: Правильное использование константы HeaderNames.AcceptCharsetЗамена строкового литерала на константу из

улучшает поддерживаемость кода и уменьшает вероятность опечаток.

: Улучшение читаемости кода путем выделения логики чтения тела запросаВыделение логики чтения тела запроса в отдельный метод улучшает структуру кода. Убедитесь, что вызов
EnableBuffering()
по-прежнему эффективен для последующего чтения тела.✅ Verification successful
Let me check the implementation of GetBodyString method to ensure EnableBuffering is properly utilized.
Let me try a different approach to find the GetBodyString implementation.
Подтверждение корректности работы с буферизацией запроса
Проверка показала, что реализация метода
GetBodyString
корректно использует буферизацию:
- Вызов
EnableBuffering()
происходит до чтения тела запроса- После чтения тела позиция потока сбрасывается в начало (
request.Body.Position = 0
)- В комментарии явно указано сохранение доступности тела для следующего middleware
Рефакторинг выполнен правильно и сохраняет необходимую функциональность буферизации.

Ошибка в логике обработки отмены запроса
Текущая реализация продолжает обработку запроса при его отмене (IsCancellationRequested == true
). Это противоречит ожидаемому поведению - при отмене запроса обработка должна быть прекращена.
Предлагаемое исправление:
// Skip if request has been aborted.
if (context.RequestAborted.IsCancellationRequested)
{
- await _next.Invoke(context);
+ return;
}

🛠️ Refactor suggestion
Рекомендации по оптимизации чтения тела запроса
Текущая реализация работоспособна, но есть возможности для улучшения:
- Размер буфера 1024 байта может быть недостаточным для больших запросов
- Отсутствует защита от чрезмерного потребления памяти при очень больших запросах
Предлагаемые улучшения:
private static async Task<string> GetBodyString(HttpRequest request)
{
+ const int maxRequestSize = 10 * 1024 * 1024; // 10 MB
+ if (request.ContentLength > maxRequestSize)
+ {
+ throw new InvalidOperationException("Размер запроса превышает допустимый предел");
+ }
+
// Leave the body open so the next middleware can read it.
using var reader = new System.IO.StreamReader(
request.Body,
Encoding.UTF8,
false,
- 1024,
+ 4096, // Увеличенный размер буфера
true);
string bodyString = await reader.ReadToEndAsync();
request.Body.Position = 0;
return bodyString;
}
