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(大概下，已调通)：

示例代码：

private $serverhost = "https://demo.xxx.cn"; //测试

/**

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

/**

/

/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

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)：

/**

$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_mult/

/i_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

/*

$param1 = '班级新1';

$param1 = 'xxx11.png';

$param1 = 'CUSTOM';

$param2 = '班级新2';

$param2 = 'xxx.png';

$param2 = '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;

}
