PHP 傳輸會話curl函數的實例詳解
前言：
接手公司項目PC端負責人的重擔，責任擔當重大；從需求分析，畫流程圖，建表，編碼，測試修bug，上線維護等我一個光桿司令一人完成(當然還有一個技術不錯的前端配合,感謝主管的幫助)，雖然累點加班多點但感覺還行吧，公司都是一個鳥樣。
閑話不多說了，因為項目中經常需要調取java那邊的接口，既然涉及到請求接口那就有了http的請求方式，PHP常見的是GET/POST兩種當然還有其他的比如put等，java那邊經常用到GET/POST/PUT/DELETE等方式，請求接口當然要用到curl的相關函數了，都是看文檔調試的希望大家都看文檔，下面是我封裝好的相關函數等(大概總結下，已調通)：
示例代碼：
private $serverhost = "https://demo.xxx.cn"; //測試
/**
* 請求接口封裝 get/post/put/delete等
* access public
* @param string $url 接口地址
* @param string $params 參數
* @param string $type 類型 get/post/put/delete
* @return bool/array
*/
public function getcurldata($url,$params,$type="get"){
$url = $this->serverhost.$url;
$response = array();
if($type == 'get'){ //get請求
//請求頭可以加其他設置
$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請求
$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); //注意這幾行
curl_setopt($ch, CURLOPT_POSTFIELDS, $params); //注意這幾行
//curl_setopt($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請求
$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); //注意這幾行
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;
}
//如何調用上面代碼
//get方式
/**
* 查詢我創建過的班級
* @param string $url 接口地址
* @param string $params 參數
* @param string $type 類型 get
* @return array
*/
public function mycreateclass($userid){
$url = "/xxx/xxxx/xxxx/".$userid; //請求地址拼接
$response = $this->getcurldata($url,array(),"get");
$createdclass = json_decode($response, true); //返回json格式數據
return $createdclass;
}
/** post方式請求
* 用戶登錄判斷
* access public
* @param string $username 用戶名
* @param string $password 密碼
* @return bool
*/
public function getlogin($username,$password)
{
//要post的數據
$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 $result ;
}
/*身份轉換--put 請求
*/
public function changeuserole($token){
//要put的數據
$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;
}
//還有一個delete方式 大家自己參考文檔調試下吧
上面3個請求方式都是單次請求(即請求一次)***************
PHP自帶函數curl_multi_get_contents函數(thinkphp自帶此函數，可以微調下)：
/**
