上传数据到Alamofire使用通常的方式像张贴其他数据

Question

    let parameters = [
        "profile_picture" : "(profilePictureData)",
    ]
    Alamofire.request(.POST, UPDATE_PROFILE_PICTURE_URL + "token=(userToken)", parameters: parameters, encoding: .JSON, headers: AUTHENTICATION_HEADER).response { (request, response, data, errorType) -> Void in
        if(data != nil) {
            let responseStr:NSString = NSString(data:data!, encoding:NSUTF8StringEncoding)!
            print(responseStr);
            let resultObject: APIResults = APIResults(JSONDecoder(data!));
            let responseCode: Int = Int(resultObject.code!)!;
            if(responseCode == 200) {
                succeeded = true;
            }
        }
    }

到目前为止，这是我的代码，我试图发布我的profilePictureData，这是一个NSData到服务器，就像我通常如何发送字符串或Int。我将profilePictureData放到body参数中。这总是失败，服务器返回错误。

我应该如何发送我的图像数据到服务器?

请帮助。谢谢你

使用这个作为模型。请根据需要编辑。

Alamofire.upload(.POST,
        URLString: "https://example.com/api/v1/users/(user_id)/profile_pic.json?auth_token=(auth_token)",
        multipartFormData: { multipartFormData in
            multipartFormData.appendBodyPart(data: imageData, name: "avatar", fileName: "avatar_img.png", mimeType: "image/png")
        },
        encodingCompletion: { encodingResult in
            switch encodingResult {
                case .Success (let upload, _, _):
                    upload.responseJSON { request, response, data, error in
                    // Do whatever 
                    } 
                case .Failure (let encodingError):
                    //Realistically, I don't expect this to ever trigger, but I guess if the user uses some very weird image format...
            }
        })
