JSON 网络令牌JWT(JSON Web Token)
参考:https://zhuanlan.zhihu.com/p/12876076909
1、什么是JWT?
JWT(JSON Web Token)是一种开放标准(RFC 7519),用于在各方之间以 JSON 格式安全地传输信息。它通常用于身份验证和授权流程中,特别是在无状态的 RESTful API 和现代 Web 应用中。
2、什么时候应该使用 JSON Web Token?
以下是 JSON Web Token (JWT) 的一些适用场景:
授权(Authorization): 这是 JWT 最常见的用途。用户登录后,后续的每个请求都会携带 JWT,从而允许用户访问该令牌所授权的路由、服务和资源。单点登录(Single Sign On)是当前广泛使用 JWT 的一个功能,因为它具有较小的开销,并且可以轻松跨不同域名使用。
信息交换(Information Exchange): JWT 是在各方之间安全传输信息的一种好方式。由于 JWT 可以签名(例如,使用公钥/私钥对),你可以确认发送者的身份。此外,由于签名是基于头部(header)和负载(payload)计算得出的,你还可以验证内容是否被篡改。
3、JSON Web Token 的结构是什么?
在紧凑形式中,JSON Web Token(JWT)由三部分组成,各部分之间通过点号(.)分隔:
头部(Header)
负载(Payload)
签名(Signature)
JWT有效期可以在 $payload 中设置(建议),也可以通过在 $secretKey 原有秘钥后加日期,动态改变秘钥来实现
PHP生成和验证jwt
//生成JWT令牌
function jwt_create($payload, $secretKey){
function base64url_encode($data){return rtrim(strtr(base64_encode($data), '+/', '-_'), '=');}
// 定义 Header、Payload 和密钥
$header = array('alg' => 'HS256');
// 编码 Header 和 Payload
$headerEncoded = base64url_encode(json_encode($header));
$payloadEncoded = base64url_encode(json_encode($payload));
// 生成签名(HMAC-SHA256)
$signatureInput = "$headerEncoded.$payloadEncoded";
$signature = hash_hmac('sha256', $signatureInput, $secretKey, true);
$signatureEncoded = base64url_encode($signature);
// 组合完整 JWT
$jwt = "$headerEncoded.$payloadEncoded.$signatureEncoded";
return $jwt;
}
//验证JWT令牌并获取数据
function jwt_verify($jwt,$secretKey){
function base64url_encode($data){return rtrim(strtr(base64_encode($data), '+/', '-_'), '=');}
function base64url_decode($data) {$padding = strlen($data) % 4; if($padding > 0){$data .= str_repeat('=', 4 - $padding);} return base64_decode(strtr($data, '-_', '+/'));}
// 提取已生成的 JWT 各部分
list($header, $payload, $signature) = explode('.', $jwt);
// 重新计算签名
$recomputedSignature = base64url_encode(
hash_hmac('sha256', "$header.$payload", $secretKey, true)
);
// 比较签名
if($signature === $recomputedSignature){
$res=json_decode(base64url_decode($payload),true);
if(is_array($res) && isset($res['userid']))return $res['userid'];
}
return false;
}php获取指定目录的所有子孙目录
方法一:scandir + 递归
function getAllSubdirectories($path) {
$subdirs = [];
$items = scandir($path);
foreach ($items as $item) {
if ($item === '.' || $item === '..') continue;
$fullPath = $path . DIRECTORY_SEPARATOR . $item;
if (is_dir($fullPath)) {
// 添加当前目录
$subdirs[] = $fullPath;
// 递归获取子目录的子目录
$subdirs = array_merge($subdirs, getAllSubdirectories($fullPath));
}
}
return $subdirs;
}
// 使用示例
$allSubdirs = getAllSubdirectories('/path/to/directory');
print_r($allSubdirs);
方法二:使用 RecursiveDirectoryIterator(推荐)
function getAllSubdirectoriesIterator($path) {
$subdirs = [];
$iterator = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($path, RecursiveDirectoryIterator::SKIP_DOTS),
RecursiveIteratorIterator::SELF_FIRST
);
foreach ($iterator as $fileinfo) {
if ($fileinfo->isDir()) {
$subdirs[] = $fileinfo->getPathname();
}
}
return $subdirs;
}
// 使用示例
$allSubdirs = getAllSubdirectoriesIterator('/path/to/directory');
print_r($allSubdirs);
分别用js、php实现GS84与GCJ02两种坐标系的互转
高德地图: 使用 GCJ-02 坐标系,也称为火星坐标系。它是基于国际标准 WGS-84 坐标系进行加密处理得到的。
百度地图: 采用 BD-09 坐标系,这是在 GCJ-02 基础上进行二次加密而来的,具有更高的安全性和隐私保护。
天地图: 使用 CGCS2000 坐标系,该坐标系与 WGS-84 存在微小偏差,在要求不高的情况下可以直接与 WGS-84 互换使用。
