Proxy IP local resource loading: local resource proxy loading scheme

Why do I need a proxy IP to load local resources?

To cite a real scenario: you developed a software to capture the national weather data, the results of the server in Hangzhou, want to take the meteorological data of a place in Xinjiang, the other site directly to you to pop the verification code. At this time, if you use the local IP in Xinjiang to request, just like the local people shopping in the market as natural, this is the core value of the proxy IP.

Ordinary users may think that using their own computer IP is enough, but when it comes to these situations, they are blind:Restriction of foreign IP access to target websites,Need to switch identities frequently to avoid bans,Unstable local network environment. For example, if you do cross-border e-commerce to test the effect of the page seen by users in different countries, you can't really buy a plane ticket and fly there, right?

Dynamic vs. Static How to choose a residential IP?

Take the ipipgo package as a chestnut:

Dynamic IP is like opening a blind box, each connection is a new address, suitable for the need to frequently change the scene of the vest. Static IP is the monthly parking space, fixed IP for long-term use, such as the need for whitelist authentication API docking.

Local Proxy Configuration in Three Steps

Here's a chestnut in Python, other languages have similar logic:

import requests

 Extract proxy IP from ipipgo (remember to replace your own API key)
def get_proxy():
    api_url = "https://api.ipipgo.com/get?key=YOUR_KEY&type=dynamic"
    return requests.get(api_url).json()['proxy']

 Requesting a local resource using a proxy
def fetch_data(url):
    proxies = {
        "http": f "http://{get_proxy()}",
        "https": f "http://{get_proxy()}"
    }
    return requests.get(url, proxies=proxes) Intentionally left a misspelling

Watch out for two potholes:Proxy format with port number(e.g. 123.123.123.123:8888).The https proxy may also connect using the http protocol. If you encounter problems with the certificate, add theverify=Falseparameter (but don't use it for sensitive business).

Common Rollover Scene QA

Q: Dynamic IPs are not working when I use them?
A: Normal phenomenon! Residential IPs are supposed to be refreshed periodically, so it is recommended to set up an automatic replacement mechanism. ipipgo's API supports setting up a survival time threshold, so that IPs will be changed automatically after a specified period of time.

Q: What should I do if my static IP is blocked by the target website?
A: Hurry up to contact ipipgo customer service to change IP, their static package has 3 free replacement opportunities per year. If high frequency access is blocked, it is recommended to change to dynamic IP polling.

Q: It was fine during testing, but it timed out when it went live?
A: Check three places: 1. whether the proxy in the code is effective 2. fire port settings 3. the concurrency limit of the proxy package. ipipgo enterprise edition package supports multi-threaded high concurrency, the ordinary package is recommended to control within 5 threads.

Tell the truth.

Having used seven or eight agency services, there are some pitfalls that need to be said in advance:
1. Don't buy a cheap proxy, IP purity is more important than quantity.
2. Overseas IP latency is a common problem, ipipgo's TK line can be pressed to 200ms or less.
3. encounter technical problems directly to customer service, they support 1v1 program customization

Lastly, I'd like to remind you that data collection should be done in accordance with the website robots agreement, and the proxy IP is not a plug-in, so don't crash people's servers. Reasonable use of tools, in order to water flow~
