Node.js process.abort()用法及代碼示例


process.abort()屬性是流程模塊的內置應用程序編程接口,用於立即中止正在運行的NodeJS流程。它還會生成一個核心文件。

用法:

process.abort()

參數:此函數不接受任何參數。

返回類型:它具有void返回類型。

以下示例說明了Node.js中process.abort()屬性的用法:



範例1:

index.js


// Function to illustrate abort method
const RunWithAbort = () => {
    console.log('Start...');
  
    // It prints GeeksForGeeks after every 1 second
    setInterval((function() {
        return console.log('GeeksForGeeks');
    }), 1000);
  
    // It calls process.abort() after 5 seconds
    setTimeout((function() {
        return process.abort();
    }), 5000);
};
  
// Function to illustrate working of above function 
// without abort method
const RunWithoutAbort = () => {
    console.log('Start...');
  
    // It prints GeeksForGeeks after every 1 second
    setInterval((function() {
        return console.log('GeeksForGeeks');
    }), 1000);
};
  
// Uncomment below line to call RunWithoutAbort
// function it will run in infinitely
// RunWithoutAbort();
  
// Call RunWithAbort function
// it will abort after 5 seconds
RunWithAbort();

使用以下命令運行index.js文件:

node index.js

輸出:我們將在控製台屏幕上看到以下輸出。

Start...
GeeksForGeeks
GeeksForGeeks
GeeksForGeeks
GeeksForGeeks
Abort trap:6

範例2:

index.js


// Function to illustrate abort method
const RunWithAbort = () => {
    console.log('Start...');
  
    // It prints GeeksForGeeks after every 1 second
    setInterval((function() {
        return console.log('GeeksForGeeks:1 second');
    }), 1000);
  
    // It prints GeeksForGeeks after every 2 seconds
    setInterval((function() {
        return console.log('GeeksForGeeks:2 second');
    }), 2000);
  
    // It calls process.abort() after 5 seconds
    setTimeout((function() {
        return process.abort();
    }), 5000);
};
  
const RunWithoutAbort = () => {
    console.log('Start...');
  
    // It prints GeeksForGeeks after every 1 second
    setInterval((function() {
        return console.log('GeeksForGeeks');
    }), 1000);
};
  
// Uncomment below line to call RunWithoutAbort
// function it will run in infinitely
// RunWithoutAbort();
  
// Call RunWithAbort function
// it will abort after 5 seconds
RunWithAbort();

使用以下命令運行index.js文件:

node index.js

輸出:我們將在控製台屏幕上看到以下輸出。

Start...
GeeksForGeeks:1 second
GeeksForGeeks:2 second
GeeksForGeeks:1 second
GeeksForGeeks:1 second
GeeksForGeeks:2 second
GeeksForGeeks:1 second
Abort trap:6
