Node.js fs.dirent.name用法及代碼示例

fs.Dirent.name屬性是文件係統模塊內的類fs.Dirent的內置應用程序編程接口，用於提供特定Dirent的名稱。

用法:

const dirent.name

參數：此屬性不接受任何參數。

返回值：此屬性返回特定Dirent的名稱。

以下示例程序旨在說明Node.js中fs.dirent.name屬性的使用：

範例1： 文件名：index.js

// Node.js program to demonstrate the  
// dirent.name property 
const fs = require('fs'); 
  
// Initiating asyn function 
async function stop(path) { 
  
    // Creating and initiating dir's  
    // underlying resource handle 
    const dir = await  
        fs.promises.opendir(path); 
  
    // Synchronously reading the dir's 
    // underlying resource handle 
    // using readSync() mehtod 
    for (var i = 0; i <= 6; i++) { 
  
        // Checking if the particular 
        // dirent is SymbolicLink or  
        // not by using name() method 
        const value = (dir.readSync()).name; 
  
        // Display the result 
        console.log(value); 
    } 
} 
  
// Catching error 
stop('./').catch(console.error);

使用以下命令運行index.js文件：

node index.js

輸出：

abcd.cer
cert.cer
certfile.cer
certificate1.cer
example.txt
features
filename.txt

範例2： 文件名：index.js

// Node.js program to demonstrate the  
// dirent.name property 
const fs = require('fs'); 
  
// Initiating asyn function 
async function stop(path) { 
  
    let dir = null; 
  
    try { 
  
        // Creating and initiating directory's 
        // underlying resource handle 
        dir = await fs.promises.opendir( 
            new URL('file:///F:/java/')); 
  
        // Synchronously reading the File's 
        // underlying resource handle 
        // using readSync() method 
        for (var i = 0; i <= 3; i++) { 
  
            // Checking if the particular dirent  
            // is File or not by using isFile() method 
            const value = (dir.readSync()).name; 
  
            // Display the result 
            console.log(dir.readSync()); 
            console.log(value); 
        } 
    } finally { 
  
        if (dir) { 
  
            // Display the result 
            console.log("dir is closed successfully"); 
  
            // Synchronously closeSyncing the  
            // directory's underlying resource handle 
            const promise = dir.closeSync(); 
        } 
    } 
} 
  
// Catching error 
stop('./').catch(console.error);

使用以下命令運行index.js文件：

node index.js

輸出：

Dirent { name:'books.txt', [Symbol(type)]:1 }
abcd.cer
Dirent { name:'certfile.cer', [Symbol(type)]:1 }
cert.cer
Dirent { name:'example.com_index.html', [Symbol(type)]:1 }
certificate1.cer
Dirent { name:'features', [Symbol(type)]:2 }
example.txt
