| 副标题[/!--empirenews.page--] 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',);
      $ch = curl_init();
      curl_setopt($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,$url);
     curl_setopt($ch,true);
     curl_setopt($ch,TRUE);
     curl_setopt($ch,CURLOPT_POST,true);  //注意这几行
     curl_setopt($ch,CURLOPT_POSTFIELDS,$params); //注意这几行
     //curl_setopt($ch,CURLOPT_HEADER,0);
     curl_setopt($ch,$headers);
     $response = curl_exec($ch);
   }elseif ($type == 'put'){ //put请求
      $headers = array(
           'Content-type: application/json;charset=UTF-8',);
      $ch = curl_init();
      curl_setopt($ch,CURLOPT_PUT,true); //注意这几行
      curl_setopt($ch,$params);
      //curl_setopt($ch,$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
    $params = array();
    $params = json_encode($params,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):
 /**
 
批量发起请求 已调通
curl multi POST数据
*/public function curl_multi_get_contents($url=array(),$param = array(),$timeout=1000){
 $userAgent = 'Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1)';
 $headers = array(
 'Content-type: application/json;charset=UTF-8',);
 $curl_array=array();
 $mh = curl_multi_init();
 foreach($url as $uk=>$uv){
 $curl_array[$uk] = curl_init();
 }
 unset($uk,$uv);
 foreach($url as $uk=>$uv) {
 $options = array(
 CURLOPT_URL   => $uv,CURLOPT_TIMEOUT => $timeout,CURLOPT_RETURNTRANSFER => true,CURLOPT_DNS_CACHE_TIMEOUT => 86400,CURLOPT_DNS_USE_GLOBAL_CACHE  => true,CURLOPT_SSL_VERIFYPEER => 0,CURLOPT_HEADER => false,CURLOPT_USERAGENT  => 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)',CURLOPT_HTTPHEADER => $headers,);
 if (isset($param[$uk])) {
 foreach ($param[$uk] as $_k => $_v) {
 //$options[$_k] = $_v;
 $optionsparam[$_k] = $_v;
 $options[CURLOPT_POSTFIELDS] = json_encode($optionsparam,64|256);
 }
 }
