PHP transmission session curl function Detailed explanation of the example
Preface:
Taking over the heavy responsibility of the person in charge of the PC side of the company's project, the responsibility is heavy; from demand analysis, drawing flow charts and building tables, Coding, testing, bug fixing, and online maintenance were all completed by myself as a polished commander (of course, I also had a front-end team with good skills, thanks to my supervisor for his help). Although it was tiring and I had to work a lot of overtime, I felt it was okay. The company was all the same. .
Not much to say, because projects often need to call the Java interface. Since the request interface is involved, there is the http request method. The common ones in PHP are GET/POST. Of course, there are other methods such as put, etc. GET/POST/PUT/DELETE are often used in Java. Of course, the request interface requires the use of curl-related functions. I hope everyone will read the documentation for debugging. The following are the related functions I have encapsulated (generally summarized, adjusted):
Sample code:
private $serverhost = "https://demo.xxx.cn"; //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, 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 $result;
}
//还有一个delete方式 大家自己参考文档调试下吧
上面3个请求方式都是单次请求(即请求一次)***************
PHP自带函数curl_multi_get_contents函数(thinkphp自带此函数，可以微调下)：
/**
* 批量发起请求 已调通
* curl multi POST数据
* */
public function curl_multi_get_contents($url=array(), $param = array(), $timeout=1000){

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
