I am trying to fetch Google calendar event in the Windows store app
(C#). As Google library is not compatible with Windows store app,
trying for alternative. Below is my code. I am getting error as below.
Plz help to resolve and fetch Google calendar events .
An error occurred while sending the request. The request was aborted:
Could not create SSL/TLS secure channel.
And sometime we get
Response status code does not indicate success: 401 (Authorization
required).
try
{
//Calendar event fetching
var objURLAuth = string.Format("http://www.google.com/
accounts/ClientLogin?service=cl&Email={0}&Passwd={1}",
Uri.EscapeDataString(txtAccount.Text.Trim()),
Uri.EscapeDataString(txtPassword.Password.Trim()));
HttpClient objHttpClient = new HttpClient();
HttpResponseMessage objResponseAuth;
objResponseAuth = await
objHttpClient.GetAsync(objURLAuth);
string sResponseAuthText = await
objResponseAuth.Content.ReadAsStringAsync();
if (sResponseAuthText != "Error=BadAuthentication\n")
{
//string SID =
sResponseAuthText.Substring((sResponseAuthText.IndexOf("SID=") + 4),
(sResponseAuthText.IndexOf("\n") - 4));//extracting SID
string Auth =
sResponseAuthText.Substring((sResponseAuthText.IndexOf("Auth=") + 5),
(sResponseAuthText.Length - (sResponseAuthText.IndexOf("Auth=") + 5))
- 1);//extracting Auth
HttpClient objHttpClientzzz;
objHttpClientzzz = objHttpClient;
objHttpClientzzz.DefaultRequestHeaders.Add("Authorization",
"GoogleLogin auth=" + Auth);
HttpResponseMessage ObjCalHttpReponse = await
objHttpClientzzz.GetAsync("https://www.google.com/calendar/feeds/
default/private/full");
ObjCalHttpReponse.EnsureSuccessStatusCode();
string html = await
ObjCalHttpReponse.Content.ReadAsStringAsync();
string sStatusCode =
ObjCalHttpReponse.StatusCode.ToString();
string sCalResponseText = await
ObjCalHttpReponse.Content.ReadAsStringAsync();
var md = new MessageDialog("Events: " +
sCalResponseText);
md.Commands.Add(new UICommand("OK",
(UICommandInvokedHandler) =>
{
}));
md.ShowAsync();
}
}
catch (Exception Ex)
{
//if (bIsDebug == true)
{
var md = new MessageDialog("Error: " +
Ex.Message.ToString());
md.Commands.Add(new UICommand("OK",
(UICommandInvokedHandler) =>
{
}));
md.ShowAsync();
}
}
