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:

    private $serverhost = "https://demo.xxx.cn"; //测试
    /**
     * 请求接口封装  get/post/put/delete等
     * access public
     * @param string $url 接口地址
     * @param string $params 参数
     * @param string $type 类型 get/post/put/delete
     * @return bool/array
     */
     public function getcurldata($url,$params,$type="get"){
        $url = $this->serverhost.$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',
          );
          $ch = curl_init();
          curl_setopt($ch, curlopt_url, $url);
          curl_setopt($ch, curlopt_returntransfer, true);
          curl_setopt($ch, curlopt_followlocation, true);
          curl_setopt($ch, curlopt_ssl_verifypeer, 0);
          curl_setopt($ch, curlopt_httpheader, $headers);
          $response = curl_exec($ch);
 
       }elseif ($type == 'post'){  //post请求
 
         $headers = array(
            'content-type: application/json;charset=utf-8',
         );
         $ch = curl_init();
         curl_setopt($ch, curlopt_url, $url);
         curl_setopt($ch, curlopt_returntransfer, true);
         curl_setopt($ch, curlopt_followlocation, true);
         curl_setopt($ch, curlopt_post, true);  //注意这几行
         curl_setopt($ch, curlopt_postfields, $params); //注意这几行
         //curl_setopt($ch, curlopt_header, true);
         curl_setopt($ch, curlopt_ssl_verifypeer, 0);
         curl_setopt($ch, curlopt_httpheader, $headers);
         $response = curl_exec($ch);
 
       }elseif ($type == 'put'){ //put请求
 
          $headers = array(
               'content-type: application/json;charset=utf-8',
          );
 
          $ch = curl_init();
          curl_setopt($ch, curlopt_url, $url);
          curl_setopt($ch, curlopt_returntransfer, true);
          curl_setopt($ch, curlopt_followlocation, true);
          curl_setopt($ch, curlopt_put, true); //注意这几行
          curl_setopt($ch, curlopt_postfields, $params);
          //curl_setopt($ch, curlopt_header, true);
          curl_setopt($ch, curlopt_ssl_verifypeer, 0);
          curl_setopt($ch, curlopt_httpheader, $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,$params,"post");
      $result = json_decode($response, true);
 
      return $result ;
    }
     
     /*身份转换--put 请求
      */
     public function changeuserole($token){
         //要put的数据
        $params = array();
        $params = json_encode($params, 64|256);
 
        $uri = "/xxx/xxx/xxx/".$token."/";
        $response = $this->getcurldata($uri,$params,"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):
     /**
