II. How Will Smart Proxy Help in Scraping AliExpress?
AliExpress, as one of the largest e-commerce platforms globally, offers valuable data for businesses and researchers in a massive scale. However, scraping data from AliExpress comes with its own set of challenges. These challenges include IP bans, CAPTCHAs, and the need to bypass bot detection mechanisms. Smart Proxy by Crawlbase is the solution that will empower you to overcome these obstacles and extract data from AliExpress effectively.
Bypassing IP Blocks and Restrictions
AliExpress employs IP blocking as a common measure to prevent excessive scraping activities. By constantly rotating your IP address, Smart Proxy helps you bypass these restrictions effortlessly. This means you can scrape without the fear of getting your IP address blocked, ensuring uninterrupted data collection.
Outsmarting CAPTCHAs
CAPTCHAs are another hurdle you'll encounter while scraping AliExpress. These security tests are designed to differentiate humans from bots. Smart Proxy's rotating IP addresses feature comes to the rescue here. When CAPTCHAs appear, Smart Proxy intelligently switches to a new IP address, ensuring that your scraping process remains smooth and continuous. You won't be slowed down by these security checks.
Evading Bot Detection
AliExpress, like many online platforms, uses sophisticated bot detection mechanisms to identify and block automated scraping activities. Smart Proxy's automated IP rotation significantly reduces the risk of being detected as a bot. By continuously changing IPs, Smart Proxy keeps your scraping activities discreet, allowing you to scrape data anonymously.
High-Speed Data Extraction
Efficiency is crucial in web scraping, and Smart Proxy excels in this aspect. It ensures that your requests are processed with minimal delays, enabling you to extract data from AliExpress rapidly. Moreover, with its multi-threaded operation, Smart Proxy can process multiple requests concurrently, further enhancing the speed and efficiency of your web scraping tasks.

Smart Proxy not only enhances efficiency but also prioritizes your anonymity. By routing your requests through multiple proxy servers, it keeps your online identity discreet, allowing you to perform web scraping with the highest level of privacy and security.
Now that we have discussed the importance of Smart Proxy in scraping AliExpress, are you prepared to unlock its potential for your scraping needs? In the upcoming section of our blog, we'll take you through the step-by-step process of writing code in Python and seamlessly integrating Smart Proxy to craft a highly efficient web scraper customized for AliExpress.
III. Basic Smart Proxy Usage with Curl Command
Before we set up our Python environment, let’s try to test Smart Proxy and fetch data from the AliExpress web page using a simple curl command. Your first step will be to create an account with Crawlbase and go to your Smart Proxy dashboard to obtain the Proxy Authentication token.
Once you have the token, open your command prompt or terminal, copy the command line below, replace USER_TOKEN with the token you’ve obtained earlier, and hit enter to execute the code.
curl -x "http://USER_TOKEN@smartproxy.crawlbase.com:8012" -k "https://aliexpress.com/w/wholesale-macbook-pro.html"
This curl command will make an HTTP request to your target URL through Crawlbase's Smart Proxy. The proxy is set to run on smartproxy.crawlbase.com at port 8012 and the -k option tells curl to ignore SSL certificate verification. It is used when connecting to a server over HTTPS and you don't want to verify the authenticity of the server's certificate.
In the context of Crawlbase's Smart Proxy, it's crucial to disable SSL verification. Failure to do so may hinder the interaction between the Smart Proxy and your application.
Upon successful execution, you should receive an HTML response from AliExpress similar to the one shown in this screenshot:
IV: Adding Parameters to Smart Proxy Requests
Since Smart Proxy forwards your requests to the Crawling API, it also benefits from most of the capabilities of the Crawling API. You can fine-tune your requests by sending specific instructions, known as parameters, through a special header called CrawlbaseAPI-Parameters.
This lets you tell Smart Proxy exactly how you want it to handle your request. You can customize it to fit your needs perfectly.
In this case, we will be using a parameter called scraper=aliexpress-serp. This tells Smart Proxy to extract the website's response and organize it in a way that's easy to understand. It's like asking Smart Proxy to turn messy website data into neat and organized information.
curl -H "CrawlbaseAPI-Parameters: scraper=aliexpress-serp" -x "http://USER_TOKEN@smartproxy.crawlbase.com:8012" -k "https://aliexpress.com/w/wholesale-macbook-pro.html"
V. Creating AliExpress web scraper using Python
Step 1. Configuring your Python Project
Now that we’ve discussed the very basic details of how Smart Proxy operates. We’re ready to set up our Python environment.
Start by making sure you have Python installed on your machine. If this is your first time using Python, we recommend our Python beginner guide and follow the step-by-step procedure on how to properly set up Python on your system.
Step 2. Setting Up Project Directory
Once you have configured Python on your machine, we now need to set up a new project. Open your console or terminal and execute the following command.
mkdir crawlbase
-
mkdir: This is a command that stands for "make directory." It's used to create a new directory. -
crawlbase: This is the name of the directory you want to create. In this case, it's named "crawlbase," but you could replace it with any other name you prefer.
Next, execute the command below.
cd folder-name && touch crawlbase.py
-
cd folder-name: This command stands for "change directory." It is used to navigate to a specific folder. Replace "folder-name" with the name of the folder you want to enter. -
&&: This is a logical operator that means "and." In the context of this command, it ensures that the second part of the command (touch crawlbase.py) is executed only if the first part (cd folder-name) is successful. -
touch crawlbase.py: Thetouchcommand is used to create an empty file. In this case, it creates a file named "crawlbase.py" in the directory specified by the precedingcdcommand.
So, when you run this line of code, it does two things:
- It changes the current directory to the one specified by "folder-name."
- It creates a new, empty Python file named "crawlbase.py" in that directory.
Step 3. Installation of Dependencies
To retrieve data from the AliExpress webpage and save it to a JSON file, we require two essential packages.
Requests: This package simplifies the process of sending HTTP/1.1 requests. You don't have to manually add query strings to your URLs or encode your PUT & POST data. You can just use the json method for simplicity.
JSON: Python has native support for JSON. It comes with a built-in package called json for encoding and decoding JSON data, eliminating the need to install an additional package.
To get these packages, use the following command:
pip install requests
This command ensure you have the necessary tools to fetch data from AliExpress and handle JSON operations in your Python script.
Step 4. Utilizing Smart Proxy with Python
We've reached the point where we can begin crafting our main Python code and integrate the Smart Proxy call.
In the previous section, we created a file called crawlbase.py. Get to this file, copy the code below and run it to retrieve the desired data.
import requests
# replace with your Crawlbase user_token.
username = 'USER_TOKEN'
password = '' # password is empty, its not used for authentication.
proxy_auth = f'{username}:{password}'
url = 'https://nl.aliexpress.com/w/wholesale-macbook-pro.html'
proxy_url = f"http://{proxy_auth}@smartproxy.crawlbase.com:8012"
proxies = {"http": proxy_url, "https": proxy_url}
response = requests.get(url=url, proxies=proxies, verify=False)
print('Response Body: ', response.content)
Importing the requests Library:
This line imports the requests library, which simplifies the process of making HTTP requests in Python.
Setting up Proxy Authentication:
Replace 'USER_TOKEN' with your actual Crawlbase user token. This token is used for authentication when making requests through the Smart Proxy. The proxy_auth variable is then formatted to include the username and an empty password, following the basic authentication format.
Defining the URL and Proxy URL:
-
url: This is the target URL you want to scrape. In this case, it's an AliExpress webpage related to MacBook Pro wholesale. -
proxy_url: This is the URL of the Smart Proxy server, including the authentication details. The URL format ishttp://username:password@proxy_host:proxy_port.
Setting up Proxies:
The proxies dictionary is created to specify the proxy settings. Both "http" and "https" are set to use the same proxy URL.
Making the Request:
-
requests.get: This function initiates an HTTP GET request to the specified URL. -
proxies: The proxies parameter is set to use the configured proxy settings. -
verify=False: This parameter is set toFalseto ignore SSL certificate verification. In a production environment, it's crucial to handle SSL verification properly.
Printing the Response Body:
This line prints the content of the response, which includes the HTML or data retrieved from the specified URL.
Step 5. Execute the Python Code
crawlbase.py
A successful response of the code will fetch the complete HTML source code of the AliExpress URL and display it on your console. This data is not yet useful in most cases as it will be difficult to dissect. In order to get more sensible and easy-to-read data, we must parse this response and turn it into structured data which we can then store in a database for easy retrieval and analysis.
Step 6. Parsing the Data using the AliExpress scraper
The Smart Proxy’s capability to automatically parse AliExpress data will be utilized in this step. To do this, we simply need to pass the scraper=aliexpress-serp with CrawlbaseAPI-parameters as a header in our code. Edit your crawlbase.py file and paste the code below.
import requests
import json
# replace with your Crawlbase user_token.
username = 'USER_TOKEN'
password = '' # password is empty, its not used for authentication.
proxy_auth = f'{username}:{password}'
url = 'https://nl.aliexpress.com/w/wholesale-macbook-pro.html'
proxy_url = f"http://{proxy_auth}@smartproxy.crawlbase.com:8012"
proxies = {"http": proxy_url, "https": proxy_url}
headers = {
"CrawlbaseAPI-Parameters": "scraper=aliexpress-serp"
}
response = requests.get(url=url, proxies=proxies,
headers=headers, verify=False)
data = json.loads(response.text)
print('Response Scraped Body: ', json.dumps(data, indent=4))
Once you execute this code, the response will be in JSON format as shown below:

Step 7. Saving Parsed Data to a JSON file
Of course, we will not let the data go to waste. In this step, we will add a few lines to our code so we can store the scraped data safely for later use. Go back to your crawlbase.py file again and paste the code below.
import requests
import json
# replace with your user_token which you get from your dashboard.
username = 'USER_TOKEN'
password = '' # password is empty, its not used for authentication.
proxy_auth = f'{username}:{password}'
url = 'https://nl.aliexpress.com/w/wholesale-macbook-pro.html'
proxy_url = f"http://{proxy_auth}@smartproxy.crawlbase.com:8012"
proxies = {"http": proxy_url, "https": proxy_url}
headers = {
"CrawlbaseAPI-Parameters": "scraper=aliexpress-serp"
}
response = requests.get(url=url, proxies=proxies,
headers=headers, verify=False)
data = json.loads(response.text)
with open('scraped_data.json', 'w') as json_file:
json.dump(data, json_file)
print('Response Scraped Body: ', json.dumps(data, indent=4))
Processing and Saving the Response as JSON:
-
json.loads(response.text): This converts the JSON-formatted text of the response into a Python dictionary. -
with open('scraped_data.json', 'w') as json_file: Opens a file named 'scraped_data.json' in write mode. -
json.dump(data, json_file): Writes the Python dictionary (converted JSON data) to the file.
VI. Strategies for Scaling Up your Python Project
Scaling this web scraping project involves managing a large number of requests efficiently and ensuring that your project remains reliable and compliant with the website's terms of service. Here are some strategies to consider:
Use Asynchronous Requests: Instead of making requests one by one, consider using asynchronous programming with libraries like asyncio and aiohttp. Asynchronous requests allow you to send multiple requests concurrently, significantly improving the speed of your scraping process.
Parallel Processing: This strategy can be applied to handle multiple URLs concurrently, speeding up the overall data retrieval process. Python provides various mechanisms for parallel processing, and one common approach is to use the concurrent.futures module.
Use a Proxy Pool: When dealing with a large number of requests, consider using a pool of proxies to avoid IP bans and distribute requests. Crawlbase’s Smart Proxy solves this problem for you as it intelligently rotates through different proxies for each request to prevent detection.
Distributed Scraping: If the volume of URLs is extremely high, you might want to consider a distributed architecture. Break down the scraping task into smaller chunks and distribute the workload across multiple machines or processes.
Handle Errors Gracefully: Implement error handling to manage network errors, timeouts, and other unexpected issues. This ensures that your scraping process can recover from failures without crashing.
Optimize Code Efficiency: Review your code for any inefficiencies that may impact performance. Optimize loops, minimize unnecessary computations, and ensure that your code is as efficient as possible.
Database Optimization: Use a reliable database (e.g., PostgreSQL, MySQL) for storing scraped data. Implement proper indexing to speed up retrieval operations, or batch insert data into the database to reduce overhead.
