froala图片明明上传成功了，还是会提示，遇到些错误，请在试试，原来还是php控制器的错误

最终发现是php的问题

正确的php如下

  public function fr_upload(){
      
        try {
          // File Route.
          $fileRoute = ROOT_PATH . 'public/uploads/';
        
          $fieldname = "multipartFile";
        
          
          // Get filename.
          $filename = explode(".", $_FILES[$fieldname]["name"]);
        //   halt($filename);
          // Validate uploaded files.
          // Do not use $_FILES["file"]["type"] as it can be easily forged.
          $finfo = finfo_open(FILEINFO_MIME_TYPE);
        
          // Get temp file name.
          $tmpName = $_FILES[$fieldname]["tmp_name"];
        
          // Get mime type.
          $mimeType = finfo_file($finfo, $tmpName);
        
          // Get extension. You must include fileinfo PHP extension.
          $extension = end($filename);
        
          // Allowed extensions.
          $allowedExts = array("gif", "jpeg", "jpg", "png", "svg", "blob");

          // Validate image.
          if (!in_array(strtolower($mimeType), $allowedMimeTypes) || !in_array(strtolower($extension), $allowedExts)) {
            throw new \Exception("File does not meet the validation.");
          }
        
          // Generate new random name.
          $name = sha1(microtime()) . "." . $extension;
        //   halt( dirname(__FILE__));

          // Save file in the uploads folder.
          move_uploaded_file($tmpName, $fullNamePath);

        //   halt($fullNamePath);
        
        //   // Check server protocol and load resources accordingly.
