Android新浪微博-项目整理总结二[使用WebView获取OAuth验证码]

本文介绍了如何在Android应用中整合新浪微博的OAuth授权流程，包括获取request token、通过WebView进行用户授权，以及如何从WebView中捕获验证码oauth_verifier。在用户授权后，保存access token和Access token secret，完成授权过程。

0.1获取request token,得到授权url,put给只含有WebView的Activity来处理

requestToken = weibo.getOAuthRequestToken(OAuthConstant.CALLBACK_URL);
                    OAuthConstant.getInstance().setRequestToken(requestToken);
                    String authenticationURL = requestToken.getAuthenticationURL();
                    String authorizationURL = requestToken.getAuthorizationURL();
                    Log.v(TAG , "authenticationURL="+authenticationURL);
                    Log.v(TAG, "authorizationURL="+authorizationURL);
                    
                    Intent intent = new Intent(MainActivity.this,AuthorizationAct.class);
                    intent.putExtra("webViewUrl", authenticationURL);
                    startActivity(intent);

0.2 用户登陆授权,获取access token,从WebView中截获验证码oauth_verifier
