We can simply use thenticate() to accomplish that.Smartproxy Extension – Easy Proxy Setup Are you ready to set up proxies easily? The best proxy extension is about to hit up your browser with millions of global residential and US datacenter IP addresses. proxy-chain is not needed anymore to solve the chrome/puppeteer authentication problem.
#Proxy per tab browser how to#
Solving the problem of missing proxy authentication in chromeįor completeness sake, it is also shown how to authenticate to a proxy with puppeteer. If that is the case, the experiment was a success.

It should output the IP address metadata of two different proxy connections. proxy_server.js const Prox圜hain = require ( 'proxy-chain' ) const server = new Prox圜hain.

Therefore, we need the intermediate proxy server to have the capability to strip all headers that start with a magic string such as x-no-forward. This is not what we want, since it would leak username/passwords of the proxystring to the website we want to crawl. No, proxy-chain only supports http/s proxiesĭynamically changing proxy configuration from puppeteer codeĮven though it is possible to dynamically change the upstream proxy server in proxy-chain by setting an extra http header such as x-no-forward-upstream-proxy, this header would also be copied and sent to the upstream proxy. With pptr thenticate(), not via command line The contribution of this blog article is to enable to dynamically change http/s proxies via a modified proxy-chain module. This is the state of the art of chrome browser proxy support with puppeteer. In the remainder of the article our http/s proxy server will have the proxy string Overview What we really want is to dynamically change the browser proxy within our puppeteer code. However, the current version of proxy-chain only solves the issue with proxy authentication.
#Proxy per tab browser software#
The software is called proxy-chain and there exists a informative blog article that explains how the software works. They created it back when thenticate() was not a part of puppeteer yet and made the following scenario possible: It seems that the company Apify encountered problems with proxy authentication and thus released a intermediary nodejs proxy server that forwards proxy connections to the real proxy server. This would enforce a restart for each url, which prolongs the crawling process significantly. Some sites require a different proxy for each url. The reason is, I don't want to restart the browser each time I need to change the proxy. However, issue 1) is a mandatory requirement for me and thus needs to be solved. I don't need per page proxies anyway, since the crawling software I write runs with one browser tab at the time. It seems like the new module tries to solve this issue.įor my purposes, I don't really care about problem 3).
#Proxy per tab browser windows#
The global proxy configuration applies to all pages and windows of a launched chrome process. Per page proxies: Per page proxies are not supported with the chrome browser.Puppeteer supports the http proxy authentication via the thenticate() function, but it does not have an equivalent for socks proxies. user/pass proxy authentication: The chrome browser does not support username/password proxy authentication for socks proxies.A restart is required to switch proxy configuration. Dynamically changing proxy servers: Once the chrome browser is started, it is not possible to change the proxy configuration any longer.The most pressing issues are the following:

Chrome/Puppeteer has a couple of annoying issues when trying to use http/s proxies and socks proxies with the chrome browser controlled by puppeteer.
