I'm implementing a Web API interface to support some fairly complex queries to run against it and have run up against an issue with the maximum request URI length.

How do I serialize an IdentityUser reference in Web API 2.2?

由 心已入冬 提交于 2019-12-04 05:09:28
问题 The Visual Studio "Web API" project template includes endpoints for handling registration, authentication, and authorization of users. In a production application, however, users will typically be associated with other Entities as well, such as: public class Post { public Post() {}; public int Id { get; set; } public ApplicationUser User { get; set; } } In these scenarios, the ApplicationUser class (which is derived from IdentityUser ) cannot be serialized. Attempting to do so will yield an

Breeze filtering .Expand on server side

由 泄露秘密 提交于 2019-12-04 04:33:03
问题 I'm trying out BreezeJS . There is a requirement that I can use .expand in the client side code, but based on the role of the user, the server side will not return all the records for the .expand requested type. I tried to create a custom BreezeQueryable attribute and override a method to completely filter out the extra data first just to try. But it threw an exception. I don't see any entry point where I can do that on the server side. Please guide me in the right direction, or let me know

Generic Web Api method

由 喜欢而已 提交于 2019-12-04 04:30:36
I've some classes like CustomerModel or CustomerDetailsModel which are inherting from ModelBase . Also i don't want to introduce subclasses for each modeltype. In one case have a post method foreach. So i could manually create multiple routes to call a method which looks like Handle<T>(T model) where T : ModelBase They only differ in the path the were called. For example: baseurl/api/customer => CustomerModel baseurl/api/customerdetails => CustomerDetailsModel I want to implement a generic web api method like [HttpPost] void Post<T>(T model) where T : ModelBase If I simply create a generic
