Ios 如何在不使用Alamofire的情况下，在swift 4中以相同的密钥名上传阵列中的多个图像

签出单个图像上载的代码，但无法在同一密钥下上载阵列中的多个图像

在下面的代码中， 当我向服务器发送一个图像时，它工作得非常好。 ->我想在不使用alamofire或其他第三方库的情况下找到阵列中多个图像的答案

      func imageUploadRequest(IMAGE_ARRAY: [UIImage] , uploadUrl: NSURL) {

        myloader.showLoader(controller: self)
      let param = ["title":"ds","category_id":"5","description":"gdfjghjdsfgksd","user_id":"66","color":"red"]

        let request = NSMutableURLRequest(url:uploadUrl as URL)
        request.httpMethod = "POST"
        let boundary = generateBoundaryString()
        request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")

        //let imageData = UIImageJPEGRepresentation(imageView.imageOrientation, 0.1)
        for item in IMAGE_ARRAY
        {
            let imageData = item.jpegData(compressionQuality: 0.01)
            if(imageData==nil)  { return; }

            request.httpBody = createBodyWithParameters(parameters: param as [String : Any], filePathKey: "files[]", cv : imageData! as NSData, boundary: boundary) as Data
        }

        // myActivityIndicator.startAnimating();

        let task =  URLSession.shared.dataTask(with: request as URLRequest,
                                               completionHandler: {
                                                (data, response, error) -> Void in
                                                if let data = data {
                                                    DispatchQueue.main.async { // Update UI
                                                        self.myloader.removeLoader(controller: self)
                                                        let decoder = JSONDecoder()

                                                        let obj = try! decoder.decode(GetResponse_Otp.self, from: data)


                                                    }
                                                }
        })
        task.resume()
    }

    func createBodyWithParameters(parameters: [String: Any]?, filePathKey: String?, cv: NSData, boundary: String) -> NSData {
        let body = NSMutableData();

        if parameters != nil {
            for (key, value) in parameters! {

                body.appendString("\(value)\r\n")

        body.appendString("--\(boundary)--\r\n")

        return body
    }

    func generateBoundaryString() -> String {

您需要将密钥名称更改为密钥\名称[]在密钥中添加数组[]，并确保每次文件名都不同，或者您也可以尝试以下操作：

(Date().timeIntervalSince1970).jpeg

以确保名称每次都不同

     myloader.showLoader(controller: self)

     if(imageData==nil)  { return; }

     request.httpBody = createBodyWithParameters(parameters: param as [String : Any], filePathKey: "KEY_NAME[]", cv : imageData! as NSData, boundary: boundary) as Data

请重试：再次阅读问题，我询问如何在不使用AlamofReach的情况下在swift 4中以相同的键名在数组中上载多个图像根据您的回答，所有图像将设置在不同的键上。我们如何以相同的键发送图像数组没有键将与image_key[]相同，但图像名称每次都不同。如果可能，请您共享一个代码，这将很有帮助，我尝试了，但无法执行。此错误发生兄弟：-2019-11-07 15:13:20.761172+0530 wows[5938:150457]致命错误：“重试！”表达式意外引发错误：Swift.DecodingError.dataCorrupted（Swift.DecodingError.Context（codingPath:[]，debugDescription:“给定的数据不是有效的JSON.”，underyingerror:Optional（error Domain=nscocaerordomain Code=3840“结尾垃圾”。.UserInfo={NSDebugDescription=结尾垃圾。}））：file/Users/rahulrai/Desktop/wows/Controller/AddProductVC.swift，第212行将此
