Hello, I am making a cross-platform app and I need to make some POST request in the background I managed to do that for Android with HttpClient and I am using NSUrlSessionto achieve this for IOS.
I was able to make a normal HTTP post with string params but I can't figure out how to do it with a multipart/form-data as a content type.
Can someone please guide me through this, I am literally stuck for like a week.
I found some swift and objective C code, but unfortunately, I know nothing about these two languages.
This is my code for the moment, I've read somewhere that I have to write the body myself, I tried that but it didn't work.
using (var url = NSUrl.FromString(UploadUrlString))
using (var request = new NSMutableUrlRequest(url))
string boundaryConstant = "------WebKitFormBoundaryizZlLeb5a0mTyHtJ";
request.HttpMethod = "POST";
request["Cookie"] = "SERVERIDxxx=xxxxxx";
var data = NSData.FromArray(MyPhotoByteArray);
var uiimage = UIImage.LoadFromData(data);
NSData img = uiimage.AsJPEG(1);
string Body = boundaryConstant+ "\r\n";
Body += "Content-Disposition: form-data; name=\"id\"\r\n\r\n";
Body += 50000+ "\r\n";
Body += boundaryConstant + "\r\n";
Body += "Content-Disposition: form-data; name=\"upload_file\"; filename=\"Untitled.png\"\r\n";
Body += "Content-Type: image/png\r\n\r\n";
Body += boundaryConstant + "--";
request.Body = NSData.FromString(Body);
request["Content-Type"] = "multipart/form-data; boundary="+ boundaryConstant;
NSUrlSessionDownloadTask downloadTask = session.CreateDownloadTask(request);
