Re: [twsocket] Posting
Hi, I apologize. Figured it out. The problem was just that the URL didn't have a trailing slash and for whatever reason this created a problem. I added a trailing slash and it worked great.

Re: [twsocket] Posting unicode data in HTTP Post
Hi,
Thanks for your help, but still I am not getting the same results when I do
post to php script.
This is PHP script
> echo "Note = ". $_POST['note'];
>
> if($_POST['action'] == 'i')
> {
> /*
> * This code will add new notes to the database
> */
> $sql = "INSERT INTO app_notes VALUES ('', '" .
> mysql_real_escape_string($_POST['username']) . "', '" .
> mysql_real_escape_string($_POST['note']) . "', NOW(), '')";
> $result = mysql_query($sql, $link) or die('0 - Ins');
> echo '1 - ' . mysql_insert_id($link);
> ?>
>
and this is the delphi code:
data := Format('date=%s&username=%s&password=%s&hash=%s¬e=%s&action=%s',
[UrlEncode(FormatDateTime('mmddhh:nn',now)),
UrlEncode(edtUserName.Text), UrlEncode(getMd5(edtPassword.Text)),
UrlEncode(getMd5(dataHash)),UrlEncode(Utf8Encode(memoNote.Text)),'i' ]); //
try function StrHtmlEncode (const AStr: String): String; from IdStrings
HttpCli1.SendStream := TMemoryStream.Create;
HttpCli1.SendStream.Write(Data[1], Length(Data));
HttpCli1.SendStream.Seek(0, 0); HttpCli1.RcvdStream :=
TMemoryStream.Create; HttpCli1.URL := Trim(ActionURLEdit.Text);
HttpCli1.PostAsync;
But the PHP script is getting totaly different characters ?
Any clue what this can be?
Thanks.

That's easy to explain. UrlEncode takes a AnsiString, memoNote.Text
is of type WideString. Assigning a WideString to a String causes
an implicit and silent conversion from WideString to AnsiString
which uses the default system code page. However if the WideString
contained any character that cannot be converted to the current ANSI
code page those characters are replaced by question marks.
So UrlEncode(Utf8Encode(memoNote.Text)) should do the trick.

GetMD5() doesn't look like an ICS function since there is no
overloaded GetMD5() in v5 that takes a string.

It works as URL encoding should work:
Characters '0'..'9', 'A'..'Z', 'a'..'z' are left untouched,
any Char outside these rages are encoded "'%' +
IntToHex(Ord(AnsiChar))"
It does not look like an ICS issue to me?

Re: [twsocket] Posting unicode data in HTTP Post
Yes it is Tnt Memo. I am using widestring from Tnt, I was thinking that Tnt
is in utf-8?
Anywhay if I use urlencode on the character from Tnt Memo I am getting '?'
as result.
What should solve my problems with posting from Tnt Memo using ICS?

Why should one display UTF-8 strings in a AnsiString memo?
Anyway just to be sure, UTF-8 is a AnsiString (one byte element
size of the data array), WideString contains UTF-16 data with two
byte element size of the data array.
Question: Does memoNote.Text contain UTF-8 or UTF-16?
Maybe it's a TNT memo which contains WideStrings?

Ah, ok.

What kind of problems do you have exactly? Can you show some code?
With POST you just write data to a stream which is send as is.
There is an example how to post multi-byte form data on the
User-Made page on ICS website.

GetMD5() doesn't look like an ICS function since there is no overloaded
GetMD5() in v5 that takes a string.

It works as URL encoding should work:
Characters '0'..'9', 'A'..'Z', 'a'..'z' are left untouched,
any Char outside these rages are encoded "'%' + IntToHex(Ord(AnsiChar))"
It does not look like an ICS issue to me?

Re: [twsocket] Posting unicode data in HTTP Post
Hi,
Here is code:
data :=
Format('date=%s&username=%s&password=%s&hash=%s¬e=%s&action=%s',
[UrlEncode(FormatDateTime('mmddhh:nn',now)),
UrlEncode(edtUserName.Text),
UrlEncode(getMd5(edtPassword.Text)),
UrlEncode(getMd5(dataHash)),UrlEncode(memoNote.Text),'i'
]);
This memoNote.text is utf-8 this doesn't work with unicode characters? Is it
fixed in new versions?
HttpCli1.SendStream := TMemoryStream.Create;
HttpCli1.SendStream.Write(Data[1], Length(Data));
HttpCli1.SendStream.Seek(0, 0);
HttpCli1.RcvdStream := TMemoryStream.Create;
HttpCli1.URL := Trim(ActionURLEdit.Text);
HttpCli1.PostAsync;
Thanks.

THttpCli, SSL enabled use CONNECT method (This is mandatory for HTTPS !). If you have ICS-SSL, you may have a look at how it is implemented. At first glance it is not too difficult to implement also for non-ssl part of the component. You are welcome to do it of course. > Or should I start with a vanilla TWSocket and work my way from that?

I'll re-explain how my downstream (that is - HTTP download) connection works. The client requests a document from my web server. It does this going through the proxy. The server response (200 OK), does NOT send an Content-length header and starts sending the document very very slowly, but it keeps sending for ever. It looks just like a large file download over a very slow link. Since there's no Content-length header the proxy is unable to determine if the document has finished downloading or not, it will keep receiving the given document for as long as the server sends. I noticed the proxy does one other nice thing: it immediately relays all received data to the client, and it really makes sense. Real-life example that should force the proxy to behave in this very same manner: The client is downloading a 4Gb ISO image through the proxy. The proxy can't possibly wait for the WHOLE download to finish before starting to relay data to the client, it just doesn't make sense. It must start sending data to the client as soon as data is available. What I'm thinking about is using the very same thing the other way around: Doing a slow POST! I do understand downloading and uploading are governed by different rules, so I'd like to try this too. If you still say it's unlikely to work, I'll stop trying (by now I'm sure I explained things clearly enough so there's no misunderstanding). >> On a different note, how do programs like "zebedee" provide a TCP/IP >> tunnel through a HTTP proxy?

If the proxy server does the same for the "long HTTP post" it would provide a very valuable tool for what I need. If it doesn't work I'll simply use as many HTTP posts as necessary. And if it makes any difference, for this part of my application I control both the "client" and the "server"; It's the potential proxy in the middle I'm not controlling. I need to use HTTP to make sure it works through the proxy. On a different note, how do programs like "zebedee" provide a TCP/IP tunnel through a HTTP proxy?

HTTP protocol is a stateless protocol and you have poor connection control. Just ask for the connection to be kept alive and hope it is. If it isn't, then it will be reopened anyway by the component. > If it doesn't work I'll simply use as many HTTP posts as necessary. That is much safer. If you are sure you have ONLY ICS component at both side, you can be sure of the behaviour. But anything between has just to be compliant with HTTP protocol and what you ask is more. > On a different note, how do programs like "zebedee" provide a TCP/IP > tunnel through a HTTP proxy? I understand how the "downstream" part > works, but how about the "upstream" part? This is quite easy. You can send the command "CONNECT" to a HTTP proxy and then the proxy will work transparently as a simple relay, without ever trying to understand what you send in the stream. This is how HTTPS works thru the proxy. Since HTTPS encrypt everything, the proxy is unable to do anything. It can just relay the data.

But probably it is not what you really want. Since you control the client part, why not send as many HTTP requests as you need ? > without closing the connection. You have not full control of connection close with HTTP protocol. If the server decide to close it, it will be closed. You can request a persistant connection using the property Connection and setting 'keep-alive' string as value. See also ProxyConnection property used when traversing a proxy. > Is it possible? > Will it work through an HTTP proxy? A post which never ends may have problem with filtering proxies because they will not see the end of document and maybe they are buffering the document until the end before processing it. So it would not works. If you use many post one after the other, there will be no special problem. Contribute to the SSL Effort.

[twsocket] Posting data to web server using THttpCli under user control

[twsocket] POSTing images to a server
Hi! I've just started to play with the Httpcli component and I'm hoping to create a program that will allow me to post images to a web application. The basic POST works now - I can submit data to a form. But, I can't begin to get my head around the things involved in posting images to the application. I understand that I need to post it as a multi-part form with a suitable separator for the parts, then set the correct MIME type and content type, and encode the data. Has anyone tried this? Is there some sample that I could refer to? (I'm using BC++ Builder 5 right now) Thanks, Mohit. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
