How do I convert this to php?

[sonnieboy]

Hello experts,

 

Please bear with me on this question.

 

I wrote this code in classic asp sometime ago. I have since gotten away from classic asp and was asked to use similar code in php.

 

First here is the asp version:

<%
Set http = Server.CreateObject("msxml2.ServerXMLHTTP")
http.Open "POST", "Authorize", False

http.setRequestHeader "Content-type","application/x-www-form-urlencoded"

http.Send Request.Form
Response.Write http.ResponseText
Response.End
%>

Here is my attempt at converting to php:

<?
Set $http = Server.CreateObject("msxml2.ServerXMLHTTP");
$http.$Open "POST", "Authorize", False;
 
$http.$setRequestHeader "Content-type","application/x-www-form-urlencoded";
 
$http.$Send Request.Form;
echo $http.$ResponseText;
Response.End;
?>

Of course it didn't work.

 

Could you please assist me with this?

 

I really appreciate your assistance in advance

Of course it didn't work.  ASP and PHP are completely different languages.  You can't expect to slap '$' in front of everything and have it work.

 

What are you trying to do?  As in, what is the programming task you're trying to accomplish?  Because it's likely there's no 1-to-1 translation.

Hi Kevin,

 

Thanks a lot for the response.

 

We have a webservice called Authorize method and due to same domain policy restrictions, we are unable to make direct ajax call to this webservice.

 

Only way is to use proxy Server.

 

The asp code allows for us to accomplish this.

The proxyAuthorize.asp file points to the webservice method, Authorize and ajax calls the webservice via the proxyAuthorize.asp.

 

Unfortunately, our current server was configured to run only php and they are asking me to change the code from asp to php.

 

Again, thanks for trying to assist.

you're going to need to use cURL for this.

Thanks Josh,

 

A few examples i tried hasn't worked.

 

Do you mind pointing me to correct example?

I'm not terribly knowledgeable about classic ASP as I stick to ASP.NET MVC 5, but it looks to me as though you need very little of your VB logic in PHP. I recommend you use cURL as well and simply supply it with all the arguments you need to do the request, then work with the data you receive back. Don't forget to close the connection.

<?php
# create the header request, though as you've indicated it's using POST, this is probably unnecessary
$request_headers = array();
$request_headers = 'Accept: application/x-www-form-urlencoded';

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, '[YourWebserviceUrlHere]');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POST, 0);
curl_optopt($curl, CURLOPT_HTTPHEADER, $request_headers);
$result = curl_exec($curl);
curl_close($curl);

# do with the $result value whatever you want here
?>

Take a look through http://php.net/manual/en/function.curl-setopt.php for the various cURL options to use with PHP.

 

And you might want to read a book on PHP before assuming that '$' before everything magically makes it PHP.

I'm not terribly versed in ASP either but based on his ASP code I think this one should be set to true:

 

curl_setopt($curl, CURLOPT_POST, true);

[sonnieboy]

Thank you good helpers.

 

I am truly grateful for your assistance.

 

captbeagle, your code did most of the heavy lifting and making that additional change by changing from 0  to true by Josh finally did the triack.

 

The code is now doing almost exactly what the asp version was doing before.

 

THANK YOU.

 

Only strange thing is that my ajax used to return a message of "invalid user or password" if username and/or password is incorrect.

 

That stopped working.

I don't know if there is any relationship between the php file and ajax.

[sonnieboy]

Sorry guys, my bad. I thought it was working. It isn't.

 

I guess I needed to cache the page before testing.

 

I will dig deeper.

 

Thanks again. You are awesome.

a lot of it depends on the server you are making the request to. If it has mechanisms in case to prevent bots, you may need to do things like fake user agent. Or if it's a secure (https) url, you'll need to set options that either handle or ignore SSL certificates and stuff. Look at the list of curl options from the link catbeagle supplied. You can also make use of curl_error() and curl_errno() to get some clues about what's going wrong.
