redirect.go (2)
185-186: Ensure proper processing of flash messages.The new method
processFlashMessagesis correctly invoked after setting the status and before returning in theTomethod. This ensures that the flash messages are processed and set as cookies appropriately before the redirection response is sent.
243-244: Review ofparseAndClearFlashMessagesandprocessFlashMessages.
parseAndClearFlashMessages:
- This method correctly parses the cookie value for flash messages and clears the flash cookie after parsing. It ensures that flash messages are only available for the current request cycle, enhancing security by preventing stale flash message retrieval.
- The use of
findNextNonEscapedCharsetPositionfor parsing is efficient and handles potential character escaping within the cookie values.
processFlashMessages:
- Efficiently combines flash messages and old input data into a single cookie.
- The use of
bytebufferpoolfor string manipulation is a good practice to avoid unnecessary memory allocations.- Correctly clears the
messagesandoldInputafter processing to prevent data leakage on subsequent requests.- The use of
SessionOnlycookie attribute is a good security practice as it ensures that the cookie is not persisted across sessions.Overall, these methods are well-implemented with attention to performance, security, and correctness.
Also applies to: 262-296
router.go (1)
228-228: Updated method call inrequestHandler.The replacement of
setFlashwithparseAndClearFlashMessagesis correctly implemented. This change is consistent with the renaming inredirect.goand ensures that the updated method is called to clear flash messages appropriately during request processing.redirect_test.go (3)
37-53: Test coverage for redirection with flash messages.The new test
Test_Redirect_To_WithFlashMessagescorrectly checks the functionality of setting flash messages during redirection and ensures that the messages are correctly set in the response cookies. The test also validates the clearing of flash messages, which is crucial for security and correctness.
170-191: Test coverage forBackredirection with flash messages.The test
Test_Redirect_Back_WithFlashMessageseffectively validates the behavior of theBackmethod when flash messages are involved. It checks both the setting and clearing of flash messages, ensuring that the functionality aligns with the expected behavior after the recent changes.
Line range hint
264-277: Validation ofparseAndClearFlashMessagesfunctionality.The test
Test_Redirect_parseAndClearFlashMessagesis crucial as it directly tests the new method introduced inredirect.go. It ensures that the method correctly parses and clears the flash messages and old input data from the cookies, verifying both the retrieval of messages and inputs and their removal after processing.
