B4J Question HTTP Post

moore_it · Apr 15, 2024

Hi all,

how i do for posting a file on https server ?

I try with Httpjob but not work this is the errormessage.

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

this is my code ...

B4X:

mHTTP.Initialize("HTTP", Me)
        mHTTP.Username = data(4)
        mHTTP.Password = data(5)
        mHTTP.PostString(data(3),msg)

where: data(4) = username, data(5) = password, data(3) = server address, msg = string data

This means that the server certificate is not valid.
If this is a self signed certificate then you can skip verification: [B4X] OkHttpUtils2 / iHttpUtils2 and accept all option

Thanks Erel,

it's possible to post a string ?
Convert a map to byte flow but it's not a valid type for target server.

sure

Use jsongenerator to convert the Map to a jsonstring.
Post this json then.

If that does not work you should post DOCUMENTATION of the used api.
Without knowing what they expect noone can help you.

I need to post a file to UPS server

B4X:

Dim by As InputStream
by = File.OpenInput(data(1),filename)
   
Dim ff As String
    Dim tr As TextReader
    tr.Initialize2(File.OpenInput(data(1),filename),"UTF-8")
    ff = tr.ReadAll
    tr.Close
   


    Dim msg As Map
    msg.Initialize
    msg.Put("01","POST /hapld/tos/kdwhapltos HTTP/1.1"&CRLF)
    msg.Put("02","Host: www.pld-certify.ups.com"&CRLF)
    msg.Put("03","Content-type: multipart/mixed; boundary=BOUNDARY"&CRLF)
    msg.Put("04","Content-length: " & lenght &CRLF)
    msg.Put("05",CRLF)
    msg.Put("06","--BOUNDARY"&CRLF)
    msg.Put("07","Content-type: application/x-www-form-urlencoded"&CRLF)
    msg.Put("08","Content-length: 136"&CRLF)
    msg.Put("09",CRLF)
    msg.Put("10","AppVersion=1.0&AcceptUPSLicenseAgreement=Yes&ResponseType=application/x-ups-pld&VersionNumber=V4R1&UserId=" & data(4) & "&Password=" & data(5) &CRLF)
    msg.Put("11",CRLF)
    msg.Put("12","--BOUNDARY"&CRLF)
    msg.Put("13","Content-type: application/x-ups-binary"&CRLF)
    
    msg.Put("14",ff&CRLF)
    
    msg.Put("15",CRLF)
    msg.Put("16","--BOUNDARY--"&CRLF)
    
    Dim ser As B4XSerializator
    Dim b() As Byte = ser.ConvertObjectToBytes(msg)
    
    Try
        mHTTP.InitializeAcceptAll("HTTPS")
        Dim req As OkHttpRequest
        req.InitializePost2(data(3),b)
        mHTTP.Execute(req,1000)    
        ListView2.Items.Add(Chr(0xF05A)&" File inviato correttamente !")
    Catch        
        ListView2.Items.Add(Chr(0xF071)&" Errore nell'invio del file !")
        If controller <> "" Then
            ControlMail(action,controller,Chr(0xF071)&BytesToString(out.ToBytesArray, 0, out.ToBytesArray.Length, "utf8"))
        End If
    End Try
    End Try

with byte the response is :

--BOUNDARY
Content-type: text/html
Content-length: 138

<HTML>
<HEAD>
<TITLE>UPS Internet Software</TITLE>
</HEAD>
<BODY>
<P>UPS Internet Software, Copyright UPS 1998</P>
</BODY>
</HTML>

--BOUNDARY
Content-type: application/x-ups-psmpld
Content-length: 104

UPSOnLine%null%6931%6811Content-Type invalid.

--BOUNDARY
Content-type: application/x-ups-pld
Content-length: 110

00010000009710000008800026811Content-Type invalid.

--BOUNDARY--

( in another language use string in post command and work fine ).

Thanks for your help.

these code can not be valid to work with UPS. i´m pretty sure it is the wrong approach.

Check the UPS-Dcumentation on how it must be done.

What API exactly you are trying to implement? Post a link to the documentation please.

that's all

Erel · Apr 17, 2024

PostMultipart creates a multipart request. You don't need to add the boundaries yourself.

moore_it · Apr 17, 2024

Please have an example for my case ?
Thanks

With b4j I can't do a post to UPS.
If someone can please help me.

Can't test. The code may look something like this.

        Dim fd As MultipartFileData

        fd.Dir = "C:\temp"

Hi, thanks anyway for your help!

I've also tried this method but have ever this error
