javascript - MVC controller's string[] parameter is null when posting JSON data -

-

I post data with jQuery but I have problems with array data. The values ​​given for the MVC controller are always zero.

This is my JavaScript code: 

  var FilterCategory = $ ('input: checkbox: check'). Map (function () {return.value;}). (); Var posting = $ Post (url, {cursorid: lastid, CatFilter: FilterCategory});   
 Form data from network:  
  cursorid: 5434cdc84ba4dd0c40396851 filter [1]: 1 filter []: 3 filter []: 4   Here is the C # side:  
  Public action results GetDataTweets (string cursor, string [] catfilter) {bla bla}   
 Cursorid   
 
 < P> This code is here:  
  var posting = $ .post (url, {cursorid: lastid, catfilter: filtercategory});   
 This is sending a class from MVC perspective, so to package the data you need reciprocal C # class. Create a class to handle that data, for example:  
 I assume that your catfilter array is a string array:  
  public class data {public string cursorid {Get; Set;} public string [] CatFilter {get; Set up;}}   
 Then change your controller:  
  Public functions GetDataTweets (data data) {var s1 = data.cursorid; Var s2 = data.CatFilter [0]; }   
 If CatFilter is a class, then you have to create a catfilter category to map to a javascript version.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
