此功能将仅发送小视频。如何更改此设置以发送 100 MB 视频？服务器限制设置为 200 MB。上传视频时，我将视频的文件路径发送到 SQL Db，并将具有唯一 ID 的视频发送到文件管理器。如果视频小于 5MB，则返回成功添加的消息，如果视频超过 5MB，则文件管理器中没有视频。我试图得到这个，但我无法解决它。

据我了解，Swift/NSURLSession 不会将大量数据加载到内存中。

有人可以告诉我如何将其转换为工作。 

func uploadVideo2 (){


    //Bool to control Post Activity Indicator.isHidden
    DispatchQueue.main.async(execute: {
    self.videoOnOff = "on"
    self.postActivityIndicatorIsHidden()
    })

    //Here we get the card's UUID to be used with the param
    let unquieID  =  theDictionary.value(forKey: "unquieID") as! String

    // param to be sent in body. This will be used in the $_request variable in the DBVideo.php
    let param = ["videoUnquieID" : unquieID] //This is the card's UUID

    // url path to php file
    let url = URL(string: "xxxx://xxx.xxxxxxxx.xxx/xxx/DBVideo.php")!

    // Adding the url to the request variable
    var request = URLRequest(url: url)

    // Declare POST method
    request.httpMethod = "POST"

    // Assign video to videoData variable
    let videoData = theDictionary.value(forKey: "theVideo") as! Data

    // Creat a UUID for the boundary as a string
    let boundary = "Boundary-\(UUID().uuidString)"

    //Set the request value to multipart/form-data     the boundary is the UUID string
    request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")


    request.httpBody = createBodyWithParamsVideo(param, //This is the card's UUID
                                                 filePathKey: "file", //The path to the variable $_FILES in the DBVideo.php
                                                 imageDataKey: videoData as Data, //The video's data from the card
                                                 boundary: boundary) // A unquie ID setup just for the baundary

    // launch session
   URLSession.shared.dataTask(with: request) { data, response, error in

        if response != nil {
        }

        // get main queue to communicate back to user
        DispatchQueue.main.async(execute: {
            if error == nil {
                do {
                    // json containes $returnArray from php  //converting resonse to NSDictionary
                    let json = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? NSDictionary

                    DispatchQueue.main.async(execute: {
                    self.videoOnOff = "off" //Controls for the Activity indicator
                    self.postActivityIndicatorIsHidden() //Activity indicator
                    })


                    // declare new parseJSON to store json
                    guard let parseJSON = json else {
                        print("Error while parsing")

                        DispatchQueue.main.async(execute: {
                        self.contactImageOnOff = "off" //Controls for the Activity indicator
                        self.postActivityIndicatorIsHidden() //Activity indicator
                        })
                        return
                    }

                    var msg : String!

                    //getting the json response
                    msg = parseJSON["message"] as! String?

                    //printing the response
                    print(msg)


                    // error while jsoning
                } catch {
                     let message = error
                    print(message)
                 }

                // error with php
            } else {
                //no nothing
            }
        })
        }.resume()
}

这是PHP

    <?php

    //STEP 1. Check to see if data was passed to this php file
    if (empty($_REQUEST['videoUnquieID'])) {
        $returnArray["massage"] = "Missing required information";
    return;
    }

    // Pass POST via htmlencryot and assign to $id
    $id = htmlentities($_REQUEST['videoUnquieID']);


    //STEP 2. Createing the $folder variable to hold the path where the video will be placed
    $folder = "VBCVideo/";


    //STEP 3. Move uploaded file
    $folder = $folder . basename($_FILES["file"]["name"]);

    if (move_uploaded_file($_FILES["file"]["tmp_name"], $folder)) {
        $returnArray["status"]="200";
        $returnArray["message"]="The Video file has been uploaded";
    } else {
        $returnArray["status"]="300";
        $returnArray["message"]="Error while uploading the Video";
    }


     //STEP 4. Build connection
     //Constructor to create connection
        function __construct()
        {
            require_once dirname(__FILE__) . '/Config.php';
            require_once dirname(__FILE__) . '/DbConnect.php';
            // opening db connection
            $db = new DbConnect();
            $this->connect = $db->connect();
        }


     // STEP 5. Feedback array to app user
     echo json_encode($returnArray);

     ?>

php.ini

    max_execution_time = 500000;
    upload_max filesize = 200000M;
    post_max_size = 400000M;
    memory_limit = 200000m;
