posting saml file using php curl and converting C# code to php - c#

I am trying to httpost saml file in php using curl for sso purposes but the xml contents need to be encoded into byte utf8 and then base64(that's the requirements of the company i am posting to) so they gave me this piece c# and they told me to convert it to php
this is what i get to so far with my php curl saml post:
<?php
$url = "https://my.sandbox.company.com/sso/authenticate.ashx";
$filename = "saml.xml";
$handle = fopen($filename, "r");
$XPost = fread($handle, filesize($filename));
echo urlencode($XPost);
fclose($handle);
$decdata = urlencode($XPost);
$raw = base64_encode($decdata);
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: text/xml"));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 40);
curl_setopt($ch, CURLOPT_POSTFIELDS, $raw);
curl_setopt($ch, CURLOPT_POST, 1);
$result = curl_exec($ch); // run the whole process
if (empty($result)) {
die(curl_error($ch));
curl_close($ch); // close cURL handler
} else {
$info = curl_getinfo($ch);
curl_close($ch); // close cURL handler
if (empty($info['http_code'])) {
die("No HTTP code was returned");
}
else {
echo "The server responded: \n";
echo $info['http_code'] . " " . $http_codes[$info['http_code']];
}
}
echo "RESULT: $result"; //contains response from server
?>
The C# code given
string responseStr = doc.OuterXml;
byte[] base64EncodedBytes = Encoding.UTF8.GetBytes(responseStr);
string returnValue = System.Convert.ToBase64String(base64EncodedBytes);
Please let me know if my code is wrong.
Thank you

How to POST request for authorization token from filemaker API in c#

I am hitting a POST request to a FileMaker API to get an authorization token but its throwing web exception. How can I fix it?
I have tried it in java. Now I am trying it in c# .NET framework 4.6.1
private static void GetToken(string username, string password)
{
try
{
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://exchange.furniflair.com/fmi/data/v1/databases/FurniflairDB/sessions");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
var bytes = Encoding.UTF8.GetBytes("dataapi:Data4me");
string temp = Convert.ToBase64String(bytes);
httpWebRequest.Headers.Add("Authorization", "Basic ZGF0YWFwaTpEYXRhNG1l");
string token;
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Flush();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
token = streamReader.ReadToEnd();
}
}
catch (WebException ex){}
}
I expect the output to be the authorization token in response, but I am getting only exceptions like httpWebException.
If it helps you set the headers correctly, here is an example that works using PHP.
$Post_Json = '{}';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$URL);
curl_setopt($ch, CURLOPT_PORT,443);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_TIMEOUT, 30); //timeout after 30 seconds
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $Post_Json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$result=curl_exec ($ch);
This comes from: https://schwarzsoftware.com.au/blogentry.php?id=19
Also ensure that the Data API is turned on in the FileMaker Admin server console, and enabled for the FileMaker file you are trying to access, and access priviliges enabled for that user in the FileMaker file.

Converting PHP CURL query to C#'s HttpWebRequest

I'm using HttpWebRequest in C# to do a POST to a particular API. The problem is that the system on the other end does not receive the body of the request. More so, when trying to send the request via tools like Postman, I have the same issue. The only thing that seems to work is a PHP implementation, detailed below.
My best guess is that I'm missing some header or another that the PHP sets automatically.
Has anybody encountered a similar problem/does anyone have a clue what I'm missing?
Both implementations below.
<?php
error_reporting(E_ALL);
$url = <<the APIs url>>
$hash = base64_encode('<<username>>:<password>>');
$data = [];
$username = <<username>>
$password =<password>>
$data = array(array(
"id" => "9999999",
"status" => 1,
<<rest of the formated data>>
));
$requestData = array(
'data' => $data,
'hash' => $hash
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($requestData));
$result = curl_exec($ch);
// $result = json_decode($result, true);
curl_close($ch);
die('done :'.$result);
?>
And here the C# implementation:
var httpWebRequest = (HttpWebRequest)WebRequest.Create(this.api_url);
httpWebRequest.ContentType = "application/x-www-form-urlencoded";
httpWebRequest.Method = "POST";
httpWebRequest.KeepAlive = true;
httpWebRequest.Date = DateTime.Now.Date;
httpWebRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";
httpWebRequest.Headers.Add("Authorization", "Basic " + Base64Encode(userName + ":" + password));
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
}
tring requestResult = null;
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
requestResult= streamReader.ReadToEnd();
}
If you are posting JSON data, you should set the content type to application/json.

Send Parameter HttpWebRequest return XML

Good morning,
I am trying to connect to a payment gateway which sends you a post parameters using HttpWebRequest.
The code that has done in the api is php but I need in C#.
function send_trans($url, $postData) {
$headers = array( 'Connection: Keep-Alive',
'Content-Type: application/x-www-form-urlencoded');
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko
/20080311 Firefox/2.0.0.13');
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 60);
curl_setopt($ch, CURLOPT_TIMEOUT, 40); // timeout en 40 segundos
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$xml = curl_exec($ch);
curl_close($ch);
return ($xml);
}
have tried it with the following code.
  
 
public static string HttpPostRequest (string url, Dictionary <string, string> postParameters)
        {
            string postData = "";
            foreach (string key in postParameters.Keys)
            {
                postData + = key + "=" + postParameters [key] + "&";
            }
            HttpWebRequest myHttpWebRequest = (HttpWebRequest) HttpWebRequest.Create (url);
            myHttpWebRequest.Method = "POST";
            byte [] data = Encoding.ASCII.GetBytes (postData);
            myHttpWebRequest.ContentType = "application / x-www-form-urlencoded";
            myHttpWebRequest.ContentLength = data.Length;
            Stream requestStream = myHttpWebRequest.GetRequestStream ();
            requestStream.Write (data, 0, data.Length);
            requestStream.Close ();
            HttpWebResponse myHttpWebResponse = (HttpWebResponse) myHttpWebRequest.GetResponse ();
            Stream responseStream = myHttpWebResponse.GetResponseStream ();
            StreamReader myStreamReader = new StreamReader (responseStream, Encoding.Default);
            string pageContent = myStreamReader.ReadToEnd ();
            myStreamReader.Close ();
            responseStream.Close ();
            myHttpWebResponse.Close ();
            return pageContent;
        }
the error it gives me is in the line of Stream responseStream = myHttpWebResponse.GetResponseStream (), I have tried with other code and it is always the same error in GetResponseStream.

How i can acheive this in c# to post xml requrest?
You will have to create object, uri is your url and than post it.
xmldata is your xml file
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(uri);
byte[] postDataBytes = Encoding.ASCII.GetBytes(xmldata);
req.Method = "POST";
req.ContentLength = postDataBytes.Length;
Stream requestStream = req.GetRequestStream();
requestStream.Write(postDataBytes, 0, postDataBytes.Length);
requestStream.Close();
