问题 I have an ASP.NET OData site that has the following in the WebApiConfig file: config.Filters.Add(new AuthorizeAttribute()) This forces all callers to authenticate before calling any of the controllers. Unfortunately, this also forces user authentication to access the "$metadata" url. I need to globally force authentication for all controller access while also allowing anonymous access the the "$metadata" url. 回答1: Create a custom filter that derives from AuthorizeAttribute and override the

问题 I am using the standard ASP.net OWIN OAuth middleware system to authenticate local users with Bearer tokens. What I would like to do is is hand out role-based tokens for the same user account. eg. OAuth TokenA => General User Privileges UserA -> OAuth TokenB => Admin User Privileges Is this supported in any way? 回答1: I was able to solve this using the following method - //ensure the token is a User role token only identity.AddClaim(new Claim(ClaimTypes.Role, "User")); Where 'identity' is an

问题 I'm building an offline web app that uses the path string for client-side URLs. There are several (attribute-based) routes that map to dedicated controllers for resources, API calls, etc.. For example: /myapp/api/... /myapp/resources/... I then want all requests that do not match one of these patterns to be routed to my bootstrap HTML page, which I currently serve via a dedicated controller. So, for example, the following requests need to end up at the bootstrap HTML page: /myapp/customers/..

问题 I am researching my first RESTful API project to interact with the automation side of our ERP system. I am planning a SPA like here The simple web page is to provide users with a list of purchase requisitions they must approve or decline. The app will retrieve the data from a SQL Server view into a collection. As the user approves or declines the requisition this is recorded in the object and when the User presses 'Update ERP' the app will build a XML list of the collection and using a SQL

问题 I wrote some WebAPI controllers using WebAPI for DotNetNuke 7.0 using this method Everything worked great. Today I upgraded DNN to 7.2.1 and upgraded my projects to ASP.NET Web API2 and my services on my local machine are now not working - they return "HTTP Error 404.0 - Not Found". I think it is something to do with IIS and extensionless URLs - I checked IIS and DesktopModules is not an application as suggested here. I tried Fiddler and F12 Debugging tools and the message is giving no clues

问题 Imagine the following: client app, which no one has control over, calls Web API methods but each of these methods ends in extensions such as : /api/{controller}/{method}.ab How is it possible to configure the ASP.NET web API, for a specific controller, to allow extensions for the method being called but also allow the existing default controllers to continue working? For instance if we have a method call GetCustomer , the client app will call GetCustomer.ab but want that call to be routed to

问题 I have this scenario where I have a WebApi and an endpoint that when triggered does a lot of work (around 2-5min). It is a POST endpoint with side effects and I would like to limit the execution so that if 2 requests are sent to this endpoint (should not happen, but better safe than sorry), one of them will have to wait in order to avoid race conditions. I first tried to use a simple static lock inside the controller like this: lock (_lockObj) { var results = await _service
