Hello!
I'm trying to post an XML file over Http. I would like to send an xml file to an .aspx link. I'm using Embarcadero 2010 ( C++).
In this line
Http->Post("https://...aspx", pInputXML, pOutputXML);
i get the error: http/1.1 404 Not Found
Why i get the error? The Link exists...
I have no idea. What can i do?
I'm glad, if i get help.
Greetings

Hey thank you for your answer!
It expect the raw XML.
I create an XML file with the information and i send the xml to the given link. Its for Online Sales. The purchase informations are in the xml file and i must send it to the .aspx link.
What can be the ways i can go? Only the link and the xml file are given. I don't have more informations.
i created this code:
std::auto_ptr httpPtr( new TIdHTTP(NULL) );
TIdHTTP *Http = httpPtr.get();
try
{
TIdSSLIOHandlerSocketOpenSSL *SSL = new TIdSSLIOHandlerSocketOpenSSL(Http );
Http->IOHandler = SSL;
Http->HandleRedirects = true;
Http->AllowCookies = false;
Http->ConnectTimeout = 10000;
Http->ReadTimeout = 10000;
Http->Request->BasicAuthentication = true;
}
catch( const Exception &e )
{}
TMemoryStream *pInputXML = new TMemoryStream;
pInputXML->LoadFromFile("C:\\CBUILDER2010.src\\Project\\order.xml");
try
{
TMemoryStream *pOutputXML = new TMemoryStream;
try
{
Http->Request->ContentType = "text/xml";
Http->Request->Method = 'POST';
Http->Post("https://....aspx", pInputXML, pOutputXML);
}
__finally
{
delete pOutputXML;
}
}
__finally
{
delete pInputXML;
}
When i try this link i get : „http/1.1 404 not found“
When i try an other link i get: „socket error #0“
My Indy version is 10.5.5. Shall i upgrade my version? If yes, how can i do that?
I hope, that is the right version.
Thank you for your help,
greetings

I need to do that. the company for the I establish the connection told me, that i need to send the Raw XML as part of the post.

i wrote this part of code after the load from file method:
pInputXML->Position = 0;
I hope it is correct.

Thank you for the tip regarding the software fiddler.
I opened my page, to which i need to send my xml and i get the information:
- Accept: text/html, application/xhtml+xml, */*
- Accept-Language: de-DE,de;q=0.5
- Result 200
So i interpret that its possible to arrange a connection to this "https:// ... .aspx" page.
> Is the TIdHTTP::OnRedirect event being triggered? Or does the TIdHTTP::Response::Location

I wrote this code ( before i use the post method, because the program stop when i access the post method):
Http->OnRedirect; // result ---> {NULL, NULL}
Http->Response->Location; // result ---> {NULL}
If i debug this step by step i get the informations, that OnRedirect and Location are {NULL};
with which informations can i set the properties?
I don't know whats wrong.
Thank you for your help!
greetings

I opened the page in my internet explorer for the test.
If i opened the page, its empty.
But its there.
There is no field which can be filled.
But my instructions are i must post the raw xml to the given link...i know nothing more.

The selected session is a HTTP CONNECT Tunnel. This tunnel enables a client to send raw traffic (e.g. HTTPS-encrypted streams or WebSocket messages) through a HTTP Proxy Server (like Fiddler).

- Where can i find the Parameter 'dest'? I can't find it in the variable overview. i only found Idtcpclient::TIdTCPClientCustom::FDestination and the value is {NULL}.
> and does that URL actually exist on the server?
- I think so, because my task is to build a connetion to it

I added this to my code:
try
{
TIdSSLIOHandlerSocketOpenSSL *SSL = new TIdSSLIOHandlerSocketOpenSSL(Http );
Http->IOHandler = SSL;
//Http->HandleRedirects = true;
Http->HandleRedirects = false;
Http->ConnectTimeout = 10000; <----
Http->ReadTimeout = 10000;<----
}
I changed HandleRedirects to true, i get the error 404. I changed it to false, i get the same error.
With this code i get the 404 error. ( i comment out my Proxy so i avoid the 'Read timed out' Exception.)
When i try a another link from that company, where a code is indicated on the page, i get the code 302. But when i use the link i need i get 404 not found. And in the next step i get Socket Error #0.
It is why i don't set Http->Connect(); ?
When i try this, i need to set a host. But i don't know where and which.
> That being said,
> have you tried the TIdLog... alternative yet?
I took the TIdLogFile Property. I named the File. I searched the file and found it in my EXE directory. But it is empty :(
> you are not actually requesting the literal string "https://........aspx", are

> correct?
yes it is masked. Because of privacy.
I erased all manually set properties from the TIdHTTP->Request. Its default now.
I only allow Cookies and Handle Redirects. The IOHandler is set to SSL. The defaultport of it is 443. The IPVersion is Id_IPv4. And that's all.
Like my TIdSSLIOHandlerSocketOpenSSL I/O Handler (default port = 443, SSL Option = sslvSSLv23, Mode = sslmClient).
I hope you can help out of the trap (figuratively). :)
greetings!

Hi!

>or else TIdHTTP did not transmit/receive any data at all. Since you are

I've set the property to true.
But the file is still empty.
I tried the link with the 302 answer.
I started my program and now i get the content from my dest variable.
The content is "/XML...aspx/.../Login"
Its the page where i can test my xml file. When iam on this page, i manually need to change the URL's (change the 302 URL to the 404 URL) and then i can place the order(manually with klick the button).
Why can i place the order in this way, but it does not work if i call post with the 404 URL? I can't explain it.
(Ps.: if i manually copy and paste the 404 link in my browser the result is, that the shown page is empty. But there is no error.)
I tested the Http->Head("https://.....aspx"); method, to check, if the service is responsive. I get the "Read timed out" exception.
Do i need to update my Indy version? Do the program everytime output the Socket error #0 and finish my program or will the program scroll through the code?
Until now the post command will be executed and then i'll get the socket error and my program ends.
I downloaded the new version from Indy (from http://www.indyproject.org/sockets/download/files/indy10.en.aspx). But its the version 10.0.52. If i'll update my current version with that version i'll downgrade my Indy.
How can i update my version? Can u give me a manual and a link how i can find the right Indy version ?
Currently i ignore this error.
:(
>For example:
>Http->Post("https://hostname/...aspx", ...); // defaults to port 443
>Http->Post("https://hostname:12345/...aspx", ...); // port 12345
Thank you for explanation.

Hi!
So now i get only the Socket Error #0 error.
But my order do not arrive.
I think, that my Http Client don't send data.
Is it ok that my UserAgent is "Mozilla/3.0 (compatible; Indy Library)"?
std::auto_ptr httpPtr( new TIdHTTP(NULL) );
TIdHTTP *Http = httpPtr.get();
Http->OnRedirect = &HttpRedirect;
try
{
TIdSSLIOHandlerSocketOpenSSL *SSL = new TIdSSLIOHandlerSocketOpenSSL(Http );
Http->IOHandler = SSL;
Http->HandleRedirects = true;
Http->OnRedirect;
Http->Response->Location;
Http->ConnectTimeout = 10000;
Http->ReadTimeout = 10000;
}
catch( const Exception &e )
{
ShowMessage( e.Message );
}
TStringStream *s = new TStringStream;
TMemoryStream *pInputXML = new TMemoryStream;
pInputXML->LoadFromFile("C:\\CBUILDER2010.src\\Project\\xml.xml");
pInputXML->Position = 0;
try{
TMemoryStream *pOutputXML = new TMemoryStream;
try
{
pInputXML->SaveToStream(s);
s->DataString;
Http->Post(URL , pInputXML, pOutputXML); //when it reach the post method it takes a couple of seconds and don't walk through
pOutputXML->SaveToStream(s);
s->DataString;
}
__finally
{
delete pOutputXML;
delete pInputXML;
}
}

Hi!
I started my program and now the URL get a wrong redirection (detect the wrong host), post() recognize the wrong host and Fiddler is be ignored.
The program stop by reach the post(method) and begin at the start. The post method is like a break up.
What's wrong?
Yesterday it redirected right.
best regards

Here is it:
try
{
Http->ProxyParams->ProxyServer = "127.0.0.1"; // do not work --> Fiddler isn't active ( I started the fiddler program before i run my program)
Http->ProxyParams->ProxyPort = 8888;// do not work ---> it's not enough to set proxyserver and port. There is no effect. When i use fiddler with google chrome it works fine. But with Embarcadro it doesn't work.
Http->Request->ContentType = "text/xml";
std::auto_ptr httpPtr( new TIdHTTP(NULL) );
TIdHTTP *Http = httpPtr.get();
Http->IOHandler = new TIdSSLIOHandlerSocketOpenSSL(Http);
Http->HandleRedirects = true;
Http->ConnectTimeout = 10000;
Http->ReadTimeout = 10000;
Http->OnRedirect = &HttpRedirect;
std::auto_ptr pInputXML( new TMemoryStream );
pInputXML->LoadFromFile("C:\\\CBUILDER2010.src\\\Project\\\xml.xml");
pInputXML->Position = 0;

When you reach the post() method you will see, that the program stops for a couple of seconds an start at "try" again. It's not run beyond the post() method
That's what i mean.
Ps.: Do you receive my message?
