sina微博oauth第三方 登陆
SDK:https://github.com/JimLiu/WeiboSDK git
这篇文章具体谈谈在iOS上如何经过新浪微博帐户登陆应用。 github
在讨论这个以前，不得不说到OAuth。这是个什么玩意呢？按照官方的说法，OAuth是：An open protocol to allow secure API authorization in a simple and standard method from desktop and web applications. web
大概意思是说OAUTH是一种开放的协议，为桌面程序或者基于BS的web应用提供了一种简单的，标准的方式去访问须要用户受权的API服务。 objective-c
也就是说，经过OAuth，应用或者网站服务能够获取用户的受权，但又不会获取到用户的帐户信息（好比登陆名和密码）。这里的受权包括：容许向用户发送某些信息，容许向用户提供访问网站的权限等等。 编程
其实，对于大部分应用来讲，只须要验证用户是否属于新浪微博用户，若是属于，那也自动是个人用户，若是不属于，那么请用户就地注册一个帐户。换句话说，你将新浪微博的几亿用户自动认可成为你的网站用户，而不须要这几亿用户经过注册才能使用你的应用。因此，这是典型的一种YY思想，YY你瞬间得到了几亿用户！！ json
既然OAuth是一个协议，那么就须要用编程语言去实现它。目前，各类版本的OAuth基本均可以在google code下载到，包括C，C++，C#，JS，PHP等等。固然，确定会有objective-C，不然，我也不会写这篇文章了。 api
OK，假设已经有了一个版本的Objective-C的OAuth的实现。下面就利用它来实现微博帐户在iOS上的登陆。 浏览器
第一步：注册应用。 app
能够经过新浪微博的开放平台去注册一个应用。以后你会获得一个App Key和一个App Secret。拥有它们，你才能够申请权限。 编程语言
假设你的App Key是“1234567890”，App Secret是“abcdefghijklmnopqrstuvwxyz"
第二步：写代码。
将获取到的OAuth的objective-C版本加入你的project中。将你申请到的Key和Secret作为两个变量定义并赋值。
对于OAuth来讲，不少细节不须要咱们去关注的，只要知道几个重要的步骤便可：
1. 建立一个request，这个request包含key和secret的信息，用于向新浪微博申请得到对应用户的权限。
2. 经过request向新浪微博发出请求，告诉新浪微博说：我是一个合法的注册过的应用，如今准备向大人您申请得到用户的权限，请您高抬贵手。
3. 得到未受权的 Request Key。这个得到未受权的 Request Key就至关于放行条，也就是新浪微博容许你开始获取用户的权限。
4. 根据这个Request Key的内容，得到一个url地址，这个地址页面就是想登陆你应用的用户输入用户名和密码的地方。注意的是，这个url是属于新浪微博为你的这个应用建立的，是属于新浪微博的。调用iOS的接口，从浏览器打开这个url界面。
5. 用户在上述登陆界面输入本身的用户名和密码，成功登陆以后（实际上是新浪微博认证此用户是注册了新浪微博的用户），你能够得到已受权的 Access KEY。这个Access Key就包含了用户多登陆信息（包括昵称、用户ID等等，这里的昵称是指用户显示在新浪微博上的名字，而不是用户的登陆名）。
6. 到目前为止，你已经肯定用户是新浪微博的用户了，天然也是你的应用的用户（继续YY），因此接下去，你就赶忙容许用户登陆成功，进入你的应用主界面，享受你的应用程序了。还愣着干吗，翠花，上酸菜！！
找到一个objective-c实现的OAuth，而且对着每一步（第六步除外，第六步是在你本身的project中实现。你总不能让OAuth给你上酸菜吧），找到实现每一步功能的函数，而后加入你本身的project中。
