PHP 传输会话curl函数的实例详解

前言：

接手公司项目PC端负责人的重担，责任担当重大；从需求分析，画流程图，建表，编码，测试修bug，上线维护等我一个光杆司令一人完成(当然还有一个技术不错的前端配合,感谢主管的帮助)，虽然累点加班多点但感觉还行吧，公司都是一个鸟样。

闲话不多说了，因为项目中经常需要调取java那边的接口，既然涉及到请求接口那就有了http的请求方式，PHP常见的是GET/POST两种当然还有其他的比如put等，java那边经常用到GET/POST/PUT/DELETE等方式，请求接口当然要用到curl的相关函数了，都是看文档调试的希望大家都看文档，下面是我封装好的相关函数等(大概总结下，已调通)：

示例代码：

serverhost.$url;

    $response = array();
    if($type == 'get'){ //get请求
      //请求头可以加其他设置
      $headers = array(
          'Content-type: application/json;charset=UTF-8',);
      $ch = curl_init();
      curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,CURLOPT_URL,$url);
      curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,CURLOPT_RETURNTRANSFER,true);
      curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,CURLOPT_FOLLOWLOCATION,TRUE);
      curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,CURLOPT_SSL_VERIFYPEER,0);
      curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,CURLOPT_HTTPHEADER,$headers);
      $response = curl_exec($ch);

   }elseif ($type == 'post'){  //post请求

     $headers = array(
        'Content-type: application/json;charset=UTF-8',);
     $ch = curl_init();
     curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,$url);
     curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,true);
     curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,TRUE);
     curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,CURLOPT_POST,true);  //注意这几行
     curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,CURLOPT_POSTFIELDS,$p<a href="https://www.jb51.cc/tag/ara/" target="_blank" class="keywords">ara</a>ms); //注意这几行
     //curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,CURLOPT_HEADER,0);
     curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,$headers);
     $response = curl_exec($ch);

   }elseif ($type == 'put'){ //put请求

      $headers = array(
           'Content-type: application/json;charset=UTF-8',);

      $ch = curl_init();
      curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,CURLOPT_PUT,true); //注意这几行
      curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,$p<a href="https://www.jb51.cc/tag/ara/" target="_blank" class="keywords">ara</a>ms);
      //curl_s<a href="https://www.jb51.cc/tag/eto/" target="_blank" class="keywords">eto</a>pt($ch,$headers);
      $response = curl_exec($ch);
   }

   return $response;
}

//如何调用上面代码
//get方式
/**

查询我创建过的班级
@param string $url 接口地址
@param string $params 参数
@param string $type 类型 get
@return array
*/
public function mycreateclass($userid){

$url = "/xxx/xxxx/xxxx/".$userid; //请求地址拼接
$response = $this->getcurldata($url,array(),"get");
$createdclass = json_decode($response,true); //返回json格式数据

return $createdclass;
}
/** post方式请求
用户登录判断
access public
@param string $username 用户名
@param string $password 密码
@return bool
*/
public function getlogin($username,$password)
{
//要post的数据
$params = array(
"username" => $username,"password" => $password
);
$params = json_encode($params,64|256);
$uri = "/xxx/xxx/login";
$response = $this->getcurldata($uri,"post");
$result = json_decode($response,true);

  return $result ;
}

 /*身份转换--put 请求
  */
 public function changeuserole($token){
     //要put的数据
    $p<a href="https://www.jb51.cc/tag/ara/" target="_blank" class="keywords">ara</a>ms = array();
    $p<a href="https://www.jb51.cc/tag/ara/" target="_blank" class="keywords">ara</a>ms = json_encode($p<a href="https://www.jb51.cc/tag/ara/" target="_blank" class="keywords">ara</a>ms,64|256);

    $uri = "/xxx/xxx/xxx/".$token."/";
    $response = $this->getcurldata($uri,"put");
    $result = json_decode($response,true);

    //dump($result);die;

    return $result;
 }

//还有一个delete方式大家自己参考文档调试下吧
上面3个请求方式都是单次请求(即请求一次)***
PHP 自带函数curl_multi_get_contents函数(thinkPHP 自带此函数，可以微调下)：
/**

*/
public function curl_multi_get_contents($url=array(),$param = array(),$timeout=1000){

$mh = curl_multi_init();

$curl_array[$uk] = curl_init();
}
unset($uk,$uv);

$options = array(

if (isset($param[$uk])) {
foreach ($param[$uk] as $_k => $_v) {
//$options[$_k] = $_v;
$optionsparam[$_k] = $_v;
$options[CURLOPT_POSTFIELDS] = json_encode($optionsparam,64|256);
}
}

curl_setopt_array($curl_array[$uk],$options);
curl_multi_add_handle($mh,$curl_array[$uk]);
unset($options);
}
unset($uk,$uv);
$running = NULL;
do {
curl_multi_exec($mh,$running);
} while($running > 0);

   $res = array();
   foreach($url as $uk=>$uv){
        $res[$uk] = curl_multi_getcontent($curl_array[$uk]);
   }
   unset($uk,$uv);

       curl_multi_remove_handle($mh,$curl_array[$uk]);
   }
  unset($url,$curl_array,$uk,$uv);
  curl_multi_close($mh);
  return $res;

}
//如何调用--批量发起请求
//批量请求加入班级
public function batchjoinclass($token,$batchjoinclass){
$urlarr = $param = $returndata = array();
