7. 基础增删改 - 使用Portal Webapi进行会员信息的增删改

我们可以通过使用Portal Web API在Portal页面中跨所有Microsoft Dataverse表执行创建、更新和删除操作，下面我们就一起来看一下如何通过使用AJAX函数来进行操作。

AJAX函数：

(function(webapi, $){
        function safeAjax(ajaxOptions) {
            var deferredAjax = $.Deferred();
    
            shell.getTokenDeferred().done(function (token) {
                // add headers for AJAX
                if (!ajaxOptions.headers) {
                    $.extend(ajaxOptions, {
                        headers: {
                            "__RequestVerificationToken": token
                        }
                    }); 
                } else {
                    ajaxOptions.headers["__RequestVerificationToken"] = token;
                }
                $.ajax(ajaxOptions)
                    .done(function(data, textStatus, jqXHR) {
                        validateLoginSession(data, textStatus, jqXHR, deferredAjax.resolve);
                    }).fail(deferredAjax.reject); //AJAX
            }).fail(function () {
                deferredAjax.rejectWith(this, arguments); // on token failure pass the token AJAX and args
            });
    
            return deferredAjax.promise();  
        }
        webapi.safeAjax = safeAjax;
    })(window.webapi = window.webapi || {}, jQuery)

在表中创建记录：

webapi.safeAjax({
        type: "POST",
        url: "/_api/accounts",
        contentType: "application/json",
        data: JSON.stringify({
            "name": "Sample Account"
        }),
        success: function (res, status, xhr) {
      //print id of newly created table record
            console.log("entityID: "+ xhr.getResponseHeader("entityid"))
        }
    });

在表中更新记录：

webapi.safeAjax({
    type: "PATCH",
    url: "/_api/accounts(00000000-0000-0000-0000-000000000001)",
    contentType: "application/json",
    data: JSON.stringify({
      "name": "Sample Account - Updated"
    }),
    success: function (res) {
      console.log(res);
    }
  });

在表中删除记录：

webapi.safeAjax({
        type: "DELETE",
        url: "/_api/accounts(00000000-0000-0000-0000-000000000001)",
        contentType: "application/json",
        success: function (res) {
            console.log(res);
        }
  });
