如何获得HTTP响应的大小？

Question

I want to determine the size of the response. it's easy way to get the contentsize by resp.ContentLength. But, Size is the combined size of the response headers (usually a few hundred bytes) plus the response body, as delivered by the server. how can I get the size of the response headers ? Or Is there anyway to get the size of the response directly?

Answer 1

You can implement an http.ResponseWriter that counts the bytes it writes. It should be pretty simple to create your own, or you can use an existing library like this one.
