Node.js 中的 agent.maxSockets 属性

agent.maxSockets 属性定义代理可以为每个源同时打开的套接字数量。默认情况下，该值设置为无穷大。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 Infinity。

示例

创建一个名为 maxSockets.js 的文件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

ma​​xSockets.js

// agent.maxSockets method Demo example

// Importing the http & agentkeepalive module
const http = require('http');
const agent = require('agentkeepalive');

const keepaliveAgent = new agent({
   maxSockets: 100,
   maxFreeSockets: 10,
   timeout: 60000, // active socket keepalive for 60 seconds
   freeSocketTimeout: 30000, // free socket keepalive for 30 seconds
});

const options = {
   host: 'tutorialspoint.com',
   port: 80,
   path: '/',
   method: 'GET',
   agent: keepaliveAgent,
};
console.log("Max free sockets: ",keepaliveAgent.maxSockets);
console.log('[%s] agent status changed: %j', Date(),
keepaliveAgent.getCurrentStatus());

输出
