<h1> Best Practices for Proxies IP: Helping You Easily Bypass Anti-Crawlers</h1>
<h3>Why choose to use Proxies for web crawling?</h3>
<p>In the era of big data, web crawling has become a core means to obtain market intelligence, monitor competitors, and conduct data analysis. However, with the increasing maturity of anti-crawler technology, large-scale data crawling with just an ordinary IP will often trigger the protection mechanism of the website, resulting in IP blocking, restricted access, and even legal disputes. The use of <strong>Proxies<em>*</strong>IP</em>* not only bypasses these restrictions, but also effectively protects privacy, and is a key tool to ensure that the crawling task goes smoothly.</p>

<strong>Why use Proxies<em>*</strong>IP<strong></em><em>?</strong>
1. <strong>Through</em><em></strong>IP<strong></em>*blocking and anti-crawling mechanism</strong>: Proxies IP can make the server think that it is not the same client making the request, thus avoiding the triggering of anti-crawler measures. Websites usually monitor how often IPs are accessed, and if the same IP sends a large number of requests in a short period of time, it may be blocked. Using Proxies allows each request to come from a different IP, thus effectively circumventing this blocking.
2. <strong>Protect Privacy</strong>: When performing data crawling, using Proxies IP can hide your real IP address from tracing and legal prosecution. This not only enhances the security of the operation, but also ensures the privacy of the data collection.</p>
<p>Categorization of Proxies: Which one best suits your needs?</p>
<p>The choice of Proxies IP is crucial to the effectiveness of crawling. Based on the degree of Anonymous Proxies, Proxy IPs can be categorized into the following types, each of which has its own specific application scenarios, advantages and disadvantages.</p>
<ol>
<li><strong>Transparent Proxies</strong>: Transparent Proxies do not hide the user's real IP address, so the other server will be able to recognize that you are using a Proxies and will know your real IP. this type of Proxies is usually not suitable for crawling tasks that require anonymity.</li>
<li><strong>Anonymous<em>*</strong>P<strong></em>*roxies</strong>: Anonymous Proxies hide the user's real IP address, but the server can still detect that you are using a proxy. Proxies of this type are suitable for operations that don't require complete anonymity, but still expose the fact that a proxy is being used to some extent.</li>
<li><strong>Highly Anonymous Proxies</strong>: Highly Anonymous Proxies completely hide the user's real IP and the server cannot detect that you are using a proxy. As a result, the server assumes that you are a normal user and is completely unaware that you are using a Proxies. This type of Proxies are ideal for web crawling to maximize privacy and avoid blocking.</li>
</ol>
<p><strong>In terms of crawling needs, highly Proxies are undoubtedly the most effective choice</strong> to efficiently accomplish data crawling tasks without revealing any identifying information.</p>
<h3>Best Practices for Using Proxies IPs for Web Crawling</h3>
<p>In practice, using Proxies IPs is more than simply adding them to your code. To maximize the use of Proxies, you also need to understand how to configure and manage Proxy IPs to avoid triggering a website's anti-crawler mechanism.</p>
<p><strong>1.<em>*</strong>Build a Proxies<strong></em><em>IP</em><em></strong>Pool</em>*
When using Proxies IPs, it is recommended to build a Proxies pool and randomly select Proxies IPs for requests. This way can further decentralize access requests and avoid being blocked for frequently using the same IP. The following is a simple code example showing how to build and use a Proxies pool:
```python
import requests
import random</p>
<h1>Proxies Pool List</h1>
<p>proxies = [
{'http':'222.138.76.6:9002'},
{'http':'221.178.232.130:8080'}
]</p>
<h1>Randomly select a Proxies IP</h1>
<p>proxy = random.choice(proxies) </p>
<h1>Using Proxies to Send Requests</h1>
<p>response = requests.get(url='http://httpbin.org/ip', proxies=proxy)
print(response.content.decode())
```
<strong>2.Regular update of Proxies IPs</strong>
Over time, some Proxies IPs may become invalid or blocked by target websites. Therefore, it is crucial to regularly check the availability of Proxies IPs and update the proxy pool. This can be achieved by automating scripts that periodically fetch new IPs from Proxies vendors and clean up unavailable old IPs.</p>
<h3>How to configure and use Proxies IP?</h3>
<p>The use of Proxies IP is not limited to code configuration, but can also be applied through system settings. The following are a few common Proxies configuration methods:
<strong>1.System Proxies Configuration</strong>
On Windows or macOS systems, you can manually configure Proxy IP through the network settings to specify that all network traffic goes through the Proxy Service:
* <strong>Windows configuration path</strong>: Network and Internet → Proxies → Manually Set Proxies → Edit → Enter IP and port number → Save
* <strong>macOS configuration path</strong>: System Preferences → Network → Advanced → Proxies → Enter IP and port number → Apply
This configuration is suitable for quickly enabling Proxies in scenarios that do not involve programming.</p>
<p><strong>2.Using Proxies in Code</strong>
It is easy to use Proxies IP for network requests in Python's urllib or requests library. The following is an example of configuring Proxies using the requests library:</p>
<p>```python
import requests</p>
<h1>Define the request headers (User-Agent simulates a browser to avoid being blocked)</h1>
<p>headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36'
}</p>
<h1>Define the proxy server (proxy server address and port number)</h1>
<p>proxy = {'http': 'http://proxy<em>server</em>address:port_number'}</p>
<h1>Send a GET request using the proxy and custom headers</h1>
<p>response = requests.get(url='http://httpbin.org/ip', headers=headers, proxies=proxy)</p>
<h1>Decode the response content and print it (shows the IP address as seen by the target server)</h1>
<p>print(response.content.decode())
<code>``
**Explanation:**
1.</code>headers<code>: This section defines the request headers, specifically setting the</code>User-Agent<code>to emulate a browser. This is usually used to avoid the server blocking requests from non-browser clients.
2.</code>proxy<code>: The configuration of the Proxy Service is specified here. The key is the protocol type (in this case</code>http<code>) and the value is the URL of the Proxy Service, which includes the address (</code>proxy<em>server</em>address<code>) and port number (</code>port_number<code>) of the Proxy Service.
3.</code>requests.get()<code>: This function sends an HTTP GET request to the specified URL (in this case,</code>http://httpbin.org/ip)<code>. The request uses a customized request header and is routed through the defined Proxy Service.
4.</code>print(response.content.decode())<code>: This line decodes the response content from bytes to a string and prints it. Typically, the response will contain the IP address that the destination server sees, which should be the address of the Proxy Service if set up correctly.
For example, my server address is</code>222.138.76.6<code>; port number is</code>1000<code>
then:</code>proxy = {'http': 'http://222.138.76.6:1000'}`</p>
<h3><strong>Detailed guide to configuring<em>*</strong>P<strong></em>*roxies for computers</strong></h3>
<ol>
<li>Proxies Configuration for Computer Systems</li>
</ol>
<p>In Windows or macOS system, you can manually configure the Proxy IP so that all network traffic is transmitted through the specified Proxy Service. Below are the specific configuration steps:
* <strong>Network and<em>*</strong>Internet<strong></em>*Settings</strong>:
* Open the system's network settings.
* Go to the “Network and Internet” option.
* Find and click Proxies.
* Select “Set Proxies Manually” and click “Edit”.
* Enable the “Use Proxy Service” option.
* Enter the IP address and port number of the Proxy Service.
* When finished, click “Save” to apply the settings.</p>
<p>If you need to disable the Proxies in the future, just follow the same path back and turn off the “Use Proxy Service” switch to save the settings.</p>
<ol>
<li><p>Configuring Proxies in Code
When writing code for web requests, configuring Proxies can help you achieve anonymous access, bypass geo-restrictions or anti-crawler mechanisms. The following is sample code for Proxies IP configuration in Python using the <code>urllib</code> and <code>requests</code> libraries:</p></li>
<li><p><strong>Proxies IP configurationusing</strong><code>urllib</code>:
```arduino
import urllib.request</p>
<h1>Set up the proxy handler with the proxy IP and port</h1></li>
</ol>
<p>handler = urllib.request.ProxyHandler({'http': 'http://222.138.76.6:9002'})
opener = urllib.request.build_opener(handler)</p>
<h1>Send the request using the opener object</h1>
<p>response = opener.open("http://www.baidu.com/")
print(response.read().decode())
<code>
In the above code, the ProxyHandler sets the Proxies IP address and port and the opener object is used to send requests through the proxy.
**Proxies IP is configuredusingthe requests library**:
</code>arduino
import requests # Import the requests library</p>
<h1>Set up the request headers to simulate a browser visit</h1>
<p>headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36'
}</p>
<h1>Configure the proxy IP address</h1>
<p>proxy = {
'http': 'http://222.138.76.6:9002'
}</p>
<h1>Send a GET request using the proxy</h1>
<p>response = requests.get(url='http://httpbin.org/ip', headers=headers, proxies=proxy)
print(response.content.decode()) # Print the returned IP address to verify proxy success
<code>
In this example, the proxies parameter is used to specify the proxy IP through which the requests.get() method sends the request, returning the IP address seen by the target website.
**Using multiple Proxies IPs**:
If you have multiple Proxies IPs, you can build a Proxies pool that randomly selects a Proxies IP for each request to avoid being blocked for using the same IP too often. Here is a code example:
</code>arduino
import requests
import random</p>
<h1>Set up request headers</h1>
<p>headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36'
}</p>
<h1>Build a proxy pool with multiple proxy IPs</h1>
<p>proxies = [
{'http': 'http://222.138.76.6:9002'},
{'http': 'http://221.178.232.130:8080'}
]</p>
<h1>Randomly select a proxy IP from the pool</h1>
<p>proxy = random.choice(proxies)</p>
<h1>Send a request using the randomly selected proxy IP</h1>
<p>response = requests.get(url='http://httpbin.org/ip', headers=headers, proxies=proxy)
print(response.content.decode())
```
Whether you are using a single Proxies IP or multiple Proxies IPs, the Request Library supports flexible proxy configurations that can be adapted to your needs.</p>
