Where Should "defer req.Body.Close()" Be Placed in a Go HTTP Handler?

Optimizing Request Handling: Where Should "defer req.Body.Close()" Reside?

In web server environments, it's common practice to handle requests using net/http handlers. One question that arises is where to place the statement "defer req.Body.Close()".

Evaluating Placement Options

Should this statement be placed at the end of the function? Does it matter where it's positioned?

The Answer: No Need to Close

According to the official http.Request documentation, request bodies do not need to be closed in the handler. The server automatically takes care of closing them.

<br>// The Server will close the request body. The ServeHTTP<br>// Handler does not need to.<br>

This design choice eliminates the need for explicit closing and simplifies the handling of requests.

Therefore, it doesn't matter where you place "defer req.Body.Close()" in your function. You can choose to omit it altogether since the server handles body closure internally.
