最近在做一个图片分享的APP，为增加用户入口，便于注册，先采用新浪微博作为第三方的入口。 我采用的注册流程如下：
- 微博的开发者管理平台登录注册过程在这里就不提了，各位看官请自行百度。
- 介绍WebView的方式进行认证注册
- 考虑到日后可能添加其他第三方入口，在登陆页面添加如下内容：
1 btnWeibo.setOnClickListener(new View.OnClickListener() {
2
3 @Override
4 public void onClick(View v) {
5 Intent intent = new Intent(LoginActivity.this,
6 SinaOAuthActivity.class);
7 startActivity(intent);
8 }
9 });
2. 载入认证页面，使用到的微博提供的url功能接口如下
1 public static String SINA_CONSUMER_KEY = "APP KEY"; 2 public static String SINA_CONSUMER_SECRET = "APP SECRET"; 3 public static String ACCESS_TOKEN = ""; 4 public static String UID =""; 5 public static String PREFERENCES_NAME = "PACKET NAME"; //可在AndroidManifest.xml中查看 6 //认证页面url 7 public static String SINA_OAUTH = "https://api.weibo.com/oauth2/authorize?client_id=" 8 + SINA_CONSUMER_KEY 9 + "&response_type=code&redirect_uri=http://www.sina.com" 10 + "&display=mobile"; 11 //获取ACCESS TOKEN 12 public static String SINA_ACCESS_TOKEN = "https://api.weibo.com/oauth2/access_token?client_id=" 13 + SINA_CONSUMER_KEY 14 + "&client_secret=" 15 + SINA_CONSUMER_SECRET 16 + "&grant_type=authorization_code&redirect_uri=http://www.sina.com&code="; 17 //根据UID获取用户详细信息 18 private static String SINA_DETAIL_INFORMATION = "https://api.weibo.com/2/users/show.json?source=" 19 + SINA_CONSUMER_KEY 20 + "&access_token=" 21 + ACCESS_TOKEN 22 + "&uid="+UID;
3. 认证Activity代码如下， 登陆并获取用户信息后，与客户端进行通信，验证该用户（微博用户）是否已在本服务器注册，若已注册，直接登陆；若未注册，跳转至设置密码页面。之后在本地添加用户登录信息，即可免填写用户名密码直接登录。
1 public class SinaOAuthMainActivity extends Activity {
2 public WebView webview;
3 String code = "";
4 String result ="";
5 Intent intent;
6 public WeiboUser user = new WeiboUser();
7 public SPreferenceInf spi = new SPreferenceInf();
8 public static final String WEIBO_USER = "com.cse.myperson.WEIBO_USER";
9 @Override
10 protected void onCreate(Bundle savedInstanceState) {
11 super.onCreate(savedInstanceState);
12 setContentView(R.layout.sina_oauth_webview);
13 webview = (WebView) this.findViewById(R.id.oauth_webview);
14 webview.getSettings().setJavaScriptEnabled(true);
15 webview.setFocusable(true);
16 webview.loadUrl(WeiboConstant.SINA_OAUTH);
17
18 webview.setWebViewClient(new WebViewClient() {
19 @Override
20 public void onPageFinished(WebView view, String url) {
21 new Thread(runnable).start();
22 Log.i("onPageFinished", url + "网页加载完毕");
23 super.onPageFinished(view, url);
24 }
25
26 @Override
27 public boolean shouldOverrideUrlLoading(WebView view, String url) {
28 Log.i("shouldOverrideUrlLoading", url);
29 webview.loadUrl(url);
30 return super.shouldOverrideUrlLoading(view, url);
31 }
32
33 // 加载页面
34 @Override
35 public void onPageStarted(WebView view, String url, Bitmap favicon) {
36 Log.e("onPageStarted", url + "开始加载界面");
37 if (url.startsWith("http://www.sina.com")) {
38 // 取消授权后的界面
39 view.cancelLongPress();
40 view.stopLoading();
41
42 // 获取Code
43 Uri uri = Uri.parse(url);
44 code = uri.getQueryParameter("code");
45 Log.e("code", WeiboConstant.SINA_ACCESS_TOKEN + code);
46
47 try {
48 Thread.sleep(1000);
49 } catch (InterruptedException e) {
50 // TODO Auto-generated catch block
51 e.printStackTrace();
52 }
53 if (result.startsWith("{\"access_token\":")) {
54 int i = result.indexOf(":");
55 int j = result.indexOf(",");
56 WeiboConstant.ACCESS_TOKEN = result.substring(i + 2,
57 j - 1);
58 int uidIndex = result.indexOf("uid");
59 int endIndex = result.length();
60 WeiboConstant.UID = result.substring(uidIndex+6,endIndex-2);
61
62 Log.e("ACCESS_TOKEN", WeiboConstant.ACCESS_TOKEN);
63 Log.e("UID", WeiboConstant.UID);
64 new Thread(runnable_USER).start();
65 finish();
66 }
67 }
68 super.onPageStarted(view, url, favicon);
69 }
70 });
71 }
72
73 //登陆请求
74 Runnable runnable = new Runnable(){
75
76 @Override
77 public void run() {
78 // TODO Auto-generated method stub
79 if (code != null) {
80 result = HttpsUtil.HttpsPost(
81 WeiboConstant.SINA_ACCESS_TOKEN + code, "");
82 Log.e("Https地址", WeiboConstant.SINA_ACCESS_TOKEN + code);
83 Log.e("登录请求结果", result);
84 }
85 }
86
87 };

93 @Override

106 Log.e("用户详细信息", result);
107 }
108 String result = CheckRegister.checkRegisterRequest(url, user.getLoginname());
109 String[] params;
110 params = result.split(";");
111 if(params[0].equals("existed")){
112 SharedPerferenceUtil.writeSP(SinaOAuthActivity.this,
113 user.getLoginname(), params[1]);
114 intent = new Intent(SinaOAuthActivity.this,
115 LoginActivity.class);
116 startActivity(intent);
117 finish();
118 }else if(params[0].equals("inexist")){
119 toSetPass();
120 Toast.makeText(SinaOAuthActivity.this, "认证成功",
121 Toast.LENGTH_LONG).show();
122 }
123
124 }
125
126 };
127
128 /**
129 * 跳转至密码设置页面

131 public void toSetPass(){
132 Log.e("from success!!!!!","loginname is "+user.getLoginname()
133 +"username is "+user.getUsername());
134 intent = new Intent(SinaOAuthActivity.this,
135 SetPasswordActivity.class);
136 Bundle mBundle = new Bundle();
137 mBundle.putSerializable(WEIBO_USER, user);
138 intent.setAction(WEIBO_USER);
139 intent.putExtras(mBundle);
140 startActivity(intent);
141 }
142
143 }
4. 这里有一个地方需注意，当采用WebView微博登陆后，每次登陆都会在本地保存Cookies登陆信息。这也是我在开发中遇到的一个难题，一个用户注册成功后，再次进入，直接提示认证成功。一开始认为是用SharedPreferences将登陆信息保存为xml文件了，但在/data相关路径下没有找到。之后转念一想，会不会存在数据库里了，最后在/databases路径下找到了webviewCookiesChromium.db这个文件，在cookies表中，看到了登陆信息。 认证成功后，调用这个方法即可：
1 public static void removeCookie(Context context) {
2 CookieSyncManager.createInstance(context);
3 CookieManager cookieManager = CookieManager.getInstance();
4 cookieManager.removeAllCookie();
5 CookieSyncManager.getInstance().sync();
6 }
也许我采用了一种比较笨的方法，把Cookie的表都清空了，各位看客有好方法的话，请赐教哈。
5. 基本的流程是这样，设置密码，登陆等可自己替换。
