Node.js http2session.state 方法

http2session.state() 方法用于检索当前 HTTP/2 会话的状态。它返回一个对象,该对象描述了会话的属性,例如流的数量和打开的流的状态。

语法
const state = session.state();
参数

无参数。

返回值

返回一个对象,该对象描述了会话的属性,例如流的数量和打开的流的状态。

示例

以下示例演示如何使用 http2session.state() 方法:

const http2 = require('http2');
const fs = require('fs');

const server = http2.createSecureServer({
  key: fs.readFileSync('localhost-privkey.pem'),
  cert: fs.readFileSync('localhost-cert.pem')
});

server.on('stream', (stream, headers) => {
  // 处理数据
});

server.listen(8443);

const session = server.http2connections.values().next().value.session;
const state = session.state();

console.log('当前 HTTP/2 会话状态:', state);
结果

以上代码的输出将类似于以下内容:

当前 HTTP/2 会话状态: {
    backingStream: null,
    clearText: false,
    destroyed: false,
    encrypted: true,
    error: null,
    finalSent: false,
    halfCloseTime: null,
    headersSent: false,
    http2Session: [Circular],
    inflightWindowUpdate: false,
    localWindowSize: { safeInteger: [Getter/Setter] },
    nextStreamID: 1,
    openStreams: Map {},
    options: {},
    pendingSettingsAck: false,
    pipeline: [],
    pushed: new Map(),
    receivedGoAway: false,
    receivedSettings: { settings: [Object] },
    remoteClosing: false,
    remoteSettings: { settings: [Object] },
    sentControlFrames: [],
    shutdownTimer: null,
    state: 'OPEN',
    totalBytesReceived: 0,
    totalBytesSent: 0
  }

其中包含了当前 HTTP/2 会话的所有状态信息。
