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：
$response = array();
if($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;

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 -
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)：
/**
-

-

-
*/
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
/*

//格式化返回数据
