Connecting To Web Services through Xamarin

I am new to Xamarin and am trying to connect to my client web services whose address is http://smartasset-utw.malaysiaairports.com.my:5010/service1.asmx?op=GetUserLogin. This is used to authenticate logins. The code that I have used is below.
var httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("text/xml"));
httpClient.DefaultRequestHeaders.Add("SOAPAction", "http://smartasset-utw.malaysiaairports.com.my:5010/service1.asmx?WSDL");
string wUser = "XXXXX";
string wPassword = "xxxxxxxx";
string soapstr = string.Format(#"<?xml version=""1.0"" encoding=""utf-8""?>
<soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
<soap:Body>
<GetUserLogin xmlns=""http://tempuri.org/"">
<userName>{0}</userName>
<password>{1}</password>
</GetUserLogin>
</soap:Body>
</soap:Envelope>", wUser, wPassword);
var response = httpClient.PostAsync("http://smartasset-utw.malaysiaairports.com.my:5010/service1.asmx?WSDL", new StringContent(soapstr, Encoding.UTF8, "text/xml")).Result;
var content = response.Content.ReadAsStringAsync().Result;
Unfortunately, the response that I get is:
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultcode>soap:Client</faultcode><faultstring>Server did not recognize the value of HTTP Header SOAPAction: http://smartasset-utw.malaysiaairports.com.my:5010/service1.asmx.</faultstring><detail /></soap:Fault></soap:Body></soap:Envelope>
Any help would be appreciated,
Thanks

ContentMD5Missing - Amazon Webservice

I'm trying to post to Feed -> SubmitFeed.
However the exception I receive back is:
you must pass a Content-MD5 HTTP header for your feed so we can be
sure it was not corrupted (e.g. dropped a 0 from a price) before we
process it
What I don't understand is the documentation states that it is optional so unsure why I am receiving this. Plus I am actually passing something through.
XML
<?xml version="1.0" encoding="UTF-8" ?>
- <AmazonEnvelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" schemaLocation="amzn-base.xsd">

How I attach the Body/Header
var request = Helper.CreateWebRequest(xmlRequest.Config, genericparameters, signatureHelpers);
request.Headers.Add("x-amazon-user-agent", amazonHostAgent);
request.Method = "POST";
request.ContentType = amazonConfig.ContentType;
request.Timeout = 50000;
Helper.AddXmlDocumentToRequest(xmlRequest.XmlDocument.InnerXml, request);
public static void AddXmlDocumentToRequest(string xmlDocument, WebRequest request)
{
var bytes = Encoding.ASCII.GetBytes(xmlDocument);
request.ContentLength = bytes.Length;
var requestStream = request.GetRequestStream();
request.Headers.Add("Content-MD5", GetMd5HashFromStream(bytes));
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
}
public static string GetMd5HashFromStream(byte[] bytes)
{
using (var md5 = MD5.Create())
{
var hash = md5.ComputeHash(bytes);
return Convert.ToBase64String(hash);
}
}
Within the request when I drill down to Headers I have the following:
{x-amazon-user-agent: MWSApplication/1.0 (Language=c#)
Content-Type: text/xml
Host: mws.amazonservices.co.uk
Content-Length: 478
Expect: 100-continue
Content-MD5: 1xLxj5Y+WVsAVR9BbQfzQA==
}
When I run the xml through scratchpad it returns the same Content-MD5: 1xLxj5Y+WVsAVR9BbQfzQA==
Am I doing something wrong?
Thanks,
Clare

This might not be the answer for everyone however it was for me and if it helps one other person I will be happy :-)
Me being very stupid, added the header after the streaming, this is not what you should be doing.
Create the URL
Add headers and other elements i.e.
request.ContentType
Stream documents (body of request) if required
request.GetResponse.
Thanks,
Clare

How to obtain FedAuth Cookie From On Premise SharePoint 2013 and ADFS

I have a test environment set up using windows server 2012 R2, ADFS and sharepoint 2013. I can successfully login to Sharepoint 2013 using ADFS as the Claims Identity provider. Now I am trying to login to Sharepoint from my C# application.
I am able to request the saml assertion token from adfs using the following.
Now i would like help with posting the saml token to SharePoint and retrieve a FedAuth cookie so I can passively login to SharePoint 2013 and upload a document from a C# application.
When I call the last method PostSharePointSTS() No Cookies are set.
most of the code has been the help of Leandro Boffi

Why don't you just use the standard SharePoint CSOM library to do whatever you want in SharePoint? CSOM does all the necessary ADFS interaction on behalf of the user on the SharePoint side automatically.

Soap Request in C#

I've got a soap request I've written in http & javascript but I cannot seem to convert it into C# correctly.
Original: (Works)
<button onclick="doStuff()" type="submit">Send</button>
<textarea name="REQUEST_DATA" cols=120 rows=17 >

</soap:Envelope>
</textarea>
<script language="javascript">

var xmlhttp = new ActiveXObject("Msxml2.XMLHTTP.3.0");

At the moment when I run the C# code I get an internal 500 server error, so what have I done wrong?

I have tried to reproduce your problem. Currently i am not able to create your request but i have generated local request with your data.
One thing I came to know is if I remove double quotes(") around the utf-8 and it worked fine.
Just pass charset=utf-8 instead of charset=\"utf-8\""
I am not sure it will work for you or not.

Is there a reason you can't just use Visual Studio's built in support for SOAP web services?
You can add a service reference or a web reference (depending on whch framework version you are targeting).
Then you can just use the proxy class that VS creates for you.
There's no advantage to writing all of the HTTP code yourself. Actually, there's a big disadvantage, in that you are aren't getting proper data types from the WSDL of your SOAP service.

Call PHP based webservice

I'm working on a asp.net webapplication, build in C#. I have to implement a third party web-service that is created using PHP. It is a very simple service containing only one function. I added the service reference using the wsdl, so far so good.
When I call the web-service function with the correct parameters it always returns null. I started troubleshooting with SoapUI. I captured the soap message from the application and pasted it in SoapUI, executed it and it returned the correct message. Using Fiddler I discovered something weird in the response from the web-service as shown in the raw output:
HTTP/1.1 200 OK

The header is displayed correctly. The response is encoded and needs to be decoded. Both SoapUI and Fiddler are able to decode the response, but the proxy class can't and returns null.
How can I overcome this problem? Any help is greatly appreciated!
EDIT:
The way the service is called:
LisenceServiceFR.ServiceRegistration_PortTypeClient client = new LisenceServiceFR.ServiceRegistration_PortTypeClient();
LisenceServiceFR.aVehicleInfo info = client.getVehicleInfo("xxx", "xxx", licensePlate, "localhost");
Edit 2:
The response XML from Fiddler.
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://services.audaconfr.com/ServiceRegistration.wsdl">
<SOAP-ENV:Body>
<SOAP-ENV:getVehicleInfoResponse>
<aVehicle>
<ns1:errorCode>200</ns1:errorCode>
<ns1:errorMessage>Success</ns1:errorMessage>
<ns1:vehicleXml>
<vehicule>
<carr>MONOSPACE COMPACT</carr>

<!-- etc -->
</vehicule>
</ns1:vehicleXml>
</aVehicle>
</SOAP-ENV:getVehicleInfoResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

I ended up using HttpWebRequest to call the webservice:
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.InnerXml = xml;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(endPoint);
req.Timeout = 100000000;
if (proxy != null)
req.Proxy = new WebProxy(proxy, true);
req.Headers.Add("SOAPAction", "");
req.ContentType = "application/soap+xml;charset=\"utf-8\"";
req.Accept = "application/x-www-form-urlencoded";
req.Method = "POST";
Stream stm = req.GetRequestStream();
doc.Save(stm);
stm.Close();
WebResponse resp = req.GetResponse();
stm = resp.GetResponseStream();
StreamReader r = new StreamReader(stm);
string responseData = r.ReadToEnd();
XDocument response = XDocument.Parse(responseData);
/* extract data from response */
It was not the solution I was looking for, but is works like a charm.
