PHP encapsulates cURL tool classes and application examples

This article illustrates the PHP encapsulation of the cURL tool class. Share it for your reference, as follows:

CurlUtils tool classes:

<?php
/**
 * cURL Request tool class 
 */
class CurlUtils {
  private $ch;//curl Resource object 
  /**
   *  Construction method 
   * @param string $url  Requested address 
   * @param int $responseHeader  Whether response header information is required 
   */
  public function __construct($url,$responseHeader = 0){
    $this->ch = curl_init($url);
    curl_setopt($this->ch,CURLOPT_RETURNTRANSFER,1);// Set to return as a file stream 
    curl_setopt($this->ch,CURLOPT_HEADER,$responseHeader);// Sets whether the response header information is returned 
  }
  /**
   *  Destructional method 
   */
  public function __destruct(){
    $this->close();
  }
  /**
   *  Add a request header 
   * @param array $value  Request header 
   */
  public function addHeader($value){
    curl_setopt($this->ch, CURLOPT_HTTPHEADER, $value);
  }
  /**
   *  Send a request 
   * @return string  Data returned 
   */
  private function exec(){
    return curl_exec($this->ch);
  }
  /**
   *  Send get Request 
   * @return string  Data returned by request 
   */
  public function get(){
    return $this->exec();
  }
  /**
   *  Send post Request 
   * @param arr/string $value  Ready to send post Data of 
   * @param boolean $https  Whether it is https Request 
   * @return string     Data returned by request 
   */
  public function post($value,$https=true){
    if($https){
      curl_setopt($this->ch, CURLOPT_SSL_VERIFYPEER, FALSE);
      curl_setopt($this->ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    }
    curl_setopt($this->ch,CURLOPT_POST,1);// Settings post Request 
    curl_setopt($this->ch,CURLOPT_POSTFIELDS,$value);
    return $this->exec();
  }
  /**
   *  Shut down curl Handle 
   */
  private function close(){
    curl_close($this->ch);
  }
}

Invoke the instance:

Face Recognition Interface Based on face + +

$curl = new CurlUtils("https://api-cn.faceplusplus.com/facepp/v3/detect");// Create curl Object 
$value = ['api_key'=>'4Y7GS2sAPGEl-BtQlNw5Iqtq5jGOn87z','api_secret'=>'oQnwwJhS2mcm4vflKvgm972up9sLN8zj','image_url'=>'http://avatar.csdn.net/9/7/5/1_baochao95.jpg','return_attributes'=>'gender,age,glass'];// Prepare post Value of 
echo $curl->post($value);// Send a request
