Proxy for Octave

All modern Smart TVs allow you to use proxies to connect to the Internet or local network (both on Android and Tizen OS). You have to go to the device settings, open "Network" tab (can be named as "Ethernet"), and then in "Advanced settings" to activate the proxy, if necessary - specify its settings.

To scrape JSON data using RxJava in a Java application, you can use the RxJava library along with an HTTP client library to make requests. Below is an example using RxJava2 and OkHttp to scrape JSON data from a URL asynchronously.

Add Dependencies

Add the following dependencies to your project:

    io.reactivex.rxjava2
    rxjava
    2.x.y 




    com.squareup.okhttp3
    okhttp
    4.x.y 

Write the Code:

import io.reactivex.Observable;
import io.reactivex.schedulers.Schedulers;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class JsonScrapingExample {

    public static void main(String[] args) {
        String url = "https://api.example.com/data"; // Replace with your JSON API URL

        // Create an Observable that emits a single item (the URL)
        Observable.just(url)
                .observeOn(Schedulers.io()) // Specify the IO thread for network operations
                .map(JsonScrapingExample::fetchJson)
                .subscribe(
                        jsonData -> {
                            // Process the JSON data (replace this with your scraping logic)
                            System.out.println("Scraped JSON data: " + jsonData);
                        },
                        Throwable::printStackTrace
                );
    }

    // Function to fetch JSON data using OkHttp
    private static String fetchJson(String url) throws Exception {
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder()
                .url(url)
                .build();

        try (Response response = client.newCall(request).execute()) {
            if (!response.isSuccessful()) {
                throw new Exception("Failed to fetch JSON. HTTP Code: " + response.code());
            }

            // Return the JSON data as a string
            return response.body().string();
        }
    }
}

2. • Replace the url variable with the actual URL of the JSON API you want to scrape.
   • The fetchJson function uses OkHttp to make an HTTP request and fetch the JSON data.

3. Run the Code:

   • Execute the Java code to fetch and process the JSON data asynchronously using RxJava.

This example uses RxJava's Observable to create an asynchronous stream of events. The observeOn(Schedulers.io()) part specifies that the network operation (fetchJson) should run on the IO thread to avoid blocking the main thread.

Make sure to handle exceptions appropriately and adjust the code based on the structure of the JSON API you are working with.

JSON scraping typically involves extracting data from a JSON response obtained from an API. When you mention doing JSON scraping sequentially, it could mean processing items in the JSON response one after another. Below is a simple example in Python that demonstrates sequential processing of JSON data:

import requests

def fetch_data(url):
    response = requests.get(url)
    return response.json()

def process_item(item):
    # Replace this with your actual processing logic
    print("Processing item:", item)

def scrape_sequentially(api_url):
    data = fetch_data(api_url)

    # Assuming the JSON response is a list of items
    if isinstance(data, list):
        for item in data:
            process_item(item)
    else:
        print("Invalid JSON format. Expected a list of items.")

# Replace 'https://example.com/api/data' with the actual API URL
api_url = 'https://example.com/api/data'
scrape_sequentially(api_url)

In this example:

1. The fetch_data function sends a GET request to the specified API URL and returns the JSON response.
2. The process_item function represents the logic you want to apply to each item in the JSON response.
3. The scrape_sequentially function fetches the JSON data, checks if it's a list, and then iterates through each item, applying the processing logic sequentially.

Make sure to replace the placeholder URL 'https://example.com/api/data' with the actual URL of the API you want to scrape.

A DNS server is a remote computer that receives a domain request from a user device. And it converts it into an IP address. Sometimes it is through the DNS-server that ISPs block sites. And DNS-proxy, respectively, allows you to bypass these restrictions completely.

Parsing is the collection of all information. Accordingly, parsing a site is copying all of its source code as presented. You can use it to edit the site further or to analyze it for security purposes.
