ios - 如何使用此数据分段上传

Question

我想以多部分的形式将此数据与图像/视频一起发送到服务器。我有字节数据形式的图像/视频数据(NSData 或 Data)

{"mediauploadata":
  {
"type":"poll",
"server_token":"03f0e635b4c01b9f398de393259de8650b54c85c24f49998af50593643f559230d95e8e605612653769f4871b543e25d48bf",
"id":"105"
   }
 }

我使用 Alamofire 创建了一个用于分段上传的函数。

通过传递 Web 服务 URL、参数和您的图像来调用此函数。

func WSPostAPIMultiPart(_ aStrULR:String,
                        param: [String: Any],
                        image : UIImage?,
                        controller: UIViewController,
                        successBlock: @escaping (_ response:[String : Any]?) -> Void,
                        failureBlock: @escaping (_ error: Error?) -> Void) {

    var dictHeaders : HTTPHeaders = [String : String]()

    if (Alamofire.NetworkReachabilityManager()?.isReachable)!{
    Alamofire.upload(
        multipartFormData: { MultipartFormData in

            let JSONData: Data? = try? JSONSerialization.data(withJSONObject: param, options: .prettyPrinted)
            MultipartFormData.append(JSONData!, withName: "json")
            if image != nil{
                 MultipartFormData.append(UIImageJPEGRepresentation(image!, 0.5)!, withName: "profile_image",fileName: "image.jpeg", mimeType: "image/jpeg")
                // withName : You will pass the key name required by your server
            }

    }, to: aStrULR ,method : .post , headers : dictHeaders) { (result) in

        switch result {
        case .success(let upload, _, _):

            upload.responseJSON { response in

                if let value = response.result.value   {
                    let dictResponse = JSON(value).dictionaryObject

                    successBlock(dictResponse)
                }
            }

        case .failure(let error):
            failureBlock(error)
        }
    }
    }else{
        print("NO INTERNET CONNECTIVITY")
    }
}

对于视频:只需向 videoURL 传递一个额外参数并附加为:

MultipartFormData.append(videoUrl, withName: "profileVideo", fileName: "video.mp4", mimeType: "video/mp4")

希望有帮助:)
