我们使用同步的 [**Realtime**](/products/cn/web-scraper-api/integration-methods/realtime.md) 集成方法作为示例。如果您想使用 [**Proxy Endpoint**](/products/cn/web-scraper-api/integration-methods/proxy-endpoint.md) 或异步 [**Push-Pull**](/products/cn/web-scraper-api/integration-methods/push-pull.md) 集成，请参阅 [**集成方法**](/products/cn/web-scraper-api/integration-methods.md) 部分。 ## 请求参数值 ### 通用
参数说明默认值
source设置爬虫。universal
url指向任何页面的直接 URL（链接）。-
callback_url您的回调端点 URL。 更多信息.-
\- 必填参数 ### 附加 以下是我们 [**功能**](/products/cn/web-scraper-api/features.md).
参数说明默认值
geo_location将代理的地理位置设置为以检索数据。查找支持的位置 这里.-
render设置为 html. 更多信息. 注意：如果你观察到成功率较低或返回空内容，请尝试添加此参数。-
browser_instructions定义你自己的浏览器指令，这些指令会在渲染 JavaScript 时执行。 更多信息.-
parse设置为 true，只要提交的 URL 页面类型存在专用解析器即可。false
parsing_instructions定义你自己的解析和数据转换逻辑，它将在 HTML 抓取结果上执行。了解更多： 解析指令示例.-
context:
headers		传入你自己的 headers。了解更多 这里.-
context:
Cookie		传入你自己的 Cookie。了解更多 这里.-
context:
session_id		如果你想使用同一个代理发起多次请求，可以使用此参数。只需将你的会话设置为任意字符串，我们就会为这个 ID 分配一个代理，并最多保留 10 分钟。之后，如果你用相同的会话 ID 发起另一请求，将为该会话 ID 分配一个新的代理。-
context:
http_method		将其设置为 post 如果你想发起一个 POST 通过 电商爬虫 API 请求你的目标 URL。了解更多 这里.get
user_agent_type设备类型和浏览器。完整列表可在 这里.desktop
context:
内容		Base64 编码 POST 请求正文。仅在以下情况下有用： http_method 设置为 post.-
content_encoding如果你正在下载图片，请添加此参数。了解更多 这里.base64
context:
follow_redirects		设置为 true 以启用爬虫跟随重定向。默认情况下，重定向最多跟随 10 个链接，并将整个链视为一个爬取任务。true
context:
successful_status_codes		定义一个自定义 HTTP 响应代码（或其中几个），对于这些代码，我们应将抓取视为成功，并将内容返回给你。如果你希望我们返回 503 错误页面，或在其他一些非标准情况下，这可能会很有用。-
**所有参数** 在此示例中，包含了所有可用参数（尽管并非总是必需，或在同一请求中兼容），以便让你了解如何格式化请求。 {% code fullWidth="false" %} ```json { "source": "universal", "url": "https://example.com", "user_agent_type": "desktop", "geo_location": "United States", "parse": true, "context": [ { "key": "headers", "value": { "Content-Type": "application/octet-stream", "Custom-Header-Name": "custom header content" } }, { "key": "Cookie", "value": [ { "key": "NID", "value": "1234567890" }, { "key": "1P JAR", "value": "0987654321" }] }, { "key": "follow_redirects", "value": true }, { "key": "http_method", "value": "get" }, { "key": "content", "value": "YmFzZTY0RW5jb2RlZFBPU1RCb2R5" }, { "key": "successful_status_codes", "value": [808, 909] }] } ``` {% endcode %} --- # Agent Instructions This documentation is published with GitBook.
