我尝试使用MultipartFormData.append(((value as AnyObject).data(using: String.Encoding.utf8.rawValue))!, withName: key)
,但是它说value没有成员数据

在func下面尝试一下,它正在工作。
func uploadImage(urlString : String , image : UIImage, param : [String : Any], completionHandler : @escaping ( _ result : Any?) -> ()) {
guard let imageData = UIImageJPEGRepresentation(image, 0.5) else {
print("Could not get JPEG representation of UIImage")
return
}
Alamofire.upload(multipartFormData: { multipartFormData in
for (key, value) in param {
multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key as String)
}
multipartFormData.append(imageData,
withName: "image",
fileName: "image.jpg",
mimeType: "image/jpeg")
},
to: urlString,
headers: ["Authorization": "Basic xxx"],
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.uploadProgress { progress in
}
upload.validate()
upload.responseJSON { response in
completionHandler(response.result.value)
}
case .failure(let encodingError):
print(encodingError)
completionHandler(nil)
}
})
}

这是使用其他API参数上传视频和图像的功能。
func uploadWithAlamofire(Parameters params : [String: Any]?,ImageParameters imgparams : [NSObject : AnyObject]?,VideoParameters vidoparam : [NSObject : AnyObject]?,Action action : NSString, success: @escaping (AnyObject) -> Void, failure: @escaping (AnyObject) -> Void)
{
var base_url = BASEURL
base_url.append(action as String)
print(base_url)
var headers : HTTPHeaders = [:]
if let token = UserDefaults.standard.value(forKey: "webToken"){
headers = ["JWT-Authorization": "Bearer \(token)"]
}
Alamofire.upload(multipartFormData: { multipartFormData in
if imgparams != nil{
for (key, value) in imgparams! {
if let imageData = UIImageJPEGRepresentation(value as! UIImage, 1) {
multipartFormData.append(imageData, withName: key as! String, fileName: "\(NSDate().timeIntervalSince1970 * 1000)).jpg", mimeType: "image/jpg")
}
}
}
if vidoparam != nil{
for (key, value) in vidoparam! {
multipartFormData.append(value as! URL , withName: key as! String, fileName: "\(NSDate().timeIntervalSince1970 * 1000).mp4", mimeType: "application/octet-stream")
}
}
if params != nil
{
for (key, value) in params! {
multipartFormData.append((value as! String).data(using: .utf8)!, withName: key as! String)
}
} }, to: base_url, method: .post, headers: headers,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.uploadProgress { progress in
print(progress.fractionCompleted)
}
upload.response { [weak self] response in
guard self != nil else {
return
}
let responseString = String(data: response.data!, encoding: String.Encoding.utf8)
var dictonary:NSDictionary?
if let data = responseString?.data(using: String.Encoding.utf8) {
do {
dictonary = try JSONSerialization.jsonObject(with: data, options: []) as? [String:AnyObject] as NSDictionary?
if dictonary != nil{
if dictonary?.value(forKey: "status_code") as! String == "200"{
return success(dictonary!)
}else{
print(dictonary?.value(forKey: "status_code")! as Any)
let errorMsg : Any = Int(dictonary?.value(forKey: "status_code") as Any)
utility.showAlertWithStatusCode(code: errorMsg)
