如何将 Node.JS Apollo Server 连接升级到 HTTPS 或 HTTP2？

Question

如何将连接升级到 HTTP 或 H2？ 我正在运行阿波罗服务器，并且希望能够升级到安全连接。我已经生成了自签名证书。这是我的 server.js 文件的代码。

const {ApolloServer} = require("apollo-server");
const { resolvers } = require("./graphql/resolvers");
const FileSystem = require("node:fs/promises");

//Define function
async function startServer(){
  //Read file as text
  const typeDefs = await FileSystem.readFile("./graphql/type-defs.graphql",{
    encoding: 'utf-8',
  });
  const server = new ApolloServer({
    typeDefs,
    resolvers,
  });
  
  server.listen(8080).then(({url})=>{
    console.log(`The API is running at ${url}`);
  });
}
//Call the start server function
startServer();

要将 Apollo 服务器升级为使用 HTTPS 或 HTTP/2，您需要对代码进行一些调整以包含 SSL/TLS 选项并指定必要的证书和密钥文件。

以下是修改 server.js 文件以启用具有自签名证书的 HTTPS 的方法：

const { ApolloServer } = require("apollo-server");
const { resolvers } = require("./graphql/resolvers");
const FileSystem = require("node:fs/promises");
const https = require("https");

// Define function
async function startServer() {
  // Read file as text
  const typeDefs = await FileSystem.readFile("./graphql/type-defs.graphql", {
    encoding: "utf-8",
  });

  const server = new ApolloServer({
    typeDefs,
    resolvers,
  });

  // Load SSL/TLS certificate and key
  const options = {
    key: await FileSystem.readFile("path_to_your_private_key.key"),
    cert: await FileSystem.readFile("path_to_your_certificate.crt"),
  };

  // Create HTTPS server
  const httpsServer = https.createServer(options, server);

  httpsServer.listen(443, () => {
    console.log("The API is running over HTTPS at port 443");
  });
}

// Call the start server function
startServer();

将“path_to_your_private_key.key”和“path_to_your_certificate.crt”替换为您的自签名证书和私钥文件的路径。

如果你想使用HTTP/2，你可以以类似的方式利用http2模块。只需将 https 替换为 http2 并使用 createSecureServer 而不是 createServer 即可。
