XMLHttpRequest - 相对或绝对路径? [英] XMLHttpRequest - relative or absolute path?
问题描述
我试图在本地服务器上进行 HTTP测试。
在我的 html
文件,我链接 src =scripts / scriptedHTTP.js
:
var req = new XMLHttpRequest();
req.open(GET,file.txt,false);
req.send(null);
console.log(req.responseText);
我服务于 localhost:8000
with python -m SimpleHTTPServer
。
file.txt
与 scriptedHTTP.js
http:// localhost:8000 / scriptedHTTP.html
得到我错误404
。
如果我用 node
运行 scriptedHTTP.js
,我得到 XMLHttpRequest is没有定义
。
我做错了什么?
..
XMLHttpRequest
将使用页面域构成请求路径(如果y因此在这种情况下,您只需指定 file.txt 的完整路径:
var req = new XMLHttpRequest();
req.open(GET,scripts / file.txt,false);
req.send(null);
console.log(req.responseText);
请注意, XMLHttpRequest
是web因此浏览器在 NodeJS
中不可用
I'm trying to make HTTP
tests in my local server.
On my html
file, I link src="scripts/scriptedHTTP.js
:
var req = new XMLHttpRequest();
req.open("GET", "file.txt", false);
req.send(null);
console.log(req.responseText);
I serve on localhost:8000
with python -m SimpleHTTPServer
.
file.txt
is on the same path as scriptedHTTP.js
http://localhost:8000/scriptedHTTP.html
gets me Error 404
.
if I run scriptedHTTP.js
with node
, I get XMLHttpRequest is not defined
.
what I am doing wrong?
any help much appreciated..
XMLHttpRequest
will form the request path using the page domain (if you don't set it manually), so in this case you just need to specify the complete path of your file.txt:
var req = new XMLHttpRequest();
req.open("GET", "scripts/file.txt", false);
req.send(null);
console.log(req.responseText);
Note that XMLHttpRequest
is a feature of web browsers so is not available in NodeJS
