爬虫怎么爬取接口
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。 

电商API接口 
item_get - 获得淘宝商品详情

注册测试

 

请求参数

请求参数：num_iid=520813250866&is_promotion=1

参数说明：num_iid:淘宝商品ID
is_promotion:是否获取取促销价

获取Key和secret

 

名称类型必须描述
keyString是调用key（必须以GET方式拼接在URL中）
secretString是调用密钥
api_nameString是API接口名称（包括在请求地址中）[item_search,item_get,item_search_shop等]
cacheString否[yes,no]默认yes，将调用缓存的数据，速度比较快
result_typeString否[json,jsonu,xml,serialize,var_export]返回数据格式，默认为json，jsonu输出的内容中文可以直接阅读
langString否[cn,en,ru]翻译语言，默认cn简体中文
versionString否API版本

 

 

  1. <?php
  2.  
  3. // 请求示例 url 默认请求参数已经URL编码处理
  4. // 本示例代码未加密secret参数明文传输，若要加密请参考：https://open.onebound.cn/help/demo/sdk/demo-sign.php
  5. $method = "GET";
  6. $url = "https://api-gw.onebound.cn/taobao/item_get/?key=<您自己的apiKey>&secret=<您自己的apiSecret>&num_iid=520813250866&is_promotion=1";
  7. $curl = curl_init();
  8. curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
  9. curl_setopt($curl, CURLOPT_URL, $url);
  10. curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,FALSE);
  11. curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,FALSE);
  12. curl_setopt($curl, CURLOPT_FAILONERROR, false);
  13. curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
  14. curl_setopt($curl, CURLOPT_HEADER, true);
  15. curl_setopt($curl, CURLOPT_ENCODING, "gzip");
  16. var_dump(curl_exec($curl));
  17. ?>

 API返回结果
