Proxy api acquisition: free IP pool interface call step-by-step details

Practical instructions for proxy IP pool interface calls

Many people engaged in data collection have encountered the situation of IP blocked, this time to rely on proxy IP pool to save the day. Today we will break open the crumbs to talk about, how to call the free IP pool through the interface (to the industry's well-known ipipgo service as an example), to ensure that you can get started after reading the operation.

I. Pitfalls that are easy to step on when registering an account

When registering on the ipipgo websiteVerify Email SessionNever use QQ mailbox! Their system does not support some of the domestic mailboxes very well, the actual test with gmail or enterprise mailbox can receive the activation link in seconds. If you can't receive the verification email, go to the trash first, it will be taken as an advertisement.

Don't rush to call the interface after successful registration, first go to the background to put theAPI whitelistingSetting up. A lot of novice call failure is because there is no binding server IP, ipipgo in this aspect of the security policy is more stringent, not tied to the whitelist directly return 403 error.

Second, the interface call core parameters in detail

Highlight.Doorway for selecting protocol typesIf the target website is https encrypted, remember to choose https protocol. Although socks5 is theoretically universal, but some sites will detect the protocol type, this time with the wrong protocol even if the IP is normal will be intercepted.

Third, the secret of preserving the freshness of dynamic IP pools

The average survival time of ipipgo's residential IP pool is 3-6 hours, but real-world testing has found thatHigh-frequency use extends survivalThere is a wild way: every 15 minutes with the same IP to send a HEAD request (without catching data), can make the target site feel that the IP is "active users", but not easy to trigger the ban. There is a wild way: every 15 minutes with the same IP to send a HEAD request (do not catch data), can make the target site think that this IP is an "active user", but it is not easy to trigger the ban.

Don't panic when your IP suddenly fails, call thereplace interfaceYou can replace the current failed IP without any loss. note that this interface should be used when the original IP returns to 503 status, don't abuse it or it will be limited to call frequency.

IV. Performance Optimization Easily Overlooked

Add aIntelligent retry mechanismIt can improve the collection efficiency of more than 20%. It is recommended to set up this way: the first request timeout 3 seconds, the second time to cut the new IP and so on 5 seconds, the third time to directly change the country pool. ipipgo's response time is about 800ms on average, if it is more than 1.5 seconds, it is recommended to give up the current IP directly.

Remember to do IP caching locally, so you don't have to tune the interface to get a new IP every time.LRU algorithmMaintain a local pool and store the validated available IPs for cyclic use. When the remaining IP in the cache pool is less than 30% and then call the interface to replenish, so as to save the number of API calls and improve efficiency.

QA First Aid Kit

Q: What is the case when a call to an interface returns blank?
A: Ninety percent is the parameter format is not correct, check whether to use the Chinese comma? All parameters should use English symbols, numbers without quotation marks

Q: What should I do if all the extracted IPs cannot be connected?
A: First ping the gateway IP to see if it is a problem with your network. If the local network is normal, submit a work order in the ipipgo background to ask for adiagnostic keyThe technical team is able to track IP status in real time

Q: What if I need to use IPs from different countries at the same time?
A: In the country parameter, use vertical line to separate, for example, country=us|jp|gb, it supports up to 5 countries to mix and match. However, it is recommended to call different country pools separately for higher stability

One hidden advantage of ipipgo is thatprotocol stack depth customization </ strong, their socks5 protocol supports TCP_NODELAY parameter, in the need for low latency scenarios (such as real-time data), the delay can be pressed to 300ms or less. This is rarely seen in other platforms, is considered a technical highlight.
