在Web开发中，获取请求的URL（即request URL）通常取决于你使用的编程语言和框架。以下是一些常见语言和框架中获取请求URL的方法：

@app.route('/')

def index():

url = request.url

return 'Request URL: ' + url

```

Python Django

```python

from django.http import HttpResponse

def index(request):

url = request.get_full_path()

return HttpResponse('Request URL: ' + url)

```

JavaScript (Node.js)

```javascript

const http = require('http');

http.createServer((req, res) => {

let url = req.url;

res.writeHead(200, {'Content-Type': 'text/plain'
