Node.js 中的 agent.maxSockets 属性
该agent.maxSockets属性定义了代理可以为每个源同时打开的套接字数。默认情况下,此值设置为Infinity。这也是“http”模块的一部分。
语法
agent.maxSockets: number
参数
上述函数可以接受以下参数-
number –这定义了代理可以拥有的并发套接字数。其默认值设置为无穷大。
示例
创建一个具有名称的文件-maxSockets.js并复制以下代码片段。创建文件后,使用以下命令运行此代码,如下例所示:
node maxSockets.js
最大套接字.js
//agent.maxSocketsmethod演示示例
// Importing the http & agentkeepalive module
const http = require('http');
const agent = require('agentkeepalive');
const keepaliveAgent = new agent({
maxSockets: 100,
maxFreeSockets: 10,
timeout: 60000, //活动套接字保活60秒
freeSocketTimeout: 30000, //空闲套接字保活30秒
});
const options = {
host: 'nhooo.com',
port: 80,
path: '/',
method: 'GET',
agent: keepaliveAgent,
};
console.log("最大空闲插槽数: ",keepaliveAgent.maxSockets);
console.log('[%s] agent status changed: %j', Date(),
keepaliveAgent.getCurrentStatus());输出结果C:\home\node>> node maxSockets.js
Max sockets: 100
