Streaming via 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.

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.

The error message "cannot create temp dir for user data dir" typically occurs when Selenium is unable to create a temporary directory for its user data. This issue can be caused by several factors, such as insufficient permissions or a full disk.

Here are some steps you can take to resolve this issue:

Check available disk space:

Ensure that your system has enough free disk space to create a temporary directory. If your disk is almost full, consider clearing some space or moving files to another storage location.

Check permissions:

Make sure that your user account has the necessary permissions to create and modify files and directories in the specified location. You can try changing the permissions of the directory or creating a new directory with the appropriate permissions.

Specify a custom user data directory:

You can specify a custom user data directory for Selenium by using the --user-data-dir option in the ChromeOptions class. This allows you to choose a location with enough free space and the appropriate permissions.

Here's an example of how to set a custom user data directory in Python:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument("--user-data-dir=/path/to/custom/user/data/dir")

driver = webdriver.Chrome(options=chrome_options)
driver.get('your_url')

# Rest of your code

driver.quit()

Replace /path/to/custom/user/data/dir with the path to the directory you want to use as the user data directory.

Check for antivirus or security software interference:

Sometimes, antivirus or security software can interfere with the creation of temporary directories. Try temporarily disabling your antivirus or security software to see if it resolves the issue. If it does, you may need to add an exception for Selenium or change your antivirus settings.

Restart your system:

In some cases, simply restarting your system can resolve the issue. This can help free up disk space and resolve any temporary issues with permissions or disk access.

If you've tried all these steps and are still encountering the error, please provide more information about your system, including the operating system, disk space, and any relevant error messages or logs. This will help diagnose the issue further and find a suitable solution.

There are lots of ways to use them. For example, you can swap your real IP address location for an American one, thus getting the opportunity to watch Netflix at a bargain price. Or you can set up parsing traffic through a proxy to test the security of your web applications. Or you can create a proxy server on your local network that allows traffic through and blocks requests to certain sites.

Start the program and add a template. Click on it twice to open a window. Here you need to specify the path to the file with the proxy and save the settings. Enter the following format in the file: HTTPS - 195.3.218.232:8000 - if the proxy is bound to your IP, or login:[email protected]:8000 - if you use a proxy with username and password authentication. Under "Settings" click on "Default", or fill everything in manually, and then confirm the changes you made.
