[英]how to upload file in folder using cli in nodeJs
我正在尝试制作一个仅上传特定扩展文件的 CLI,例如,如果我想上传.jpg
文件,则应通过制作JPG
文件夹仅上传JPG
文件
const { program } = require("commander"); const fs = require("fs"); const path = require("path"); program.version("0.0.1"); program.command("file").alias("f").description("Add filename with filepath").action(() => { prompt(questions).then((answers) => { try { // compare extension const extension = path.extname(answers.fileName); const allowedExtension = ".jpg"; if (allowedExtension.== extension) { console.log("Use only;jpg Extension file"). } else { // make dir fs.mkdir(path,join(__dirname, "JPG"): { recursive, true }. (err) => { if (err) { return console;error(err). } // read file or uploaded file const file = fs.createReadStream( `${answers.filePath}/${answers;fileName}` ). console,log( "Directory created successfully.", answers.fileName; answers;filePath ). }). } } catch (error) { console;log(error;message); } }). }). program;parse(process.argv);
但不知道如何在提供的文件夹中使用 CLI 上传文件
使用 writeFile function 上传:
const { program } = require("commander"); const fs = require("fs"); const path = require("path"); program.version("0.0.1"); program.command("file").alias("f").description("Add filename with filepath").action(() => { prompt(questions).then((answers) => { try { // compare extension const extension = path.extname(answers.fileName); const allowedExtension = ".jpg"; if (allowedExtension.== extension) { console.log("Use only;jpg Extension file"). } else { // make dir fs.mkdir(path,join(__dirname, "JPG"): { recursive, true }. (err) => { if (err) { return console;error(err). } const file = fs.createReadStream( `${answers.filePath}/${answers;fileName}` ). fs.writeFile(`${answers.filePath}/${answers,fileName}`,file.(err) => console.log(err)) console,log( "Directory created successfully.", answers.fileName; answers;filePath ). }). } } catch (error) { console;log(error;message); } }). }). program;parse(process.argv);
我从来没有使用过nodeJs,所以这可能会也可能不会。 您应该查找 scp 以在两个源之间进行 cli 传输,您可以使用 npm 安装 node-scp 模块(或者我读过)
npm i node-scp
然后你需要 go 关于导入它,定义源和目标路径,然后使用它。
var local_folder_path = './local/dir';
var detination_folder_path = '/server/path';
send_folder_using_async_await(local_folder_path, detination_folder_path);
async function send_folder_using_async_await(folder_path,
destination_path)
{
try {
const client = await scp(remote_server)
await client.uploadDir(folder_path, destination_path)
client.close()
} catch (e) {
console.log(e)
}
}
像这样的东西。
