Proxy Endpoint

通过 Oxylabs 网页爬虫 API 的代理端点发送和接收数据。通过简单的基于 URL 的集成直接访问目标页面。

如果您曾经将常规代理用于数据抓取，那么集成 Proxy Endpoint 传输方式将非常简单。您只需将我们的入口节点用作代理，使用 Scraper API 凭据进行授权，并忽略证书。在 cURL，它是 -k 或 --insecure。您的数据将通过一个开放连接到达您处。

Proxy Endpoint 仅适用于基于 URL 的数据源，其中提供了完整的 URL。因此，它只接受少数额外的作业参数，这些参数 应作为头部发送.

该产品并不旨在直接与无头浏览器（例如 Chromium、PhantomJS、Splash 等）及其驱动程序（例如 Playwright、Selenium、Puppeteer 等）一起使用。

请参见下面的请求示例。

curl -k -x https://realtime.oxylabs.io:60000 \
-U 'USERNAME:PASSWORD' \
-H 'x-oxylabs-user-agent-type: desktop_chrome' \
-H 'x-oxylabs-geo-location: Germany' \
'https://www.example.com'

可接受的参数

在发出请求时，除了 URL 外，您还可以向我们发送一些在执行任务时使用的作业参数。作业参数应在您的请求头中发送 - 参见示例此处.

以下是您可以随 Proxy Endpoint 请求一起发送的作业参数列表：

参数

说明

x-oxylabs-user-agent-type

无法指定具体的 User-Agent 字符串，但您可以告诉我们希望使用哪种 user-agent 类型。受支持的 User-Agent 类型列表可在此处.

x-oxylabs-geo-location

在某些情况下，您可能需要指明结果应适配的地理位置。此参数对应于 geo_location 参数，其在源级文档中另行描述。可接受的值取决于您希望我们抓取的 URL。阅读更多此处.

x-oxylabs-render

JavaScript 执行。阅读更多此处.
