有些API要求请求的内容类型为application/x-www-form-urlencoded

function requestUrl($url,$data=null,$https=true,$method='post'){//1.初始化url$ch = curl_init($url);//2.设置相关的参数//字符串不直接输出,进行一个变量的存储curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);//判断是否为https请求if($https === true){curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);}//判断是否为post请求if($method == 'post'){curl_setopt($ch, CURLOPT_POST, true);curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));}curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type:application/x-www-form-urlencoded'));//3.发送请求$str = curl_exec($ch);//4.关闭连接curl_close($ch);//6.返回请求到的结果return $str;}
