How to use DocumentDB behind a Proxy in NodeJS

问题

In NodeJS I`m trying to connect to a Cosmos DB using the Documentdb library, as the getting starter of the azure documentation says in the TODO List Example. Tutorial Here

If I use an Internet that is not behind a proxy it works.

This is the connection code:

var DocumentDBClient = require('documentdb').DocumentClient;

var docDbClient = new DocumentDBClient(config.host, {
    masterKey: config.authKey
});

But when I'm behind a proxy, the connection never occur's. I`m getting an "Error: connect ETIMEDOUT"

In other node JS apps, if I want to make a request of a webservice, I just configure the proxy for the request. For example with request:

request = require('request').defaults({
  proxy:'http://USERNAME:PASSWORD@proxy.url.com:8080',
});

Is there a way to configure the proxy in DocumentDB to connect to the DB in Azure (NodeJS)?

回答1:

I've not personally tried it but I was going through the source code of the SDK and found out that ConnectionPolicy has a parameter called ProxyUrl. Can you try something like the following:

var connectionPolicy = new DocumentBase.ConnectionPolicy();
connectionPolicy.ProxyUrl = 'http://USERNAME:PASSWORD@proxy.url.com:8080';
var docDbClient = new DocumentDBClient(config.host, {
    masterKey: config.authKey
}, connectionPolicy);
