Could a simpler method for reading the Request/ response body be implemented in .NET

Hi @,

If you just want to store this information somewhere else, you can try use the CopyToAsync() method to asynchronously reads the bytes from the current stream and writes them to another stream, this will return a task when it done. You could use it to write a middleware to handle the request/respond body in asp.net core. Just refer to Stream.CopyToAsync Method (System.IO) | Microsoft Learn for more information.

Another way is caching the data after you got the data. Here is the code snippet for you:

var sr = new StreamReader(HttpContext.Request.Body);              
string requestInfo = await sr.ReadToEndAsync();              
if (string.IsNullOrEmpty(_cache.Get<string>("RequestInfo")))             
{                 
	// use IMemoryCache to write request info into cache.                 
	_cache.Set<string>("RequestInfo", requestInfo);             
}

Based on this, you can also add some request body parameters, such as timestamp, as judgment conditions for your logic code.

You could also read the ‘Photo service scenario’ in Caching in .NET - .NET | Microsoft Learn. It provides more detail about how to implement it.
