 1、创建Site Settings

 

添加要使用表的site settings 两条

格式为：

Webapi/[表名]/enabled ： 启用此表

Webapi/[表名]/fields： 要查找的字段

如：

Webapi/contact/enabled

Webapi/contact/fields

填写到name，website选择要用到这个的portal网站；

enabled中value填True

fields中value填要查的字段名，逗号隔开，或者查全部字段名填写“*”；

 

 2、在自定义js中使用它

(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;
            }

        }).fail(function () {
            deferredAjax.rejectWith(this, arguments); // On token failure pass the token ajax and args
        });
        $.ajax(ajaxOptions)
            .done(function (data, textStatus, jqXHR) {
                //validateLoginSession(data, textStatus, jqXHR, deferredAjax.resolve);
            }).fail(deferredAjax.reject); //ajax
        return deferredAjax.promise();
    }
    webapi.safeAjax = safeAjax;
})(window.webapi = window.webapi || {}, jQuery)

function Test(){
    webapi.safeAjax({
        type: "get",
        url: "/_api/contacts",
        contentType: "application/json",
        async: false,
        success: function (res, status, xhr) {
            console.log(res)
        }, error: function (res) {
            console.log("error", res);
        }

    });
}

　在使用前可以先用portal网址+“/_api/contacts”，测试下是否正常

3、更新与新增

//更新
webapi.safeAjax({
        type: "PATCH",
        url: "/_api/[表名](" + [主键id]+ ")",
        contentType: "application/json",
        async: false,
        data: JSON.stringify(recordObj),
        success: function (res) {
            console.log(res);
        }, error: function (ex) {
            console.log(ex);
            //alert("")
        }
    });

//新增

webapi.safeAjax({
        type: "POST",
        url: "/_api/[表名]",
        contentType: "application/json",
        async: false,
        data: JSON.stringify(recordObj),
        success: function (res) {
            console.log(res);
        }, error: function (ex) {
            console.log(ex);
            //alert("")
        }
    });
