让Hapi仅注册一次@ Hapi/Good插件 [英] Get Hapi to Register @Hapi/Good Plugin Only Once

问题描述

Hapi(v17& 18)指出，我可以在server.register上指定一个选项，以使该插件一次初始化一次，而不管该插件调用server.register的次数如何-

Hapi (v17 & 18) states that I can specify an option on server.register to make the plugin on get initialized once, regardless of however many times server.register is called with that plugin - link to docs. However, I have been unable to get this to work.

我尝试将options元素放在传递给server.register的对象上.当我尝试运行服务器时，出现错误[1] "once" conflict with forbidden peer "options".这使我相信它必须放在options对象中.

I have tried putting options an element on the object that gets passed into server.register. When I try to run the server, I get the error [1] "once" conflict with forbidden peer "options". This leads me to believe that it must go in the options object.

await server.register({
    plugin: require('@hapi/good'),
    options: { /* omitted */ },
    once: true
  });

我尝试将其添加到传递到server.register的选项对象中.但是，出现此错误[1] "once" is not allowed.

I try to add it to the options object that gets passed into server.register. However, I get this error [1] "once" is not allowed.

await server.register({
    plugin: require('@hapi/good'),
    options: {
      once: true,
      /* omitted */
    },
  });

除了这个 github问题.但是，这仅涵盖了routes.

I have not been able to find an example of this option anywhere online besides this github issue. However, that only covers the routes.

推荐答案

@hapi/good使用Joi检查可以将哪些有效选项传递给插件.请在源代码中此处中进行阅读.似乎@hapi/good禁止使用routes和once，因为默认情况下它拒绝除允许的实体之外的所有实体.不过，这似乎是一个问题，因为once是服务器的插件配置，而不是插件的配置.

@hapi/good uses Joi to check what valid options can be passed in to the plugin. Check be read here in the source code. It seems that @hapi/good prohibits the use of routes and once because it denies all except the allowed entities by default. This seems to be an issue though because once is a configuration of the plugin for the server - not for the plugin.
