I'm trying to upload a file through ASP.NET Core API. My action is:
[HttpPost]
[Route("{id}")]
public async Task<IActionResult> PostImage([FromBody] IFormFile file, [FromRoute] int id)
{
if(file.Length > 0)
{
var fileName = Path.GetFileName(file.FileName);
var fileExtension = Path.GetExtension(fileName);
var path = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot/images", "Image-" id "." fileExtension);
using (var stream = new FileStream(path, FileMode.Create))
{
await file.CopyToAsync(stream);
}
return Ok(fileName fileExtension);
}
return NotFound("File not found!");
}
When I use Postman to check its functionality, I encounter Error 415 and Visual Studio does not jump to the breaking point:
{ "type": "https://tools.ietf.org/html/rfc7231#section-6.5.13", "title": "Unsupported Media Type", "status": 415, "traceId": "00-d411f8c099a9ca4db6fe04ae25c47411-dadd8cca7cc36e45-00" }
How can I fix this problem in my code?
CodePudding user response:
If you want to receive IFormFile
, you need post content-type=multiple/form-data
which is from form data instead of body. Also remember to change [FromBody]
to [FromForm]
.
Controller:
[HttpPost]
[Route("{id}")]
public async Task<IActionResult> PostImage([FromForm] IFormFile file, [FromRoute] int id)
{}
If you post file from body, maybe you post a byte array. If though you need change IFormFile file
to byte[] file
.
