
let imageData = self.firstImage.image?.jpegData(compressionQuality: 0.7)
multipart.append(imageData, withName: "file", fileName: "file.png", mimeType: "image/png")
for (ker, value) in parameters!{
multipart.append(value as! String).data(using: .utf8)!, withName: key)
}
},usingThreshold: UInt64.init(),
to: imageURl,
method: .post,
headers: headers,
encodingCompletion: { (result) in
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (progress) in
print("Uploading")
})
break
case .failure(let encodingError):
print("err is \(encodingError)")
break
}
})
}

Alamofire 5中的上传方法稍有改变
func upload(image: Data, to url: Alamofire.URLRequestConvertible, params: [String: Any]) {
AF.upload(multipartFormData: { multiPart in
for (key, value) in params {
if let temp = value as? String {
multiPart.append(temp.data(using: .utf8)!, withName: key)
}
if let temp = value as? Int {
multiPart.append("\(temp)".data(using: .utf8)!, withName: key)
}
if let temp = value as? NSArray {
temp.forEach({ element in
let keyObj = key + "[]"
if let string = element as? String {
multiPart.append(string.data(using: .utf8)!, withName: keyObj)
} else
if let num = element as? Int {
let value = "\(num)"
multiPart.append(value.data(using: .utf8)!, withName: keyObj)
}
})
}
}
multiPart.append(image, withName: "file", fileName: "file.png", mimeType: "image/png")
}, with: url)
.uploadProgress(queue: .main, closure: { progress in
//Current upload progress of file
print("Upload Progress: \(progress.fractionCompleted)")
})
.responseJSON(completionHandler: { data in
//Do what ever you want to do with response
})
}
希望这对您有帮助

这对我来说适用于Swift 4.2或更高版本。请尝试
let url = "http://google.com" /* your API url */
let headers: HTTPHeaders = [
/* "Authorization": "your_access_token", in case you need authorization header */
"Content-type": "multipart/form-data"
]
Alamofire.upload(multipartFormData: { (multipartFormData) in
for (key, value) in parameters {
multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key as String)
}
if let data = imageData{
multipartFormData.append(data, withName: "image", fileName: "image.png", mimeType: "image/png")
}
}, usingThreshold: UInt64.init(), to: url, method: .post, headers: headers) { (result) in
switch result{
case .success(let upload, _, _):
upload.responseJSON { response in
print("Succesfully uploaded")
if let err = response.error{
onError?(err)
return
}
onCompletion?(nil)
}
case .failure(let error):
print("Error in upload: \(error.localizedDescription)")

这是我如何使用Alamofire 5从swift 5应用程序上传图像和视频的方法。
图片
/**
Send Image to server
*/
func Post(imageOrVideo : UIImage?){
let headers: HTTPHeaders = [
/* "Authorization": "your_access_token", in case you need authorization header */
"Content-type": "multipart/form-data"
]
AF.upload(
multipartFormData: { multipartFormData in
multipartFormData.append(imageOrVideo!.jpegData(compressionQuality: 0.5)!, withName: "upload_data" , fileName: "file.jpeg", mimeType: "image/jpeg")
},
to: "http://ip.here.--.--/new.php", method: .post , headers: headers)
.response { resp in
print(resp)
}
}
您可以创建临时资源并使用临时网址（适用于视频）：
/**
Send video to server
*/
func PostVideoUrl(url : URL){
let headers: HTTPHeaders = [
"Content-type": "multipart/form-data"
]
AF.upload(
multipartFormData: { multipartFormData in
multipartFormData.append(url, withName: "upload_data" , fileName: "movie.mp4", mimeType: "video/mp4")
},
to: "http://ip.here.--.--/newVideo.php", method: .post , headers: headers)
.response { resp in
print(resp)
}
}

您可以使用路由器URLRequestConvertible
static func performMultiPartFile<T:Decodable>(imageData: Data, route:APIRoute,decoder: JSONDecoder = JSONDecoder(), completion: @escaping (_ result: T?, _ error: String?) -> ()) {
Alamofire.upload(multipartFormData: { (multipartFormData) in
multipartFormData.append(imageData, withName: "image", fileName: "iosImage.jpg", mimeType: "image/jpg")
}, with: route) { (encodingResult) in
switch encodingResult {
case .success(let upload, _, _):
upload.responseString { (response) in
if response.result.isSuccess {
if let JSON = response.result.value {
debugPrint("✅ Respons Object >>>> " + String(describing: JSON))
do {
let result = try JSONDecoder().decode(T.self, from: JSON.data(using: .utf8)!)
debugPrint("✍️ Result: " + String(describing: result))
completion(result, nil)
} catch let error { // mapping fail
debugPrint("❌ Error in Mapping" + String(describing: error))
completion(nil, String(describing: error))
}
}
} else {
debugPrint("❌ ? Response fail : \(response.result.description)")
completion(nil, (response.result.error?.localizedDescription)!)
}
}
case .failure(let encodingError):
completion(nil, String(describing: encodingError))
}
}

for (key, value) in parameters {
if let temp = value as? String {
multipartFormData.append(temp.data(using: .utf8)!, withName: key)
}
if let temp = value as? Int {
multipartFormData.append("\(temp)".data(using: .utf8)!, withName: key)

if let temp = value as? NSArray {
temp.forEach({ element in
let keyObj = key + "[]"
if let string = element as? String {
multipartFormData.append(string.data(using: .utf8)!, withName: keyObj)
} else
if let num = element as? Int {
let value = "\(num)"
multipartFormData.append(value.data(using: .utf8)!, withName: keyObj)
}
})
}
}
if let data = imageData{
multipartFormData.append(data, withName: "file", fileName: "\(Date.init().timeIntervalSince1970).png", mimeType: "image/png")

onError?(err)
