通过SP.RequestExecutor以Nintex形式更新SharePoint列表项的问题

如何解决通过SP.RequestExecutor以Nintex形式更新SharePoint列表项的问题

我尝试更新SharePoint列表项中的日期/时间字段，但是当我尝试执行此操作时出现403错误。通过多种方式进行了尝试，可以认为该CORS代理库在许多地方不适用于“ POST”方法。关于如何解决这个问题有什么想法吗？

下面是我使用的代码。

var hostweburl;
var appweburl;
var context;
var factory;
var appContextSite;
var currentDateTime;
var itemId;

function SetTheDate() {
    hostweburl = decodeURIComponent(getquerystringparameter("SPHostUrl"));
    appweburl = decodeURIComponent(
        getquerystringparameter("SPAppWebUrl")
    );

    var cDate = "fn-FormatDate(Current Date,MM/dd/yyyy)";
    var cTime = "fn-FormatDate(Current Time,t)";
    currentDateTime = cDate + ' ' + cTime;
    itemId = getParameterByName('ID');

    if (itemId !== 'undefined' || itemId !== null) {
        /*
  var scriptbase = hostweburl + "/_layouts/15/";
    $.getScript(scriptbase + "SP.Runtime.js",function () {
                $.getScript(scriptbase + "SP.js",executeSP);
            }
        );
*/
        executeSP();
    }
}

function executeSP() {
    
    var executor = new SP.RequestExecutor(appweburl);
    var itemType = GetItemTypeForListName("AMB");
    var item = {
        "__Metadata": {
            "type": itemType
        },"UIModifiedDate": currentDateTime
    };

    var jsonBody = JSON.stringify(item);

    var restUrl = appweburl + "/_api/SP.AppContextSite(@target)/web/lists/getbytitle('AMB')/items(" + itemId + ")?@target='" +
        hostweburl + "'";
  
    executor.executeAsync({
        url: restUrl,method: "POST",body: jsonBody,headers: {
            "accept": "application/json;odata=verbose","content-type": "application/json;odata=verbose","X-HTTP-Method": "MERGE","content-length": jsonBody.length,"If-Match": "*"
        },success: successHandler,error: errorHandler
    });

}

请告知。
