Light Proxy

To configure a proxy on your MikroTik router, you need the Winbox software. The following steps must be done in the application: Open the "IP"-"WebProxy" sections. Check the box next to "Enabled". Enter the parameters of the proxy-server.

After that you have to specify the data of the proxy in the browser to be used. As an example, let's take Google Chrome. What you need to do:

Open the browser.
Click on the icon "?" in the upper right corner.
Go to "Settings".
Select the "Advanced" option.
Click the "System" tab.
Click on "Open proxy settings for your computer".
Click on "Network settings".
Activate the "Use proxy server" option.
In the tab that opens, specify the IP address of the proxy server. You should enter it in the field of the protocol to which the proxy server belongs.
Click the "OK" button to save your settings.

In Android to disable the proxy, you need to go to "Settings", then - "Connection and sharing", then - to "VPN". And then just deactivate the item. Many phones also provide for automatic disabling of proxies and VPNs when the device is rebooted. That is, if the user is difficult to understand the settings of the gadget, then you can trivially restart it through a long press the lock button (forced reboot).

If you're working with Spring Boot in Java and need to parse JSON with multiple attachments, you might be dealing with a scenario involving HTTP requests with JSON payload and file attachments. In this case, you can use @RequestPart in your controller method to handle JSON and multipart requests.

Here's a basic example

Create a DTO (Data Transfer Object) class:

public class RequestDto {
    private String jsonData;
    private MultipartFile file1;
    private MultipartFile file2;

    // getters and setters
}

Create a controller with a method to handle the request:

import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestPart;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

@RestController
@RequestMapping("/api")
public class ApiController {

    @PostMapping("/processRequest")
    public ResponseEntity processRequest(@RequestPart("requestDto") RequestDto requestDto,
                                                @RequestPart("file1") MultipartFile file1,
                                                @RequestPart("file2") MultipartFile file2) {
        // Process JSON data in requestDto and handle file attachments
        // ...

        return ResponseEntity.ok("Request processed successfully");
    }
}

3. Send a multipart request with JSON and attachments:

Using tools like Postman or curl, you can send a multipart request. Here's an example using Postman:

• Set the request type to POST.
• Set the URL to http://localhost:8080/api/processRequest.
• Under the "Body" tab, select "form-data".
• Add three key-value pairs:
  • Key: requestDto, Value: {"jsonData": "your_json_data"}
  • Key: file1, Value: select a file
  • Key: file2, Value: select another file

Make sure you have the appropriate dependencies in your project for handling multipart requests. If you're using Maven, you can include the following dependency in your pom.xml:

    org.springframework.boot
    spring-boot-starter-web

Adjust the example based on your specific use case and the structure of your JSON data. The key point is to use @RequestPart to handle both JSON and file attachments in the same request.

If Selenium is not loading the specified browser profile, there are several possible reasons and solutions to investigate. Here are some steps you can take to troubleshoot and resolve the issue:

1. Check Profile Path:

   • Verify that the path to the specified browser profile is correct. Provide the absolute path to the profile directory when setting up the browser profile.

2. Ensure Browser Compatibility:

   • Make sure that the version of Selenium WebDriver you are using is compatible with the version of the browser. Compatibility issues can sometimes cause profile-related problems.

3. Use Browser-Specific Options:

   • Different browsers may have specific options for setting up a profile. For example, in Chrome, you can use user-data-dir to specify the user data directory (profile).

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--user-data-dir=/path/to/profile')

driver = webdriver.Chrome(options=chrome_options)

• Profile Settings Conflict:

  • Check if there are conflicting settings in the specified profile that might interfere with Selenium. Manually inspect the profile directory to ensure it is in a clean state.

• Clear Browser Cache and Cookies:

  • If you are using an existing profile, clearing the browser cache and cookies might help. Create a clean profile or clear the existing one before running your Selenium script.

• Profile Locking:

  • Ensure that the specified profile is not locked by another instance of the browser. Make sure that no other browser instances are using the same profile concurrently.

• Browser Version Mismatch:

  • If you have recently updated your browser, there might be compatibility issues with the existing profile. Create a new profile or update the existing one to match the browser version.

• Handle Security Restrictions:

  • Some browsers, especially when used in automated testing, may impose security restrictions on loading specific profiles. Review browser settings or consider adjusting security settings to allow profile loading.

• Check for Selenium Updates:

  • Ensure that you are using the latest version of the Selenium WebDriver library. Updates may include fixes for profile-related issues.

• Logging and Debugging:

  • Enable browser and WebDriver logs to capture any error messages or warnings related to the profile. This can provide insights into what might be going wrong.

• Use Browser-Specific Drivers:

  • If you are using a specific browser (e.g., Chrome, Firefox), make sure you are using the appropriate browser-specific WebDriver executable (ChromeDriver, GeckoDriver).

Working through a proxy involves routing your internet traffic through a proxy server, which acts as an intermediary between your device and the internet. This can be done for various reasons, such as improving security, privacy, or accessing content that may be restricted in your location. Here's how to work through a proxy:

Obtain a proxy server: First, you need to find a proxy server that meets your needs. You can find proxy servers through online directories or by asking for recommendations from friends, family, or online communities. Make sure to choose a reliable and trustworthy proxy server.

Configure your device or browser: Once you have a proxy server, you need to configure your device or browser to use the proxy. The process varies depending on the device and browser you're using.
