Firebase云功能:onRequest和onCall之间的区别 [英] Firebase Cloud Functions: Difference between onRequest and onCall

问题描述

浏览文档时，我遇到了

...您可以直接通过HTTP请求或客户端的调用来调用函数.

〜源

有(引号中的链接)是有关functions.https.onCall的提及.

但是在教程此处中，使用了另一个功能functions.https.onRequest，所以我应该使用哪一个?为什么?它们之间的区别/相似之处是什么?

But in the tutorial here, another function functions.https.onRequest is used, so which one should I use and why? What is the difference/similarity between them?

functions.https的文档位于此处.

推荐答案

官方文档

The official documentation for those is really helpful, but from the view of an amateur, the described differences were confusing at first.

• 这两种类型，在部署时均分配有唯一的HTTPS终结点URL，并且可以直接访问.

• Both types, when deployed, are assigned with a unique HTTPS endpoint URL and can be accessed directly.

• 可以直接从客户端应用程序调用(这也是主要目的).

• Can be invoked (and this is also the main purpose) directly from the client app.

functions.httpsCallable('getUser')({uid})
  .then(r => console.log(r.data.email))

它由用户提供的data和 automagic context实现.

It is implemented with user-provided data and automagic context.

export const getUser = functions.https.onCall((data, context) => {
  if (!context.auth) return {status: 'error', code: 401, message: 'Not signed in'}
  return new Promise((resolve, reject) => {
    // find a user by data.uid and return the result
    resolve(user)
  })
})

context自动包含有关请求的元数据例如uid和token.

输入data和response对象会自动(反)序列化.

The context automagically contains metadata about the request such as uid and token.

Input data and response objects are automatically (de)serialized.

• Firebase onRequest文档
• 主要用作Express API端点.

• 它由明确的Request和Response对象实现.

• Firebase onRequest Docs
• Serves mostly as an Express API endpoint.

• It is implemented with express Request and Response objects.

export const getUser = functions.https.onRequest((req, res) => {
  // verify user from req.headers.authorization etc.
  res.status(401).send('Authentication required.')
  // if authorized
  res.setHeader('Content-Type', 'application/json')
  res.send(JSON.stringify(user))
})

取决于用户提供的授权标头.

您负责输入和响应数据.
