httphandler

问题 I have experienced an error on "The parametrized query '(@blue nvarchar(4000))SELECT blueBallImage FROM CorrespondingBal' expects the parameter '@blue', which was not supplied." I am doing a HttpHandler. I want to retrieve the image from the database.

问题 I am trying to write a asp.net httphandler for handling webdav requests with IIS. I am extending the IHttpHandler interface and implementing the ProcessRequest. public class clsMyHandler : IHttpHandler { public void ProcessRequest(System.Web.HttpContext context) { StreamWriter sw = new StreamWriter(@"C:\requestLog.txt",true); sw.WriteLine("Got a request at " + DateTime.Now.ToString()); sw.Close(); } public bool IsReusable { get { return true; } } } It's a simple handler for my test purpose to

问题 I've set up an STS with WIF and want to expose whether a user is signed in so that an RP can determine if the user is signed in without requiring the user to redirect to the STS and return. If the user is signed in, a different process flow will occur on the RP so it's important to know but not to force the sign-in at this point in the process. My plan was to create a simple generic handler on the STS which, when hit via an HttpWebRequest, returns the output of context.User.Identity

问题 I have an ASP.NET application with 5 .ashx HTTPHandlers that implement IRequiresSessionState or IReadOnlySessionState. Upon calling the first handler I create a variable and store it in the session. When I call the next HttpHandler the variable is not available in the session object. I am use context.Session. I have a global.asax where I retrieve the sessionId. Is there a way to preserve session variables across HttpHandlers or does each Handler get its own session? 回答1: HeartAttack has a

问题 Handler public class Handler2 : IHttpHandler { public void ProcessRequest(HttpContext context) { string id = context.Request.QueryString["Id"]; string constr = System.Configuration.ConfigurationManager .ConnectionStrings["EmployeeDatabase"].ConnectionString; SqlConnection con = new SqlConnection(constr); con.Open(); SqlCommand cmd = new SqlCommand("GetImage", con); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@EmpID", id); //cmd.Parameters.AddWithValue("@Gender"

问题 I have a few http handlers ( IHttpHandler ) in my asp.net web project. Now I want to restrict access to these handlers. For Handler1 I want to allow only POST requests, and for Handler2 I want to allow only GET requests. In my web.config I modified the <httpHandlers> section as shown below, but both handlers still process all verb types. Is there something I've missed? I'm testing it using IIS Express. <httpHandlers> <add verb="POST" path="Handler1.ashx" type="MyNamesapce.Handler1, MyAssembly

问题 I'm trying to run an httphandler (ashx) in a asp.net 4 website. When I call it from Visual Studio integrated server, it returns a 404 error. It works if I call it on the site configured into the local IIS. Someone could help? 回答1: Are you using ASP.NET MVC, or System.Web.Routing? Do you have something like routes.IgnoreRoute("{resource}.ashx/{*pathInfo}"); in your RegisterRoutes() function in your HttpApplication instance? One thing to keep in mind is that the Visual Studio server thingie

问题 There is one in the Views folder. And there is another in the root of the app. I want to register a custom handler and i cant understand where the code should go. I'm running IIS7 in Integrated Mode so I have to add a <handlers> tag to the <system.webServer> but when I'm looking at the web.config at the Views folder I see that it uses a <httpHandlers> under <system.web> tag. So two questions: 1. why are there two web.config files in an mvc application? 2. where and in what way I should

问题 I have created an HttpHandler that I will be using with a jquery-Ajax call. This HttpHandler will access the database and check something related to the currently singed in user . The user is considered signed in by using the Session, with an attribute called user_id . Session["user_id"] = userId; I tried to retrieve this Session in the HttpHandler but that doesn't seem to work. So I thought about sending the user_id as a parameter . var user_id = //Retrieved in some way... $.ajax({ url:
