问题
I'm trying to create a WebApi action method with the following signature:
[System.Web.Http.HttpPost]
public object Execute([FromUri] string command, [FromUri] string method, [FromBody] IDictionary<string, JToken> arguments)
However, when I hit this method with requests, arguments never binds correctly (the two URI fields do). The ModelState shows a Json.NET parse error at the first character. I've tried request bodies that look like: id=50 and arguments={ "id": 50 }. How do I have to formulate my request to allow WebApi to correctly bind my parameters?
回答1:
You don't need the "id=" or "arguments=" in the request body. You should be able to just send something that looks like this:
{"key1": 4, "key2": 50, "key3": {"member1": "value"}}
and have it work. The Dictionary would then contain key1: a JValue with value 4, key2: a JValue with value 50, key3: a JObject with a member1 member with value "value".
