UniServer 5-Nano
PHP cURL.

cURL GET POST SSL and Authentication
This page contains no new material what it provides are examples using our test simulation server to accesses a verification server over SSL to submit a form.
It takes the examples from the previous page and adds authentication and SSL.
Preperation
Our verification server curl_2 has already been configured
- A default server certificate and key have been generated
- Appropriate lines in C:\curl_2\UniServer\ssl\.htaccess are enabled
All that remains is to copy C:\curl_2\UniServer\www\remote_form.php to folder C:\curl_2\UniServer\ssl
Perhaps add a line to distinguish the form see last line:
<?php
print "<p><b>Method GET</b><br />";
if(isset($_GET['Name'])) $Name = $_GET['Name'];
if(isset($_GET['Password'])) $Password = $_GET['Password'];
if(isset($_GET['Message'])) $Message = $_GET['Message'];
print "Name = $Name<br />";
print "Password = $Password<br />";
print "Message = $Message</p>";
print "<p><b>Method POST</b><br />";
if(isset($_POST['Name'])) $Name = $_POST['Name'];
if(isset($_POST['Password'])) $Password = $_POST['Password'];
if(isset($_POST['Message'])) $Message = $_POST['Message'];
print "Name = $Name<br />";
print "Password = $Password<br />";
print "Message = $Message</p>";
print "<p>SSL TEST FORM</p>";
?>
Example 12 - cURL GET
Using example 10 add the appropriate target page, password and SSL functions:
- curl_setopt($ch, CURLOPT_URL,'https://localhost:446/remote_form.php');
- curl_setopt($ch, CURLOPT_USERPWD, "root:root");
- curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // no verify
Create a new text file in folder C:\curl_1\UniServer\www and name it test12.php add the following content
<?php
$name_val = urlencode('MPG RIC');
$password_val = urlencode('fred 123');
$message_val = urlencode('This is a test & = ?');
$str= "?Name=".$name_val."&Password=".$password_val."&Message=".$message_val;
print $str;
$ch=curl_init();
curl_setopt($ch, CURLOPT_URL,'https://localhost:446/remote_form.php'.$str);
curl_setopt($ch, CURLOPT_USERPWD, "root:root");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // no verify
curl_exec($ch);
curl_close($ch);
?>

- First three lines URL encode the values we wish to send.
- Full string $str is assembled into correct format name value pairs.
- This string is concatenated with the URL (tacked onto the end)
- Added new URL remember is https and the port must be included
- Added CURLOPT_USERPWD again defaults are root root
- CURLOPT_SSL_VERIFYPEER disabled
Test:
- Run both servers
- Type http://localhost/test12.php into your browser
- Result: Shown below
|
Results:
?Name=MPG+RIC&Password=fred+123&Message=This+is+a+test+%26+%3D+%3F
Method GET
Name = MPG RIC
Password = fred 123
Message = This is a test & = ?
Method POST
Name = MPG RIC
Password = fred 123
Message = This is a test & = ?
SSL TEST FORM

- Note 1: The encoding of & = ? as %26+%3D+%3F (+ is a special character if we used that it would have been encoded)
- Note 2: Although we used GET to send data for some reason PHP has mapped the variables in both GET and POST super-globals (I think this is incorrect!).
- Note 3: SSL TEST FORM displayed hence correct form picked-up

Example 13 - cURL POST
Using example 11 again add the appropriate target page, password and SSL functions:
- curl_setopt($ch, CURLOPT_URL,'https://localhost:446/remote_form.php');
- curl_setopt($ch, CURLOPT_USERPWD, "root:root");
- curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // no verify
Create a new text file in folder C:\curl_1\UniServer\www and name it test13.php add the following content
<?php
$name_val = urlencode('MPG RIC');
$password_val = urlencode('fred 123');
$message_val = urlencode('This is a test & = +');
$str= "Name=".$name_val."&Password=".$password_val."&Message=".$message_val;
print $str;
$ch=curl_init();
curl_setopt($ch, CURLOPT_URL,'https://localhost:446/remote_form.php');
curl_setopt($ch, CURLOPT_USERPWD, "root:root");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // no verify
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $str);
curl_exec($ch);
curl_close($ch);
?>

- First three lines URL encode the values we wish to send.
- Full string $str is assembled into correct format name value pairs.
- Added new URL remember is https and the port must be included
- Added CURLOPT_USERPWD again defaults are root root
- CURLOPT_SSL_VERIFYPEER disabled
- CURLOPT_POST Switches to POST operation
- CURLOPT_POSTFIELDS Informs Curl we are using a value of $str
- This string has been URL encoded.
Note: I have included print $str to show what the encoded string looks like
Test:
- Run both servers
- Type http://localhost/test13.php into your browser
- Result: Shown below

Results:
Name=MPG+RIC&Password=fred+123&Message=This+is+a+test+%26+%3D+%2B
Method GET
Name =
Password =
Message =
Method POST
Name = MPG RIC
Password = fred 123
Message = This is a test & = +
SSL TEST FORM

|
- Note 1: The encoding of & = + as %26+%3D+%2B (+ is a special character hence encoded as %2B)
- Note 2: Results in POST section as expected (no values in GET which is correct).
- Note 3: SSL TEST FORM displayed hence correct form picked-up
