RESTful api 的 CRUD 方法和端点未在代理 api 服务器中生成

Question

我正在尝试代理服务器（http://www.swapi.co/api/starships for practice, then a Salesforce api for production). This will be the mobile backend for a React Native app. I'm following the documentation here: http://loopback.io/doc/en/lb2/REST-connector.html#resource-operations。但是，当使用生成器创建使用 CRUD 操作和 Starship 模型的 'starship' 数据源时，我尝试时没有任何显示使用 built-in 浏览器探索 api。代理 RESTful API 时，我想使用 RESTful API 公开它，这甚至可以用于 Loopback 吗？

这是我用来查看 api:

的资源管理器的屏幕截图

以下是我正在执行的步骤：

$ slc loopback:datasource
? Enter the data-source name: starship
? Select the connector for starship: REST Services (supported by StrongLoop)
? Base URL for the REST service: http://www.swapi.co/api/starship
? Default options for the request: [left blank, hit enter]
? An array of operation templates: [left blank, hit enter]
? Use default CRUD mapping: (y/N) Y

$ slc loopback:model
? Enter model name: Starship
? Select data-source to attach Starship to: starship (rest)
? Select model's base class: Model
? Expose Person via the REST API? (Y/n) Y
? Custom plural form (used to build REST URL): starships
? Common model or server only? common

Let's add some Starship properties now.

Enter an empty property name when done.
? Property name: [left empty, hit enter]

$ npm start

但是，当我导航到资源管理器时，只显示用户 api，没有显示 Starships。关于我可能做错了什么的任何想法？以下是我能找到的生成文件的内容：

common/models/starship.js

'use strict';

module.exports = function (Starship) {

};

common/models/starship.json

{
    "name": "Starship",
    "plural": "starships",
    "base": "Model",
    "idInjection": true,
    "options": {
        "validateUpsert": true
    },
    "properties":  {},
    "validations":  [],
    "relations": {},
    "acls": [],
    "methods": {}
}

server/datasources.json

{
  "db": {
    "name": "db",
    "connector": "memory"
  },
  "starship": {
    "name": "starship",
    "baseURL": "http://www.swapi.co/api/starships",
    "crud": true,
    "connector": "rest"
  }
}

server/model-config.json

{ 
  ... 
  "Starship": {
    "datasource": "starship",
    "public": true
  }
}

问题是，您使用的是模型而不是 PersistedModel 作为基础。

模型没有远程访问方法。

您需要将 common/models/starship.json 更改为

{
     "name": "Starship",
     "plural": "starships",
     "base": "PersistedModel",
     "idInjection": true,
     "options": {
         "validateUpsert": true
     },
     "properties":  {},
     "validations":  [],
     "relations": {},
     "acls": [],
     "methods": {}
}
