Android からこの PHP コードを呼び出して、ファイルを Android からサーバーに転送し、完全に正常に動作しています。
<?php
$target_path = "./";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}
?>
しかし、私のサーバー アプリケーションは .net にあり、このコードを .net で記述する必要があります。.net バージョンのコードを記述しようとしましたが、動作せず、500 internal server error
.
public partial class uploadfiles : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
try
{
HttpFileCollection uploadFile = Request.Files;
if (uploadFile.Count > 0)
{
HttpPostedFile postedFile = uploadFile[0];
System.IO.Stream inStream = postedFile.InputStream;
byte[] fileData = new byte[postedFile.ContentLength];
inStream.Read(fileData, 0, postedFile.ContentLength);
postedFile.SaveAs(Server.MapPath("Data") + "\\" + postedFile.FileName);
}
}
catch (Exception ex)
{
StringBuilder sb = new StringBuilder();
sb.AppendLine("Message : " +ex.Message);
sb.AppendLine("Source : " + ex.Source);
sb.AppendLine("StackTrace : " + ex.StackTrace);
sb.AppendLine("InnerException : " + ex.InnerException);
sb.AppendLine("ToString : " + ex.ToString());
LogInToFile(sb.ToString());
}
}
}
例外をログに記録しないか、最初の行に到達していないと思います。Logファイルで確認しました。それは機能しません。助けてください。
