最近想搞写一个基于QQ微博的桌面应用，按照官方的介绍，我使用C#的SDK进行开发，但是发现这个SDK关于登陆的地方很粗糙，另外发现通过OAuth的方式登陆的话，需要用户去填写获取到的verifer字符串。研究了一下，发现C#里面可以通过一个Webbrowser来解决这个问题。基于这个机制，我写了一个登陆的辅助类。

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.Threading;namespace QQWeiboApi{    public partial class FrmTencentAuth : Form    {        private volatile bool is_run;        public FrmTencentAuth()        {            InitializeComponent();        }        public string GetOauthVerifier(IWin32Window win, string tokenKey, string callbackurl)        {            string url = "http://open.t.qq.com/cgi-bin/authorize?oauth_token=" + tokenKey;            is_run = true;            webBrowser1.Navigate(url);            this.Show(win);            while (is_run == true && (webBrowser1.Url == null || ! webBrowser1.Url.ToString().StartsWith(callbackurl)))            {                Application.DoEvents();            }            if (is_run == false)            {                return null;            }            url = webBrowser1.Url.ToString();            this.Close();            string sl = "oauth_verifier=";            return url.Substring(url.IndexOf(sl) + sl.Length);        }        private void FrmTencentAuth_FormClosing(object sender, FormClosingEventArgs e)        {            is_run = false;        }    }}

上面是验证form的一部分，下面的是处理登陆的代码：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using QWeiboSDK;using System.Collections.Specialized;using System.Reflection;namespace QQWeiboApi{    public class QWeiboLoginHelper    {        private string appKey = null;        private string appSecret = null;        private string accessKey = null;        private string accessSecret = null;        private string requestKey = null;        private string requestSecret = null;        private string verifier = null;        private string callbackurl = "http://www.smallbridge.co.cc";        public QWeiboLoginHelper(string appKey, string appSecret)        {            this.appKey = appKey;            this.appSecret = appSecret;        }        ///         /// 登陆        /// 
        /// 应用的key        /// 应用secret        public void Login()        {            GetRequestToken(appKey, appSecret);            GetUserAuth();            GetAccessToken();        }        public OauthKey AuthKey        {            get            {                if (appKey == null || appSecret == null || accessKey == null || accessSecret == null)                {                    return null;                }                return new OauthKey() { customKey = appKey, customSecret = appSecret, tokenKey = accessKey, tokenSecret = accessKey };            }        }        private void GetAccessToken()        {            string url = "https://open.t.qq.com/cgi-bin/access_token";            List
    
      parameters = new List
     
      ();            OauthKey oauthKey = new OauthKey();            oauthKey.customKey = appKey;            oauthKey.customSecret = appSecret;            oauthKey.tokenKey = requestKey;            oauthKey.tokenSecret = requestSecret;            oauthKey.verify = verifier;            try            {                QWeiboRequest request = new QWeiboRequest();                string result = request.SyncRequest(url, "GET", oauthKey, parameters, null);                NameValueCollection nvs = ParseKVPairs(result);                accessKey = nvs["oauth_token"];                accessSecret = nvs["oauth_token_secret"];                if (accessKey == null || accessSecret == null)                {                    throw new Exception("get null accessKey or accessSecret");                }            }            catch (Exception ex)            {                throw new Exception("get accessKey and accessSecret error", ex);            }        }        private void GetUserAuth()        {            FrmTencentAuth frmau = new FrmTencentAuth();            try            {                verifier = frmau.GetOauthVerifier(null, requestKey, callbackurl);                if (verifier == null)                {                    throw new Exception("get null user oauth verifier");                }            }            catch (Exception ex)            {                throw new Exception("get user oauth verifier error", ex);            }        }        private void GetRequestToken(string appKey, string appSecret)        {            string url = "https://open.t.qq.com/cgi-bin/request_token";            List
      
        parameters = new List
       
        ();            OauthKey oauthKey = new OauthKey();            oauthKey.customKey = appKey;            oauthKey.customSecret = appSecret;            oauthKey.callbackUrl = callbackurl;            try            {                QWeiboRequest request = new QWeiboRequest();                string result = request.SyncRequest(url, "GET", oauthKey, parameters, null);                NameValueCollection nvs = ParseKVPairs(result);                requestKey = nvs["oauth_token"];                requestSecret = nvs["oauth_token_secret"];                if (requestKey == null || requestSecret == null)                {                    throw new Exception("get null request key or secret");                }            }            catch (Exception ex)            {                throw new Exception("get request key and secret error", ex);            }        }        private NameValueCollection ParseKVPairs(string str)        {            NameValueCollection nvs = new NameValueCollection();            foreach (string kv in str.Split('&'))            {                string[] kvs = kv.Split('=');                if (kvs.Length == 2)                {                    nvs.Add(kvs[0], kvs[1]);                }            }            return nvs;        }    }}
