API是应用程序的开发接口,在开发程序的时候,我们有些功能可能不需要从到到位去研发,我们可以拿现有的开发出来的功能模块来使用,而这个功能模块,就叫做库(libary)。比如说:要实现数据传输的安全,这就要使用加密技术,使用加密技术就要用到加密算法,而加密算法,已经有好心人,帮我们开发出来了加密算法库,你直接就可以调用,不需要再开发算法。
在技术交流群,大家有探讨稳定获取淘宝商品主图、价格、标题,及sku的完整解决方案。这个引起了我技术挑战的兴趣。
目前,自己做了压测,QPS高、出滑块概率极低,API整体稳定,可满足业务场景的性能需求。
1、get方式请求api接口
file_get_contents函数
$a = file_get_contents(“http://www.a.com”);
1.
如果接口返回json格式的数据,则要转为数组r e = j s o n d e c o d e ( re = json_decode(re=json
d
ecode(a,true);
1.
2、 post方式请求接口
curl扩展函数
function request_by_curl($remote_server,$post_string,$use_post=true) { if(function_exists('curl_init')){ $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$remote_server); if($use_post){ curl_setopt($ch,CURLOPT_POST, 1); curl_setopt($ch,CURLOPT_POSTFIELDS,$post_string); } curl_setopt($ch,CURLOPT_RETURNTRANSFER,true); $data = curl_exec($ch); curl_close($ch); return $data; }else{ return '请先安装curl'; }} $post_string为数组,如array("a"=>1)
3、curl扩展函数也用于get方式请求数据
查看curl是否安装,phpinfo():
4、返回示例获取密钥
