Question

Anty body确实使用javascript将文件夹中的文件名写入CSV文件我的文件夹结构是Data  +IMG     +test        -1.png        -2.png     +train        -3.png        -4.png输出 CSV 文件将是这样的Data/IMG/test/1.png     Data/IMG/train/3.png Data/IMG/test/2.png     Data/IMG/train/4.png

您只需要遍历所有文件夹并找到所有文件。您可以参考此答案来执行此操作。

当您找到所有文件的路径时，您可以将这些路径写入 csv 文件的字符串中：

const fs = require('fs');

const path = require('path');

let csvStr = "";

async function loop(startPath) {

    // Our starting point

    try {

        // Get the files as an array

        const files = await fs.promises.readdir(startPath);

        // Loop them all with the new for...of

        for (const file of files) {

            // Get the full paths

            const currentPath = path.join(startPath, file);

            // Stat the file to see if we have a file or dir

            const stat = await fs.promises.stat(currentPath);

            if (stat.isFile()) {

                console.log("'%s' is a file.", currentPath);

                // put the file into csv string

                csvStr += currentPath + ", "

            } else if (stat.isDirectory()) {

                console.log("'%s' is a directory.", currentPath);

                // enter the dictionary and loop

                await loop(currentPath);

            }

        } // End for...of

    } catch (e) {

        // Catch anything bad that happens

        console.error("We've thrown! Whoops!", e);

    }

}

// Make an async function that gets executed immediately

(async () => {

    // start loop from the path where you run node

    await loop("./");

    fs.writeFileSync("your.csv", csvStr);

})();
