我正在尝试使用Postman上的prestashop网络服务来创建新客户。我已经将webservice更新为接受json格式的输入和输出。当我尝试创建新客户时，数据库中添加了一行，但未添加关联组ID。

我通过http://mywebsite.com/api/customers?schema=synopsis得到了空白资源，这是我得到的：

NodeJS

这是我填写表格的方式：

{
"customer": {
    "id_default_group": "","id_lang": "","newsletter_date_add": "","ip_registration_newsletter": "","last_passwd_gen": "","secure_key": "","deleted": "","passwd": "","lastname": "","firstname": "","email": "","id_gender": "","birthday": "","newsletter": "","optin": "","website": "","company": "","siret": "","ape": "","outstanding_allow_amount": "","show_public_prices": "","id_risk": "","max_payment_days": "","active": "","note": "","is_guest": "","id_shop": "","id_shop_group": "","date_add": "","date_upd": "","reset_password_token": "","reset_password_validity": "","associations": {
        "groups": [
            {
                "id": null
            }
        ]
    }
}
}

这是结果：

{
"customer": {
    "id_default_group": "3","id_lang": "1","newsletter_date_add": "0000-00-00 00:00:00","deleted": "0","passwd": "20101998","lastname": "sign up","firstname": "test","email": "asdfgh@gmail.com","id_gender": "2","birthday": "0000-00-00","newsletter": "0","optin": "0","outstanding_allow_amount": "0.000000","show_public_prices": "0","id_risk": "0","max_payment_days": "0","active": "1","is_guest": "0","id_shop": "1","id_shop_group": "1","reset_password_validity": "0000-00-00 00:00:00","associations": {
        "groups": [
            {
                "id": "3"
            }
        ]
    }
}
}

您会看到没有关联返回。

谁能告诉我我错了吗？我对prestashop很陌生。预先感谢
