这是一个基本的例子。如果您具有产品模型（/common/models/product.json），请通过添加/common/models/product.js文件来扩展模型：
module.exports = function(Product) { Product.byCategory = function (category, cb) { var ds = Product.dataSource; var sql = "SELECt * FROM products WHERe category=?"; ds.connector.query(sql, category, function (err, products) { if (err) console.error(err); cb(err, products); }); }; Product.remoteMethod( 'byCategory', { http: { verb: 'get' }, description: 'Get list of products by category', accepts: { arg: 'category', type: 'string' }, returns: { arg: 'data', type: ['Product'], root: true } } );};这将创建以下端点示例：GET / Products / byCategory？group = computers
