JavaScript Websocket only works on localhost -


can tell me how use javascript create wss connection remote ip address?

my websocket works on 127.0.0.1 , localhost

ws = new websocket("wss://127.0.0.1:13529"); ws.onopen = function() {   alert("连接成功");   ws.send('tom');   alert("给服务端发送一个字符串：tom");};   ws.onmessage = function(e) {   alert("收到服务端的消息：" + e.data); };

after change 127.0.0.1 ip address, connection cannot established.

i found post why did failed connect websocket?.

it says setting '0.0.0.0' can solve problem. however, changed codes following, cannot run.

enter image description here

the error message is: 

uncaught syntaxerror: unexpected identifier

i install ssl cert: install ssl cert

websockets not going standardized raw socket support.

or more raw socket portions needed directly communicate between 2 browsers without need of host server reform data.

but answer question, within google web apps (to discontinued 2018 per chrome press release) have web server running websockets using this code / web app (web server chrome offered chromebeat.com) allows other systems access web server. i've not examined code.

given bad news suggest using nodejs.

https://www.w3.org/tr/websockets/ current published.

following http procedures here introduce serious security problems in web browser context. example, consider host websocket server @ 1 path , open http redirector @ another. suddenly, script can given particular websocket url can tricked communicating (and potentially sharing secrets with) host on internet, if script checks url has right hostname.

https://w3c.github.io/websockets/ development

no 1 in web platform working group actively working on specification. latest version of websocket api use whatwg living standard.

https://html.spec.whatwg.org/multipage/web-sockets.html#network

to enable web applications maintain bidirectional communications server-side processes, specification introduces websocket interface.

this interface does not allow raw access underlying network. example, interface not used implement irc client without proxying messages through custom server.

the web server requires raw access sockets :(

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
