My problem is when I use new webclient to send url to the WebService it asks me to login, and after searched about this issue I found that you need to save cookies but its not working with me.
And upon your request this is the full code
namespace PhoneApp8
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
// Sample code to localize the ApplicationBar
//BuildLocalizedApplicationBar();

string baseuri = "http://IP in the comment/vertexweb10/webservice.svc/login?username=%22user15650%22&password=%22898k%22";
CookieAwareWebClient wc = new CookieAwareWebClient();
wc.DownloadStringCompleted += ParseProducts_AsJson;

if (UserIdVal == -1 || UserIdVal == -207)
MessageBox.Show("Invalid username or password");
else if (UserIdVal == -231)
{
MessageBox.Show("You must have at least one account");
}
else if (webResponse == null || webResponse == "" || UserIdVal < 0)
{
MessageBox.Show("Error while login.Please try later");
}
else if (UserIdVal > 0)
{
string baseuri1 = "http://IP in the comment/vertexweb10/webservice.svc/getallsymbols?AccountID=1122336675";
CookieAwareWebClient wc1 = new CookieAwareWebClient();
wc1.DownloadStringCompleted += ParseProducts_AsJson1;

class CookieAwareWebClient : WebClient
{
[System.Security.SecuritySafeCritical]
private CookieContainer cookie;
public CookieContainer Cookie { get { return cookie; } }
public CookieAwareWebClient()
{
cookie = new CookieContainer();
}
public CookieAwareWebClient(CookieContainer givenContainer)
{
cookie = givenContainer;
}
}
}
}
I think the error is in the cookie container, the last cookieaware i use (i have tried more than 10 cookie container codes)
回答1:
This is the code, what it does is it calls the first Url and get response if response is good, it copies the cookie to sessionCookie variable. and uses that in the second call
Declare sessioncookie some where in the same page
public static CookieContainer sessionCookie;
And Copy this in your button click
public static async Task<string> SendRequestGetResponse()
{
try
{
var postRequest = (HttpWebRequest)WebRequest.Create("http://74.54.46.178/vertexweb10/webservice.svc/login?username=%22user15650%22&password=%22898k%22");
postRequest.Method = "GET";
if (sessionCookie == null)
{
postRequest.CookieContainer = new CookieContainer();
}
else
{
postRequest.CookieContainer = sessionCookie;
}
HttpWebResponse postResponse = (HttpWebResponse)await postRequest.GetResponseAsync();
if (postResponse != null)
{
var postResponseStream = postResponse.GetResponseStream();
var postStreamReader = new StreamReader(postResponseStream);
string response = await postStreamReader.ReadToEndAsync();
if (sessionCookie == null)
{
sessionCookie = postRequest.CookieContainer;
}
}
var postRequest1 = (HttpWebRequest)WebRequest.Create("http://74.54.46.178/vertexweb10/webservice.svc/getallsymbols?AccountID=1122336675");
postRequest1.Method = "GET";
if (sessionCookie == null)
{
postRequest1.CookieContainer = new CookieContainer();
}
else
{
postRequest1.CookieContainer = sessionCookie;
}
HttpWebResponse postResponse1 = (HttpWebResponse)await postRequest1.GetResponseAsync();
if (postResponse1 != null)
{
var postResponseStream1 = postResponse1.GetResponseStream();
var postStreamReader1 = new StreamReader(postResponseStream1);
string response1 = await postStreamReader1.ReadToEndAsync();
}
}
}
回答2:
I have solved my problem using
request.CookieContainer = cookieJar;
then i use the same cookieJar on the second request
var request = HttpWebRequest.Create(new Uri("http://x.x.x.x/vertexweb10/webservice.svc/getallsymbols?AccountID=1122336675")) as HttpWebRequest;
request.Method = "GET";
request.CookieContainer = cookieJar;
request.BeginGetResponse(ar =>
{
HttpWebRequest req2 = (HttpWebRequest)ar.AsyncState;
using (var response = (HttpWebResponse)req2.EndGetResponse(ar))
{
using (Stream stream = response.GetResponseStream())
{
using (var reader = new StreamReader(stream))
{
//the code you need
}
}
}
}, request);
