undefined reference to `HttpClient::finishRequest()`

[weberc2]

v2.2.0 - It looks like finishRequest() is declared in the header file but not implemented anywhere. Seems related to #24, but that ticket contained no information for working around this issue.

I'm seeing this as well.

EDIT: corrected my initial statement, which involved a protected method. Fixed to use the public one.

I spent some time in the source code figuring this out. It looks like finishHeaders() is what we should use, or endRequest() endRequest() is the right method. The maintainer should really remove the bogus finishRequest() from the header.

If you need to send request headers, do something like this sequence:

// Tell the library you'll be sending some extra headers so it
// doesn't end the request headers automatically.
http_client.beginRequest();

// Send the GET request.
http_client.get(SERVER, PORT, PATH);

// Add headers.
http_client.sendHeader("foo", "bar");

// Finish the request.
http_client.endRequest();

The last commit was 9 years ago, so I will assume that the author is no longer maintaining this library.
