Authenticate and request user timeline using Twitter API v1.1 OAuth

Introduction

Due to the recent deprecation of Twitter API v1, users must migrate to API v1.1. This guide demonstrates how to use the HttpWebRequest object to authenticate and request a user's timeline without relying on a third-party application.

Identity Verification

1. Generate OAuth keys and keys from https://www.php.cn/link/30fad467b7363d55fa24b3398fdef557.
2. Create the authorization header by combining the encoded key and secret key.
3. Submit a request to the OAuth URL with the authorization header and grant_type set to "client_credentials".
4. Deserialize the response to get token_type and access_token.

Timeline Request

1. Construct the timeline URL with the desired screen name.
2. Create a new authorization header using the token_type and access_token obtained from authentication.
3. Send a GET request to the timeline URL and include the authorization header.
4. Read the response and deserialize the JSON result, or just retrieve the JSON string.
