在html中执行.exe（C++）或转换为javascript

Question

是否可以在服务器/网页上运行EXE（C++）并使EXE返回一个响应，还是必须将此EXE（C++）转换为JavaScript的？

如果我必须将代码转换为JavaScript，我该怎么做？我知道javascript的基础知识，但我不知道如何读写.txt文件。

基本上我的代码是我想用于我的网站的登录系统，所以我不必使用mysql或数据库。我知道这样做很慢，可能是一种愚蠢的做法，但这是一个项目。任何帮助表示赞赏！

编辑：您按登录按钮，然后我提示您使用EXE文件，如上所见。然后，如果登录成功并且信息，则EXE文件将发送回服务器。 EXE文件必须在服务器上，所以客户端不必下载它。

代码：

#include <iostream> 
#include <string> 
#include <fstream> 
#include <time.h> 

using namespace std; 
void cls() { system("cls"); } 

bool mainPage(string &username, string &password) { 
    cls(); 
    cout << "Username: "; getline(cin, username); 
    cout << "Password: "; getline(cin, password); 
    if(username != "" && password != "") { 
     return true; 
    } 
    else { 
     return false; 
    } 
} 

bool checkLogin(string &username, string &password, string &email, string &firstName, string &lastName) { 
    string pw = ""; 

    ifstream ifile(username + ".txt"); 
    if(ifile.is_open()) { 
     ifile >> pw >> email >> firstName >> lastName; 
     if(pw == password) { 
      return true; 
     } 
     else { 
      return false; 
     } 
    } 
    else {

不能在文件系统从Javascript在浏览器中编写。我认为你应该使用客户端 - 服务器架构来完成你的应用程序。例如，客户端将是一个带有用户名和密码输入的简单HTML页面，服务器将保存并检查用户的凭证。在这种情况下，您可以使用Javascript将数据从页面发送到服务器。
