API接口数据集接口pytorch api接口获取数据

news2024/10/6 2:26:05

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
