能使用幫助確定500（內部服務器錯誤）的源這裏

Question

我對處理請求的方法是

[HttpPost] 
    public ActionResult SubmitNew (SolutionSubmission SS) 
    { 
     // Going to move this to model later .. 
     using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["LocalJsPracticeDb"].ConnectionString)) 
     { 
      SqlCommand cmd = new SqlCommand("AddSolution", con); 
      cmd.CommandType = CommandType.StoredProcedure; 

      cmd.Parameters.AddWithValue("@problem_id", SS.ProblemId); 
      cmd.Parameters.AddWithValue("@solver", SS.Solver); 
      cmd.Parameters.AddWithValue("@solution_code", SS.SolutionCode); 
      cmd.Parameters.AddWithValue("@test_code", SS.TestCode); 
      /* 
      cmd.Parameters.AddWithValue("@problem_id", 1); 
      cmd.Parameters.AddWithValue("@solver", "Jeff"); 
      cmd.Parameters.AddWithValue("@solution_code", "<span>Hehe</span>"); 
      cmd.Parameters.AddWithValue("@test_code", "<p>Yo</p>"); */ 
      con.Open(); 
      cmd.ExecuteNonQuery(); 
     } 
     return Json(new { success = true }) ; // TEST 
    } 

    // Going to move this to model later ... 
    public class SolutionSubmission 
    { 
     public int ProblemId { get; set; } 
     public string Solver { get; set; } 
     public string SolutionCode { get; set; } 
     public string TestCode { get; set; } 
    } 

，我打電話與

 $('#submit-solution').click(function() { 
      var rowData = { 
       ProblemId : $('input[name="problem_id"]').val(), 
       Solver : $('input[name="solver"]').val(), 
       SolutionCode: $('#solution').html(), 
       TestCode : $('#testfuncs').html() 
      }; 
      console.log(rowData); // TEST 
      $.ajax({ 
       url: 'SubmitNew', 
       method: 'POST', 
       data: rowData, 
       success: function (retobj) { 
        // ... 
       }, 
       error: function () { 
        // ... 
       } 

      }) 
     }); 

要求我驗證過rowData是在我的測試案例中有效：它是（字符串）

{"ProblemId":"1","Solver":"adas","SolutionCode":"\n\n  <div class=\"CodeMirror cm-s-default\"><div style=\"overflow: hidden; position: relative; width: 3px; height: 0px; top: 4px; left: 4px;\"><textarea autocorrect=\"off\" autocapitalize=\"off\" spellcheck=\"false\" style=\"position: absolute; padding: 0px; width: 1000px; height: 1em; outline: none;\" tabindex=\"0\"></textarea></div><div class=\"CodeMirror-vscrollbar\" cm-not-content=\"true\"><div style=\"min-width: 1px; height: 0px;\"></div></div><div class=\"CodeMirror-hscrollbar\" cm-not-content=\"true\"><div style=\"height: 100%; min-height: 1px; width: 0px;\"></div></div><div class=\"CodeMirror-scrollbar-filler\" cm-not-content=\"true\"></div><div class=\"CodeMirror-gutter-filler\" cm-not-content=\"true\"></div><div class=\"CodeMirror-scroll\" tabindex=\"-1\"><div class=\"CodeMirror-sizer\" style=\"margin-left: 0px; margin-bottom: -23px; border-right-width: 7px; min-height: 48px; min-width: 253.208px; padding-right: 0px; padding-bottom: 0px;\"><div style=\"position: relative; top: 0px;\"><div class=\"CodeMirror-lines\"><div style=\"position: relative; outline: none;\"><div class=\"CodeMirror-measure\"><span><span>​</span>x</span></div><div class=\"CodeMirror-measure\"></div><div style=\"position: relative; z-index: 1;\"></div><div class=\"CodeMirror-cursors\"><div class=\"CodeMirror-cursor\" style=\"left: 4px; top: 0px; height: 20px;\">&nbsp;</div></div><div class=\"CodeMirror-code\"><pre class=\" CodeMirror-line \"><span style=\"padding-right: 0.1px;\"><span class=\"cm-keyword\">function</span> <span class=\"cm-def\">myScript</span>(){<span class=\"cm-keyword\">return</span> <span class=\"cm-number\">100</span>;}</span></pre><pre class=\" CodeMirror-line \"><span style=\"padding-right: 0.1px;\"><span cm-text=\"\">​</span></span></pre></div></div></div></div></div><div style=\"position: absolute; height: 7px; width: 1px; top: 48px;\"></div><div class=\"CodeMirror-gutters\" style=\"display: none; height: 308px;\"></div></div></div>","TestCode":"\n\n  <div class=\"CodeMirror cm-s-default\"><div style=\"overflow: hidden; position: relative; width: 3px; height: 0px; top: 4px; left: 4px;\"><textarea autocorrect=\"off\" autocapitalize=\"off\" spellcheck=\"false\" style=\"position: absolute; padding: 0px; width: 1000px; height: 1em; outline: none;\" tabindex=\"0\"></textarea></div><div class=\"CodeMirror-vscrollbar\" cm-not-content=\"true\"><div style=\"min-width: 1px; height: 0px;\"></div></div><div class=\"CodeMirror-hscrollbar\" cm-not-content=\"true\"><div style=\"height: 100%; min-height: 1px; width: 0px;\"></div></div><div class=\"CodeMirror-scrollbar-filler\" cm-not-content=\"true\"></div><div class=\"CodeMirror-gutter-filler\" cm-not-content=\"true\"></div><div class=\"CodeMirror-scroll\" tabindex=\"-1\"><div class=\"CodeMirror-sizer\" style=\"margin-left: 0px; margin-bottom: -23px; border-right-width: 7px; min-height: 48px; min-width: 253.208px; padding-right: 0px; padding-bottom: 0px;\"><div style=\"position: relative; top: 0px;\"><div class=\"CodeMirror-lines\"><div style=\"position: relative; outline: none;\"><div class=\"CodeMirror-measure\"></div><div class=\"CodeMirror-measure\"></div><div style=\"position: relative; z-index: 1;\"></div><div class=\"CodeMirror-cursors\"><div class=\"CodeMirror-cursor\" style=\"left: 4px; top: 0px; height: 20px;\">&nbsp;</div></div><div class=\"CodeMirror-code\"><pre class=\" CodeMirror-line \"><span style=\"padding-right: 0.1px;\"><span class=\"cm-keyword\">function</span> <span class=\"cm-def\">myScript</span>(){<span class=\"cm-keyword\">return</span> <span class=\"cm-number\">100</span>;}</span></pre><pre class=\" CodeMirror-line \"><span style=\"padding-right: 0.1px;\"><span cm-text=\"\">​</span></span></pre></div></div></div></div></div><div style=\"position: absolute; height: 7px; width: 1px; top: 48px;\"></div><div class=\"CodeMirror-gutters\" style=\"display: none; height: 308px;\"></div></div></div>"} 

不過，由於某種原因，我得到了50 0（內部服務器錯誤）。我得到了同樣的錯誤，當我在

  /* 
      cmd.Parameters.AddWithValue("@problem_id", SS.ProblemId); 
      cmd.Parameters.AddWithValue("@solver", SS.Solver); 
      cmd.Parameters.AddWithValue("@solution_code", SS.SolutionCode); 
      cmd.Parameters.AddWithValue("@test_code", SS.TestCode); 
      */ 
      cmd.Parameters.AddWithValue("@problem_id", 1); 
      cmd.Parameters.AddWithValue("@solver", "Jeff"); 
      cmd.Parameters.AddWithValue("@solution_code", "<span>Hehe</span>"); 
      cmd.Parameters.AddWithValue("@test_code", "<p>Yo</p>"); 

因此也有一些問題，我不具有與方法的身體做SubmitNew方法替代。任何想法可能是錯的？

Answer 1

好吧，夥計們。我通過添加

   dataType: 'json', 
       processData: false, 

到我傳遞給服務器的JSON。
