區(qū)別OpenId: Authentication :認(rèn)證
OpenID當(dāng)你需要訪問A網(wǎng)站的時(shí)候,A網(wǎng)站要求你輸入你的OpenId,即可跳轉(zhuǎn)到你的OpenId服務(wù)網(wǎng)站,輸入用戶名和密碼之后,再調(diào)回A網(wǎng)站，則認(rèn)證成功。 OAuth2.0OAuth是一個(gè)關(guān)于授權(quán)的開放網(wǎng)絡(luò)協(xié)議,允許用戶讓第三方應(yīng)用訪問該用戶在在某一網(wǎng)站上的資源，而無需提供用戶名和密碼給第三方。
OpenID --(OpenID Connect) 簡(jiǎn)稱OIDCOpenID Connect是OpenID的升級(jí)版，簡(jiǎn)稱OIDC，是2014年初發(fā)布的開放標(biāo)準(zhǔn)，定義了一種基于OAuth2的可互操作的方式來來提供用戶身份認(rèn)證。在OIDC中，應(yīng)用程序不必再為每個(gè)客戶端構(gòu)建不同的協(xié)議，而是可以將一個(gè)協(xié)議提供給多個(gè)客戶端，它還使用了JOSN簽名和加密規(guī)范，用來在傳遞攜帶簽名和加密的信息，并使用簡(jiǎn)單的REST/JSON消息流來實(shí)現(xiàn)，和之前任何一種身份認(rèn)證協(xié)議相比，開發(fā)者都可以輕松的集成。簡(jiǎn)單說 OIDC是在OAuth2.0之上的一個(gè)擴(kuò)展 ID Tokens IdentityServer4現(xiàn)在的應(yīng)用開發(fā)層出不窮，基于瀏覽器的網(wǎng)頁(yè)應(yīng)用，基于微信的公眾號(hào)、小程序，基于IOS、Android的App，基于Windows系統(tǒng)的桌面應(yīng)用和UWP應(yīng)用等等，這么多種類的應(yīng)用，就給應(yīng)用的開發(fā)帶來的挑戰(zhàn)，我們除了分別實(shí)現(xiàn)各個(gè)應(yīng)用外，我們還要考慮各個(gè)應(yīng)用之間的交互，通用模塊的提煉，其中身份的認(rèn)證和授權(quán)就是每個(gè)應(yīng)用必不可少的的一部分。而現(xiàn)在的互聯(lián)網(wǎng)，對(duì)于信息安全要求又十分苛刻，所以一套統(tǒng)一的身份認(rèn)證和授權(quán)就至關(guān)重要。
JwtBearer 認(rèn)證
Bearer認(rèn)證（也叫做令牌認(rèn)證）是一種HTTP認(rèn)證方案，其中包含的安全令牌的叫做Bearer Token。因此Bearer認(rèn)證的核心是Token。那如何確保Token的安全是重中之重。一種方式是使用Https，另一種方式就是對(duì)Token進(jìn)行加密簽名。而JWT就是一種比較流行的Token編碼方式。 JWT（Json Web Token)
JWT有三部分組成：
Header：由alg和typ組成，alg是algorithm的縮寫，typ是type的縮寫，指定token的類型。該部分使用Base64Url編碼。 ASP.NET授權(quán)認(rèn)證（OWIN、Katana）ASP.NET現(xiàn)有的的asp.net是成熟且功能豐富的運(yùn)行時(shí)和開發(fā)人員編程模型,同時(shí)這個(gè)框架已整體式，各種不同邏輯的功能單元都緊密耦合在System.web.dll程序集中。作為更大的.NET Framework更新周期基本以年為單位。開發(fā)團(tuán)隊(duì)采用了幾個(gè)進(jìn)化步驟將ASP.NET作為可插入的一系列組件而不是單一框架。
OWINOWIN定義了.NET Web服務(wù)器和Web應(yīng)用程序之間的標(biāo)準(zhǔn)接口。OWIN接口的目標(biāo)是分離服務(wù)器和應(yīng)用程序。 Katana用于Microsoft服務(wù)器和框架的OWIN實(shí)現(xiàn) 優(yōu)勢(shì)
