将文件上传到 ASP.NET Core 中不同服务器上 wwwroot 之外的文件夹

Question

我正在尝试将文件上传到位于 ASP.NET Core 项目的托管服务器之外的文件夹。我尝试了不同的方法，但到目前为止都没有奏效。我也尝试使用 fttp 上传，但服务器提供商不允许这样做。这是我的代码

        public async Task<IActionResult> DevicePhotoGalary(int id, IFormFile file) // IFormFile for one Photo and IFormCollection for Multi Photo
        {
            var QuestionObj = await _questionRepo.GetQuestionById(id);
            if (QuestionObj == null)
                return NotFound();

            var uploadFolderPath = Path.Combine(_webHostEnvironment.WebRootPath, "IQ Questions"); //location must be changed here

            if (!Directory.Exists(uploadFolderPath))
                Directory.CreateDirectory(uploadFolderPath);

            var fileName = Guid.NewGuid().ToString() + Path.GetExtension(file.FileName);
          

            var filePath = Path.Combine(uploadFolderPath, fileName);
            // var filePath = uploadFolderPath + fileName;
            using (var stream = new FileStream(filePath, FileMode.Create))
            {
                file.CopyTo(stream);
            }

            QuestionObj.Image =  fileName;
            await _questionRepo.UpdateQuestion(QuestionObj);

            return Ok(); 
}

非常感谢任何帮助。谢谢

如果您不能在您的服务器中使用 FTP。最简单的方法是在需要上传文件的服务器上部署一个简单的web程序，程序包含上传接口。

然后就可以在DevicePhotoGalary方法中调用接口了。

如下代码

---

public IActionResult DevicePhotoGalary( IFormFile file) 
{
    var uploadFolderPath = Path.Combine(_webHostEnvironment.ContentRootPath, "IQ Questions"); //location must be changed here

    if (!Directory.Exists(uploadFolderPath))
        Directory.CreateDirectory(uploadFolderPath);

    var fileName = Guid.NewGuid().ToString() + Path.GetExtension(file.FileName);


    var filePath = Path.Combine(uploadFolderPath, fileName);
    // var filePath = uploadFolderPath + fileName;
    using (var stream = new FileStream(filePath, FileMode.Create))
    {
        // Invoke api in the server which will save the content
        //file.CopyTo(stream);
    }

    return Ok();
}
