如何将获取请求字符串变为可行,如果有人访问www.mypage.com/yo,我怎样才能让节点将“yo”返回到变量中?
var http = require('http');
var server = http.createServer(function (request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
var stringrequested = ??????
response.end(stringrequested);
});
// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8000);
// Put a friendly message on the terminal
console.log("Server running");

request.url
包含请求的uri:
var stringrqeuested = request.url; // /yo
如果你只想要“yo”,你可以删除这样的前导斜杠:
var stringrqeuested = request.url.substr(1); // yo
但request.url
也包含查询字符串,例如/yo?a=b&c=d
。如果你不想这样,你需要解析网址:
var stringrequested = require('url').parse(request.url).pathname; // /yo
var stringrequested = require('url').parse(request.url).pathname.substr(1); // yo
以下是documentation。
中的示例node> require('url').parse('/status?name=ryan', true)
{ href: '/status?name=ryan',
search: '?name=ryan',
query: { name: 'ryan' },
pathname: '/status' }

切断网址的第一个字符(/
):
request.url.substr(1)
