尝试将用户添加到数据库js

Question

此代码用于将用户添加到数据库

export const addUserInDB = (userEntityModel: UserEntityModel) => {
userEntityModel.id = '7';
 return fetch(usersUrl, {
 method: 'POST',
 body: JSON.stringify(userEntityModel),
 }).then((res) => res.json());
};

但它只在数据库中返回此代码

{
  "id": "Tcvpety"
}

我想要这样的东西

{
  "id": "5",
  "login": "luigi",
  "password": "luigi125",
  "email": "lluis.rubies@test.com",
  "country": "Japan",
  "type": "Customer",
  "language": [
    "Japanese",
    "English"
  ]
},
