QQ授權登入(Android SDK3.1)

SDK下載 (最新3.1):http://connect.qq.com/intro/login

1.自己創建應用
首先我們打開騰訊開發平臺這個網頁，點擊—->移動應用—->創建應用，成功創建應用後，可以產生我們需要的App ID和App Key，如下圖所示：

2.運行官方Demo(官方Demo比較全,可以根據自己需求使用,我們在這裏只分析登入的代碼)

下面是主要的登錄代碼,在Demo的MainActivity裏面

/** 
 *  
 * 通過調用Tencent類的login函數發起登錄/校驗登錄態。  
 *  
 * 該API具有兩個作用： 
 * （1）如果開發者沒有調用mTencent實例的setOpenId,setAccessToken API,則該API執行正常的登錄操作； 
 * （2）如果開發者先調用mTencent實例的setOpenId、setAccessToken 
 *      API，則該API執行校驗登錄態的操作。如果登錄態有效，則返回成功給應用， 
 *      如果登錄態失效，則會自動進入登錄流程，將最新的登錄態數據返回給應用

    }
}

在主程序裏面實現登錄和獲取用戶信息，主要起作用的語句：

mTencent.login(MainActivity.this, scope, loginListener); //登錄

userInfo = new UserInfo(MainActivity.this, mTencent.getQQToken()); //獲取用戶信息
userInfo.getUserInfo(userInfoListener);

3.配置AndroidManifest

在應用的AndroidManifest.xml增加配置的<application>節點下增加以下配置（注：不配置將會導致無法調用API）；
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application>
 <activity
       android:name="com.tencent.tauth.AuthActivity"
       android:noHistory="true"
       android:launchMode="singleTask" >
    <intent-filter>
           <action android:name="android.intent.action.VIEW" />
           <category android:name="android.intent.category.DEFAULT" />
           <category android:name="android.intent.category.BROWSABLE" />
           <data android:scheme="tencent你的AppId" />
    </intent-filter>
 </activity>
<application>



其中，如果你已經添加了"android.permission.INTERNET"和"android.permission.ACCESS_NETWORK_STATE"權限，則無需重複添加。
而"你的AppId"則要替換成具體應用的AppId，例如你的AppId是"222222"，則<data>標籤應該是這樣的：
<data android:scheme="tencent222222" />

4.初始化實例

@Override

public void onCreate(Bundle savedInstanceState){

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

// Tencent類是SDK的主要實現類，開發者可通過Tencent類訪問騰訊開放的OpenAPI。

// 其中APP_ID是分配給第三方應用的appid，類型爲String。

mTencent = Tencent.createInstance(APP_ID, this.getApplicationContext());
// 1.4版本:此處需新增參數，傳入應用程序的全局context，可通過activity的getApplicationContext方法獲取
// 初始化視圖
initViews();

}

5.登錄按鈕被點擊的代碼

    private void onClickLogin() {
        if (!mTencent.isSessionValid()) {
            mTencent.login(this, "all", loginListener);
            isServerSideLogin = false;
            Log.d("SDKQQAgentPref", "FirstLaunch_SDK:" + SystemClock.elapsedRealtime());
        } else {
            if (isServerSideLogin) { // Server-Side 模式的登陸, 先退出，再進行SSO登陸
                mTencent.logout(this);
                mTencent.login(this, "all", loginListener);
                isServerSideLogin = false;
                Log.d("SDKQQAgentPref", "FirstLaunch_SDK:" + SystemClock.elapsedRealtime());
                return;
            }
            mTencent.logout(this);
            updateUserInfo();
            updateLoginButton();
        }
    }

6.實現回調

//這個是登錄時傳遞進去的接口
IUiListener loginListener = new BaseUiListener() {
        @Override
        protected void doComplete(JSONObject values) {
            Log.d("SDKQQAgentPref", "AuthorSwitch_SDK:" + SystemClock.elapsedRealtime());
            //去獲取Token與OpenId
            initOpenidAndToken(values);
        }
    };

--------------------華麗的分割線--------------------------------
    private class BaseUiListener implements IUiListener {
        @Override
        public void onComplete(Object response) {
            if (null == response) {
                Util.showResultDialog(MainActivity.this, "返回爲空", "登錄失敗");
                return;
            }
            JSONObject jsonResponse = (JSONObject) response;
            if (null != jsonResponse && jsonResponse.length() == 0) {
                Util.showResultDialog(MainActivity.this, "返回爲空", "登錄失敗");
                return;
            }
            Util.showResultDialog(MainActivity.this, response.toString(), "登錄成功");
            // 有獎分享處理
            handlePrizeShare();
            doComplete((JSONObject)response);
        }

        protected void doComplete(JSONObject values) {

        }

        @Override
        public void onError(UiError e) {
            Util.toastMessage(MainActivity.this, "onError: " + e.errorDetail);
            Util.dismissDialog();
        }

        @Override
        public void onCancel() {
            Util.toastMessage(MainActivity.this, "onCancel: ");
            Util.dismissDialog();
            if (isServerSideLogin) {
                isServerSideLogin = false;
            }
        }
    }

--------------------華麗的分割線--------------------------------
//去拿到ACCESS_TOKEN與PARAM_OPEN_ID與EXPIRES_IN(有效時間)
    public static void initOpenidAndToken(JSONObject jsonObject) {
        try {
            String token = jsonObject.getString(Constants.PARAM_ACCESS_TOKEN);
            String expires = jsonObject.getString(Constants.PARAM_EXPIRES_IN);
            String openId = jsonObject.getString(Constants.PARAM_OPEN_ID);

            System.out.println("token"+token+"-------------"+openId);
            if (!TextUtils.isEmpty(token) && !TextUtils.isEmpty(expires)
                    && !TextUtils.isEmpty(openId)) {
                mTencent.setAccessToken(token, expires);
                mTencent.setOpenId(openId);
            }
        } catch(Exception e) {
        }
    }

7.使用access_token和openid

應用在每次登錄之後，都會獲取到openid、access_token和expires_in，在調用SDK提供的接口時，後臺會根據這三個參數來驗證請求的合法性。
（1）如果應用已經走過登錄流程，調用應用分享、邀請等接口，是不需要再將這三個參數傳入到請求參數中去的，這是因爲在登錄成功後，SDK會自動將這幾個參數保存在SDK的上下文中，在發送請求時，會自動爲請求加上這些參數。
（2）如果應用不希望每次都走登錄流程來使用SDK的功能，可以通過以下步驟來實現：
Step1：在首次登錄成功後，將返回的openid、access_token、expires_in三個參數保存在本地（比如保存在sharedPreferrence）。其中expires_in參數在存儲前需進行如下計算：
1.System.currentTimeMillis() + Long.parseLong(expires_in) * 1000;
這樣得出的就是token的失效日期。
Step2：在用戶下次進入應用，發起應用分享等SDK調用之前，首先創建Tencent實例，然後取出之前保存的openid、access_token、expires_in（前面計算出來的值）的值。

Step3：調用Tencent類的setOpenId和setAccessToken方法。其中setOpenId的參數傳入上一步取出的openid，setAccessToken的第一個參數傳入上一步取出的access_token，第二個參數傳入（上一步保存的token失效日期-當前系統時間）/1000。這裏計算出的結果是當前保存的token的有效時間，如果結果小於或等於0，表示token已經過期，應該提示用戶重新走登錄流程。
免登錄流程調用SDK接口的示例代碼如下（省去了獲取存儲的變量的過程）：
String openid = "1234567896ASDFGHJKLLIUYT";

String access_token = "2C0884DC4B930010D852D8D504FC9F4D";

String expires_in = "7776000"; // 實際值需要通過上面介紹的方法來計算

mTencent = Tencent.createInstance(APP_ID);

mTencent.setOpenId(openid);

mTencent.setAccessToken(access_token, expires_in);

8.混淆

-keep class com.tencent.open.TDialog$*

-keep class com.tencent.open.TDialog$* {*;}

-keep class com.tencent.open.PKDialog

-keep class com.tencent.open.PKDialog {*;}

-keep class com.tencent.open.PKDialog$*

-keep class com.tencent.open.PKDialog$* {*;}
