新浪微博PC客户端（DotNet WinForm版）——功能实现分解介绍
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
上一篇：新浪微博PC客戶端（DotNet WinForm版）—— 初探
?
說明一下：只是興趣，并不是想發(fā)布為一個軟件，說實在的，如果要作為一個軟件發(fā)布，要做的工作還有很多。?
?
新浪微博API地址：http://open.t.sina.com.cn/wiki/index.php/API%E6%96%87%E6%A1%A3?retcode=0。
目前提供的SDK：
?
- 1?Adobe Air
- 2?Flash SDK
- 3?PHP
- 4?C++
- 5?C#
- 6?Java SDK
- 7?Python SDK
- 8?Javascript SDK(JSSDK)
- 9?iOS SDK
- 10?OAuth Library
其它的不清楚，C#的還不完善，而且不是官方的。
?
當前已實現(xiàn)的功能：
?1、HTTP普通鑒權(quán)(Basic Authentication)的身份驗證方式，說白了就是每次訪問API都要發(fā)送帳號和密碼，當然是不安全的，但是相比OAuth驗證方式門檻要低的多。要使用OAuth驗證方式可以去看下SDK。
===》account/verify_credentials?驗證當前用戶身份是否合法?
?
OAuth是一種國際通用的授權(quán)方式，它的特點是不需要用戶在第三方應用輸入用戶名及密碼。OAuth的技術(shù)說明可參看官方網(wǎng)站 http://oauth.net。學習和研究OAuth的意義不僅僅在于新浪圍脖，而是對以后開發(fā)類似的項目非常有意義和價值（如果你還不知道OAuth授權(quán)方式）。
?
驗證通過則返回用戶的個人信息，參照下面的API字段說明。
API字段說明
- status?微博信息內(nèi)容
- user?用戶資料信息
- comment?評論信息描述
- direct_message?私信信息
- 省份城市編碼表
?
上一篇說了，API返回的結(jié)果格式有兩種：XML和JSON，在調(diào)用API的時候可以指定。
這里我指定的是XML格式，實現(xiàn)代碼如下：
登錄窗體：FrmLogin.cs，可以看上一篇的截圖。?
（1）把申請AppKey和AppSecret寫到app.config?
<? xml?version="1.0"?encoding="utf-8"? ?>< configuration >
?? < appSettings >
???? < add? key ="AppKey" ?value ="3476523072" />
???? < add? key ="AppSecret" ?value ="3c909770efa6865fd5843a564545826d" />
?? </ appSettings >
</ configuration >
?
要申請AppKey,需要登錄新浪圍脖，然后在這個地址創(chuàng)建應用并生成：?http://open.t.sina.com.cn/apps/new。
（2）創(chuàng)建了一個靜態(tài)類，保存用戶信息?
代碼 using ?System;using ?System.Collections.Generic;
using ?System.Linq;
using ?System.Text;
using ?System.Runtime.Serialization;
namespace ?MBClient.Entities
{
???? /// ? <summary>
???? /// ?微博帳號資料
???? /// ? </summary>
???? internal ? class ?UserInfo
????{
???????? internal ?UserInfo(){?}
???????? internal ? static ? string ?UserName?{? get ;? set ;?}
???????? internal ? static ? string ?Password?{? get ;? set ;?}
???????? internal ? static ? string ?UserNamePassword?{? get ;? set ;?}
???????? internal ? static ? int ?ID?{? get ;? set ;?}

???????? internal ? static ? int ?StatusesCount?{? get ;? set ;?}
???????? internal ? static ? int ?FavouritesCount?{? get ;? set ;?}
???????? /// ? <summary>
???????? /// ?微博帳號日期

???????? internal ? static ? string ?CreatedAt?{? get ;? set ;?}
???????? internal ? static ? bool ?Following?{? get ;? set ;?}
???????? internal ? static ? bool ?Verified?{? get ;? set ;?}
???????? internal ? static ? bool ?AllowAllActMsg?{? get ;? set ;?}
???????? internal ? static ? bool ?GeoEnabled?{? get ;? set ;?}
????}
}
?
??
（3）調(diào)用API?
代碼 using ?System;using ?System.Collections.Generic;
using ?System.Text;
using ?System.IO;
using ?System.Net;
using ?MBClient.Entities;
using ?System.Runtime.Serialization.Json;
using ?System.Data;
using ?System.Drawing;
using ?MBClient.Class;
namespace ?MBClient.API
{
???? internal ? class ?ReadDataBySinaAPI
????{
???????? internal ?ReadDataBySinaAPI()?{?}
???????? /// ? <summary>
???????? /// ?根據(jù)用戶登錄信息登錄并讀取用戶信息到DataSet
???????? /// ? </summary>
???????? /// ? <param?name="url"> API?URL?(XML?Format) http://api.t.sina.com.cn/account/verify_credentials.xml?source=AppKey </param>
???? /// ? <param?name="httpRequestMethod)"> HTTP請求方式：GET或POST </param>
???????? /// ? <returns></returns>
???????? internal ? static ?DataSet?ReadXMLDataToDataSet( string ?url,? string ?httpRequestMethod)
????????{
???????????? try
????????????{
????????????????WebResponse?wr? = ?BasicAuthorizationRequest(url,?httpRequestMethod).GetResponse();
????????????????DataSet?ds? = ? new ?DataSet();
????????????????Stream?receieveStream? = ?wr.GetResponseStream();
????????????????StreamReader?reader? = ? new ?StreamReader(receieveStream,?Encoding.UTF8);
????????????????ds.ReadXml(reader);
????????????????reader.Close();
????????????????receieveStream.Close();
????????????????wr.Close();
???????????????? return ?ds;
????????????}
???????????? catch ?(Exception?e)
????????????{
???????????????? return ? null ;
????????????}
????????}
???????? /// ? <summary>
???????? /// ?HTTP普通驗證(Basic?Authentication)方式
???????? /// ? </summary>
???????? /// ? <param?name="url"> API?URL </param>
???????? /// ? <param?name="httpRequestMethod)"> HTTP請求方式：GET或POST </param>
???????? /// ? <returns></returns>
???????? private ? static ?WebRequest?BasicAuthorizationRequest( string ?url,? string ?httpRequestMethod)
????????{
????????????CredentialCache?mycache? = ? new ?CredentialCache();
????????????mycache.Add( new ?Uri(url),? " Basic " ,? new ?NetworkCredential(UserInfo.UserName,?UserInfo.Password));
????????????WebRequest?myReq? = ?WebRequest.Create(url);
????????????myReq.Credentials? = ?mycache;
????????????myReq.Headers.Add( " Authorization " ,? " Basic? " ? + ?Convert.ToBase64String( new ?ASCIIEncoding().GetBytes(UserInfo.UserNamePassword)));
????????????myReq.Method? = ?httpRequestMethod;
???????????? return ?myReq;
????????}
????}
}
?
?
?我這里直接用DataSet讀取XML了，當然也可以將XML數(shù)據(jù)反序列化，后面會看到，我將返回的JSON格式的圍脖信息進行了反序列化。
（4）登錄窗體代碼

???????? void ?backWorker_ProgressChanged( object ?sender,?System.ComponentModel.ProgressChangedEventArgs?e)
????????{
???????????? // throw?new?NotImplementedException();
????????}

????????????}

????}
}

關于登錄窗體的代碼，說兩點：
（1）使用皮膚
在你的Windows系統(tǒng)盤搜索IrisSkin2.dll
找到后添加到工具箱，右擊工具箱——選擇項——選擇這個dll
然后將SkinEngine控件拖到窗體上，在代碼中按照如下方式寫：
this .skinEngine.SkinFile? = ? @" skin\msn.ssk " ;?
這個ssk文件我使用了網(wǎng)上的資源，你也可以到網(wǎng)上去搜，可以下載到有20種左右的皮膚，有了皮膚文件，要實現(xiàn)換膚功能就非常簡單了。你也可以使用皮膚工具生成皮膚，如：skin++。?
?
（2）使用BackgroundWorker異步加載 ：關于BackgroundWorker，MSDN說的很清楚了，這里不再贅述，http://msdn.microsoft.com/zh-cn/library/system.componentmodel.backgroundworker(v=vs.80).aspx。
?
2、獲取當前登錄用戶及其所關注用戶的最新微博消息，并分頁顯示，這兒是我代碼最多的地方，主要是由于所有顯示的控件都動態(tài)加載的緣故。
今天看到新浪圍脖API更新了（近一個周都沒看），之前是只能傳頁碼，默認每頁返回20條數(shù)據(jù)；現(xiàn)在是可以傳頁碼和返回數(shù)據(jù)的條數(shù)。
===》statuses/friends_timeline?獲取當前登錄用戶及其所關注用戶的最新微博消息 (別名: statuses/home_timeline)
?
這里在第一次加載和翻頁時也使用BackgroundWorker。具體代碼不貼出來了，代碼太長，后面提供下載，供參考。
?
具體實現(xiàn)簡單說一下：
根據(jù)調(diào)用接口返回的JSON數(shù)據(jù)格式化為泛型對象集合，然后遍歷集合在Panel中動態(tài)添加控件顯示數(shù)據(jù)，主要一點是要計算好控件的位置。

這里要注意的一點是iso-8859-1這種編碼方式不支持中文，所以，把圖片內(nèi)容和非圖片內(nèi)容分開處理了。

（3）驗證輸入字數(shù)不能超過140字符?

7、降低工作內(nèi)存?
?? ? ? ? /// ? <summary>???????? /// ?設置工作內(nèi)存，降低內(nèi)存占用
???????? /// ? </summary>
???????? /// ? <param?name="maxWorkingSet"> 內(nèi)存中允許的進程的最大工作集大小（以字節(jié)為單位） </param>
???????? public ? static ? void ?SetWorkingSet( int ?maxWorkingSet)
????????{
????????????System.Diagnostics.Process.GetCurrentProcess().MaxWorkingSet? = ?(IntPtr)maxWorkingSet;
????????}
?
HTTP請求方式，API中有說明，所以上面沒有一一指出。?
