问题 I want to host my API on a separate domain. I have configured my auth-interceptor for token in angular with a bearer: config.headers.Authorization = 'Bearer ' + sessionStorage.getItem('token'); In my My WebApi2 I have configured the WebApiConfig with cors. var cors = new EnableCorsAttribute("http://mydomain.com", "*", "*"); config.EnableCors(cors); And in web.config of the API I also included: <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> </customHeaders> I still can´t

问题 I was looking for Caching in my web api where i can use output of one api method(that changes once in 12hrs) for subsequesnt calls and then i found this solution on SO,but i am having a difficulty in understanding and using the below code private IEnumerable<TEntity> GetFromCache<TEntity>(string key, Func<IEnumerable<TEntity>> valueFactory) where TEntity : class { ObjectCache cache = MemoryCache.Default; var newValue = new Lazy<IEnumerable<TEntity>>(valueFactory); CacheItemPolicy policy = new

问题 I have a Web API project that returns some product data. It negotiates the return type correctly depending on the Accept header (JSON/XML) of the request. The problem is, if no Accept header is specified it returns XML, but I want it to return JSON by default http://website.com/MyPage?type=json // returns json http://website.com/MyPage?type=xml // returns xml http://website.com/MyPage // returns xml by default Here is my current code looks like: GlobalConfiguration.Configuration.Formatters

问题 I have a WEB API 2 call, with Entity Framework. If I update a DateTime column from my entity that I read from the database with DateTime.Now , and I serialize it to the client, the column with DateTime that I received from the database has 3 numbers for the milliseconds, but the column with DateTime that I updated in the C# code has 6 digits. Below is the C# code in my controller: [Route("{id:long}/updatedatetime", Name = "UpdateDateTimeByID")] [HttpPost] [ResponseType(typeof(ClGroup))]

问题 In short, I have two database tables: Languages and Frameworks. The important thing is that there is one-to-many relation between the tables(one language has many frameworks). I am designing a RESTful(WebAPI2) service to consume the information from these tables. I am using the repository pattern.

问题 I have a challenge with Swashbuckle or Swagger. I'm not sure if the problem is with Swagger or Swashbuckle. I have web api call, implemented both with the parameter as URI params, and with reading the content from the body of the request.

问题 I have a problem with using multiple filters on my WebAPI 2 Odata project. We only want JSON output and only have one object type to query so we set the url to "/" without the possibility to use a different controller. I have an object I want to query with the following properties: public class Content { public int Id { get; set; } public string Title { get; set; } public string Excerpt { get; set; } public string Link { get; set; } public IList<Tag> Tags { get; set; } } public class Tag {
