What to do if the crawler IP is restricted? Simple solution to crawler IP ban

With big data and information crawling becoming increasingly important, crawler technology has become a key means of obtaining Internet resources. However, frequent data crawling often causes crawler IPs to be restricted or banned by target websites, thus affecting the efficiency and integrity of data collection. This article will explore in depth the reasons and impacts of crawler IP restrictions and how to effectively solve this problem through strategies such as 98IP proxy IP, aiming to provide you with a set of practical solutions. I. Reasons and impacts of crawler IP restrictions 1.1 Cause analysis Access frequency is too high: a large number of requests are made to the same website in a short period of time, triggering the website's anti-crawler mechanism. Abnormal behavior pattern: such as unnatural access path, missing or forged request header information, etc., which can be easily identified as crawlers. Excessive resource consumption: long-term occupation of server resources affects normal user access to the website. 1.2 Impact Overview Data collection is blocked: after the IP is banned, the crawler cannot access the target website normally, and the data collection task is interrupted. Project progress delay: Frequent IP changes, adjustment of crawler strategies, and increased development and maintenance costs. Legal risks: Some websites have clear legal clauses for unauthorized crawling behaviors, which may involve legal risks. II. Introduction to 98IP proxy IP and its role in solving crawler IP bans 98IP proxy IP service provides dynamic and static proxy IP resources worldwide, with the characteristics of high anonymity, good stability, and fast response speed. By using proxy IP, crawlers can hide real IP addresses, simulate user access in different regions, and effectively avoid IP bans. 2.1 Advantages of 98IP proxy IP Wide coverage: IP resources in many countries and regions around the world to meet cross-regional data collection needs. High anonymity: Hide the real IP and reduce the risk of being identified as a crawler by the target website. High speed and stability: High-quality proxy servers ensure data transmission efficiency and stability. Flexible management: Provide API interface for easy integration and management of proxy IP pools. III. Practical methods to solve crawler IP blocking using 98IP proxy IP 3.1 Change IP regularly Set the crawler to change the proxy IP after each request or at a fixed time interval to avoid excessive access frequency of a single IP. import requests from some_proxy_pool_library import get_random_proxy # Suppose there is a library to get random proxies from 98 IPs def fetch_data(url): proxy = get_random_proxy() # Get a random proxy from the 98IP proxy pool proxies = { 'http': f'http://{proxy}', 'https': f'https://{proxy}' } try: response = requests.get(url, proxies=proxies) return response.text except Exception as e: print(f"Error fetching data: {e}") return None # usage example url = "http://example.com" data = fetch_data(url) print(data) 3.2 Randomize request headers Randomize the request header information such as User-Agent and Accept-Language for each request to simulate the access behavior of different users. import random from fake_useragent import UserAgent ua = UserAgent() headers = { 'User-Agent': random.choice(ua.browsers), 'Accept-Language': random.choice(['en-US,en;q=0.5', 'zh-CN,zh;q=0.9']), # Other necessary request header information } # Use these randomised request headers in your requests response = requests.get(url, headers=headers, proxies=proxies) 3.3 Control access frequency According to the load capacity and anti-crawler strategy of the target website, reasonably set the crawler access interval to avoid excessive pressure on the website. import time def crawl_with_delay(urls, delay=2): for url in urls: data = fetch_data(url) # Processing data time.sleep(delay) # Setting the access interval 3.4 Monitoring and adjustment strategy Continuously monitor the running status of the crawler and the changes in the anti-crawler strategy of the target website, and adjust the crawler strategy in time, such as increasing the proxy IP pool and optimizing the request parameters. IV. Summary and Outlook The restriction or blocking of crawler IP is an inevitable challenge in the process of data capture, but by reasonably using strategies such as 98IP proxy IP, the risk of IP blocking can be effectively reduced and the efficiency and quality of data collection can be improved. In the future, with the continuous development of big data and artificial intelligence technology, crawler technology will become more intelligent and automated, and the demand for proxy IP will beco

import requests
from some_proxy_pool_library import get_random_proxy  # Suppose there is a library to get random proxies from 98 IPs

def fetch_data(url):
    proxy = get_random_proxy()  # Get a random proxy from the 98IP proxy pool
    proxies = {
        'http': f'http://{proxy}',
        'https': f'https://{proxy}'
    }
    try:
        response = requests.get(url, proxies=proxies)
        return response.text
    except Exception as e:
        print(f"Error fetching data: {e}")
        return None

# usage example
url = "http://example.com"
data = fetch_data(url)
print(data)

import random
from fake_useragent import UserAgent

ua = UserAgent()
headers = {
    'User-Agent': random.choice(ua.browsers),
    'Accept-Language': random.choice(['en-US,en;q=0.5', 'zh-CN,zh;q=0.9']),
    # Other necessary request header information
}

# Use these randomised request headers in your requests
response = requests.get(url, headers=headers, proxies=proxies)

import time

def crawl_with_delay(urls, delay=2):
    for url in urls:
        data = fetch_data(url)
        # Processing data
        time.sleep(delay)  # Setting the access interval
