Can't get the 407 authentication pop-up? Teach you to use proxy IP to bypass the pit.
Have you ever encountered a web page suddenly popping up a 407 authentication box? Just like driving by the traffic police stopped to check the driver's license, do not fill in the right account password can not pass. This situation is particularly common in crawling data, batch operation, today we break open how to use a proxy IP to completely solve the problem.
Let's figure out where the 407 error came from.
Simply put, the server wants to verify the identity, but the current IP does not have a pass. It is common in three situations:
1. Enterprise-level fire interdiction(e.g. some government websites)
2. Double authentication is enabled on the target site
3. The proxy server itself requests authentication(Many free agents do this)
| Type of error | typical scenario | prescription |
|---|---|---|
| Client authentication failure | Wrong account password | Check proxy credentials |
| IP is blacked out by the target site | Frequent Visits Trigger Risk Control | Replacement of premium proxy IP |
Practical four steps to crack the certification
Step 1: Check proxy authorization information
In the ipipgo backend, find "My Keys" and put a file like thisuser-123:pass456The string is copied in its entirety into the authentication parameter of the code. Note that the colon must be an English symbol; many people fall for this detail.
Step 2: Enable the automatic retry mechanism
In the request header, add aProxy-Authorization: Basicparameter with ipipgo's dynamic key feature. We have tested that the authentication failure rate can be reduced from 30% to below 2% after this configuration.
Step 3: Switch IP Geolocation
Some regions are inherently prone to IP blocking. In ipipgo console select "intelligent switching" mode, the system will automatically match the highest pass rate of the server room node. Last week, a cross-border e-commerce customer used this method to increase the order capture success rate from 47% to 89%.
Step 4: The Ultimate Nuclear Weapon - Customized Protocol Headers
Put an artifact in the code: Q: I reported 407 even though I filled in the right password? Q: What should I do if I suddenly have a massive certification failure in the early morning? Q: How many spare IPs do I need to prepare? Our self-developedDynamic tunneling technologyCan automatically bypass 407 authentication: Don't panic when you run into 407, follow the above four steps to configure, and then with ipipgo's intelligent proxy service, basically can be fixed. If you really can't get it, our technical customer service is online 24 hours a day, send over the screenshot of the error, and we will give you a customized solution in minutes.
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36'}
Together with ipipgo's residential proxy, it can simulate real user behavior. Remember to update the UA regularly, don't use a fixed string copied from the internet.Frequently Asked Questions First Aid Kit
A: 80% is the problem of encoding format, use Base64 conversion tool to check. Or directly use the SDK provided by ipipgo to automatically handle encoding conversion.
A: Immediately log into the background of ipipgo to open the "emergency channel", will be temporarily assigned to the enterprise-level dedicated IP line. last year during the double eleven, a customer rely on this feature to keep the ten million orders.
A: It is recommended that the business volume of 20% as a buffer pool. For example, 10,000 requests per day, buy 1200 ipipgo high stash IP, so that even if there is an unexpected situation to carry.Why do you recommend ipipgo?
1. Automatically attach the latest key to each request
2. Intelligent identification of target site authentication rules
3. Automatic switching of alternate protocols for failed requests
Just recently upgraded to v3.2, which adds theAuthentication failure self-healingfunction, the system will automatically fix the 90% authentication problem within 3 seconds.
