javascript - HAPI 17 : Routes not registered

Question

您好，我正在从 Hapi 16 迁移到 Hapi 17。我在另一个文件中定义了我的路由，我正尝试将其注册为插件。但是当我调用 API 时得到 404。路由未在服务器上注册。

这是我的服务器代码。

 'use strict'
    const Hapi = require('hapi')
    const server = new Hapi.Server({ port: 1234, host: 'localhost' });
    const plugins = [{
      plugin: require('vision'),
      plugin: require('./methods/exampleMethod'),
      plugin: require('./routes/devices')
    }]

    async function registerPlugin(){
        await server.register(plugins)
    }
    registerPlugin().then( () => {server.start()})

这是我的路由文件 devices.js:

exports.plugin = {
    register: (server, options) =>
    {
        server.routes = [{
            method: 'GET',
            path: '/v1/devices',
            handler: async function (request, h) {
                const val = server.methods.testMethod("ankur")
                const response = h.response('hello world ankur')
                response.type('text/plain')
                return response
            }
          }]
    },
    name: 'devices'
}

方法文件

exports.plugin = {
    register: (server, options) => {
        server.method(
          {
            name: 'testMethod',
            method: function (id) {
              return new Promise(function (resolve, reject) {
              return resolve("Test method called")
              })
            }
          })
    },
    name: "exampleMethod"

我正在关注 Hapi 17 的发行说明并尝试将路由注册为自定义插件。但是，当我点击 Get v1/devices 时，我得到了 404。

您的路线文件的以下代码将起作用:

 exports.plugin = {
  register: (server, options) => {
    server.route(
      {
        method: "GET",
        path: "/v1/devices",
        handler: async function(request, h) {
          //const val = server.methods.testMethod("ankur")
          const response = h.response("hello world ankur");
          response.type("text/plain");
          return response;
        }
      }
    );
  },
  name: "devices"
};

您应该使用路由对象调用 server.route() 函数。

如果你想通过你的路由插件注册多个函数，使用这样的东西:

exports.plugin = {
  register: (server, options) => {
    const routes = [
      {
        method: "GET",
        path: "/v1/devices",
        handler: async function(request, h) {
          const response = h.response("hello world");
          response.type("text/plain");
          return response;
        }
      },
      {
        method: "GET",
        path: "/v1/another",
        handler: async function(request, h) {
          const response = h.response("hello another world");
          response.type("text/plain");
          return response;
        }
      }
    ];

    
    server.route(routes);
  
  },
  name: "devices"
};

编辑:

方法插件

exports.plugin = {
  register: (server, options) => {
    server.method("testMethod", async function(id) {
        return "Test method called";
    });
  },
  name: "exampleMethod"
};

调用方法:

{
        method: "GET",
        path: "/v1/example",
        handler: async function(request, h) {
          const response = await request.server.methods.testMethod();

          return response;
        }
}
