How do you know the real name of the system file in the Golan?
We need to create a file in the Windows software catalogue.
For example, ProgramFiles% doesn't work.
How do you know the folder of the / operating system, etc?

Go 1.15 added the method https://golang.org/pkg/net/url#URL.Redacted ♪ who works as*net/url.URL.String♪ but replaces the password if it is,xxxxx:fmt.Println(u) // Output: // // https://user:password@example.com fmt.Println(u.Redacted()) // Output: // // https://user:xxxxx@example.comI'm recommending that the method be wrapped. String Always. back.

before leaving the form(s)r.FormValue("name")You have to dissolve her.if err := r.ParseForm(); err != nil { fmt.Fprintf(w, "ParseForm() err: %v", err) return "" } But there's another problem, when the page is downloaded for the first time, we're making a GET request, and when we fill the form, we need to make a POST request, the problem is, it's the same hendler that handles.You can trace what type of request to determine behavior. For example,func GetFormText(w http.ResponseWriter, r *http.Request) string { switch r.Method { case "GET": http.ServeFile(w, r, "./login.html") case "POST": if err := r.ParseForm(); err != nil { fmt.Fprintf(w, "ParseForm() err: %v", err) return "" } fmt.Fprintf(w, "Post from website! r.PostFrom = %v\n", r.PostForm) name := r.FormValue("name") fmt.Fprintf(w, "Name = %s\n", name) return name default: fmt.Fprintf(w, "Sorry, only GET and POST methods are supported.") } return "" }

First byte, send the length of the file's name, the next four bytes is the length of the file, the trail of the file's name, and then the bayta of the file itself. Or, in order to keep up with the data envelope, you can expand the field a little bit:Server.javapackage com.example; import java.io.File; import java.io.FileInputStream; import java.io.OutputStream; import java.io.IOException; import java.nio.ByteBuffer; import java.net.ServerSocket; import java.net.Socket; public class Server { private static int PORT = 2121; private static String FOLDER = "./files"; public static void main(String[] args) { File sourceDir = new File(FOLDER); try (ServerSocket listener = new ServerSocket(PORT)) { while (true) { try (Socket socket = listener.accept(); OutputStream out = socket.getOutputStream()) { for (String fileName : sourceDir.list()) { // Преобразовываем строку, содержащую имя файла, // в массив байт byte[] name = fileName.getBytes("utf-8"); // Отправляем длину этого массива out.write(name.length); // Отправляем байты имени out.write(name); File file = new File(FOLDER + "/" + fileName); // Получаем размер файла long fileSize = file.length(); // Конвертируем его в массив байт ByteBuffer buf = ByteBuffer.allocate(Long.BYTES); buf.putLong(fileSize); // И отправляем out.write(buf.array()); try (FileInputStream in = new FileInputStream(file)) { // Читаем файл блоками по килобайту byte[] data = new byte[1024]; int read; while ((read = in.read(data)) != -1) { // И отправляем в сокет out.write(data); } } catch(IOException exc) { exc.printStackTrace(); } } } catch(IOException exc) { exc.printStackTrace(); } } } catch(IOException exc) { exc.printStackTrace(); } } } Client.javapackage com.example; import java.io.File; import java.io.FileOutputStream; import java.io.InputStream; import java.io.IOException; import java.nio.ByteBuffer; import java.net.Socket; public class Client { private static int PORT = 2121; private static String HOST = "localhost"; private static String FOLDER = "./files"; public static void main(String[] args) { try (Socket s = new Socket(HOST, PORT); InputStream in = s.getInputStream()) { // Читаем размер имени int nameSize; while((nameSize = in.read()) != -1) { // Читаем само имя byte[] name = new byte[nameSize + 1]; in.read(name, 0, nameSize); // Преобразовываем обратно в строку String fileName = new String(name, "utf-8").trim(); System.out.println(fileName); File file = new File(FOLDER + "/" + fileName); try (FileOutputStream out = new FileOutputStream(file)) { // Читаем размер файл byte[] fileSizeBuf = new byte[8]; in.read(fileSizeBuf, 0, 8); // Преобразовываем в long ByteBuffer buf = ByteBuffer.allocate(Long.BYTES); buf.put(fileSizeBuf); buf.flip(); long fileSize = buf.getLong(); // Читаем содержимое файла блоками по килобайту int read = 0; byte[] data = new byte[1024]; while (read < fileSize) { read += in.read(data); // И пишем в файл out.write(data); } } catch(IOException exc) { exc.printStackTrace(); } } } catch(IOException exc) { exc.printStackTrace(); return; } } }

If you file a file like files.txt, use it:fopen('files.txt','a');fwrite и fclose;Example:<html> <head> <title>Результат загрузки файла</title> <meta charset="utf-8"> </head> <body> <?php if($_FILES["filename"]["size"] > 102481024) { echo ("Размер файла превышает три мегабайта"); exit; } // Проверяем загружен ли файл if(is_uploaded_file($_FILES["filename"]["tmp_name"])) { // Если файл загружен успешно, перемещаем его // из временной директории в конечную move_uploaded_file($_FILES["filename"]["tmp_name"], "".$_FILES["filename"] ["name"]); echo("Загружен"); if($f=fopen('files.txt','a')){ fwrite($f,$_FILES["filename"]["name"]."\n"); fclose($f); } } else { echo("Ошибка загрузки файла"); } ?>

Which stage will I add if the same name file exists? When creating list.txt? Or when processing a file by one line?If you specify the condition when creating list.txt, it will be overwritten if you create a new file before creating a file.If the same name file exists, it does not understand the condition addition, adding consecutive numbers instead of overwritingPowershell is suitable for detailed operation such as acquisition of serial number.# 変数を変更して実行すること Move-Mp3 -Path "D:\test\src" -Dest "D:\test\dst" -IsMove $false <# .SYNOPSIS 指定フォルダ以下のファイルを移動またはコピーし、移動先に同名ファイルが存在する場合は連番を付加する .DESCRIPTION 指定された移動元フォルダから特定拡張子のファイルを再帰的に取得して、指定された出力先に移動またはコピーする。出力先に同名ファイルが存在する場合は連番を付加して上書きを回避する。移動元フォルダの構成は再現せず、出力先フォルダ直下に直接移動またはコピーを行う。 .PARAMETER Path 移動元フォルダのパス。 .PARAMETER Dest 移動またはコピーする出力先フォルダのパス。 .PARAMETER Filter ファイル名や拡張子などのフィルタ。省略時は"*.mp3" .PARAMETER IsMove $trueの場合は移動、$falseの場合はコピーを行う。省略時は移動する .NOTES 出力先フォルダが存在しない場合はエラーとなる。 #> function Move-Mp3 { Param( [parameter(mandatory=$true)][String]$Path, [parameter(mandatory=$true)][String]$Dest, [String]$Filter = "*.mp3", [bool]$IsMove = $true ) ls -Path $Path -Filter $Filter -Recurse | foreach { $src = $_.FullName $name = $_.Name $target = "${Dest}\${name}" while (Test-Path $target) { $f = [System.IO.Path]::GetFileNameWithoutExtension($name) $x = [System.IO.Path]::GetExtension($name) $r = [regex]"^(.*?)([0-9]+)$" $m = $r.Match($f) if($m.Success) { # 末尾の数値をカウントアップ $index = [int]$m.Groups[2].Value + 1 $name = "{0}{1}{2}" -f $m.Groups[1].Value, $index, $x } else { # 末尾に数値がなければ拡張子の前に"-1"を追加 $name = "{0}-1{1}" -f $f, $x $index++ } $target = "${Dest}\${name}" } if($IsMove) { move $src $target "$src を $target に移動しました。" } else { copy $src $target "$src を $target にコピーしました。" } } } Initially, I tried to implement bat file, but it was troublesome to extract serial numbers.If you want to open a bat file even with a half-sided implementation example, please refer to the answer before fixing from the history.

Of course, if privateFunc does not use the MyStruct field, you don't have to do it by this structure, so you're just gonna mess up people. The name of the function begins with a small letter, so outside the mypackage, it's still not gonna be visible, and more usually not.Anyway, it's like you're trying to bring your habits from other CPs to Go, but they don't have a full analog, different languages, their ideology and approaches, so, too. In this case, just call a function with a small letter and have it in the same file as MyStruct. If that's not enough, you can write another comment where you can explain what and where the function is intended. There are no other funds in the Go, and in this case, I do not see their necessity personally. It's a pure water of "industing."

Use the toilet. find♪ It's quite universal. She has an operator. -size Just to figure out the size of the files. For example,find каталог -type f -size -100c Turns out the names of all regular files that are exactly below 100 bays,find каталог -type f -size -1k Also removes files whose size is less than 1 KB.Less before numbers means " smaller " .This program has a pretty interesting operator. -printfallowing for a variety of information on the file. As an example,find каталог -type f -printf '%p %s\n' | column -t He'll take the size of the files on the terminal.Details of the list of parameters can be found in the manual http://manpages.ubuntu.com/manpages/xenial/en/man1/find.1.html ♪

Based on the code, see:10-15 requests per second = 10-15 new compounds with base,That is a huge overhead, wasteful use of resources and a completely unacceptable architectural code.Each (!) connection may be required up to 2M memory and some time (in seconds or milliseconds, depending on the operational availability of the server). It ends up like a scary shutdown. Besides, I'm sure the base itself can easily cut this number of compounds.Normal programming practices - to meet queries (Query, Execute) to the superstructure only one Connection (Connection) which should be maintained in active condition during the life of the form or page. In other words, we must first create an ODE connection to the base and then use it in all requests.Sematically (without reference to any programming language) this should look like:ConnectionObj = New(Connection) // создали соединение с БД //начинаем интенсивно использовать единственное и достаточное соединение //для выполнения кучи запросов: //пример использования для возврата датасета DataSet = ConnectionObj.Query('SELECT * FROM Users') //пример использования без возврата датасета ConnectionObj.Execute('DROP TABLE Users') //Выполнили свои задачи, наигрались, закрываем соединение и уничтожаем объект ConnectionObj.Close ConnectionObj.Free // или = nil, null, и т.д.

You did the package import, but did not put the name of the package before the function GetFunction, to correct, type the package name before using the function, for example:functions.GetFunction() In addition, it may be necessary to go get, configure the GOPATH etc.I created exactly the example in github to explain in practice: https://github.com/Dadinel/so497165

you will have to explode(explode()) the file name and with the resulting array add the date, follows the example:$nomeETipo = explode('.',$file['name']); $fileName = $nomeETipo[0].date('dmY') . "." . $nomeETipo[1]; where $nomeETipo[0] is the file name and $nomeETipo[1] is the file extension.

The problem is that the method doInBackground() receives a parameter varargs. The varargs parameters work as an array. When you get the toString() from the parameter, you get the toString() from a not String array. To solve the problem you only have to get the String that contains the varargs parameter in the zero position. For example:String nombre = strings[0]; A method with a varargs parameter can receive an indetermined amount of arguments. To access these arguments you use an index in the varargs parameter, as if it were an array.public void metodo(String... textos) { System.out.println(textos[0]) System.out.println(textos[1]) System.out.println(textos[2]) } metodo("Hola", "Mundo", "!"); // Imprime: // // Hola // Mundo // !
