Solicitudes POST

Envía solicitudes POST a través de Web Unblocker para enviar datos a sitios objetivo. Consulta cómo formatear y enviar datos POST con ejemplos de código.

Web Unblocker no solo admite el envío de solicitudes GET, sino que también le permite POSTear a un endpoint web de su elección. Puede enviar datos a un sitio web destino, haciendo que devuelva un resultado diferente.

Ejemplos de código

curl -k -v -x https://unblock.oxylabs.io:60000 \
-U 'USERNAME:PASSWORD' \
'https://ip.oxylabs.io/location' \
-d 'Your POST JSON: data'

# Web Unblocker no solo admite el envío de solicitudes GET, sino que también le permite POSTear a un endpoint web de su elección. Esto significa que puede enviar datos a un sitio web destino, que a su vez puede hacer que el sitio devuelva un resultado diferente.
