Hello again, I don’t think that nobody knows how to fix this problem. please help me.
my problem is still the Access-Control-Allow-Origin error. how can I or where I have to write down the access control allow? the problem is, chromium block my request (chrome) is loaded but not chromium to display my request.
thank guys

@fischi87 this is servers rejecting requests from clients who do not have dns entries matching their IP address (cross origin)
sometimes there is a proxy server on the web that can reissue your request from a known server.
in the next MM release is a built in service that appears to do that for you.
U have to download the develop branch and add a new config parm to enable it for a module.

you provide no infos related to your problem, we are not clairvoyant

var stromRequest = new XMLHttpRequest(); var requestURL = 'http://192.168.178.44/cm?cmnd=var1'; stromRequest.onreadystatechange = function () { if (stromRequest.readyState === XMLHttpRequest.DONE) { if(stromRequest.status === 200) { var json_parse = JSON.parse(stromRequest.responseText).Var1 var stromverbrauch = Number(json_parse * 0.30)//.toFixed(2); var verbrauch = stromverbrauch.toFixed(2);
this is my request and the error:
-
so I assume the code snippet is from the module.js (not from node_helper.js). The url with IP 192.168.178.44 is pointing to another device in your network and is therefore different to the IP where mm is running?
If mm has the same IP you could try
localhost
instead, if the IP’s are different you can try this:var requestURL = location.protocol + "//" + location.host + "/cors?url=http://192.168.178.44/cm?cmnd=var1";
The 2. option with the cors url works only with the
develop
branch of mm (will be in the next official relase coming 1. April). -
thats right, its from the module.js. i read i can fix this issue with the node_helper.js but i dont know how to write the code down in the node_helper.js to get the result from my url.
i will try ur answer later.
i know how to write code in the node_helper.js form the request?
thanks

@karsten13 said in Nobody knows???:
var requestURL = location.protocol + “//” + location.host + “/cors?url=http://192.168.178.44/cm?cmnd=var1”;
now I get this error:
cannot get /cors.
