Solicitações POST

Envie solicitações POST por meio do Web Unblocker para enviar dados a sites-alvo. Veja como formatar e enviar dados POST com exemplos de código.

Web Unblocker não apenas oferece suporte ao envio de requisições GET, mas também permite fazer POST para um endpoint web de sua escolha. Você pode enviar dados para um site de destino, fazendo com que ele retorne um resultado diferente.

Exemplos 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 não apenas oferece suporte ao envio de requisições GET, mas também permite fazer POST para um endpoint web de sua escolha. Isso significa que você pode enviar dados para um site de destino, que então pode fazer o site retornar um resultado diferente.
import requests

# Use suas credenciais do Web Unblocker aqui.
USERNAME, PASSWORD = 'YOUR_USERNAME', 'YOUR_PASSWORD'

# Defina o dicionário de proxy.
proxies = {
  'http': f'http://{USERNAME}:{PASSWORD}@unblock.oxylabs.io:60000',

# Imprima a página de resultado em stdout
