# See Global Unlock Sample for sample code.

http = Chilkat::CkHttp.new()

http.put_AuthToken("ACCESS_TOKEN")

http.put_Accept("application/json")

resp = Chilkat::CkHttpResponse.new()
success = http.HttpNoBody("GET","https://www.googleapis.com/gmail/v1/users/userId/messages",resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

print "Response Status Code: " + resp.get_StatusCode().to_s() + "\n";

jsonResponse = Chilkat::CkJsonObject.new()
jsonResponse.Load(resp.bodyStr())
jsonResponse.put_EmitCompact(false)
print jsonResponse.emit() + "\n";

if (resp.get_StatusCode() != 200)
    print "Failed." + "\n";
