10 REST API BEST PRACTICES

发布时间：2023年12月17日

  1. Use descriptive and meaningful resource names-
    Instead of generic or ambiguous names, choose resource names that accurately represent the entities they represent.

  2. Use HTTP methods correctly-
    Use the appropriate HTTP methods (GET, POST, PUT, DELETE, PATCH, etc.) for different operations.

  3. Version your APIs-
    Use versioning to ensure backward compatibility and allow for future enhancements without breaking existing clients.

  4. Use HTTP status codes correctly-
    Return the appropriate HTTP status codes to indicate the success or failure of an API request.

  5. Pick your JSON field naming convention (and stick to it)-
    JSON standard doesn’t impose a field naming convention, but it’s a best practice to pick one and stick with it.

  6. Use consistent error messages-
    In most cases, HTTP status codes are not enough to explain what went wrong.
    To help your API consumers, include a structured JSON error message.
    The response should include the following information-

  • Error code: A machine-readable error code that identifies the specific error condition.
  • Error message: A human-readable message that provides a detailed explanation of the error.
  • Error context: Additional information related to the error, such as the request ID, the request parameters that caused the error, or the field(s) in the request that caused the error.
  • Error links: URLs to resources or documentation that provide additional information about the error and how it can be resolved.
  • Timestamp: The time when the error occurred.

  1. Use query parameters for filtering, sorting, and searching-
    Query parameters allow you to provide additional information in the URL of an HTTP request to control the response returned by the server.

  2. Implement authentication and authorization-
    Secure your APIs by implementing proper authentication and authorization mechanisms.

  • =>USE API KEYS, TOKENS, OR OAUTH 2.0 FOR AUTHENTICATION

  • =>APPLY ROLE-BASED ACCESS CONTROL (RBAC) FOR AUTHORIZATION

  1. Do not maintain state-

  • A REST API should not maintain a state on the server. That’s the responsibility of the client.

  • This is important because it allows for the API to be cacheable, scalable, and decoupled from the client.

  • For example, an e-commerce API might use cookies to maintain the state of a shopping cart. However, such an approach violates key the key principle of RESTful APIs — they need to be stateless.

  1. Document your APIs-
    Provide comprehensive documentation for your APIs, including endpoint details, request/response examples, and usage guidelines .
