I have rest api url like this
https://example.com/ProductAPI/api/V1/getproduct.
This api has api_key,username and password.How can I access this api and getproduct details using c#.I tried like this
WebRequest request = WebRequest.Create(#"https://example.com/ProductAPI/api/V1/getproduct");
request.Method = "GET";
request.Headers.Add("api_key","5g13441f-6915-4a34-8a53-bcb4er88b554");
request.Headers["Authorization"] = "Basic" + Convert.ToBase64String(Encoding.Default.GetBytes("admin:123"));
request.ContentLength = 0;
request.ContentType = #"application/json; charset=utf-8";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string jsonResponse = string.Empty;
using (StreamReader sr = new StreamReader(response.GetResponseStream()))
{
jsonResponse = sr.ReadToEnd();
Console.WriteLine(jsonResponse);
Console.ReadLine();
}
But it show 401 unauthorized error.Pls help to solve this
I'm getting data from web service like follow
string serviceUrl = "https://www.mscholid.com/assings/handlqueryrs/myprod.ashx";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(serviceUrl);
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
StreamReader sr = new StreamReader(resp.GetResponseStream());
string result = sr.ReadToEnd();
sr.Close();
var rootResult = XElement.Parse(result);
now I want to put this root result into a session
Session["rootv"] = rootResult;
then I want to retrieve it.
store function should do inside a class
public class NileResult
{
public dynamic nilecruiseFinalData_Images(string selectedID)
{
string serviceUrl = "https://www.mscholid.com/assings/handlqueryrs/myprod.ashx";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(serviceUrl);
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
StreamReader sr = new StreamReader(resp.GetResponseStream());
string result = sr.ReadToEnd();
sr.Close();
var rootResult = XElement.Parse(result);
//in here I want to store in to a session
}
}
how can I do this.
To access the session of the request, you can use:
HttpContext.Current.Session["rootv"] = rootResult;
HttpContext.Current is the current context of the request.
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 used following code to get the access token from code as below
String code = HttpContext.Current.Request["code"];
string redirecturl = HttpContext.Current.Request["url"];
string Url = "https://accounts.google.com/o/oauth2/token";
string grant_type = "authorization_code";
string redirect_uri_encode = UrlEncodeForGoogle(url);
string data = "code={0}&client_id={1}&client_secret={2}&redirect_uri={3}&grant_type={4}&access_type={5}";
HttpWebRequest request = HttpWebRequest.Create(Url) as HttpWebRequest;
string result = null;
request.Method = "POST";
request.KeepAlive = true;
request.ContentType = "application/x-www-form-urlencoded";
string param = string.Format(data, code,configurationInfo.oauthclientid , configurationInfo.oauthclientsecretid, redirect_uri_encode, grant_type, "offline");
var bs = Encoding.UTF8.GetBytes(param);
using (Stream reqStream = request.GetRequestStream())
{
reqStream.Write(bs, 0, bs.Length);
}
using (WebResponse response = request.GetResponse())
{
var sr = new StreamReader(response.GetResponseStream());
result = sr.ReadToEnd();
sr.Close();
}
i am getting response as
The remote server returned an error: (400) Bad Request.
i do not know where i went wrong
waiting for your valuable comments
Google also provides a higher level library for accessing its services. I find it makes it much easier to work with its APIs.

I am working on a program that will log into a website and get certian data. However I am having trouble posting the login parameters and dealing with the cookies, as each time I get a page saying "You have logged out or Session has expired." So clearly I'm doing something wrong with posting the parameters or dealing with the cookies, but don't know which. I have been working on this for a while and just can't get my head around why this is not working correctly.
void Login2(string username, string password)
{
string pageSource;
string formUrl = "https://forUrl.com";
string formParams = string.Format("login={0}&sslProt={1}&pwd={2}&gru={3}", username, "", password, "115237091");
string cookieHeader;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(formUrl);
req.AllowAutoRedirect = false;
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(formParams);
req.ContentLength = bytes.Length;
using (Stream os = req.GetRequestStream())
{
os.Write(bytes, 0, bytes.Length);
}
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
cookieHeader = resp.Headers["Set-cookie"];
string getUrl = "https://Urlbehindform.com";
HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(getUrl);
getRequest.Method = "GET";
getRequest.AllowAutoRedirect = false;
getRequest.Headers.Add("Cookie", cookieHeader);
HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse();
using (StreamReader sr = new StreamReader(getResponse.GetResponseStream()))
{
pageSource = sr.ReadToEnd();
}
Response.Redirect(getUrl);
}
I am getting the cookie when I do the POST and sending it back when I do the GET, but for some reason this doesn't seem to work. At first I thought it was the parameters, but after looking at the issue further using Tamper Data with Firefox the login parameters seem to be working fine. Any help would be great, as I have been working on this for a while and can't wrap my head around it. Thanks!
UPDATE:
After trying out a few suggestions I still can't get this to work. However Upon looking deeper into Data Tamper, It appears that there is a POST with the login parameters, then a GET to a different page and then finally the GET to the page after the login page (The one I'm trying to get to). After some further debugging I actually discovered that my login POST is not working as I thought, As the response header location is showing "/cv/scripts/A028/eng/logErr.asp". Meaning the rest of my code could have been fine all a long, it was that the POST wasn't giving me a valid login. Any Sugguestions as to why I am always getting the login error page? As always thanks for the help.
UPDATE:
After playing around further with Tamper Data is appears that the reason I am unable to get a successful login is that in order have a successful POST of the parameters there needs to be a cookie already obtained. How do I go about doing this?
Use a single CookieContainer for both requests. Then you don't have to copy cookies manually.
I [BMW1] added in a CookieContainer called cookies, but it still not working, Im not sure if im using the CookieContainer the right way. Here is an updated version of my code.
And edited by me [Hans Kesting], see comments with [HK]
void Login2(string username, string password)
{
string pageSource;
string formUrl = "https://server/cv/scripts/A028/eng/logProc.asp?ntry=0&dbg=";
string formParams = string.Format("login={0}&sslProt={1}&pwd={2}&gru={3}", username, "", password, "115237091");
// [HK] create a container for the cookies, where they are added automatically
CookieContainer cookies = new CookieContainer();
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(formUrl);
req.CookieContainer = cookies;
req.AllowAutoRedirect = false;
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(formParams);
req.ContentLength = bytes.Length;
using (Stream os = req.GetRequestStream())
{
os.Write(bytes, 0, bytes.Length);
}
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
// [HK] no need to add cookies "by hand", that will happen automatically
//cookies.Add(resp.Cookies);
string getUrl = "https://server/cv/scripts/A028/eng/home.asp";
HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(getUrl);
// [HK] use the same cookiecontainer as on the first request - correct
getRequest.CookieContainer = cookies;
getRequest.Method = "GET";
getRequest.AllowAutoRedirect = false;
HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse();
// [HK] no need to add cookies, they should be there already
//cookies.Add(getResponse.Cookies);
using (StreamReader sr = new StreamReader(getResponse.GetResponseStream()))
{
pageSource = sr.ReadToEnd();
}
// [HK] no need to add cookies, they should be there already
// cookies.Add(getResponse.Cookies);
Response.Redirect(getUrl);
}
You could use a Cookie aware web client,
public class CookieAwareWebClient : WebClient
{
public CookieContainer CookieContainer { get; set; }
public Uri Uri { get; set; }
public CookieAwareWebClient() : this (new CookieContainer())
{
}
public CookieAwareWebClient(CookieContainer cookies)
{
this.CookieContainer = cookies;
}
protected override WebRequest GetWebRequest(Uri address)
{
WebRequest request = base.GetWebRequest(address);
if (request is HttpWebRequest)
{
(request as HttpWebRequest).CookieContainer = this.CookieContainer;
}
HttpWebRequest httpRequest = (HttpWebRequest) request;
httpRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
return httpRequest;
}
protected override WebResponse GetWebResponse(WebRequest request)
{
WebResponse response = base.GetWebResponse(request);
String setCookieHeader = response.Headers[HttpResponseHeader.SetCookie];
if (setCookieHeader != null)
{
//do something if needed to parse out the cookie.
if (setCookieHeader != null)
{
Cookie cookie = new Cookie(); //create cookie
this.CookieContainer.Add(cookie);
}
}
return response;
}
}
Example usage:
var wc = new CookieAwareWebClient ();
wc.Headers["Content-type"] = "application/x-www-form-urlencoded";
string HtmlResult = wc.UploadString(URI, myParameters);
