spring-cloud-starter-oauth2

1、OAuth2.0简介

OAuth（开发授权）是一个开放标准，允许用户授权第三方应用访问他们存储在另外的服务提供者上的信息，而不需要将用户名和密码提供给第三方应用或分享他们数据的所有内容。

OAuth2.0是OAuth的延续，但他并不兼容OAuth1.0，即它完全废除OAuth1.0。很多大公司如Google，Yahoo，Microsoft等都提供了OAuth认证服 务，这些都足以说明OAUTH标准逐渐成为开放资源授权的标准。

微信小程序授权登录同样也是提供OAuth认证服务

2、业务场景

第三方认证

当需要访问第三方系统的资源时需要首先通过第三方系统的认证（例如：微信认证），由第三方系统对用户认证通过，并授权资源的访问权限。

你恰好之前在我们的B网站上注册过账号，那么现在就可以使用B网站上的账号登录在CSDN上。那么我们在B网站上做这样的一个功能就是使用OAuth2做的。

OAuth2.0包含一下几种角色

1，客户端：本身不存储资源，需要通过资源拥有者的授权去请求资源服务器的资源。

2，资源拥有者：通常为用户，也可以是应用程序，即该资源的拥有者。

3，授权服务器（认证服务器）：用于服务提供商对资源拥有者的身份认证，对访问资源进行授权，认证成功后会给客户端发放令牌（access_token），作为客户端访问资源服务器的凭据。

4，资源服务器：存储资源的服务器

5，客户端标识：client_id

6，客户端密钥：client_secret

为什么要有client_id和client_secret呢？

因为服务提供商不能允许随便一个客户端就接入到它的授权服务器，服务提供商会 给准入的接入方一个身份，用于接入时的凭据。

3，环境搭建

  1. 项目工程

shop-oauth-service 认证服务（颁发Token）

shop-gateway-service 网关（认证用户的请求 也即认证Token）

shop-service 服务（资源服务）

4.资源服务授权流程

  1. 钥私钥授权流程

上图的业务流程如下:

  1. 客户端请求认证服务申请令牌
  2. 认证服务生成令牌认证服务采用非对称加密算法，使用私钥生成令牌。
  3. 客户端携带令牌访问资源服务客户端在Http header 中添加： Authorization：Bearer 令牌。
  4. 资源服务请求认证服务校验令牌的有效性资源服务接收到令牌，使用公钥校验令牌的合法性。
  5. 令牌有效，资源服务向客户端响应资源信息
2.公钥私钥

在对称加密的时代，加密和解密用的是同一个密钥，这个密钥既用于加密，又用于解密。这样做有一个明显的缺点，如果两个人之间传输文件，两个人都要知道密钥，如果是三个人呢，五个人呢？于是就产生了非对称加密，用一个密钥进行加密（公钥），用另一个密钥进行解密（私钥）。

总结：公钥加密、私钥解密、私钥签名、公钥验签。

3. 生成私钥公钥

Spring Security 提供对JWT的支持，本节我们使用Spring Security 提供的JwtHelper来创建JWT令牌，校验JWT令牌 等操作。 这里JWT令牌我们采用非对称算法进行加密，所以我们要先生成公钥和私钥。

(1)生成密钥证书 下边命令生成密钥证书，采用RSA 算法每个证书包含公钥和私钥

创建一个文件夹，在该文件夹下执行如下命令行：

keytool -genkeypair -alias qianggou -keyalg RSA -keypass qianggou -keystore qianggou.jks -storepass qianggou

Keytool 是一个java提供的证书管理工具

  1. -alias：密钥的别名 
  2. -keyalg：使用的hash算法 
  3. -keypass：密钥的访问密码 
  4. -keystore：密钥库文件名，qianggou.keystore保存了生成的证书 
  5. -storepass：密钥库的访问密码

查询证书信息

keytool -list -keystore qianggou.jks

删除别名

keytool -delete -alias qianggou -keystore qianggou.jsk
4.导出公钥

openssl是一个加解密工具包，这里使用openssl来导出公钥信息。

安装 openssl：http://slproweb.com/products/Win32OpenSSL.html

安装资料目录下的Win64OpenSSL-1_1_0g.exe

配置openssl的path环境变量，如下图：

本教程配置在C:\OpenSSL-Win64\bin

cmd进入qianggou.jks文件所在目录执行如下命令(如下命令在windows下执行，会把-变成中文方式，请将它改成英文的-)：

keytool -list -rfc --keystore qianggou.jks | openssl x509 -inform pem -pubkey

下面段内容是公钥

  1. -----BEGIN PUBLIC KEY-----
  2. MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAhTN8iyCyQEZPUmLw0GB0
  3. rH0xeT23w4c8X8thfEtphIBTAKOoUKHxhzBHra/WHLpPw/fV/m9KTvbWCdlBziKW
  4. r4P//KtUoa5D3qJupsPDxl9GTXJjG/9y/E+9hHLtl+cM2Qu+RTayFQ4X4ZqLjiOc
  5. lZZjN8g3MUomu45ab7PVJvuNUGcMq8s+pSvIwHQejYVKlPH8amSqyyxEyzH2MFBX
  6. N1c0KoerMfaDV0uzFCsUdOxUlpow9byCPZAspuNbN3DG3xwoHtOErWcchs8TlGMy
  7. So2QAeGADmCkH/iIHbF22ytmybIsbK5Ww9T+a1xK+wzzKBAucL+HuK5hLwQlSyuq
  8. zQIDAQAB
  9. -----END PUBLIC KEY-----

将上边的公钥拷贝到文本public.key文件中，合并为一行,可以将它放到需要实现授权认证的工程中。

5.运行图

在运行之前我们再来梳理一下流程
