I have a one question for yours . I have dev. one project , I need your helps . I have one post service to be taken byte array and will be convert to image again for me. I have one picture , i converted this image to byte[], I did send byte[] using BinaryWriter if you wants looking my code
public void SendData()
{
var item = Directory.GetFiles(@"C:\Users\nazmi\Desktop\s");
//Bitmap bmp = new Bitmap(item[0]);
//var stream = new MemoryStream();
//bmp.Save(stream, ImageFormat.Jpeg);
//var imageBytes = stream.ToArray();
Bitmap bmp = null;
bmp = new Bitmap(item[0]);
var stream = new MemoryStream();
bmp.Save(stream, bmp.RawFormat);
var imageBytes = stream.ToArray();
// string sendString = System.Text.Encoding.UTF8.GetString(imageBytes);
//MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length);
//ms.Write(imageBytes, 0, imageBytes.Length);
//Image returnImage = Image.FromStream(ms, true);
//returnImage.Save(@"C:\Users\Nazmi\Desktop\123.tiff");
// File.WriteAllBytes(@"C:\Users\Nazmi\Desktop\123.txt", imageBytes);
var url = "http://localhost:28862/api/BinaryEncodeDecode";
var httpRequest = (HttpWebRequest)WebRequest.Create(url);
httpRequest.Method = "POST";
httpRequest.Accept = "application/json";
httpRequest.ContentType = "application/json";
var data = @"{ 'byteArray': '" imageBytes "' }";
using (var writer = new BinaryWriter(httpRequest.GetRequestStream()))
{
writer.Write(data);
var httpResponse = (HttpWebResponse)httpRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
}
//using (var streamWriter = new StreamWriter(httpRequest.GetRequestStream()))
//{
// streamWriter.Write(data);
//}
}
And will be share with you my rest service you are looking my code if you want ->
public async Task<IActionResult> PostAsync()
{
try
{
var binary = new BinaryReader(Request.Body);
byte[] allData = binary.ReadBytes(1054);
return Ok("Başarılı");
}
catch (Exception ex)
{
return BadRequest(ex.Message);
throw;
}
}
My byte[] length is so big but i taken only 34 . I tried so many way . Please help me .
CodePudding user response：
application/json is for communicating with JSON encoding, byte array is not a json object. you need to set your httpRequest.Accept and httpRequest.ContentType to application/octet-stream
CodePudding user response：
i solved this problem.
int length = (int)(Request.ContentLength ?? 0);
byte[] content = new byte[length];
await Request.Body.ReadAsync(content, 0, length);
this code block solved my problem
