Ipfs Proxy

It is recommended to use third-party programs that allow redirecting all traffic through a proxy server. For example, ProxyDroid, EveryProxy. It is not possible to use proxies through the regular menu. Although in phones from some manufacturers such possibility has been added.

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).

The first thing you need to do to use a proxy in your browser is to make the necessary settings. In Google Chrome browser, go to "Network" and then find and click on "Change proxy settings". In the "Internet properties" window that opens, go to "Connection" and click on the "Network settings" button at the bottom. When a new window opens, check the "Use proxy server for local connections" box and the "Do not use proxy server for local addresses" box. Enter the proxy port and IP address in the corresponding fields, close the window and click "OK".

It depends on which browser you are using. In Opera, Chrome, Edge a proxy is configured at the level of the operating system itself. In Firefox in the settings there is a special item (in the "Privacy" section).
