PHP 传输会话curl函数的实例详解
媒介:
接办公司项目PC端认真人的重担,责任继续重大;从需求说明,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(虽然尚有一个技能不错的前端共同,感激主管的辅佐),固然累点加班多点但感受还行吧,公司都是一个鸟样。
闲话不多说了,由于项目中常常必要调取java何处的接口,既然涉及到哀求接口那就有了http的哀求方法,PHP常见的是GET/POST两种虽然尚有其他的好比put等,java何处常常用到GET/POST/PUT/DELETE等方法,哀求接口虽然要用到curl的相干函数了,都是看文档调试的但愿各人都看文档,下面是我封装好的相干函数等(或许总结下,已调通):
示例代码:
serverhost.$url;
$response = array();
if($type == 'get'){ //get哀求
//哀求头可以加其他配置
$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哀求
$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); //留意这几行
curl_setopt($ch,CURLOPT_POSTFIELDS,$params); //留意这几行
//curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch,$headers);
$response = curl_exec($ch);
}elseif ($type == 'put'){ //put哀求
$headers = array(
'Content-type: application/json;charset=UTF-8',);
$ch = curl_init();
curl_setopt($ch,CURLOPT_PUT,true); //留意这几行
curl_setopt($ch,$params);
//curl_setopt($ch,$headers);
$response = curl_exec($ch);
}
return $response;
}
//怎样挪用上面代码
//get方法
/**
-
查询我建设过的班级
-
@param string $url 接口地点
-
@param string $params 参数
-
@param string $type 范例 get
-
@return array
*/
public function mycreateclass($userid){
$url = "/xxx/xxxx/xxxx/".$userid; //哀求地点拼接
$response = $this->getcurldata($url,array(),"get");
$createdclass = json_decode($response,true); //返回json名目数据
return $createdclass;
}
/** post方法哀求
-
用户登录判定
-
access public
-
@param string $username 用户名
-
@param string $password 暗码
-
@return bool
*/
public function getlogin($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 $result ;
}
/*身份转换--put 哀求
*/
public function changeuserole($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 $result;
}
//尚有一个delete方法 各人本身参考文档调试下吧
上面3个哀求方法都是单次哀求(即哀求一次)***
PHP自带函数curl_multi_get_contents函数(thinkphp自带此函数,可以微调下):
/**
-
批量提倡哀求 已调通
-
curl multi POST数据
-
*/
public function curl_multi_get_contents($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);
}
}
