I have been doing some Google searches and only getting partial successful on this topic. I was wondering if someone could suggest an example of doing an HTTP POST using C# to send XML to HTTP service.
I have a asmx web service that extracts data from database and I save that data to XML document. Now I have to send that XML document using SOAP protocol to HTTP service.
I have this part of code for connectig to service
WebRequest myReq = WebRequest.Create("https://WEB_URL");
System.Net.ServicePointManager.CertificatePolicy = new CertificatePolicyClass();
string username = "SOMETHING";
string password = "ELSE";
string usernamePassword = username + ":" + password;
CredentialCache mycache = new CredentialCache();
mycache.Add(new Uri("https://WEB_URL"), "Basic", new NetworkCredential(username, password));
myReq.Credentials = mycache;
myReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword)));
WebResponse wr = myReq.GetResponse();
Stream receiveStream = wr.GetResponseStream();
StreamReader reader = new StreamReader(receiveStream, Encoding.UTF8);
string content = reader.ReadToEnd();
So does anybody have a code to send XML document to http service, this part I don't know how to write, I don't know am I on the write trace, I belive it has to go somethig like this
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
So plese can somebody help me! THANKS!
Here is something I get, hope it's useful to you:
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("https://WEB_URL");
myReq.Method = "POST";
myReq.ContentType = "text/xml";
myReq.Timeout = 30000;
myReq.Headers.Add("SOAPAction", ":\"#save\"");
byte[] PostData = Encoding.UTF8.GetBytes(xmlDocument);
myReq.ContentLength = PostData.Length;
using (Stream requestStream = myReq.GetRequestStream())
{
requestStream.Write(PostData, 0, PostData.Length);
}
HttpWebResponse response = (HttpWebResponse)myReq.GetResponse();
string soap =
#"<?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""

<soap:Body>
<Register xmlns=""http://tempuri.org/"">
<id>123</id>
<data1>string</data1>
</Register>
</soap:Body>
</soap:Envelope>";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost/WebServices/CustomerWebService.asmx");
req.Headers.Add("SOAPAction"http://tempuri.org/Register\"");
req.ContentType = "text/xml;charset=\"utf-8\"";
req.Accept = "text/xml";
req.Method = "POST";
using (Stream stm = req.GetRequestStream())
{
using (StreamWriter stmw = new StreamWriter(stm))
{
stmw.Write(soap);
}
}
WebResponse response = req.GetResponse();
Stream responseStream = response.GetResponseStream();

I am using postmates Delivery Quote API for the last one year, And it is working good by the time when I checked.
But now it seems to be not working
It is throwing an exception with an HTML text with some enable cookies and captcha
I can't understand if i am missing some updates from postmates
Here is my coding
HttpWebRequest req = WebRequest.Create(new Uri("https://api.postmates.com/v1/customers/" + PostmatesCustomerId + "/delivery_quotes")) as HttpWebRequest;
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.Headers.Add("Authorization", "Basic " + Base64string);
StringBuilder paramz = new StringBuilder();
paramz.Append("pickup_address=" + PickUpAddress + "&dropoff_address=" + DeliveryAddress);
byte[] formData =
UTF8Encoding.UTF8.GetBytes(paramz.ToString());
req.ContentLength = formData.Length;
// Send the request:
using (Stream post = req.GetRequestStream())
{
post.Write(formData, 0, formData.Length);
}
string responseString = null;
using (HttpWebResponse resp = req.GetResponse()
as HttpWebResponse)
{
StreamReader reader =
new StreamReader(resp.GetResponseStream());
responseString = reader.ReadToEnd();
}
If you're outside of the US, try using a VPN as a workaround to test.
I am bit stuck here, trying to Integrate ALM using Rest API from C# Window application . But failed at the first step that is authentication .
Here is my Authentication call :
public void auth(string url, string xml)
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
byte[] requestBytes = System.Text.Encoding.UTF8.GetBytes(xml.ToString());
req.Method = "POST";
req.ContentType = "application/xml";
req.Accept = "application/xml";
req.KeepAlive = true;
req.AllowAutoRedirect = true;
req.ContentLength = requestBytes.Length;
Stream requestStream = req.GetRequestStream();
requestStream.Write(requestBytes, 0, requestBytes.Length);
requestStream.Close();
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
StreamReader sr = new StreamReader(res.GetResponseStream(), System.Text.Encoding.Default);
backstr = sr.ReadToEnd();
myheader = res.Headers.Get("Set-Cookie");
sr.Close();
res.Close();
}
which i am calling like this :
try
{
// my creds, server details
string server_ = #"https://MyAlmUrl";
string user_ = "username";
string password_ = "password";
string xmll = "<?xml version='1.0' encoding='utf-8'?><alm-authentication><user>" + user_ + "</user><password>" + password_ + "</password></alm-authentication>";
rest.auth(server_ + "/authentication-point/authenticate", xmll);
}
No matter what ever i do It lands into : 401 unauthorized error.
I do have a valid credentials as i am able to login using the web with same credentials .
Some one help me out, what i am doing wrong , As This ALM and using Rest API , both are new to me .
Try this :
HttpWebRequest myauthrequest = (HttpWebRequest)WebRequest.Create("http://{qcserver}/qcbin/authentication-point/alm-authenticate");
string AuthenticationXML = #"<alm-authentication>
<user>{qcserver-username}</user>
<password>{qcserver-pwd}</password>
</alm-authentication>";
byte[] Requestbytes = Encoding.UTF8.GetBytes(AuthenticationXML);
myauthrequest.Method = "POST";
myauthrequest.ContentType = "application/xml";
myauthrequest.ContentLength = Requestbytes.Length;
myauthrequest.Accept = "application/xml";
Stream RequestStr = myauthrequest.GetRequestStream();
RequestStr.Write(Requestbytes, 0, Requestbytes.Length);
RequestStr.Close();
HttpWebResponse myauthres = (HttpWebResponse)myauthrequest.GetResponse();
var AuthenticationCookie = myauthres.Headers.Get("Set-Cookie");
//request to get all domains in ALM
HttpWebRequest domainreq = (HttpWebRequest)WebRequest.Create("http://{qcserver}/qcbin/rest/domains/");
domainreq.Method = "GET";
domainreq.ContentType = "application/xml";
domainreq.Accept = "application/xml";
domainreq.Headers.Set(HttpRequestHeader.Cookie, AuthenticationCookie);
HttpWebResponse domainres= (HttpWebResponse)domainreq.GetResponse();
Stream RStream = domainres.GetResponseStream();
XDocument doc = XDocument.Load(RStream);
//request to dowmload a particular attachement assigned to a test case
HttpWebRequest attachmentreq = (HttpWebRequest)WebRequest.Create("http://{qcserver}/qcbin/rest/domains/{domainname}/project/{projectname}/tests/{testid}/attachments/file.xls");
attachmentreq.Method = "GET";
attachmentreq.ContentType = "application/xml";
attachmentreq.Accept = "application/octet-stream";
attachmentreq.Headers.Set(HttpRequestHeader.Cookie, AuthenticationCookie);
HttpWebResponse attachmentres= (HttpWebResponse)attachmentreq.GetResponse();
Stream RStream = attachmentres.GetResponseStream();
var fileStream = File.Create("C:\\PathToFile");
RStream.InputStream.CopyTo(fileStream);
fileStream.Close();
I am trying to write a YouTube app for windows phone, and I stumbled upon some problems on the authentication side. For some reason the following code is not working properly,
string url = "https://accounts.google.com/o/oauth2/token?";
string postData = "code=" + str + "&client_id=*********.apps.googleusercontent.com&client_secret=*******&grant_type=authorization_code";
HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create(url);
byte[] data = Encoding.Unicode.GetBytes(postData);
httpWReq.Method = "POST";
httpWReq.ContentType = "application/x-www-form-urlencoded";
using (Stream stream =await httpWReq.GetRequestStreamAsync())
stream.Write(data, 0, data.Length);
HttpWebResponse response =(HttpWebResponse)(await httpWReq.GetResponseAsync());
string responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
I am fairly new to HttpWebRequest so probably I missed something, although I am getting a response:
Bad Request
To be specific it says that grant_type is missing although I am pretty sure that it is not, I did everything according to the documentation. What am I doing wrong ?
This will probably fix it
parameters.Append("code=" + str);
parameters.Append("&client_id=*****.apps.googleusercontent.com");
parameters.Append("&client_secret=*****");
parameters.Append("&redirect_uri=urn:ietf:wg:oauth:2.0:oob:auto");
parameters.Append("&grant_type=authorization_code");
string p_params = parameters.ToString();
byte[] p_data_params = Encoding.UTF8.GetBytes(p_params);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://accounts.google.com/o/oauth2/token");
request.Accept = "application/json";
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
Stream dataStream = await request.GetRequestStreamAsync();
dataStream.Write(p_data_params, 0, p_data_params.Length);
dataStream.Dispose();
HttpWebResponse response = (HttpWebResponse)await request.GetResponseAsync();
Stream responseStream = response.GetResponseStream();
StreamReader readStream = new StreamReader(responseStream, Encoding.UTF8);
string result = readStream.ReadToEnd();
Works fine for me.
/*WebClient client = new WebClient();

The only approach that seems to work for me is using HttpWebRequest. I found the answer here: .Net Google OAuth token WebRequest Bad Request Protocol Error If anyone knows of a way to get the Web Client implementation working please let me know! Thanks.
I'am trying to use example api call in below link please check link
http://sendloop.com/help/article/api-001/getting-started
My account is "code5" so i tried 2 codes to get systemDate.
1. Code
var request = WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json");
request.ContentType = "application/json; charset=utf-8";
string text;
var response = (HttpWebResponse)request.GetResponse();
using (var sr = new StreamReader(response.GetResponseStream()))
{
text = sr.ReadToEnd();
}
2.Code
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json");
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json";
But i don't know that i use correctly api by above codes ?
When i use above codes i don't see any data or anything.
How can i get and post api to Sendloop.And how can i use api by using WebRequest ?
I will use api first time in .net so
any help will be appreciated.
Thanks.
It looks like you need to post your API key to the endpoint when making requests. Otherwise, you will not be authenticated and it will return an empty response.
To send a POST request, you will need to do something like this:
var request = WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json");
request.ContentType = "application/json; charset=utf-8";
string postData = "APIKey=xxxx-xxxxx-xxxxx-xxxxx-xxxxx";
request.Method = "POST";
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes(postData);
request.ContentLength = data.Length;
Stream newStream = request.GetRequestStream(); //open connection
newStream.Write(data, 0, data.Length); // Send the data.
newStream.Close();
string text;
var response = (HttpWebResponse)request.GetResponse();
using (var sr = new StreamReader(response.GetResponseStream()))
{
text = sr.ReadToEnd();
}
string userAuthenticationURI =
"https://maps.googleapis.com/maps/api/distancematrix/json?origins="+ originZip +
"&destinations="+ DestinationZip + "&units=imperial&language=en-
EN&sensor=false&key=Your API Key";
if (!string.IsNullOrEmpty(userAuthenticationURI))
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(userAuthenticationURI);
request.Method = "GET";
request.ContentType = "application/json";
WebResponse response = request.GetResponse();
var responseString = new
StreamReader(response.GetResponseStream()).ReadToEnd();
dynamic obj = JsonConvert.DeserializeObject(responseString);
}
