c/c++/curl实现facebook上传图片等功能
来源：互联网 发布：mac 打字反应很慢 编辑：程序博客网 时间：2024/06/05 01:13
翻了下以前的日记，决定把一些笔记晒出来分享，需求是这样，需要通过c/c++写的应用实现上传图片等到facebook,以下是用curl模拟的登录facebook，并取得权限的一些记录,有可能facebook的接口已经改了，但是原理是一样的,能用curl命令实现，c/c++就可以调用libcurl来实现程序控制的。
要有权限就得有access token
得到access token的一种方式
1. Embed a web browser and implement the client-side authentication flow:
https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&redirect_uri=https://www.facebook.com/connect/login_success.html&response_type=token
2. After the user authorizes your app, Facebook will redirect the user to that URL and pass an the access token in the URI fragment:
https://www.facebook.com/connect/login_success.html#
access_token=USER_ACCESS_TOKEN
You should detect this redirect and then read the access token out of the URI using whatever mechanisms provided by your OS and development framework of choice.
有了access token就可以做很多事，比如上传图片
facebook官方是没有c/c++的SDK的，怎么办，只能自己模拟了
浏览器上登录facebook
然后输入如下网址
www.facebook.com/dialog/oauth?client_id=1470040476543038&redirect_uri=https://www.facebook.com/connect/login_success.html&response_type=token&scope=publish_stream
FireBug调试过程得到

因为官方没有c/c++的SDK,目前facebook的原理是分析网页http数据，用curl模拟用户授权，登录，上传。 只要facebook改了页面，那么就得重新分析一次数据，然后再进行get post等的模拟。
有两个c++相关的代码，C++ REST SDK 与facebook-cpp-graph-api，似乎可用于windows

然后会跳转到一个成功页面

接着会要求写权限,照样会弹出一个要求确认的界面

因为官方没有c/c++的SDK,目前facebook的原理是分析网页http数据，用curl模拟用户授权，登录，上传。 只要facebook改了页面，那么就得重新分析一次数据，然后再进行get post等的模拟。
有两个c++相关的代码，C++ REST SDK 与facebook-cpp-graph-api，似乎可用于windows
其他的一些有用的资料：

This guide will take you through each step of the login flow and show you how to implement each one without using our SDKs:
