gistlib - ssh file upload c# in javascript

To upload a file to a remote server using SSH with C# and JavaScript, you will need to use an SSH library for C# and also use JavaScript to handle the user interaction and file selection. Here's an example project that uses the Renci.SshNet library in C# and JavaScript to upload a file to a remote server over SSH:

Install the Renci.SshNet NuGet package to your C# project.


main.cs
using Renci.SshNet;
using System.IO;

string host = "yourserver.com";
string username = "yourusername";
string password = "yourpassword";
string uploadPath = "/path/to/remote/folder";
string localFilePath = "C:\\local\\file\\path.txt";

using (var ssh = new SshClient(host, username, password))
{
    ssh.Connect();

    using (var sftp = new SftpClient(ssh.ConnectionInfo))
    {
        sftp.Connect();
        using (var fileStream = new FileStream(localFilePath, FileMode.Open))
        {
            sftp.UploadFile(fileStream, uploadPath, true);
        }
        sftp.Disconnect();
    }

    ssh.Disconnect();
}

Add a file input to your HTML with an ID so you can easily access it with JavaScript:


<input type="file" id="fileInput">

Add some JavaScript to handle the file selection and upload:


index.tsx
const fileInput = document.getElementById('fileInput');
const uploadButton = document.getElementById('uploadButton');
const statusMessage = document.getElementById('statusMessage');

const getFormData = file => {
  const formData = new FormData();
  formData.append('file', file);
  return formData;
};

uploadButton.addEventListener('click', () => {
  const file = fileInput.files[0];
  const formData = getFormData(file);

  const xhr = new XMLHttpRequest();
  xhr.onreadystatechange = function() {
    if (xhr.readyState === 4) {
      if (xhr.status === 200) {
        statusMessage.innerHTML = 'Upload successful!';
      } else {
        statusMessage.innerHTML = `Error uploading file: ${xhr.statusText}`;
      }
    }
  };
  xhr.open('POST', 'upload.php', true);
  xhr.send(formData);
});

Add a PHP script to receive the file and call the C# method to upload it via SSH. You will need to modify the C# code above to accept the file upload path as an argument instead of using a hardcoded path.


main.php
<?php
if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    $tempPath = $_FILES['file']['tmp_name'];
    $uploadPath = '/path/on/remote/server';
    $command = "your C# command here with $uploadPath parameter";

    shell_exec($command);

    echo 'File uploaded!';
} else {
    echo 'Error uploading file: ' . $_FILES['file']['error'];
}

Note: This is just an example to get you started. You should implement proper error handling and make sure to secure your PHP script to prevent unauthorized file uploads.
