Ho creato un progetto API Web mvc4 utilizzando vS2012. Ho utilizzato il seguente tutorial per risolvere la condivisione delle risorse tra le origini, "http://blogs.msdn.com/b/carlosfigueira/archive/2012/07/02/cors-support-in-asp-net-web-api- rc-version.aspx". Funziona correttamente e inserisco i dati dal lato client al server con successo.
Successivamente per l'implementazione dell'autherization nel mio progetto, ho utilizzato il seguente tutorial per implementare OAuth2, "http://community.codesmithtools.com/CodeSmith_Community/b/tdupont/archive/2011/03/18/oauth-2-0-for -mvc-due gambe-implementation.aspx". Questo mi aiuta a ottenere RequestToken dal lato client.
Ma quando inserisco i dati dal lato client, ho ricevuto l'errore "XMLHttpRequest non può caricare http: //. Il campo di intestazione della richiesta Content-Type non è consentito da Access-Control-Allow-Headers."
Il mio codice lato client assomiglia,
function PostLogin() {
var Emp = {};
Emp.UserName = $("#txtUserName").val();
var pass = $("#txtPassword").val();
var hash = $.sha1(RequestToken + pass);
$('#txtPassword').val(hash);
Emp.Password= hash;
Emp.RequestToken=RequestToken;
var createurl = "http://localhost:54/api/Login";
$.ajax({
type: "POST",
url: createurl,
contentType: "application/json; charset=utf-8",
data: JSON.stringify(Emp),
statusCode: {
200: function () {
$("#txtmsg").val("done");
toastr.success('Success.', '');
}
},
error:
function (res) {
toastr.error('Error.', 'sorry either your username of password was incorrect.');
}
});
};
Il mio controller API assomiglia,
[AllowAnonymous]
[HttpPost]
public LoginModelOAuth PostLogin([FromBody]LoginModelOAuth model)
{
var accessResponse = OAuthServiceBase.Instance.AccessToken(model.RequestToken, "User", model.Username, model.Password, model.RememberMe);
if (!accessResponse.Success)
{
OAuthServiceBase.Instance.UnauthorizeToken(model.RequestToken);
var requestResponse = OAuthServiceBase.Instance.RequestToken();
model.ErrorMessage = "Invalid Credentials";
return model;
}
else
{
// to do return accessResponse
return model;
}
}
Il mio file webconfig assomiglia,
