Push-Pull

了解 Oxylabs 网页爬虫 API 的 Push-Pull 集成方法。提交任务后，可在稍后使用 JSON 格式数据轮询结果端点。

Push-Pull 是我们推荐的集成方法，用于可靠地处理大量数据。

访问 Oxylabs 的 GitHub 仓库以获取完整的工作示例，演示 Python 中的 Push-Pull 集成.

Push-Pull 是一种异步集成方法。提交任务后，您将立即收到一个 JSON 响应，其中包含所有任务详情，包括任务参数、ID 以及用于结果下载和状态检查的 URL。任务处理完毕后，如果您提供了 JSON 有效载荷，我们会将其发送到您的服务器，前提是您提供了回调 URL。结果在完成后至少可以 检索 24 小时 以上。

通过 Push-Pull，您可以将结果直接上传到您的 云存储 （Google Cloud Storage、AWS S3、Alibaba Cloud OSS 或其他兼容 S3 的存储）。

如果您不想为接收回调通知设置服务，您也可以定期检索结果（轮询).

您还可以使用以下工具探索 Push-Pull 的工作方式： Postman.

单个任务

端点

此端点仅接受单个 query 或 URL 值分隔。

POST https://data.oxylabs.io/v1/queries

输入

请在 JSON 有效负载中提供任务参数，如下示例所示。Python 和 PHP 示例包含注释以便说明。

curl --user "user:pass1" \
'https://data.oxylabs.io/v1/queries' \

数据字典

有关任务输入参数的详细说明，请查阅下表或参考您感兴趣的爬虫的具体文档页面。

键

说明

类型

created_at

任务创建的日期时间。

字符串

client_id

与发起请求的客户端用户名关联的数值 ID。

字符串

client_notes

客户端在发送任务时提交的备注。

字符串

content_encoding

如果您要下载图像，请添加此参数。了解更多此处.

字符串

id

任务的唯一 ID。

字符串

statuses

抓取或解析任务的状态码。您可以在此处查看状态码描述此处.

整数

status

任务的状态。 pending 表示任务仍在处理中。 done 表示我们已完成任务。 faulted 表示我们在尝试完成任务时遇到错误并放弃了。

字符串

subdomain

网站的子域名。

字符串

updated_at

任务最后更新时间的日期时间。对于已完成的任务（status is done 或 faulted），此日期时间表示任务完成的时间。

字符串

链接

与所提供输入相关的链接列表。

JSON 数组

链接:rel

链接类型。 self URL 包含任务的元数据，而 results URL 包含任务结果。

字符串

链接:href

资源的 URL。

字符串

链接:方法

应使用的 HTTP 方法来与给定 URL 交互。

字符串

回调

回调是我们发送到您机器上的一个 POST 请求，用于通知数据提取任务已完成并提供用于下载抓取内容的 URL。这意味着您无需 手动检查任务状态 。一旦数据到达，我们会通知您，您只需 检索它.

检查任务状态

如果您在提交任务时提供了有效的回调 URL，我们将在任务完成时通过向指定的回调 URL 发送一个 JSON 有效载荷来通知您。该有效载荷将表明任务已完成并且其状态设置为 done.

但是，如果您提交任务时未使用 回调服务，您可以手动检查任务状态。从 href 字段中检索 URL，该字段位于提交任务后收到的响应消息的 rel:self 部分。用于检查任务状态的 URL 将类似于以下形式： http://data.oxylabs.io/v1/queries/12345678900987654321。查询此 URL 将返回任务信息，包括其当前 status.

状态值

参数

说明

pending

任务仍在处理中，尚未完成。

done

任务已完成。您可以通过查询响应中 href 字段下提供的 URL 来检索结果，位于 rel:results 部分，例如： http://data.oxylabs.io/v1/queries/12345678900987654321/results.

faulted

任务存在问题，未能完成。对于任何此类 faulted 任务您不会被收费。

检索任务内容

一旦任务准备好检索，您可以使用响应中在 rel:results 部分下提供的 URL。该 URL 看起来如下： http://data.oxylabs.io/v1/queries/7173957294344910849/results.

端点

您可以使用以下端点检索不同类型的结果：

GET https://data.oxylabs.io/v1/queries/{job_id}/results

GET https://data.oxylabs.io/v1/queries/{job_id}/results?type=raw

GET https://data.oxylabs.io/v1/queries/{job_id}/results?type=parsed

GET https://data.oxylabs.io/v1/queries/{job_id}/results?type=png

GET https://data.oxylabs.io/v1/queries/{job_id}/results?type=xhr

GET https://data.oxylabs.io/v1/queries/{job_id}/results?type=markdown

您也可以检索多种结果类型在单个响应中，例如：

GET https://data.oxylabs.io/v1/queries/{job_id}/results?type=parsed,raw

下面是一个示例响应，来自 /results 端点的代码示例：

{
  "results": [
    {
      "content": "<!doctype html><html>
        内容      
      </html>",
      "created_at": "2019-10-01 00:00:01",
      "updated_at": "2019-10-01 00:00:15",

      "status_code": 200
    }
  ]
}

结果可以通过设置回调服务来自动检索，而无需周期性地检查任务状态。为此，在提交任务时指定能够接受传入 HTTP(S) 请求的服务器的 URL。当我们的系统完成任务时，它将 POST 向提供的 URL 发送一个 JSON 有效载荷，回调服务将按 回调实现示例.

批量查询

Scraper APIs 支持在单个批量请求中提交最多 5,000 个 query 或 url 参数值。

Batch requests are currently not supported 用于 chatgpt 和 perplexity 来源。

端点

POST https://data.oxylabs.io/v1/queries/batch

系统将把每个 query 或 url 作为单独的任务处理。如果您提供回调 URL，则每个关键字都会收到单独的回调。否则，我们的初始响应将包含所有关键字的任务 id信息。例如，如果您发送了 50 个关键字，我们将返回 50 个唯一的任务 id。

重要： 使用 /batch 端点时，您只能提交 query或 url参数值的列表（取决于您使用的 source ）。所有其他参数应为单一值。

输入

您需要将查询参数作为 JSON 有效负载发布。以下是提交批量任务的方法：

curl --user "user:pass1" \
'https://data.oxylabs.io/v1/queries/batch' \
-H 'Content-Type: application/json' \
-d '@keywords.json'

import requests
import json

    payload = json.loads(f.read())

response = requests.request(
    'POST',
    'https://data.oxylabs.io/v1/queries/batch',
    auth=('user', 'pass1'),

import fetch from 'node-fetch';

您可能注意到上面的代码示例没有说明 JSON 有何格式，并且引用了一个预先制作的 JSON 文件。下面是 keywords.json 文件，包含多个 query 参数值：

{  
   "query":[  
      "adidas",
      "nike",
      "reebok"
   ],
   "source": "google_shopping_search",
   "domain": "com",
   "callback_url": "https://your.callback.url"
}

...下面是一个 keywords.json 批量输入文件，包含多个 URL：

{  
   "url":[  
      "https://example.com/url1.html",
      "https://example.com/url2.html",
      "https://example.com/url3.html"
   ],
   "source": "universal",
   "callback_url": "https://your.callback.url"
}

输出

该 API 将返回一个 JSON 对象，包含为每个创建的任务生成的任务信息。响应将类似于：

{
  "queries": [
    {
      "callback_url": "https://your.callback.url",
      {...}
      "created_at": "2019-10-01 00:00:01",
      "domain": "com",
      "id": "12345678900987654321",
      {...}
      "query": "adidas",
      "source": "google_shopping_search",
      {...}
          "rel": "results",
          "href": "http://data.oxylabs.io/v1/queries/12345678900987654321/results",
          "method": "GET"
        }
      ]
    },
    {
      "callback_url": "https://your.callback.url",
      {...}
      "created_at": "2019-10-01 00:00:01",

        }
      ]
    },
    {
      "callback_url": "https://your.callback.url",
      {...}

}

获取回调器 IP 地址列表

您可能想把向您发送回调消息的 IP 加入白名单，或为其他用途获取这些 IP 列表。您可以通过 GET访问此端点：

端点

GET https://data.oxylabs.io/v1/info/callbacker_ips

输入

下面的代码示例演示如何访问 /callbacker_ips 端点的代码示例：

curl --user "user:pass1" \
'https://data.oxylabs.io/v1/info/callbacker_ips'

import requests
from pprint import pprint

# 从回调 IP 端点获取响应。
response = requests.request(
    method='GET',
    url='https://data.oxylabs.io/v1/info/callbacker_ips',
    auth=('user', 'pass1'),
)

# 将美化的 JSON 响应打印到 stdout。
pprint(response.json())

<?php

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://data.oxylabs.io/v1/info/callbacker_ips");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_USERPWD, "user" . ":" . "pass1");

$result = curl_exec($ch);
echo $result;

if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close ($ch);
?>
