你好，我正在尝试通过sugarcrm中的以下代码调用一个自定义API：

({
    extendsFrom: 'RowactionField',

    defaultFirsName: 'first_name',
    defaultLastName: 'last_name',

    initialize: function (options) {
        this._super('initialize', [options]);

        this.def.first_name = _.isEmpty(this.def.first_name) ? this.defaultFirsName : this.def.first_name;
        this.def.last_name = _.isEmpty(this.def.last_name) ? this.defaultLastName : this.def.last_name;
    },
    /**   * Rowaction fields have a default event which calls rowActionSelect     */
    rowActionSelect: function () {
        this.upper_name();
    },

    upper_name: function () {
        var first = this.model.get(this.def.first_name);
        var last = this.model.get(this.def.last_name);
        var fullName = first + last;

        if (fullName) {
            app.alert.show('name-check-msg', {
                level: 'success',
                messages: 'Firstname and Lastname filled.',
                autoClose: true
            });
        }
        else {
            app.alert.show('name-check-msg', {
                level: 'error',
                messages: 'First name and last name must be filled.',
                autoClose: false
            });

        }

        var self = this;
        url = app.api.buildURL('Leads', 'UpperName', null, {
            record: this.model.get('id')
        });

        app.api.call('GET', url, {
            success: function (data) {
                app.alert.show('itsdone', {
                    level: 'success',
                    messages: 'Confirmed to uppercase name.',
                    autoClose: true
                });
            },
            error: function (error) {
                app.alert.show('err', {
                    level: 'error',
                    title: app.lang.getAppString('ERR_INTERNAL_ERR_MSG'),
                    messages: err
                });
            },
        });
    }
})

名称为“uppernamebutton.js”，其函数为，它检查名字和姓氏是否为空，并显示错误消息以填充字段，然后调用API以大写姓名的第一个字母。
下面是自定义API的代码，我将其命名为“UpperNameApi.php”：

<?php

class UpperNameApi extends SugarApi
{
    public function registerApiRest()
    {
        return array(
            'UpperNameRequest' => array(
                //request type
                'reqType' => 'POST',

                //endpoint path
                'path' => array('Leads', 'UpperName'),

                //endpoint variables
                'pathVars' => array('module',''),

                //method to call
                'method' => 'UpperNameMethod',

                //short help string to be displayed in the help documentation
                'shortHelp' => 'Example endpoint',

                //long help to be displayed in the help documentation
                'longHelp' => 'custom/clients/base/api/help/MyEndPoint_MyGetEndPoint_help.html',
            ),
        );
    }

    public function UpperNameMethod($api, $args)
    {
        if (isset($args['record']) && !empty($args['record'])) {
            $bean = BeanFactory::getBean('Leads', $args['record']);

            if (!empty($bean->id)) {
                $first = $bean->first_name;
                $first = ucwords($first);
                $bean->first_name = $first;

                $last = $bean->last_name;
                $last = ucwords($last);
                $bean->last_name = $last;
                $bean->save();
            }

            return 'success';
        }

        return 'failed';

    }

}

请帮助那些天才程序员。
