问题 This is very related to a previous question but I am having difficulties adapting for my use case. I have a sentence: "Forbes Asia 200 Best Under 500 Billion 2011" I have tokens like: oldTokens = [u'Forbes', u'Asia', u'200', u'Best', u'Under', u'500', u'Billion', u'2011'] And the indices of where a previous parser has figured out where there should be location or number slots: numberTokenIDs = {(7,): 2011.0, (2,): 200.0, (5,6): 500000000000.00} locationTokenIDs = {(0, 1): u'Forbes Asia'} The

0.传统网站访问工作流程原始的网站访问工作原理这样的访问再工业应用中存在的问题是，USER的账号和密码有可能再web请求过程中被破解。所以有如下新的授权方式 1. Token Auth 访问原理流程用户使用用户名和密码请求服务器服务器进行验证用户信息服务器通过验证发送给用户一个token 客户端存储token，并在每次请求时附上token 服务端验证token值，并返回数据 token内涵信息说明一个token就是一些信息的集合再token中包含足够多的信息，以便在后续的请求中减少查询数据库的几率服务端需要对cookie和HTTP Authrorization Header进行Token信息的检查基于上一点，你可以用一套token认证代码来面对浏览器类客户端和非浏览器类客户端；因为token是被签名的，所以我们可以认为一个可以解码认证通过的token是由我们系统发放的，其中带的信息是合法有效的； 3. 网络基本术语服务器是指通过网络向其他电脑提供信息或者服务的软件，称作“服务端/server” ----------------------服务器=服务端---------- 客户端是指负责接收和同用户交互的软件被称为客户端/client （任何一台计算机具备提供信息或服务的功能都能被称为服务器，只是现在专门的服务器根据需求做了特殊改进）参考

JWT(一)：认识 JSON WebToken JWT(二)：使用 Java 实现 JWT 介绍原理在上篇《JWT(一)：认识 JSON Web Token》已经说过了，实现起来并不难，你可以自己写一个 jwt 工具类（如果你有兴趣的话）当然了，重复造轮子不是程序员的风格，我们主张拿来主义！ JWT 官网提供了多种语言的 JWT 库，详情可以参考 https://jwt.io/#debugger 页面下半部分建议使用 jjwt库，它的github地址 https://github.com/jwtk/jjwt jjwt 版本 0.10.7，它和 0.9.x 有很大的区别，一定要注意！！！本文分5部分第1部分：以简单例子演示生成、验证、解析 jwt 过程第2部分：介绍 jjwt 的常用方法第3部分：封装一个常用的 jwt 工具类如果只是拿来主义，看到这里就可以了第4部分：介绍 jjwt 的各种签名算法第5部分：对 jwt 进行安全加密简单例子引入 MAVN 依赖 < dependency > < groupId > io.jsonwebtoken </ groupId > < artifactId > jjwt-api </ artifactId > < version > 0.10.7 </ version > </ dependency >

work节点配置kubelet 注: 所有work节点都要部署kubelet. kublet 运行在每个 worker 节点上,接收 kube-apiserver 发送的请求,管理 Pod 容器,执行交互式命令,如 exec、run、logs 等. kublet 启动时自动向 kube-apiserver 注册节点信息,内置的 cadvisor 统计和监控节点的资源使用情况. 为确保安全,本文档只开启接收 https 请求的安全端口,对请求进行认证和授权,拒绝未授权的访问(如 apiserver、heapster). 1.把kubelet的二进制执行文件分发到节点分发 [root@k8s-node1 bin]# cp kubelet kube-proxy /opt/k8s/bin/ [root@k8s-node1 bin]# scp kubelet kube-proxy root@k8s-node2:/opt/k8s/bin/ kubelet 100% 114MB 57.1MB/s 00:02 kube-proxy 100% 35MB 35.4MB/s 00:00 [root@k8s-node1 bin]# scp kubelet kube-proxy root@k8s-node3:/opt/k8s/bin/ kubelet 100% 114MB 57.1MB/s 00:02

How should I update an existing firebase token on my server when it gets refreshed by firebase?

阅读更多关于 How should I update an existing firebase token on my server when it gets refreshed by firebase?

问题 This question is about device groups and how to efficiently keep track of valid tokens. The problem I see is when a token is refreshed on a device and you send it to the server, how are you going to identify the old token that is not valid anymore. The device token is used to identify the device but it has been changed so there is no relation anymore between the device and the old token. Am i supposed to just check the validity of all the tokens that belong to a device group every now and
