我正在尝试创建一个显示文件树的网页。我选择使用此网站上的jqueryFileTree：http://www.abeautifulsite.net/blog/2008/03/jquery-file-tree/
最终，我将把这棵树挂到服务器上。但是，现在，我正在尝试在运行Node.js localhost的Windows机器上运行它。
由于这个jquery插件需要使用连接器脚本（为了能够提取目录信息），我选择使用它们包含的python连接器脚本jqueryFileTree.py。
我的问题是localhost告诉我无法找到python脚本（错误404）。但是，我知道我已经为文件提供了正确的路径，因为当我将URL输入浏览器时，我可以下载脚本。这种行为让我失望，因为它告诉我一件事，但做另一件事。
以下是我的所有相关代码和信息。
目录结构：
|-public (localhost)
|-connectors
|-jqueryFileTree.py
创建jqueryFileTree对象：
$(window).load(
function()
{
$('#fileTree').fileTree({
root: '/',
script: 'connectors/jqueryFileTree.py',
expandSpeed: 500,
collapseSpeed: 500,
multiFolder: true
},
function(file)
{
alert(file);
});
});
这是我的错误消息：
Failed to load resource: the server responded with a status of 404 (Not Found): http://localhost:3700/connectors/jqueryFileTree.py
以下是jqueryFileTree和连接器脚本的代码。我没有写代码。当你从我之前提到的网站下载插件时，就会发生这种情况。

连接器脚本代码：
#
# jQuery File Tree
# Python/Django connector script
# By Martin Skou

import os
import urllib
def dirlist(request):
r=['<ul class="jqueryFileTree" style="display: none;">']
try:
r=['<ul class="jqueryFileTree" style="display: none;">']
d=urllib.unquote(request.POST.get('dir','c:\\temp'))
for f in os.listdir(d):
ff=os.path.join(d,f)
if os.path.isdir(ff):
r.append('<li class="directory collapsed"><a href="#" rel="%s/">%s</a></li>' % (ff,f))
else:
e=os.path.splitext(f)[1][1:] # get .ext and remove dot
r.append('<li class="file ext_%s"><a href="#" rel="%s">%s</a></li>' % (e,ff,f))
r.append('</ul>')
except Exception,e:
r.append('Could not load directory: %s' % str(e))

尝试一件事：使用此路径'connectors / jqueryFileTree.py'尝试使用浏览器中的绝对URL来下载脚本。

请原谅我没有查看您的脚本并提供延迟回复。但是，我遇到了同样的问题并相信通过遵循以下所述的路径解决了问题：http://pastebin.com/kVkTssdG和http://www.abeautifulsite.net/jquery-file-tree/
详细说明： 1）我创建了一个名为＆＃39; jQFTree＆＃39;的新文件夹。在我的项目的node_modules＆＃39;子文件夹。 2）我包括行：
var jQFTree=require('jQFTree');
和
app.post('/FileTree', jQFTree.handlePost);
到node.js中的app.js文件 3）添加到我的表格＆nbsp; html：
div(id="FileTree" class="fTre")
和脚本：
var orig = window.location.origin + '/FileTree';
var servDir='Mats';//or Carps or Rugs
$("#FileTree").fileTree({
root: servDir,
script: orig
},
followed by callback function.
4）之前创建的jQFTree文件夹只包含一个名为＆＃39; index.js＆＃39;以下javascript代码：
//my Node.js module for jQuery File Tree
var path = require('path');
var fs = require('fs');
var util = require('util');
var stringHeader = "<ul class='jqueryFileTree' style='display: none;'>";
var stringFooter = "</ul>";
// arguments: path, directory name
var formatDirectory =
"<li class='directory collapsed'><a href='#' rel='%s/'>%s</a><li>";
// arguments: extension, path, filename
var formatFile = "<li class='file ext_%s'><a href='#' rel='%s'>%s</a></li>";
var createStatCallback = (function (res, path, fileName, isLast) {
return function (err, stats) {
if (stats.isDirectory()) {
res.write(util.format(formatDirectory, path, fileName));
}
else {
var fileExt = fileName.slice(fileName.lastIndexOf('.') + 1);
res.write(util.format(formatFile, fileExt, path, fileName));
}
if (isLast) {
res.end(stringFooter);
}
}
});
exports.handlePost = function (req, res) {
//for safety; only directory name is available from the browser
//through the req.body.dir variable
//but complete dir path in server is required for dir browsing
// 'text/html'
//console.log('Filetree handles post dir: '+ req.body.dir);
res.writeHead(200, { 'content-type': 'text/plain' });
res.write(stringHeader);
// get a list of files
var seeDir = req.body.dir;
if (seeDir.indexOf('%5C') > -1 || seeDir.indexOf('%2F') > -1) {
//directory path was returned as a subfolder from jQuery FileTree using URL encoding
//decode it first:
seeDir = decodeURIComponent(seeDir);
//console.log('seeDir: '+seeDir+' __dirname:'+__dirname);
if (seeDir.slice(-1) == "/" || seeDir.slice(-1) == "\\") {
//last char either / (MS-windows) or \ (not MS-windows) is dropped
seeDir = seeDir.slice(0, seeDir.length - 1)
if (seeDir.indexOf('/') > -1) {
seeDir = seeDir + '/';
}
else {
seeDir = seeDir + '\\';
}
}
}
if (req.body.dir == 'Mats' || req.body.dir == 'Carps' || req.body.dir == 'Rugs') {
//restricted to three sub dirs in server directory: public/MatsCarpsRugs/
//console.log('.=%s', path.resolve('.'));
//gives path to the above app.js calling this module (=as wanted)
//combine path to requested directory:
seeDir = path.join(path.resolve('.'), 'public', 'MatsCarpsRugs', req.body.dir);
if (seeDir.indexOf('/')>-1){
//web-browser not in ms-windows filesystem
seeDir=seeDir+'/';
}
else{
//web-browser is in ms-windows filesystem
seeDir=seeDir+'\\';
}
//console.log('seeDir now: '+seeDir);
}
fs.readdir(seeDir, function (err, files) {
var fileName = '';
var path = '';
var statCallback;
if (files.length === 0) {
path = util.format('%s%s', seeDir, fileName);
statCallback = createStatCallback(res, path, fileName, true);
fs.stat(path, statCallback);
}
for (var i = 0; i < files.length; i++) {
fileName = files[i];
path = util.format('%s%s', seeDir, fileName);
var isLast = (i === (files.length - 1));
statCallback = createStatCallback(res, path, fileName, isLast);
fs.stat(path, statCallback);
}
});
}
我希望这可以帮助您或其他人找到解决方案

我认为你的问题在于：
script: 'connectors/jqueryFileTree.py',
您的javascript在前端（用户浏览器）上执行，无法查看python文件（在服务器上）。
相反，您应该放置Django视图可用的URL。检查Django网址路由机制（https://docs.djangoproject.com/en/1.11/topics/http/urls/）以查找与您的视图相关联的网址（“dirlist”）。
