PHP 传输会话curl函数的实例详解

　　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 = 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, 64256); $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, 64256); $uri = /xxx/xxx/xxx/.$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, 64256); } } 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; }
