Please I have been trying to upload pictures from a xamarin form application to a php server but seems not to be working. The server receives an empty $_FILES request. This is the c# code.
public async Task<bool> Upload(MediaFile mediaFile, string filename)
{
byte[] bitmapData;
var stream = new MemoryStream();
mediaFile.GetStream().CopyTo(stream);
bitmapData = stream.ToArray();
var fileContent = new ByteArrayContent(bitmapData);
fileContent.Headers.ContentType = MediaTypeHeaderValue.Parse("application/octet-stream");
fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
{
Name = "fileUpload",
FileName = filename
};
string boundary = "---8393774hhy37373773";
MultipartFormDataContent multipartContent = new MultipartFormDataContent(boundary);
multipartContent.Add(fileContent);
HttpClient httpClient = new HttpClient();
HttpResponseMessage response = await httpClient.PostAsync("http://www.url.com/upload.php", multipartContent);
response.EnsureSuccessStatusCode();
if (response.IsSuccessStatusCode)
{
string content = await response.Content.ReadAsStringAsync();
return true;
}
return false;
}
Below is the php file to receive the uploaded image. I tried to save the content of the posted image to file but the file only has an empty array and always return "failure". Please what am i missing wrong? I have searched the web but cant seem to understand the problem.
$uploads_dir = 'uploads/';
$req_dump = print_r( $_FILES, true );
$fp = file_put_contents( 'data.txt', $req_dump );
if (isset($_FILES["fileUpload"]["tmp_name"]) AND is_uploaded_file($_FILES["fileUpload"]["tmp_name"]))
{
$tmp_name = $_FILES["fileUpload"]["tmp_name"];
$name = $_FILES["fileUpload"]["name"];
$Result = move_uploaded_file($tmp_name, "$uploads_dir/$name");
echo "Success";
}
else
{
echo "Failure";
}
