How to scrape Amazon product prices using residential proxy integrated with JAVA
by louise

In today's Internet era, data scraping has become an important means of obtaining information. As one of the world's largest online retailers, Amazon's product price information is of great value to many businesses and individuals.

However, due to the existence of various anti-crawler mechanisms, it is not easy to directly capture Amazon product prices. In order to solve this problem, we can use Residential Proxy to simulate the online behavior of ordinary users. 

The following will introduce how to use residential proxy integrated with JAVA to crawl Amazon product prices.

1. Choose the right residential agency service provider

When choosing the right residential agency service provider, consider the following aspects:

Stability: A stable proxy server can ensure the reliability of network connections and avoid problems such as disconnections and lags. Before choosing a service provider, you can evaluate its service level by testing its speed and quality.

Privacy protection capabilities: When using proxy services, you need to pay attention to protecting personal privacy to avoid leakage or abuse of personal information. You need to check the privacy protection policy to understand how the service provider protects users' private information and whether it can provide more secure proxy services.

Reputation and Reviews: User reviews are an important way to understand the quality of your residential agent’s service. You can check the reviews of other users to understand the reputation and service quality of the service provider, so as to make a more informed choice.

Professionalism: Regular service providers usually have more professional technical teams and advanced service equipment, and can provide better services. Choosing a regular service provider can ensure that the residential agency services it provides are more stable and reliable.

Price: The prices of different service providers may vary, and you need to choose according to your own needs and budget. However, don’t just use price as your only criterion and ignore other factors.

Service scope and areas of expertise: If you need to crawl web page data in a specific region, you need to determine the target location. Not every agent can meet your location needs. If you need to crawl web page data in a specific field, such as real estate, finance, etc., you need to know whether the agent has professional knowledge in the relevant field.

Technical support and after-sales service: In the process of using agency services, you may encounter various problems and you need to seek technical support from the service provider. Therefore, it is very important to choose a service provider that provides good technical support and after-sales service.

2. Configure proxy settings in JAVA program

In the JAVA program, you need to configure the IP address and port number of the proxy server. You can use JAVA's System.setProperty() method to set the proxy:

System.setProperty("http.proxyHost", "your_proxy_ip");

System.setProperty("http.proxyPort", "your_proxy_port");

Please replace your_proxy_ip and your_proxy_port with your actual proxy server IP address and port number.

3. Write a data capture program

Next, you need to write a JAVA program to capture Amazon product prices. You can use JAVA's network programming library, such as HttpClient or OkHttp, to send HTTP requests and get responses. Here is a simple example program:

import java.net.HttpURLConnection;

import java.net.URL;

import java.io.BufferedReader;

import java.io.InputStreamReader;


public class AmazonPriceScraper {

     public static void main(String[] args) throws Exception {

         //Set the proxy server IP and port number

         System.setProperty("http.proxyHost", "your_proxy_ip");

         System.setProperty("http.proxyPort", "your_proxy_port");


         // Build product URL

         String amazonUrl = "https://www.amazon.com/dp/product_ID";

         URL url = new URL(amazonUrl);

         HttpURLConnection conn = (HttpURLConnection) url.openConnection();




         //Read and print product price information

         BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));

         String inputLine;

         StringBuffer response = new StringBuffer();

         while ((inputLine = in.readLine()) != null) {





         String priceInfo = extractPriceInfo(response.toString()); // Implement price information extraction logic

         System.out.println("Amazon product price: " + priceInfo);



Please note that the above code is only an example and does not implement the specific logic of price information extraction. Corresponding parsing logic needs to be written according to the HTML structure of the Amazon website. 

In addition, logic such as status codes and exception handling for processing HTTP responses also need to be considered.

4. Processing the captured data and precautions

After successfully capturing Amazon product prices, the data needs to be processed and analyzed. Various data processing and analysis tools can be used, such as Java's string processing functions, regular expressions, etc., to extract price information.

When processing and analyzing data, attention needs to be paid to data accuracy and completeness, while data privacy and compliance issues also need to be considered. In addition, you must abide by laws, regulations and website regulations and avoid infringing on the rights and interests of others.

When using a residential proxy, you should pay attention to choosing a legal and reliable proxy service provider, and use proxy resources rationally to avoid abuse that results in restricted access to the IP address.
