Iterate through request headers

[mfallavol]

Can someone give me an example as to how to iterate through the headers in a request? I want to gather some information in the .upgrade handler.

I am very proficient with C but not so with the more complicated aspects of C++. I see that there is a HeaderIterator structure defined in HttpParser.h but I'm just not sure how to use it.

I can probably write you something up tomorrow.

It looks like the forEach functionality only exists in the node.js version. The C/C++ version doesn't define the forEach method.

HttpRequest implements an iterator, so you can just do for (auto header : req)

Thanks for the quick reply Alex but it doesn't compile. I get:
error: 'begin' was not declared in this scope

I thought perhaps it should be
for (auto header : req->headers)
But the compiler complains that headers is private.

for (auto header : *req) maybe

That did it, thank you very much.
