In my MVC that consumes a REST API, I want to send a List of User objects to the REST API. Can the @RequestParam annotation support that?

问题 I have some jQuery that sends data to a AddComment.php page. The data is a user id (could be gotten through a session), an item id and a comment under text form. In this case, should all data be sent through a POST? Are there cases where one might find a mix of GET and POST? 回答1: Go read RFC 2616.

问题 The following code sends a GET request. This is making me crazy. let postDocRaw (url:string) (data: string) : string = let data' : byte[] = System.Text.Encoding.ASCII.GetBytes(data); let request = WebRequest.Create(url) request.Method <- "POST" request.ContentType <- "application/x-www-form-urlencoded" request.ContentLength <- (int64) data'.Length use wstream = request.GetRequestStream() wstream.Write(data',0, (data'.Length)) wstream.Flush() wstream.Close() (* use writer = new StreamWriter

问题 In Razor I know that if you write @Html.HiddenFor(x => x.PropertyX.PropertyY) it will generate HTML like: <input type="hidden" name="PropertyX.PropertyY" value="..."> And (especially) if this was in an Editor Template it might generate this HTML: <input type="hidden" name="ParentProperty[12].PropertyX.PropertyY" value="..."> How do I get a name for an arbitrary property?

问题 I've previously used Square's Retrofit successfully for a @GET web API call but when trying to send JSON as the @BODY in a @POST call, on the server (Rails) the JSON is showing up as Parameters rather than the body request. My understanding is that @BODY will add that method parameter to the request in the body. Any idea what I'm doing wrong? WebApi : @POST("/api/v1/gear/scans.json") Response postScans( @Header(HEADER_AUTH) String token, @Body JsonObject scans ); Make web request: RestAdapter
