Crawler Software: Octopus/Scrapy Agent Integration Configuration Guide

Octopus crawler proxy IP setup hands-on tutorials

Many just use octopus white easy to get stuck in the proxy settings of this step, in fact, simpler than imagined. In theCollection rule settingInterface to findAdvanced OptionsIf you want to customize your proxy, paste the proxy address provided by ipipgo into the "Customize Proxy" field. Note that there is a pit here: you must choose the right protocol type, http and https do not confuse, fill in the wrong direct rest.

Focus on seeing if this is the right format:http://用户名:密码@GatewayAddress:PortThe username and password of ipipgo can be found in the background personal center, and it is recommended to directly copy and paste don't hand knock. Test time to open a simulated collection, in the log to see theSuccessful IP switchingThe wording is only really done.

Hands-on proxy configuration for the Scrapy framework

For Scrapy veterans, here's the recommended middleware way to hook up proxies. Add a custom middleware in middlewares.py, focusing on splicing the proxy address of ipipgo into request.meta. There is an evil situation to note: some sites will detect the proxy protocol header, this time in the DOWNLOADER_MIDDLEWARES to add a random switching logic.

As a chestnut, if you access ipipgo's dynamic residential IP pool, you can write it like this:

def process_request(self, request, spider).
    request.meta['proxy'] = f "http://{ipipgo_user}:{ipipgo_pass}@gateway.ipipgo.com:port"

What's the difference between a residential IP and a server room IP?

A lot of people get confused when it comes to picking an agent type, simply put:

Residential IP-From real home broadband, suitable for scenarios that need to simulate the operation of a real person, like certain e-commerce stations with strict wind control.
Server Room IP--of server hosting centers, suitable for crawling tasks that require stability and high speed.

ipipgo's residential IP pool covers 240+ regions around the world, especially the IP resources of those small and cold countries, which is the most suitable for cross-border e-commerce data collection. Their dynamic residential IP has a hidden benefit: each request automatically change IP, do not have to worry about the problem of IP blocking.

QA Frequently Asked Questions Demining

Q: The test agent always times out?
A: First check whether the network can ping through the gateway address, and then confirm that the account is not bound to the whitelist. ipipgo background has a real-time availability monitoring, you can see exactly which node out of the problem.

Q: Crawling and suddenly no data?
A: 80% is triggered by the anti-climbing mechanism. Suggestions: 1. reduce the frequency of requests 2. switch ipipgo's different country nodes 3. add a random User-Agent header

Q: What if I need a fixed IP?
A: ipipgo's static residential IP can be bound for 12-72 hours, which is suitable for collection tasks that require login status. But remember to release it in time after using it, you have to re-bill it if it exceeds the time.

Practical tips to prevent blocking

Having seen too many tragic cases of reptiles getting banned, here are a few life saving moves:

1. With ipipgoquantity-based billing modelIf the IP fails, it automatically switches without wasting money.
2. the survival time of each IP should not exceed 30 minutes
3. Use a mix of export IPs from different countries, don't catch a region grips
4. Remember to turn on ipipgo for important tasks.IP Health Detectionfunctionality

Lastly, don't be hard on the CAPTCHA. ipipgo's API supports automatic switching of validation nodes, and if you really can't get it right, you can go to their real-life validation service, which is much more worrying than the self-built coding platform. Remember, a good proxy service can double the efficiency of the crawler, don't be stingy on the tool.
