问题 I disabled lazy loading and proxy creation in EF5 before returning any results in the Web Api. Everything worked fine. However, when i start to Include() other entities for eager fetching, some of the JSON objects look like this: { $ref: "14" }, .. correct objects .. { $ref: "6" }, .. What is this "$ref" that gets included in the list of results? 回答1: It's coming from the JSON.NET serializer. It's preserving object references. Take a look at the following blog post. I guess you have some

问题 I know you can apply a wildcard in the route attribute to allow / such as date input for example: [Route("orders/{*orderdate}")] The problem with wildcard is only applicable to the last paramter in URI. How do I solve the issue if want to have the following URI: [Route("orders/{orderdate}/customers")] Update: I know there are few options to solve the issue by refactoring the code so please do not offer a solution something like: change the route template to [Route("orders/customers/{orderdate

问题 My beautiful REST webservice works great. Except if I visit pages like ~/ , which returns the default IIS 403 Forbidden page (even using Fiddler and specifying only Accept: application/json ). I want nothing but JSON or XML errors. Is there a way to override ALL exceptions with a custom exception handler? or a default controller to handle all unknown requests? What's the simplest, and the most correct (if different), way to handle this so that clients need only parse REST API-friendly XML

问题 I faced a problem. When you add multiple Set-Cookie headers to the response headers.Add("Set-Cookie", "a=b;Path=/;"); headers.Add("Set-Cookie", "c=d;Path=/;"); actually they are combined and only one header is sent with comma-separated cookies Set-Cookie: a=b;Path=/;,c=d;Path=/; According to RFC2109 it is a valid syntax. But it is not according to RFC6265, which deprecates RFC2109 Moreover latest browsers does not support this comma-separated syntax as well. Tested on IE9 , Firefox 13 and

问题 I would like to control which properties from my model are serialized to my WebAPI2 JSON response, based on matching a query parameter to an attribute. I mainly want to do this to reduce bandwidth on GETs without causing a proliferation of ViewModel classes. For example: GET /books/1?format=summary public class Book { [SerializeFormat("summary")] public int Id { get; set; } [SerializeFormat("summary")] public string Title { get; set; } public string Contents { get; set; } } or

问题 Overriding the default JSON serializer settings for web API on application level has been covered in a lot of SO threads. But how can I configure its settings on action level? For example, I might want to serialize using camelcase properties in one of my actions, but not in the others. 回答1: Option 1 (quickest) At action level you may always use a custom JsonSerializerSettings instance while using Json method: public class MyController : ApiController { public IHttpActionResult Get() { var
