Debugging HTTP Requests in ASP.NET Core Across Environments

Debugging HTTP Requests in ASP.NET Core Across Environments

在 ASP.NET Core 中跨环境调试 HTTP 请求

When the same HTTP request works in dev but fails in production, debugging gets messy fast. Example: a request returns 200 in dev but 400 in prod because of a missing header or slightly different payload—and it’s not obvious why. 当同一个 HTTP 请求在开发环境中运行正常，但在生产环境中却失败时，调试过程会变得非常棘手。例如：一个请求在开发环境中返回 200，但在生产环境中却返回 400，原因可能是缺少某个标头或负载（payload）存在细微差异，且原因并不显而易见。

Most of the time, this means jumping between logs, Postman, and custom middleware, trying to spot the difference. To simplify this, I started working on a lightweight way to capture and inspect HTTP requests and responses directly inside the app (headers, body, timing). 大多数情况下，这意味着你必须在日志、Postman 和自定义中间件之间来回切换，试图找出差异。为了简化这一过程，我开始着手开发一种轻量级的方法，直接在应用程序内部捕获并检查 HTTP 请求和响应（包括标头、正文和耗时）。

The idea is simple: capture everything in one place and compare requests across environments to quickly see what changed. It’s still early stage, and I’m exploring better comparison and visualization. How do you debug these cases today? 这个想法很简单：将所有内容集中捕获，并对比不同环境下的请求，从而快速发现变化之处。目前该项目仍处于早期阶段，我正在探索更好的对比和可视化方案。你们平时是如何调试这类问题的呢？
