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 $result;
 }
 //还有一个delete方式 大家自己参考文档调试下吧
上面3个请求方式都是单次请求(即请求一次)***************
PHP自带函数curl_multi_get_contents函数(thinkphp自带此函数，可以微调下)：
 /** 
 * 批量发起请求 已调通
 * curl multi POST数据
 * */
 public function curl_multi_get_contents($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);
 }
 }
 
 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);
 foreach($url as $uk=>$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();
 
 $param = $batchjoinclass; //二维数组 格式如下
 
 /*
 $param[1]['name'] = '班级新1';
 $param[1]['iamge'] = 'xxx11.png';
 $param[1]['iamgeType'] = 'CUSTOM';
 $param[2]['name'] = '班级新2';
 $param[2]['iamge'] = 'xxx.png';
 $param[2]['iamgeType'] = 'CUSTOM';
 */
 
 //获取请求url
 foreach($batchjoinclass as $key=>$val){
 $urlarr[$key] = $this->serverhost."/xxx/xxxx/xxxx/".$token;
 }
 
 $res = $this->curl_multi_get_contents($urlarr,$param);
 
 //格式化返回数据
 foreach($res as $key=>$val){
 $returndata[$key] = json_decode($val,true);
 }
 
 return $returndata;
 }
