- ESP32-CAM capture image and update that image in Google Drive (II).

We are going to change the Script code, we will use part of the @TIMAI2 code to update the image that we will call capture.jpg

function doPost(e) {
  var data = Utilities.base64Decode(e.parameters.data);
// var nombreArchivo = Utilities.formatDate(new Date(), "GMT-3", "yyyyMMdd_HHmmss")+".jpg";
  var filename = "capture.jpg";
  var blob = Utilities.newBlob(data, e.parameters.mimetype, filename);
  
  var folder, folders = DriveApp.getFoldersByName("ESP32-CAM");
  if (folders.hasNext()) {
    folder = folders.next();
  } else {
    folder = DriveApp.createFolder("ESP32-CAM");
  }
  
  var existing = folder.getFilesByName(filename);
    if (existing.hasNext()) {
      var file = existing.next();
      if (file.getName() == filename) {
          fileID = file.getId();
         // Drive.Files.update({title: filename, mimeType: mimetype}, fileID, blob); 
          Drive.Files.update({title: filename,  mimeType: file.getMimeType()}, fileID, blob); 
      }
    } else {
    blob = Utilities.newBlob(data, e.parameters.mimetype, filename);
    fileID = folder.createFile(blob).getId(); 
    }
  
 // var file = folder.createFile(blob); 
  
  return ContentService.createTextOutput("Completo.")
}

We can locate the key of the file and put it in an Image component within a Clock, every certain interval the image will be updated on the screen.
