API Getting Started Guide: Proxy IP in API Calls

Have you figured out the relationship between proxy IPs and APIs?

Many newbies to API development always wonder:Why does my interface call keep failing?In fact, eighty percent is not dealt with the problem of IP restrictions. Now a little more formal platform are preventing robots from accessing, you take a fixed IP repeatedly adjust the interface, not block you block who? At this time it is necessary to proxy IP to act as a "stand-in actor", so that the server thinks that each time is a different user in the operation.

To give a real example, an e-commerce platform's price monitoring system, if you use a single IP to request dozens of times a minute, within half an hour quasi-hacked. But if you rotate the IP through ipipgo's dynamic proxy pool, you can continue to get stable data. This is like guerrilla warfare, change a vest to continue to work, the server simply can not tell who is who.

Practical operation manual: hand to teach you to take over the agent

Let's get right to the hard stuff and see how we can embed a proxy IP in our code. in Python, for example, it's as simple as that with the requests library:

import requests

proxies = {
    'http': 'http://user:pass@gateway.ipipgo.com:9020',
    'https': 'http://user:pass@gateway.ipipgo.com:9020'
}

response = requests.get('https://api.example.com/data', proxies=proxies)

There are three key points to note here:
1. Proxy address do not write the wrong, ipipgo's user interface has ready access to the documentation
2. Authentication information to fill in their own account
3. Remember to deal with anomalies and network fluctuations from time to time

Five Iron Rules for Choosing a Proxy Service Provider

The market is a mixed bag of agency service providers, remember these guidelines for avoiding pitfalls:
①Survival rate >90% is only reliable | Don't exceed 2 seconds response time.
③ Must support HTTPS protocol | ④ Have a failure retry mechanism
⑤ It's better to pay by the amount without wasting

I have to brag about ipipgo's service here, their home-uniqueIntelligent Routing AlgorithmIndeed, there are two brushes. Last time I did a crawler project, 500 threads were opened at the same time during the peak period, and the success rate of IP switching was still able to stay above 95%, which is indeed more stable than the previous ones.

Frequently Asked Questions First Aid Kit

Q: What should I do if my proxy IP is not working?
A: Normal phenomenon, it is recommended to set the frequency of automatic change. ipipgo SDK has a ready-made rotation mechanism, set every 5-10 requests to change the IP on the line.

Q: What should I do if I encounter a certificate error?
A: 80% of the proxy environment is not configured properly, check whether the CA certificate is missing. If you really can't do it, you can look for ipipgo's technical support, they are online 24 hours a day!

Q: How can I tell if a proxy is in effect?
A: There is a tricky way, first without the proxy to adjust an interface to check the IP, and then use the proxy to adjust once, compare the two IP addresses are different!

Advanced Play: Playing the Agent Out

That's how veteran drivers use proxies:
1. Geographic orientationFor example, connecting to a logistics API requires the IP of a specific city.
2. Flow sharing: Spread large concurrent requests to different outlets
3. failover: Main IP blocked automatically switch to alternate channel
4. Performance Monitoring: Record the success rate of each IP to do quality analysis

I've been using ipipgo lately.City-level location agentsDid a data aggregation of local life services, specializing in grabbing information about merchants in different cities. Their IP resources are really rich, even the third and fourth tier cities can be covered, this point many service providers can not do.

Say something from the heart.

Proxy IP this thing with good is really save, but don't buy cheap chicken service provider. Before the cheap buy 9.9 monthly, the result is that half of the IP are black, delayed the project progress not to mention, but also almost by the party fined money. Now stable with ipipgo enterprise version, although the price is expensive, but wins in the worry, there are problems at any time to find people to solve.

One final note for newbies:Agents are not a panaceaThe request frequency control, request head camouflage these means. Like eating hot pot, only spicy pot base can not, dipping dishes have to keep up, the meal to eat comfortably.
