Visual Web部件ajax http 500内部服务器错误问题 [英] Visual web part ajax http 500 internal server error issue

问题描述

Hello,
        I have created visual web part for fetching data from SharePoint list and display on it.
For fetching data from list I have used server object model. For fetching data from SharePoint list I have created "Application Page" and written code in it.  
     In application page I have mentioned the method as a "[WebMethod]".I am calling application page method by using Ajax (i.e. from Sample.ascx page).
On search button I have written code for calling Application Page method "GetFilterResults" by using Ajax.
Problem is that when I click on search button it is giving error 500 Internal Server error that is Ajax is not calling "GetFilterResults" method it jumps to the "error method of Ajax".
   One thing to mention is that, the code is working fine on Development, System Test and UAT environment only it is not working on "Production" environment.
  Below is the sample code in Visual Web Part page (i.e. in Sample.ascx page).

我尝试过：

What I have tried:

//Call Ajax function for getting filter condition results from Content Metadata Master List               

var parameters = { arrFilters: FilterArray, arrFilterCondition: FilterConditionArray };
$.ajax({
type: "POST",
async: false,
url: "/_layouts/15/BulkWorkflow/BulkWorkflowCode.aspx/GetFilterResults",
data: JSON.stringify(parameters),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
	
var data1 = jQuery.parseJSON(response.d)

for (var i in data1) {

 alert(data1[i].ContentID + ", " + data1[i].ContentName + " , " + data1[i].ContentTitle);	

}
},
error: function (xhr, ajaxOptions, thrownError) {
alert("Error");
alert(xhr.status);
alert(thrownError);
}
});

And code in Application page (i.e. in BulkWorkflowCode.aspx page),

[WebMethod]
public static string GetFilterResults(string[] arrFilters, string[] arrFilterCondition)
{
	
	//Code for fetching data from SharePoint list and return output as a String
}

also I have checked the error logs in  Fiddler tool 

它给出了以下错误，



{消息：处理请求时出错。，StackTrace：，Exc eptionType：}

it is giving following error,

{"Message":"There was an error processing the request.","StackTrace":"","ExceptionType":""}

推荐答案

.ajax（{
type： POST，
async ： false ，
url： / _ layouts / 15 / BulkWorkflow / BulkWorkflowCode.aspx / GetFilterResults，
data：JSON.stringify（parameters），
contentType： application / json; charset = utf-8，
dataType： json，
成功：函数（响应）{

var data1 = jQuery.parseJSON（response.d）

for （ var i in data1） {

alert（data1 [i] .ContentID + ， + data1 [i] .ContentName + ， + data1 [i] .ContentTitle）;

}
}，
错误：function（xhr，ajaxOptions，thrownError）{
alert（ 错误）;
alert（xhr.status）;
alert（thrownError）;
}
}）;

.ajax({ type: "POST", async: false, url: "/_layouts/15/BulkWorkflow/BulkWorkflowCode.aspx/GetFilterResults", data: JSON.stringify(parameters), contentType: "application/json; charset=utf-8", dataType: "json", success: function (response) { var data1 = jQuery.parseJSON(response.d) for (var i in data1) { alert(data1[i].ContentID + ", " + data1[i].ContentName + " , " + data1[i].ContentTitle); } }, error: function (xhr, ajaxOptions, thrownError) { alert("Error"); alert(xhr.status); alert(thrownError); } });

And code in Application page (i.e. in BulkWorkflowCode.aspx page),

[WebMethod]
public static string GetFilterResults(string[] arrFilters, string[] arrFilterCondition)
{
	
	//Code for fetching data from SharePoint list and return output as a String
}

also I have checked the error logs in  Fiddler tool 

它发出以下错误，
