How to implement context-related dialogue function in OpenAI's API?

Context dialogue in OpenAI API: Cleverly use Prompt to achieve continuous interaction

The simple Q&A features of the OpenAI API are easy to get started, but it takes some tricks to achieve more natural context-related conversations. The official documentation does not directly provide context or conversation_id parameters to maintain the context, so we need to manage the conversation history ourselves.

This article will guide you how to implement context-related dialogue functionality by cleverly building Prompt.

Key Strategy: Manage conversation history in the application and integrate it into Prompt

The specific steps are as follows:

  1. Conversation History: Your app needs to maintain a list that records questions and replies to the model each time the user enters.

  2. Build an effective Prompt: Every time a user asks, integrate conversation history into the new Prompt. This allows the model to understand the previous conversation and generates more coherent replies.

  3. Control Prompt length: The OpenAI API has restrictions on Prompt length. If the conversation history is too long, the following strategies need to be considered:

    • Truncate: Delete earlier conversation content.
    • Abstract: Use summary technology to condense conversation history into shorter text.
  4. Process and update history: After receiving a model reply, add it to the conversation history and display it to the user.

In this way, even without direct context parameters, the dialogue context can be effectively managed at the application level, achieving smooth and natural continuous dialogue. This is a flexible and efficient solution that allows your application to interact with the OpenAI API at a higher level.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
