I want to post-send the file from the UWP application to the PHP application on the server side, but the file fails to be sent.
The failure is that the $_FILES decision on the PHP side is always false.
I have sent two parameters.
- param1 is a string value
- param2 is the upload file
if ($_FILES['param2'])
private async Task PostSample()
{
const string POST_URL = "http://xxx.xxx.xxx.xxx/api/sample.php";
var multi=new HttpMultipartFormDataContent();
varparam1 = new HttpStringContent("foo");
multi.Add (param1, "param1");
byte [ ] values = new byte [ ] { 0x20, 0x20, 0x20, 0x20, 0x20, 0x20 };
varparam2 = new HttpStreamContent(new MemoryStream(values).AsInputStream());
param2.Headers.ContentDisposition=newWindows.Web.Http.Headers.HttpContentDispositionHeaderValue("form-data")
{
Name = "param2",
FileName="piyo.dat"
};
multi.Add (param2);
varclient = new HttpClient();
var res = wait client.PostAsync (new Uri(POST_URL), multi);
vardiag = new MessageDialog(res.ToString());
wait diag.ShowAsync();
}
The Google Chrome app Advanced REST Client succeeded (if($_FILES['param2']) is true.
private async Task PostSample()
{
const string POST_URL = "http://xxx.xxx.xxx.xxx/api/sample.php";
var multi=new MultipartFormDataContent();
var param1 = new StringContent("foo");
multi.Add (param1, "param1");
byte [ ] values = new byte [ ] { 0x20, 0x20, 0x20, 0x20, 0x20, 0x20 };
varparam2 = new StreamContent (new MemoryStream (values));
param2.Headers.ContentDisposition=newSystem.Net.Http.Headers.ContentDispositionHeaderValue("form-data")
{
Name = "param2",
FileName="piyo.dat"
};
multi.Add (param2);
varclient = new HttpClient();
var res = wait client.PostAsync(POST_URL, multi);
MessageBox.Show(res.ToString());
}
Therefore,
I suspect that the code on the UWP side is incorrect, missing, or some specification on the UWP side, but I don't know why.
I would appreciate it if you could give me some advice on the direction of the investigation.
It may be inappropriate, but I also posted it on the English version of Stackoverflow yesterday.However, it seems that the view doesn't work in the first place, so I also posted it here.
If it is not appropriate, I will delete it, so I would appreciate it if you could let me know.

If WinForm works with almost the same code, it is possible that the app does not have permission to send data to the outside world.
