Today I'm going to share with you how to set up an HTTP proxy server on your Android phone. As an Android user, I know the importance of network security and privacy protection, so I often use proxy servers to protect my private information. By setting up an HTTP proxy server, we can realize the interception and modification of cell phone network requests, thus realizing some interesting functions. Let me introduce it in detail below!

1. What is an HTTP proxy server?

First of all, let's understand what HTTP proxy server is. Simply put, an HTTP proxy server acts as a "middleman" between the client and the origin server. It receives network requests from the client and forwards them to the origin server, and it also receives responses from the origin server and forwards them to the client. Through this middleman role, we can intercept, modify or even tamper with network requests and responses to achieve some personalized network functions.

2. Setting up an HTTP proxy server on an Android phone

Next, I will show you how to set up HTTP proxy server on Android phone. In Android system, we can set up the HTTP proxy server by setting the system network configuration. The specific steps are as follows:

First of all, open the settings menu of your phone, find the "Wireless and Network" option, and click to enter the "Network Settings" interface.

Next, find the "Mobile Network" or "Wi-Fi" option and click to enter the corresponding network settings interface. Here, we can see the "Proxy" option, click to enter the settings interface.

In the Proxy Settings interface, we can choose "Manual" mode, and then enter the address and port number of the proxy server. Usually, we can find the address and port number of the proxy server in the website or app of the proxy provider.

3. Code examples

In Android, we can also set up an HTTP proxy server by way of code. Below is a simple code example that demonstrates how to set up an HTTP proxy server in an Android application:

public class MainActivity extends AppCompatActivity {
protected void onCreate(Bundle savedInstanceState) {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.
super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);

// Set the HTTP proxy server
System.setProperty("http.proxyHost", "your_proxy_host");
System.setProperty("http.proxyPort", "your_proxy_port");; // Set the HTTP proxy server.

// Initiate a network request
try {
URL url = new URL("http://www.example.com");
HttpURLConnection urlConnection = (HttpURLConnection)url.openConnection();
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
// Read the network response
// ...
} catch (IOException e) {
e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); // Read the network response.
}
}
}

With the above code example, we can see that you can specify the address and port number of the HTTP proxy server by setting `System.setProperty`, and then just initiate the network request.

summarize

Through the above introduction, I believe you have understood the way to set up HTTP proxy server on Android phone, either through the system settings interface or through the code, you can easily realize the interception and modification of network requests. Of course, when using HTTP proxy servers, we should also pay attention to the principles of network security and legal use, and do not abuse proxy servers to carry out illegal activities. I hope we can all surf the Internet safely and healthily and enjoy the fun of the network world!
