error: called object 'socket' is not a function or function pointer

[inderjeetrao]

Getting Error:
CC build/oap-http/esp_request.o
sensor-esp32/components/oap-http/./esp_request.c: In function 'nossl_connect':
sensor-esp32/components/oap-http/./esp_request.c:128:14: error: called object 'socket' is not a function or function pointer
socket = socket(PF_INET, SOCK_STREAM, 0);

It seems due to change in ESP IDF.

According to the solution above changes will need to done in esp_request.c file.
