ace-express commented 7 years ago

my code:

const Etcd = require("node-etcd");

const etcd = new Etcd("http://127.0.0.1:2379");

etcd.version(console.log);

req.proxy is : { "protocol": "http:", "slashes": true, "auth": null, "host": "127.0.0.1:1235", "port": "1235", "hostname": "127.0.0.1", "hash": null, "search": null, "query": null, "pathname": "/", "path": "/", "href": "http://127.0.0.1:1235/" }

my .zshrc

export http_proxy=http://127.0.0.1:1235 export https_proxy=http://127.0.0.1:1235

etcdctl can be used normally. cause proxy i get this error:

You could always unset the variable within the script. For instance, you could set your npm start script to be:

http_proxy= https_proxy node index.js
