Session value not preserved or not working in dotnetcore webapi
0
Below is my code from startup.cs,
public void ConfigureServices(IServiceCollection services){
services.AddMvc().AddJsonOptions(options =>{
options.SerializerSettings.ContractResolver = new DefaultContractResolver();
});
services.AddDistributedMemoryCache();
services.AddSession(options => {
// Set a short timeout for easy testing.
options.IdleTimeout = TimeSpan.FromSeconds(36000);
options.Cookie.HttpOnly = true;
});
services.AddCors(options => {
options.AddPolicy("CorsPolicy",
builder => builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials());
});
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env{
if (env.IsDevelopment()){
app.UseDeveloperExceptionPage();
}
app.UseStaticFiles();
//app.UseCors("CorsPolicy");
// global cors policy
app.UseCors(x => x
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials());
app.UseSession();
app.UseAuthentication();
app.UseMvc();
}
Below is the code to set and get userid in session:
HttpContext.Session.SetInt32("UserId", user.Id);
int userId = (int)HttpContext.Session.GetInt32("UserId");
I am getting below exception while reading session in a different action from the action where it is set. Any reason why session is not working?

If I get you right. You are settingHttpContext.Session.SetInt32("UserId", user.Id);inmethod A, and thenmethod Ais calling themethod Bwhere you try to useHttpContext.Session.SetInt32("UserId", user.Id);?

No Sebastian. If it is the same action then I don't need session itself right. Session we need for maintaining state between different HTTP requests. I am Setting session in the different controller action and getting it in a different controller action.
