Configure JMeter proxy to record actions in the local web application

I am new to JMeter and I want to download a test test application for a local web application with a JMeter proxy.

I first used the instruction http://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.pdf , and everything was in order.

Than:

• I launched a web application let's say http://localhost:8080/my-application
• Configuring JMeter Web Proxy on port 8081
• Added default HTTP request for thread group
• Addea a recording controller
• Called curl -X GET http://localhost:8081/my-application/index.html

I get:

• The request is recorded, but with incorrect parameters, for example. https instead of http
• I do not get the requested page with curl, but an exception: org.apache.http.client.ClientProtocolException: URI does not specify a valid host name: https:///my-application/index.html/my-application/index.html
• , Http Request Default, , innored? HTTP Proxy Server .

? - ? JMeter Proxy ?
