Curl Basic License: Curl Agent Basic Certification

Hands-on teaching you to play with Curl proxy Basic authentication

Web developers should have encountered this situation: Curl request interface is suddenly blocked by the server to authenticate. At this timeBasic AuthorizationLike a master key, today we will break open and crumble to say how to use this key to open the door of the proxy IP.

What exactly is the principle of Basic certification?

In a nutshell.Account password base64 encryptedStuff it into the request header. For example, if you go to a delivery locker to pick up a package, you have to enter the pickup code on the screen. When the proxy server receives the request, it will check if this encrypted "pickup code" is correct.

curl -x http://ipipgo.proxy:8080 -U "username:password" http://target-site.com

Watch this space.-U parametersThe base64 encoding is done automatically, which is much easier than writing the request header manually. But beware, base64 is not an encryption that can be decoded by any online tool, so theNever use important accounts.!

Proxy IP with Basic authentication pitfalls

Three major potholes are common in real life testing:

Last week, a guy couldn't get a connection, but finally realized that he'd put the code in the@ symbolNo escaping. In this case it is recommended to go directly to ipipgo's tech support, who have a friendlier proxy error message.

Practical: using ipipgo proxy measurement style

Take ipipgo'sDynamic Residential AgentsAs an example:

curl -x http://zhuque.ipipgo.io:8921 -U "vipuser:8k9j3m2n" https://api.shop.com/products

Note here that ipipgo'sUser name rulesbeRegion + Business TypeCombination, for example, us-shopping indicates the U.S. e-commerce business agent. If you return 407, 80% of the time, you didn't choose the right region.

The QA session you've been asking about

Q：Why the access fails even though the authentication is successful?
A: Eighty percent of the proxy IP was pulled by the target site. It is recommended to change the ip ipgodynamic rotation agent, automatic IP change per request.

Q: How to manage multiple agent certifications in bulk?
A: Available.netrc filesSave the account password so you don't have to enter it every time:

machine proxy.ipipgo.io login vipuser password 8k9j3m2n

Q: How do enterprise apps play?
A: Directly on ipipgo'sAPI proxy poolThe first one is to support 5000+ concurrency at the same time and comes with failure retry and automatic node switching. Remember to add X-Proxy-Pool parameter in the request header, specifically ask their family technology to document.

Say something from the heart.

When I first started using proxy Basic certification, I was also crashed by various 407 errors. Then I switched to ipipgo and found adebug modefunction, can visualize the whole authentication process, which slowly figure out the door. Their agents also have the advantage of supportingUse both authentication methods at the same time, such as Basic+Token double insurance, suitable for scenarios with high security requirements.

Lastly, a reminder to newbies: don't pass passwords in the public network environment in plaintext! Even if you want to use Basic authentication, make sure to cooperate with theHTTPS proxyIt's a good idea to use an encrypted channel for this purpose. In this regard, ipipgo's proxy is encrypted by default, using a more solid. If you still encounter any problems, directly to their customer service, response speed than the three major carriers much faster.
