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

Answer 1

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{

                        }
                    case .failure(let encodingError):
                        print("error:\(encodingError)")
