This article will explain in detail how to add verification to the API using http proxy. Xiaobian thinks it is quite practical, so share it with you as a reference. I hope you can gain something after reading this article.

In fact, when we look for domestic proxy ip providers, we inevitably encounter so-called free proxies, especially http proxies. So how did the free http proxy come about?

In fact, these IPs are agents that crawl through the public network. As far as I know, most IPs are crawlers crawling other people's websites, or ip obtained by sniffing and scanning other people's servers, and then hanging on their websites, claiming that they provide free resources, but most of them are actually unavailable. Some companies even sell this resource directly. Even if this method works, the network speed will not work properly.

The reason for adding authentication mechanisms is to prevent the resources you buy from being stolen by such unscrupulous merchants; because different users have different network topologies. Here are three common validation methods:

1. Add white list.

After adding the whitelist, only IP in the whitelist can be used. This verification method is not suitable for users whose exit ip will change;

2. Extracting the IP of the proxy should be the same as using the proxy.

If the IP of the extracted proxy is 1, the IP of the proxy used must also be 1, otherwise it cannot be used, even if your IP will change, it does not matter; as long as the extracted IP is consistent with the IP used, it can be used. However, if the change is too frequent, the IP will change immediately after extraction, and the proxy will not be used. Therefore, this verification method is not applicable to frequent changes;

When using proxy: Add the following field to the http/https request header:Proxy-Authorization:Basicuser_name:password\r.

This way you can use it no matter how your ip changes. Of course, the most important thing is to prevent your account password from being leaked. If there is such a situation, please contact ip agent should contact technical personnel, modify the password.
