推荐答案
源
对于任一客户端的JavaScript解决方案，端或服务器端，可以使用Node.js；但是，
Sources
For a JavaScript solution for either client-side or server-side, you can use Node.js; however,
- 客户端需要一个名为： NWJS的包，在此处可用： http://nwjs.io/
- 仅服务器端需要 Node.js在此处可用： https://nodejs.org
- client side requires a package called: "NWJS" available here: http://nwjs.io/
- server side only requires "Node.js" available here: https://nodejs.org
您可以找到有关这两个 JavaScript中任何一个的大量文档。解决方案；但是，还有其他 JavaScript可以使用NodeJS解决方案。
You can find extensive documentation on either of these "JavaScript" solutions; however, there are other "JavaScript" solutions available, NodeJS is very popular.
如果您在服务器上使用其他语言（如PHP），则可以在此处找到有关它的更多信息： http://php.net
If you work with another language on the server, like PHP, you can find more info about it here: http://php.net
以下内容描述了一个JavaScript解决方案，其中包含服务器端代码，您只需复制&粘贴并修改以满足您的需求。
The following describes a JavaScript solution with code for server-side that you can just copy & paste and modify to your needs.
这假定您在Linux上运行NodeJ，并且文件/文件夹（路径）不是递归的。以下示例未经测试，请随时进行测试&
This assumes you are running NodeJs on Linux and that the file/folder (path) is not recursive. The example below is not tested, feel free to test & fix as necessary.
用于与服务器端交互的客户端代码。下面的示例创建一个HTML表单，该表单使用： method = PUT 和 vars 所需的字段; -或者-使用AJAX方法来完成相同的操作。
For the client-side code interacting with the "server-side" example below, create an HTML form that uses: method="PUT" and the fields as required by the vars; -OR- use an AJAX method to accomplish the same.
let http = require('http');
//File System package...
let fsys = require('fs');
let makePath = function(root, path, data)
{
try
{
fsys.accessSync(root, fsys.W_OK);
}
catch(err)
{
return {code:403, text:'Forbidden'}
}
path = ((path[0] == '/') ? path.substr(1, path.length) : path);
if (path.split('/').length > 2)
{ return {code:412, text:'Precondition Failed'}; }
if (fsys.existsSync(path))
{ return {code:409, text:'Conflict'}; }
if (path[path.length -1] == '/')
{ fsys.mkdirSync(root +'/'+ path.substr(0, path.length -2)); }
else
{ fsys.writeFileSync((root +'/'+ path), (data || ' '), 'utf8'); }
return {code:200, text:'OK'};
};
http.createServer
(
function(request, response)
{
let vars = url.parse(request.url);
if (path && (path.indexOf('/') > -1) && (request.method == 'PUT'))
{
var resp = makePath(__dirname, vars.path, vars.data);
response.statusCode = resp.code;
response.setHeader('Content-Type', 'text/plain');
response.end(resp.text);
}
}
).listen(8124);
用法
您可以从您的Web浏览器（如果服务器在同一台计算机上运行），则在Web浏览器的地址栏中键入： http://127.0.0.1:8124 并按Enter /返回；但是，请参阅正确的NodeJS文档，以提供必要的客户端HTML&如前所述的JavaScript。
Usage
You can access this from your web browser, if your server runs on the same machine, in your web-browser's address bar type: http://127.0.0.1:8124 and hit enter/return; however, please see the proper NodeJS documentation for serving the necessary client-side HTML & JavaScript as mentioned.
