Proxy for LoadRunner

In the browser settings, select "Open Browser Settings" and then, finding the "Advanced" button, go to the "System" section. Click on the button "Open proxy server settings for computer" and in the section "Manual proxy settings" move the slider to the position "On". Now enter in the appropriate fields the IP address, proxy, port and click "Save".

To set up a proxy on your computer, you need to go through a simple procedure. If we're talking about Windows 10, you'll first need to open the "Settings" application and the "Network and Internet" section. Here, after opening the "Proxy Server" tab, find the column "Manual proxy server setup" just to the right and move the switch to the "On" position. Enter the IP address and the proxy port in the specified fields and click "Save".

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.

The ModuleNotFoundError: No module named 'selenium' error indicates that Python cannot find the Selenium module in your current environment. To fix this issue, you can follow these steps

1. Install Selenium

Open your terminal or command prompt.

Run the following command to install Selenium using pip:

pip install selenium

Make sure you are running this command in the same environment where your Python script is intended to run.

2. Check Python Version

Ensure that you are using the correct Python version and that you are installing Selenium for that specific version. You can check your Python version by running:

python --version

Ensure that the pip command corresponds to the version of Python you are using.

3. Check Virtual Environment (if applicable)

If you are using a virtual environment, make sure it is activated. Install Selenium after activating the virtual environment.

# Activate the virtual environment
source venv/bin/activate  # Linux/Mac
.\venv\Scripts\activate   # Windows

# Install Selenium
pip install selenium

4. Check Project Interpreter in IDE

If you are using an Integrated Development Environment (IDE) such as PyCharm, make sure that the project interpreter is correctly set to the Python environment where Selenium is installed. You can check and set the interpreter in the IDE settings.

5. Recreate Virtual Environment (if applicable)

If you are still facing issues, you may consider recreating the virtual environment. Deactivate the current virtual environment, delete the existing one, and create a new virtual environment. Activate the new virtual environment and install Selenium.

6. Check System PATH

Ensure that the directory containing the Python executable and scripts is included in your system's PATH environment variable. This allows the Python interpreter to be found when executing commands.

7. Check for Typos

Double-check your code for any typos or mistakes in the import statement. Ensure that you are using the correct casing and spelling for the module name.

After following these steps, try running your Python script again. The ModuleNotFoundError should be resolved if Selenium is successfully installed in your Python environment. If the issue persists, there might be an issue with your Python environment or project configuration that requires further investigation.

Connect your computer to a functioning router, then open any browser, go to the settings and enable manual configuration. Specify the IP, gateway with DNSI and subnet mask in the appropriate fields. In the "Home network" tab, under "Computers", go to "IPMP Proxy" and turn off this function. Under "System", click on the gear symbol, and under "Components", specify the Proxy UDP HTTP utility and click "Refresh".
