1.亲测，话不多说直接上代码

$curl = curl_init();
curl_setopt_array($curl, array(CURLOPT_URL => "http://www.m58.link/api/url/add",CURLOPT_RETURNTRANSFER => true,CURLOPT_ENCODING => "",CURLOPT_MAXREDIRS => 2,CURLOPT_TIMEOUT => 10,CURLOPT_FOLLOWLOCATION => true,CURLOPT_CUSTOMREQUEST => "POST",CURLOPT_HTTPHEADER => array("Authorization: Bearer dQCBbvZTfDrRpXAQ", //Bearer 后面填你的key"Content-Type: application/json",),CURLOPT_POSTFIELDS => '{"url": "https://baidu.com","type": "direct"
}',
));$response = curl_exec($curl);curl_close($curl);
echo $response;

2.url填你需要转换的网址，key要怎么申请呢，去免费短链接网站m58注册一个号就行了，地址www.m58.link
