php curl操作API接口类完整示例

本文实例讲述了php curl操作API接口类。分享给大家供大家参考，具体如下：

requestType = strtolower($requestType);
  $paramUrl = '';
  // PATHINFO模式
  if (!empty($data)) {
   foreach ($data as $key => $value) {
    $paramUrl.= $key . '=' . $value.'&';
   }
   $url = $url .'?'. $paramUrl;
  }
  //初始化类中的数据
  $this->url = $url;
  $this->data = $data;
  try{
   if(!$this->curl = curl_init()){
    throw new Exception('curl初始化错误：');
   };
  }catch (Exception $e){
   echo '
';
   print_r($e->getMessage());
   echo '
';
  }
  curl_setopt($this->curl, CURLOPT_URL, $this->url);
  curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, 1);
  //curl_setopt($this->curl, CURLOPT_HEADER, 1);
 }
 /**
  * [_post 设置get请求的参数]
  * @return [type] [description]
  */
 public function _get() {
 }
 /**
  * [_post 设置post请求的参数]
  * post 新增资源
  * @return [type] [description]
  */
 public function _post() {
  curl_setopt($this->curl, CURLOPT_POST, 1);
  curl_setopt($this->curl, CURLOPT_POSTFIELDS, $this->data);
 }
 /**
  * [_put 设置put请求]
  * put 更新资源
  * @return [type] [description]
  */
 public function _put() {
  curl_setopt($this->curl, CURLOPT_CUSTOMREQUEST, 'PUT');
 }
 /**
  * [_delete 删除资源]
  * delete 删除资源
  * @return [type] [description]
  */
 public function _delete() {
  curl_setopt($this->curl, CURLOPT_CUSTOMREQUEST, 'DELETE');
 }
 /**
  * [doRequest 执行发送请求]
  * @return [type] [description]
  */
 public function doRequest() {
  //发送给服务端验证信息
  if((null !== self::token) && self::token){
   $this->headers = array(
    'Client-Token:'.self::token,//此处不能用下划线
    'Client-Code:'.$this->setAuthorization()
   );
  }
  //发送头部信息
  $this->setHeader();
  //发送请求方式
  switch ($this->requestType) {
   case 'post':
    $this->_post();
    break;
   case 'put':
    $this->_put();
    break;
   case 'delete':
    $this->_delete();
    break;
   default:
    curl_setopt($this->curl, CURLOPT_HTTPGET, TRUE);
    break;
  }
  //执行curl请求
  $info = curl_exec($this->curl);
  //获取curl执行状态信息
  $this->status = $this->getInfo();
  return json_decode($info);
 }
 /**
  * 设置发送的头部信息
  */
 private function setHeader(){
  curl_setopt($this->curl, CURLOPT_HTTPHEADER, $this->headers);
 }
 /**
  * 生成授权码
  * @return string 授权码
  */
 private function setAuthorization(){
  $authorization = md5(substr(md5(self::token), 8, 24).self::token);
  return $authorization;
 }
 /**
  * 获取curl中的状态信息
  */
 public function getInfo(){
  return curl_getinfo($this->curl);
 }
 /**
  * 关闭curl连接
  */
 public function __destruct(){
  curl_close($this->curl);
 }
}
