使用Express,我运行index.html文件,但无法正确链接css,js或图像。没有图像显示,css和js没有链接。
root
app.js
package.json
node_modules
assets
img
css
js
templates
theme1
css
fonts
img
js
index.html
about.html
services.html
news.html
contact.html
我有以下目录结构:
var express = require('express');
var app = express();
var path = require('path');
app.get('/', function(req, res) {
//res.sendFile(path.join(__dirname + '/assets/templates/theme1/index.html'));
});
app.get('/about/', function(req, res) {
res.sendFile(path.join(__dirname + '/assets/templates/theme1/about.html'));
});
app.get('/services/', function(req, res) {
res.sendFile(path.join(__dirname + '/assets/templates/theme1/services.html'));
});
app.get('/services/', function(req, res) {
res.sendFile(path.join(__dirname + '/assets/templates/theme1/news.html'));
});
app.get('/contact/', function(req, res) {
res.sendFile(path.join(__dirname + '/assets/templates/theme1/contact.html'));
});
app.listen(3000);
在app.js中:
app.get
需要更好地了解app.use
和res.sendFile
以及import matplotlib.pyplot as plt
import matplotlib.patches as patches
fig = plt.figure(1)
# create rectangles for the background
upper_bg = patches.Rectangle((0, 0.5), width=1, height=0.5,
transform=fig.transFigure, # use figure coordinates
facecolor='gray', # define color
edgecolor='none', # remove edges
zorder=0) # send it to the background
lower_bg = patches.Rectangle((0, 0), width=1.0, height=0.5,
transform=fig.transFigure, # use figure coordinates
facecolor='white', # define color
edgecolor='none', # remove edges
zorder=0) # send it to the background
# add rectangles to the figure
fig.patches.extend([upper_bg, lower_bg])
# create subplots as usual
fig.add_subplot(221)
fig.add_subplot(222)
fig.add_subplot(223)
fig.add_subplot(224)
plt.show()
全部谢谢
答案 0 :(得分:0)
所以,它不起作用,因为你并没有告诉Express提供你想要的文件(js和css等)。
首先,您要使用static middleware设置静态路由:
window.onresize=arrows;
window.onload=arrows;
function arrows(){
if(document.body.scrollHeight > window.innerHeight){
document.getElementById("arrow").style.display="block";
}else{
document.getElementById("arrow").style.display="none";
}
}
那时,资产中的所有内容都是'目录将相对于您的根URL提供。所以app.use(express.static(__dirname + '/assets'));
是它的正确网址。
