Synology QuickConnect Proxy

Although free proxies are popular, they are far from being flawless in their work. Many of their IP addresses are blacklisted by popular resources, and the data transfer speed and stability are very unreliable. When choosing a proxy, keep in mind that the new version of IPv6 is not supported by most websites. Note also that proxies are divided into private and public, statistical and dynamic, and support different network protocols.

It depends on the purpose for which you plan to work with proxies at all. Personally, one is enough for myself. But if you plan to do massive parsing, it may not be enough to have 100 pieces.

A proxy server passes all traffic through itself, acting as an intermediary between the user and the remote server. It is most often used to conceal the real IP, to conditionally change the user's location, or to analyze traffic (for example, when testing web applications).

Check the proxy settings: If you are using a proxy on your device or within an application, examine the proxy settings to see if the IP address (or hostname) of the proxy server is mentioned.

Observe the proxy URL: The proxy URL can sometimes indicate the IP address of the proxy server. For example, an HTTP proxy URL usually starts with "http://" or "https://" followed by the proxy server's IP address or hostname, while a SOCKS proxy URL typically starts with "socks://" followed by the proxy server's IP address or hostname.

Consult the proxy provider: If you are unsure about the IP address of the proxy server you are using, you can always consult the proxy provider or the documentation that came with the proxy server. They should be able to provide you with the necessary information about the proxy server's IP address.

Use online tools or software: There are various online tools and software applications that can help you identify the IP address of a proxy. By connecting to the proxy server and analyzing the traffic, these tools can often determine the IP address of the proxy server.

To obtain an OAuth2 access token for an unknown service, you will need to follow these general steps. Keep in mind that the exact process may vary depending on the service provider and their OAuth2 implementation.

1. Identify the service provider: Determine the service provider you want to access using OAuth2. This could be a third-party application or API.

2. Check the service provider's documentation: Visit the service provider's official documentation or developer portal to find information about their OAuth2 implementation, including the authorization endpoint, token endpoint, and any required scopes or parameters.

3. Register your application: In most cases, you will need to register your application with the service provider to obtain a client ID and client secret. This is usually done through a dedicated developer portal or console. During registration, you may need to provide information about your application, such as its name, description, and redirect URIs.

4. Obtain authorization code: Direct the user to the service provider's authorization endpoint with the necessary parameters, such as the client ID, client secret, and the desired scopes. The user will be prompted to log in and grant your application access to the requested permissions. Upon successful authentication, the service provider will redirect the user to your application's redirect URI with an authorization code in the URL.

5. Exchange authorization code for an access token: Use your application's backend server to make a POST request to the service provider's token endpoint with the following parameters: client ID, client secret, authorization code, redirect URI, and (optionally) a grant type (usually "authorization_code"). The service provider will respond with an access token, which can be used to authenticate requests to their API on behalf of the user.

6. Store and use the access token: Save the access token securely in your application or cache, and use it in the Authorization header of your API requests to the service provider. Access tokens typically have an expiration time, so you may need to periodically refresh them using a refresh token or by repeating the authorization flow.
