René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Strict Middleware Cannot Access Response Status Code","articleBody":"### Problem\n\nWhen using oapi-codegen generated strict middleware (`StrictMiddlewareFunc`), the response status code is not available during middleware execution.\n\n### Expected Behavior\n\n```go\nfunc Telemetry(f v1.StrictHandlerFunc, operationName string) v1.StrictHandlerFunc {\n    return func(ctx *gin.Context, request interface{}) (interface{}, error) {\n        result, err := f(ctx, request)\n        statusCode := ctx.Writer.Status() // Should return actual status (200, 404, etc.)\n        // ... telemetry collection\n        return result, err\n    }\n}\n```\n\n### Actual Behavior\n\n`ctx.Writer.Status()` always returns `0` because the response hasn't been written yet when strict middleware executes.\n\n### Root Cause\n\nThe oapi-codegen generated handlers write the response **after** all middleware has executed:\n\n```go\n// Generated handler pattern\nfor _, middleware := range sh.middlewares {\n    handler = middleware(handler, \"OperationName\") // Middleware runs here\n}\nresponse, err := handler(ctx, request)\n// Response writing happens AFTER middleware execution\nif err != nil {\n    ctx.Status(http.StatusInternalServerError) // Status set here\n}\n```\n\n### Request\n\nCould oapi-codegen provide a way for strict middleware to access the final response status code?","author":{"url":"https://github.com/humbledshuttler","@type":"Person","name":"humbledshuttler"},"datePublished":"2025-10-22T19:14:36Z","url":"https://github.com/oapi-codegen/oapi-codegen/issues/2111"}
