首先是获取新浪微博的OAuth授权(WebViewActivity.java)：

package haiyang.project.iweibo.ui;import haiyang.project.iweibo.R;import haiyang.project.iweibo.util.AuthUtil;import haiyang.project.iweibo.util.JavascriptInterface;import android.app.Activity;import android.app.ProgressDialog;import android.content.Intent;import android.os.Bundle;import android.os.Handler;import android.webkit.WebChromeClient;import android.webkit.WebView;import android.webkit.WebViewClient;import android.widget.Toast;/* * 新浪微博OAuth授权页面 */public class WebViewActivity extends Activity{private WebView webView;private ProgressDialog progressDialog;private static final int CLOSE_DLG=1;private Handler handler;String url=null;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);this.setContentView(R.layout.webview);url=AuthUtil.getAuthorizationURL();if(url==null){Toast.makeText(this, R.string.auth_url_empty, 3000).show();return;}init();load(url,webView);handler=new Handler(){public void handleMessage(android.os.Message msg) {if(msg.what==CLOSE_DLG){progressDialog.dismiss();}};};}public void init(){if(progressDialog==null){progressDialog=new ProgressDialog(this);}progressDialog.setMessage("正在加载");progressDialog.show();webView=(WebView) this.findViewById(R.id.wv_oauth); webView.getSettings().setJavaScriptEnabled(true);webView.addJavascriptInterface(new JavascriptInterface(), "Methods");webView.setWebViewClient(new WebViewClient(){@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {load(url,webView);return true;}@Overridepublic void onPageFinished(WebView view, String url) {if(url.equals("http://api.t.sina.com.cn/oauth/authorize")){String load="javascript:window.Methods.getPin('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>')";view.loadUrl(load);Intent intent=new Intent(WebViewActivity.this,AccessTokenActivity.class);startActivity(intent);}super.onPageFinished(view, url);}});webView.setWebChromeClient(new WebChromeClient(){public void onProgressChanged(WebView view, int newProgress) {if(newProgress==100){handler.sendEmptyMessage(CLOSE_DLG);}super.onProgressChanged(view, newProgress);}});}public void load(final String url,final WebView view){if(url==null||"".equals(url)){return;}new Thread(){public void run() {view.loadUrl(url);}}.start();}}

获取授权URL(AuthUtil.java)

package haiyang.project.iweibo.util;import weibo4android.Weibo;import weibo4android.WeiboException;import weibo4android.http.AccessToken;import weibo4android.http.RequestToken;public class AuthUtil {private static Weibo weibo;private static RequestToken requestToken;static{System.setProperty("weibo4j.oauth.consumerKey", Weibo.CONSUMER_KEY);System.setProperty("weibo4j.oauth.consumerSecret", Weibo.CONSUMER_SECRET);weibo=new Weibo();}/** * 获取授权URL * @return */public static String getAuthorizationURL(){try {requestToken=weibo.getOAuthRequestToken();return requestToken.getAuthorizationURL();} catch (WeiboException e) {// TODO Auto-generated catch blocke.printStackTrace();}return null;}public static void getAccessToken(String pin){try {AccessToken accessToken=requestToken.getAccessToken(pin);System.out.println("Access token: "+ accessToken.getToken());System.out.println("Access token secret: "+ accessToken.getTokenSecret());System.out.println("userID: "+accessToken.getUserId());} catch (WeiboException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

获取PIN值

package haiyang.project.iweibo.util;import java.util.regex.Matcher;import java.util.regex.Pattern;/** * 获取PIN值 * @author Administrator * */public class JavascriptInterface {//授权码public static String PIN=null;public void getPin(String html){String pin=null;String reg="[0-9]{6}";Pattern pattern=Pattern.compile(reg);Matcher matcher=pattern.matcher(html);if(matcher.find()){//find each match in turnpin=matcher.group(0);//Access a submatch group}PIN=pin;}}

获取AccessToken

package haiyang.project.iweibo.ui;import haiyang.project.iweibo.util.AuthUtil;import haiyang.project.iweibo.util.JavascriptInterface;import android.app.Activity;import android.os.Bundle;public class AccessTokenActivity extends Activity{protected void onCreate(Bundle savedInstanceState) {String pin=JavascriptInterface.PIN;AuthUtil.getAccessToken(pin);super.onCreate(savedInstanceState);}}
