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();

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.
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.
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.
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
I have to make a post to a third party https url to get data procesed and sent back. And all I have as an example is this:
$signature= foo_string;
$data_to_post = json_dictionary;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $base_url);
curl_setopt($ch, CURLOPT_USERPWD, "$user:$password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER,array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_HTTPHEADER,array("JSON-Signature: $signature"));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_to_post);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
As we work with ASP .NET C# 2.0, I have to port this, but I get always a not autenticated error.
Here is what I'm doing:
HttpWebRequest q = (HttpWebRequest)WebRequest.Create(Host + ":" + Port);
ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(new interhanse().AcceptAllCertifications);
q.Method = "POST";
q.Headers.Add("JSON-Signature:" + GetSignature(data));
q.ContentType = "application/json";
q.UseDefaultCredentials = false;
q.Credentials = new NetworkCredential(user,pwd, Host);
byte[] buffer = UTF8Encoding.UTF8.GetBytes(data);
q.ContentLength = data.Length;
Stream oStream = q.GetRequestStream();
StreamWriter oWriter = new StreamWriter(oStream);
oWriter.Write(buffer);
oWriter.Close();
HttpWebResponse reps = q.GetResponse() as HttpWebResponse;
I've read all SO questions I can find about this, but I don't get any improvements. Thanks in advance!
Well, one thing you're doing wrong is assuming that the length in bytes is the same as the length in characters. You should use buffer.Length for the content length. You're also calling StreamWriter.Write with a byte array. You shouldn't do that - you should just use the stream, as you've already done the encoding:
byte[] buffer = Encoding.UTF8.GetBytes(data);
q.ContentLength = buffer.Length;
using (Stream stream = q.GetRequestStream())
{
stream.Write(buffer, 0, buffer.Length);
}
Now, that won't solve the authentication issue. You may find that just setting PreAuthenticate solves that though:
q.PreAuthenticate = true;
If that doesn't work, I suggest you run WireShark and look at the differences between the request through Curl and the request from .NET.
I think you should not supply the host in the authentication...
q.Credentials = new NetworkCredential(user,pwd);
Which would be something like:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Host + ":" + Port);
ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(new interhanse().AcceptAllCertifications);
request.Method = "POST";
request.Headers.Add("JSON-Signature:" + GetSignature(data));
request.ContentType = "application/json";
request.UseDefaultCredentials = false;
request.Credentials = new NetworkCredential(user, pwd);
byte[] buffer = UTF8Encoding.UTF8.GetBytes(data);
request.ContentLength = buffer.Length;
using (Stream oStream = request.GetRequestStream()) {
oStream.Write(buffer, 0, buffer.Length);
}
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) {
// load data from response here
}
Also you should avoid assigning the service point validation delegate on each request, this may slow down the requests increasingly because the validation is performed multiple times, and it's also kind of a memory leak.
curl_setopt($ch, CURLOPT_USERPWD, "$user:$password");
Here is how you add that CURLOPT_USERPWD in Asp.Net:
private async Task<string> Execute(string url, string query, string user, string pasword)
{
HttpClient httpClient = new HttpClient();
var baseUri = new Uri(url, UriKind.Absolute); // e.g. http://somedomain.com/endpoint
Uri request = new Uri(baseUri, query); // with query e.g. http://somedomain.com/endpoint?arg1=xyz&arg2=abc
// Add a new Request Message
HttpRequestMessage requestMessage = new HttpRequestMessage(HttpMethod.Get, request);
// add headers -> CURLOPT_USERPWD equivalent
var encodedStr = Convert.ToBase64String(Encoding.Default.GetBytes(string.Format("{0}:{1}", user, password)));
var authorizationKey = "Basic" + " " + encodedStr; // Note: Basic case sensitive
requestMessage.Headers.Add("Authorization", authorizationKey);
// if POST - do this instead
// content
//HttpContent content = new StringContent(jsonContent); // string jsonContent i.e. JsonConvert.SerializeObject(YourObject);
//requestMessage.Content = content;
//requestMessage.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
// execute
HttpResponseMessage responseMessage = await httpClient.SendAsync(requestMessage);
var responseString = await responseMessage.Content.ReadAsStringAsync(); // reads it as string;
// if json and you need to convert to an object do this
// var myresponse = JsonConvert.DeserializeObject<YourMappedObject>(responseString);
return responseString;
}
