Android Question HttpJob.PostFile problem

[nibbo]

Hi All

Having a spot of bother with HttpJob.PostFile; code below:

Dim Job As HttpJob
Job.Initialize("CardImage", Me)
Job.PostFile(https://xxx.com/savefile.aspx?File=fred.jpg, File.DirRootExternal & "/" , "fred.jpg")

However this gets rejected by the server with a weird error:

Exception message: A potentially dangerous Request.Form value was detected from the client (="...�3O����<S����Ni1�Ɨ��,�...").

The event log shows Event Id 1309 code 3003; everything I have googled says I should remove the validation in the web page which I have tried but still get the same error.
This is probably a IIS issue but though I would try here first to see if anyone else has had this or may know of a fix.

Thanks in advance

HttpJob.PostFile creates a POST request with the file content as the message payload.

This will only work with a server that expects such requests.

Thanks for the reply Erel.
Got to the bottom of reason for the rejection in the end and it was an IIS config issue as I had originally thought.
The website is .NET 4 so as well as having

validateRequest="false"

in the page header a line must also be added to the config file.

<httpRuntime requestValidationMode="2.0" />

However; does anyone know what the asp should look like to retrieve and save the file on the server side?
Request.Files is empty.

Thanks

Request.Files is empty

i suggest using okhttputils2´s multipartpost method

    Dim Upload As HttpJob   
     Upload.Initialize("FileUpload",Me)
    Upload.Tag = "FileUpload"
   
    Dim fd As MultipartFileData
    fd.Initialize
    fd.KeyName = "file"
    fd.Dir = File.DirAssets
    fd.FileName = "se.jpg"
    fd.ContentType = "image/jpeg"
   
    Dim flist As List
    flist.Initialize
    flist.Add(fd)
   
    Dim NameValues As Map
    NameValues.Initialize
    NameValues.Put("uploadType","multipart")
    NameValues.Put("convert",False)
    NameValues.Put("ocr",True)
    NameValues.Put("pinned",False)
    NameValues.Put("ocrLanguage","de")
    NameValues.Put("timedTextLanguage","de")
    NameValues.Put("timedTextTrackName","de")
   
    Upload.PostMultipart(DriveUploadLink,NameValues,flist)

Thanks DonManfred; I will try this if I have to but I would rather keep it simple and use the postFile method.
I have about 40 http jobs in the project and having more than one http library has caused problems in the past.
postFile is definitely posting the data and I can see that the data server side (using Request.SaveAs) but I am not sure how to retrieve it in the aspx code behind.
I have tried Request.InputStream and Request.Files but neither contain any data.
Anyone...
Thanks

Finally worked it out so posting code here in case anyone else needs it.
The data is held in the Request.InputStream so...

Dim byteArray(Request.InputStream.Length) As Byte
Request.InputStream.Read(byteArray, 0, Request.InputStream.Length)
Dim newFile As String = System.AppDomain.CurrentDomain.BaseDirectory & "UploadedImages\fred.jpg"
Dim fs As FileStream = New FileStream(newFile, FileMode.Create)
fs.Write(byteArray, 0, byteArray.Length)
fs.Close()

Thanks to all for the replies.

Request.Files

i´m sure it will be filled when using my example-code

I am sure you are right but I have managed to get the postfile method working just fine now.
Thanks anyway.
