eine ungültige Anfrage URI bereitgestellt wurde in Datatable WebAPI Aufruf

Question

An invalid request URI was provided. The request URI must either be an absolute URI or BaseAddress must be set. 

Hier ist der Api Controller:

EmailTemplate.UI\Areas\Ticket\Api\TicketController.cs 

hier ist der Code:

var client = new HttpClient(); 


       string _url = _apiTicket + "Areas/Ticket/Api/TicketController/Get/10?PageIndex=" + pageIndex + "&PageSize=" + pageSize; 
       var response = client.GetAsync(_url).Result; 
       var result1 = response.Content.ReadAsStringAsync().Result; 

hier als Reaktion dieser Fehler kommt.

i von pageindex und Seitengröße in Datatable Server-Seite mvc 4.

Hier Daten filtern wollen, ist das Verfahren in api:

public HttpResponseMessage Get1(int UserId) 
    { 
     string _searchString = GetQueryValueByName.Get(Request.GetQueryNameValuePairs(), "searchstr"); 
     int _start = int.Parse(GetQueryValueByName.Get(Request.GetQueryNameValuePairs(),"start")); 
     int _length =int.Parse(GetQueryValueByName.Get(Request.GetQueryNameValuePairs(),"length")); 
     List<sp_Ticketlist_Result> _dbData; 
     int _dataTotaRowCount; 
     _dbData = _repository.GetTicket(UserId).ToList(); 
     _dataTotaRowCount = _dbData.Count(); 
     if (!string.IsNullOrEmpty(_searchString)) 
     { 
      _dbData = _dbData.Where(m => 
      m.Name.ToUpper().Contains(_searchString.ToUpper())).ToList(); 
      _dataTotaRowCount = _dbData.Count(); 
      _dbData = _dbData.Skip(_start).Take(_length).ToList(); 
     } 
     else 
     { 
      _dbData = _dbData.Skip(_start).Take(_length).ToList(); 
     } 
     return Request.CreateResponse(HttpStatusCode.OK,DataTableObjectConverter.ConvertData(_dbData, _dataTotaRowCount)); 
    } 
    public static class GetQueryValueByName 
    { 
     public static string Get(IEnumerable<KeyValuePair<string, string>> _req, 
           string key) 
     { 
      return _req.FirstOrDefault(ma => string.Compare(ma.Key, key) == 
             0).Value; 
     } 
    } 
    public static class DataTableObjectConverter 
    { 
     public static DataTableObject ConvertData<T>(T source, int count) 
      where T : class, new() 
     { 
      DataTableObject _obj = new DataTableObject(); 
      //_obj.draw = 1; 
      _obj.recordsFiltered = count; 
      _obj.recordsTotal = count; 
      _obj.data = source; 
      return _obj; 
     } 
    } 

Gibt es für jedes Verfahren, mit pageindex und Seitengrße müssen ??

Wie kann ich Daten über pageIndex aufrufen und pagesize definiert in Methode ??

Hier ist meine Methode GetData:

public ActionResult GetData() 
     { 
      // Initialization. 
      JsonResult result = new JsonResult(); 

      try 
      { 
       // Initialization. 
       string search = Request.Form.GetValues("search[value]")[0]; 
       string draw = Request.Form.GetValues("draw")[0]; 
       string order = Request.Form.GetValues("order[0][column]")[0]; 
       string orderDir = Request.Form.GetValues("order[0][dir]")[0]; 
       int startRec = Convert.ToInt32(Request.Form.GetValues("start")[0]); 
       // int pageSize = Convert.ToInt32(Request.Form.GetValues("length")[0]); 


       var start = Request.Form.GetValues("start").FirstOrDefault(); 
       var length = Request.Form.GetValues("length").FirstOrDefault(); 
       int pageSize = length != null ? Convert.ToInt32(length) : 0; 
       int recordStatr = start != null ? Convert.ToInt32(start) : 0; 
       recordStatr = recordStatr == 0 ? 1 : recordStatr; 
       var pageIndex = (recordStatr/pageSize) + 1; 
       int recordsTotal = 0; 
       // Loading. 
       List<AppTicket> data = this.LoadData(); 

       // Total record count. 
       int totalRecords = data.Count; 

       // Verification. 
       //if (!string.IsNullOrEmpty(search) && 
       // !string.IsNullOrWhiteSpace(search)) 
       //{ 
       // // Apply search 
       // data = data.Where(p => p.Title.ToString().ToLower().Contains(search.ToLower()) || 
       //       p.Name.ToLower().Contains(search.ToLower()) || 
       //       p.Email.ToString().ToLower().Contains(search.ToLower())).ToList(); 
       // //p.ProductName.ToLower().Contains(search.ToLower()) || 
       // //p.SpecialOffer.ToLower().Contains(search.ToLower()) || 
       // //p.UnitPrice.ToString().ToLower().Contains(search.ToLower()) || 
       // //p.UnitPriceDiscount.ToString().ToLower().Contains(search.ToLower())).ToList(); 
       //} 

       // Sorting. 
       data = this.SortByColumnWithOrder(order, orderDir, data); 

       // Filter record count. 
       int recFilter = data.Count; 

       // Apply pagination. 
       // data = data.Skip(startRec).Take(pageSize).ToList(); 

       // Loading drop down lists. 
       // result = this.Json(new { draw = Convert.ToInt32(draw), recordsTotal = totalRecords, recordsFiltered = recFilter, data = data }, JsonRequestBehavior.AllowGet); 





       //Find Order Column 
       //var sortColumn = Request.Form.GetValues("columns[" + Request.Form.GetValues("order[0][column]").FirstOrDefault() + "][name]").FirstOrDefault(); 
       //var sortColumnDir = Request.Form.GetValues("order[0][dir]").FirstOrDefault(); 




       var client = new HttpClient(); 


       //client.BaseAddress = new Uri("http://localhost:1849"); 
       //client.DefaultRequestHeaders.Accept.Clear(); 
       // client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 
       // string _url = _apiTicket + ".Get?UserId=" + 10 + "&PageIndex=" + pageIndex + "&PageSize=" + pageSize; 
       //var response = client.GetAsync(_url).Result; 
       //var response1 = client.GetAsync("/Areas/Ticket/Api/Get/10,10,10").Result; 
       //if (response1.IsSuccessStatusCode) 
       //{ 
       // string responseString = response.Content.ReadAsStringAsync().Result; 
       //} 
       // string _url = _apiTicket + "Get1/10?searchstr=Monaj&PageIndex=" + pageIndex + "&PageSize=" + pageSize; 
       // string apiUrl = "Api/Ticket/10?searchstr=Monaj&PageIndex=" + pageIndex + "&PageSize=" + pageSize; 
       string apiUrl = "../Areas/api/Ticket/1?searchstr=Monaj&start=0&length=10"; 
       var response = client.GetAsync(apiUrl).Result; 
       var result1 = response.Content.ReadAsStringAsync().Result; 



       // HttpResponseMessage response = await client.GetAsync(_url); 
       // HttpResponseMessage response = client.GetAsync(_url).Result; 
       //var response = client.GetAsync(_url).Result; 
       // var result1 = response.Content.ReadAsStringAsync().Result; 

       JsonResult jsonresult = Json(result1, JsonRequestBehavior.AllowGet); 
       AppTicket _contacts = new AppTicket(); 

       _contacts = JsonConvert.DeserializeObject<AppTicket>(jsonresult.Data.ToString()); 

       //return Json(new { draw = draw, recordsFiltered = recordsTotal, recordsTotal = recordsTotal, data = _contacts.listcourses }, JsonRequestBehavior.AllowGet); 
       result = this.Json(new { draw = Convert.ToInt32(draw), recordsFiltered = totalRecords, recordsTotal = recordsTotal, data = data }, JsonRequestBehavior.AllowGet); 




      } 
      catch (Exception ex) 
      { 
       // Info 
       Console.Write(ex); 
      } 

      // Return info. 
      return result; 
     } 

ich die json Ajax hier in custom-datatable.js verwenden. hier ist der Code:

$(document).ready(function() 
{ 
    debugger 
    $('#TableId').DataTable(
    { 
     //"columnDefs": [ 
     // { "width": "5%", "targets": [0] }, 
     // { 
     //  "className": "text-center custom-middle-align",

     // }, 
     //], 
     'columnDefs': [{

      'searchable': false,

      'render': function (data, type, full, meta) { 
       return '<input type="checkbox">'; 
      } 
     } 
     , 
      { 
       targets: 2, 
       render: function (data, type, row, meta) { 
        if (type === 'display') { 
         data = '<a href="/TicketTemplate/AppDetails/' + row.Id + ' " >' + data + '</a>'; 
        } 

        return data; 
       } 
      }, 

      { 
       targets: 1, 
       render: function (data, type, row, meta) { 
        return moment(data).format('DD/MM/YYYY HH:mm:ss');     
       } 
      } 
     ], 
     "language": 
      { 
       "processing": "<div class='overlay custom-loader-background'><i class='fa fa-cog fa-spin custom-loader-color'></i></div>"

        //  //return '<a href=\"' + title + '\">' + title + '</a>'; 
        //  return '<a href="' + title + '">' + data + '</a>'; 
        // } 
        //}, 
         //{ 
         //{

         //  return "<a href=" + "/" + "/TicketTemplate/AppDetails/" + row.Id + " id=" + row.Id + ">" + row.Title + " </a>"; 


         // } 
         //}, 

        { "data": "Name" },

        { "data": "AssignTo" }, 
        { "data": "Status" }     
     ] 




    }); 
}); 

Zunächst einmal ist es das MVC-Controller GetData getroffen() und in GetData() rufen die Api-Controller Get(). Paging Sortierung Suche alle sind in der Verwendung von API dynamisch.

Answer 1

Wie Sie in Ihrem Kommentar erwähnt, dass „i die Datentabelle Paging Sortierung der Suche durch MVC-Controller und Web-api Controller nennen wollen“, dann würde ich empfehlen, so zu tun, das ist, was ich in getan haben viele Projekte.

//This is my API Get method 
public HttpResponseMessage Get(int id) 
{ 
    string _searchString = 
    GetQueryValueByName.Get(Request.GetQueryNameValuePairs(), "searchstr"); 
    int _start = 
    int.Parse(GetQueryValueByName.Get(Request.GetQueryNameValuePairs(), 
      "start")); 
    int _length = 
    int.Parse(GetQueryValueByName.Get(Request.GetQueryNameValuePairs(), 
      "length")); 
    List<sp_Ticketlist_Result> _dbData; 
    int _dataTotaRowCount; 
    _dbData = _repository.GetTicket(id).ToList(); 
    _dataTotaRowCount = _dbData.Count(); 
    if (!string.IsNullOrEmpty(_searchString)) 
     { 
     _dbData = _dbData.Where(m => 
     m.Name.ToUpper().Contains(_searchString.ToUpper())).ToList(); 
     _dataTotaRowCount = _dbData.Count(); 
     _dbData = _dbData.Skip(_start).Take(_length).ToList(); 
     } 
    else 
     { 
     _dbData = _dbData.Skip(_start).Take(_length).ToList(); 
     } 
    return Request.CreateResponse(HttpStatusCode.OK, 
    DataTableObjectConverter.ConvertData(_dbData, _dataTotaRowCount)); 
    } 

Bellow ist mein GetQueryValueByName und DataTableObjectConverter Klasse, dass ich in einer separaten Klassendatei gehalten und nur auf meine Api-Controller verweisen.

public static class GetQueryValueByName 
{ 
public static string Get(IEnumerable<KeyValuePair<string, string>> _req, 
          string key) 
    { 
    return _req.FirstOrDefault(ma => string.Compare(ma.Key, key) == 
           0).Value; 
    } 
} 

public static class DataTableObjectConverter 
{ 
    public static DataTableObject ConvertData<T>(T source, int count) 
     where T : class, new() 
    { 
     DataTableObject _obj = new DataTableObject(); 
     //_obj.draw = 1; 
     _obj.recordsFiltered = count; 
     _obj.recordsTotal = count; 
     _obj.data = source; 
     return _obj; 
    } 
} 

public class DataTableObject 
{ 
    public int recordsTotal { get; set; } 
    public int recordsFiltered { get; set; } 
    public Object data { get; set; } 
} 

Dann wird meine URL so sein,

string apiUrl = "http://localhost:55442/api/Ticket/1? 
       searchstr=Monaj&start=0&length=10"; 
var client = new HttpClient(); 
var response = client.GetAsync(apiUrl).Result; 
var result1 = response.Content.ReadAsStringAsync().Result; 

Hinweis: See, hier bin ich vorbei Start, Länge, Such-String als Abfrage-String und ich holen sie in meinem API-Get-Methode. Aktualisieren Sie einfach Ihre URL hier und geben Sie keine / in Abfrage-String-Parameter. Sie haben so geschrieben,

" + pageIndex + "/PageSize=" + pageSize; 

Das ist falsch. Überprüfen Sie, wie ich es gemacht habe. Sie müssen trennen durch &
