自己筆記 - 使用 Facebook API (一) @ 小雕雕的家

因為工作需要,要寫類似心理測驗的東東

所以開始研究 facebook 的 API 但是.........網路上一堆看到的都是 C#

VB.net 的範例少的可憐,再加上這個 SDK 提供的也是 C# 飯粒

那是要我去死嗎,當然是男人就一定要先寫寫看再說

還好 C# 都看的懂只是寫不出來,因此就只好自己轉

然後要開發 facebook 的應用程式基本上可以不用這SDK

只是已經有人包裝好了不用可惜

要用的話可以到這篇來看 (c#)

第一步當然就是下載 SDK http://facebooktoolkit.codeplex.com/

第二步加入 facebook developer,然後建立新應用程式與設定

(詳細設定過程就看上面連結的 MSDN 黃老師教學)

http://www.facebook.com/developers/

第三步寫 code
我只是轉成 VB.net

web.config

=====================================================
  <appSettings>
   <add key="ApiKey" value="輸入API 金鑰"/>
   <add key="Secret" value="輸入應用程式密鑰"/>
   <add key="Callback" value="http://localhost:4053/"/>
   <add key="Suffix" value=" testapp_tw_r"/>
  </appSettings>

Default.aspx

=====================================================

1.無用的 HTML tag 拿掉,ex : body,head,meta

2.隨便拉一個 Gridview到頁面上

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="FB._Default" %>
<%@ Register Assembly="Facebook.Web" Namespace="Facebook.Web.FbmlControls" TagPrefix="cc1" %>
   <form id="form1" runat="server">
   <div>
   <asp:gridview id="GridView1" runat="server">
   <Columns>
   <asp:ImageField DataImageUrlField="pic_small">
   </asp:ImageField>
   </Columns>
   </asp:gridview>
   </div>
   </form>

Default.aspx.vb

=====================================================
