Encapsulate HTTP Fundamental Capabilities into a Utility

[lispking]

Overview

Currently, when dealing with various HTTP requests, there is a lack of unified encapsulation of fundamental capabilities. As a result, different HTTP services have to repeatedly handle basic functions such as the retry mechanism and rate-limiting. In order to improve development efficiency and reduce code redundancy, we plan to encapsulate these HTTP fundamental capabilities into a utility.

Specific Requirements

1. Encapsulation of Fundamental Capabilities
   • Retry Mechanism: When an HTTP request fails, it should be able to retry according to preset rules, such as setting the number of retries, the retry interval time, etc.
   • Rate-limiting Function: Implement rate-limiting for HTTP requests to prevent the server from rejecting requests or system resource exhaustion due to overly frequent requests. Parameters like the maximum number of requests per second can be set.
   • Other Fundamental Functions: Such as request timeout setting, error handling, etc.
2. Provide General Interfaces
   The encapsulated utility should provide simple and easy-to-use general interfaces, which are convenient for other developers to use in different projects. The interfaces should have good documentation for easy understanding and invocation.
3. Scalability
   The utility should have a certain degree of scalability, allowing developers to customize and expand it according to specific requirements. For example, it should support custom retry strategies, rate-limiting algorithms, etc.

Implementation Ideas

1. First, implement the basic retry mechanism and rate-limiting function, and conduct unit tests to ensure the correctness of the functions.
2. Design and implement general interfaces to expose the encapsulated fundamental capabilities to the outside.
3. Provide detailed documentation, including the usage of the interfaces, the meaning of parameters, sample code, etc.

Dependencies

The implementation of this utility may rely on existing HTTP client libraries, such as reqwest, etc.

• reqwest: provides a convenient, higher-level HTTP Client
• governor: a rate-limiting library

Related Tasks

1. Implement the HTTP retry mechanism.
2. Implement the HTTP rate-limiting function.
3. Design and implement general interfaces.
4. Write detailed documentation.
5. Conduct integration tests to ensure the stability and compatibility of the utility in different scenarios.

Subsequent Impact

Once this utility is encapsulated, for subsequent development work involving HTTP services, such as the implementation of gharchive #7 , secondary processing can be carried out based on this utility, avoiding the repeated development of fundamental capabilities and improving development efficiency.
