How to output all of uWS request's headers?

I want something close enough to this example

  h.onConnection([&h](uWS::WebSocket<uWS::SERVER> ws, uWS::HttpRequest req) {
    // TODO: output request's path
    std::cout << "Request's path << req.getPath() << std::endl; // how to?
    std::cout << "Output all request's headers: ";
    std::for_each(req.headers.begin(), req.headers.end(). [] (std::string h) { std::cout << h << std::endl; });
    std::cout << "Connected!!!\n";
  });

i have installed all the dependeces,but when i run " cmake .. && make“ ,it failed show:

who can help me
thank you very much!

Hi @domluna @baumanab,
I notice that our project doesn't have license, that's a little unprofessional for a open source project, especially there has much extends adoption and development in an online education project. "No license terms" means users don't know it can be used freely. Another reference is Can I call my program "Open Source" even if I don't use an approved license?.

So here I suggest the project add license, recommend we choose one of the below license, firstly because they're all Permissive Licenses, but they have different redistribution disclaimer:

• MIT
• Apache-2.0
• BSD-3-Clause

Regards,
Brandon

To install OpenSSL, I tried

brew install openssl

And it returns

Warning: openssl is a keg-only and another version is linked to opt.
Use `brew install --force` if you want to install this version

Then I tried

brew install --force openssl

And it returns

Warning: openssl-1.0.2k already installed, it's just not linked.

Then I tried to link with force

brew link --force

Then it returns

Warning: Refusing to link: openssl
Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
  -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

And I don't know what to do next.

When I run "install-mac.sh", it failed.

Hello,

I'm having trouble getting the compiled version to work on my machine
Please see:
#3
https://discussions.udacity.com/t/project-build-for-windows-users/245846/11

Any suggestions or ideas? I'm just trying to get the base code provided to work.
