Fbox Proxy

A proxy server is a kind of "mediator" between your equipment and a remote server (or the whole Internet). It can be used, for example, to swap your real IP address for another one, to bypass blocking. Proxies can also be actively used to intercept traffic (e.g. when testing created web applications).

VPN allows you to hide your real IP address, as well as further encrypt your traffic. VPN is also actively used for address spoofing. For example, the user is in the Russian Federation, but by connecting through a VPN server, the site "thinks" that the user is from the United States.

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.

A proxy address, also known as a proxy URL or proxy server address, is the address used to connect to a proxy server. It typically consists of the following components:

Protocol: The protocol used to connect to the proxy server, such as HTTP, HTTPS, or SOCKS.

Username and password (optional): Authentication credentials for accessing the proxy server, if required.

Proxy server IP address or hostname: The IP address or hostname of the proxy server.

Port number: The port number on which the proxy server is listening for connections.

A proxy address might look like this:

http://:@:/

Here, and represent the proxy server's authentication credentials, is the proxy server's IP address or hostname, and is the proxy server's port number.

The "Unexpected token while deserializing object" error usually occurs when the JSON you are trying to parse contains invalid syntax or unexpected characters. To fix this error, follow these steps:

1. Check the JSON structure: Ensure that the JSON string you are trying to parse is well-formed and follows the correct syntax. JSON should only contain valid characters, such as alphanumeric characters, whitespace, and a few special characters like quotes, brackets, and colons.

2. Remove or escape unexpected characters: If the JSON string contains unexpected characters, such as line breaks or comments, remove them or escape them using the appropriate escape sequences. For example, replace line breaks with \n and comments with //.

3. Validate the JSON string: Use a JSON validator tool, such as JSONLint, to check if the JSON string is valid and properly formatted. If there are any syntax errors, the validator will point them out, allowing you to fix them.

4. Use a JSON parser: If you are using a programming language like JavaScript, use a JSON parser to parse the JSON string. For example, in JavaScript, you can use the JSON.parse() method to parse the JSON string:

try {
  const jsonObject = JSON.parse(jsonString);
  // Work with the parsed object...
} catch (error) {
  console.error("Error parsing JSON:", error);
}

5. Handle exceptions: When using a JSON parser, make sure to handle exceptions that may occur if the JSON string is invalid. This will help you identify and fix any issues with the JSON string.

By following these steps, you should be able to fix the "Unexpected token while deserializing object" error and successfully parse the JSON string.
