自定义状态代码

默认情况下，我们假设请求成功，只要它返回2xx或4xx状态代码。然而，有时网站在返回所需内容的同时会出现非标准的HTTPS状态代码。如果您的一个目标出现这种情况，您可以指出哪些状态代码对您来说是可以接受的并且有价值的。添加X-Oxylabs-Status-Code标头到所有适用于您的HTTP响应代码。

2xx和4xx仍将被自动标记为成功。

网页解锁器只计算成功提取数据的流量。失败的抓取尝试将不计算在您所使用的流量中。上行和下行的流量都计入其中。

代码示例

curl -k -v -x ngrp.oxylabs.io:60000 \
-U user:pass1 "https://ip.oxylabs.io" \
-H "X-Oxylabs-Status-Code: 500,501,502,503"
