爬虫数据，如何获取您的电商API接口(爬虫和API概念，示例演示)

首先我们先来了解概念

网络爬虫（又称为网页蜘蛛，网络机器人，在FOAF社区中间，更经常的称为网页追逐者），是一种按照一定的规则，自动地抓取万维网信息的程序或者脚本。

 API简介
API：应用程序接口（API：Application Program Interface）是一组定义、程序及协议的集合，通过 API 接口实现计算机软件之间的相互通信。API 的一个主要功能是提供通用功能集。程序员通过调用 API 函数对应用程序进行开发，可以减轻编程任务。 API 同时也是一种中间件，为各种不同平台提供数据共享。

API接口很可能是远程的服务端API，其背后采用Java、PHP、C#、Pyhon、C/C++、Ruby、Scala等一种或多种后端语言开发搭建，提供了数据存储、通讯、各类服务等功能。一般是使用HTTP协议进行通讯，使用JSON格式序列化返回接口结果和数据。

version	String	否	API版本

 

&secret=<您自己的apiSecret>&num_iid=520813250866&is_promotion=1";
$curl = curl_init();
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,FALSE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,FALSE);
curl_setopt($curl, CURLOPT_FAILONERROR, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_ENCODING, "gzip");
var_dump(curl_exec($curl));
?>
