Android之QQ授权登录获取用户信息

有时候我们开发的app须要方便用户简单登录。能够让用户使用自己的qq、微信、微博登录到我们自己开发的app。

今天就在这里总结一下怎样在自己的app中集成QQ授权登录获取用户信息的功能。

首先我们打开腾讯开发平台这个网页，点击---->移动应用---->创建应用，成功创建应用后。能够产生我们须要的App ID和App Key，例如以下图所看到的：

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvYmVhcl9odWFuZ3poZW4=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="737" height="488" alt="">

然后我们须要下载Android-SDK-vxxx。下载完后解压我们能够得到两个jar包，和一个样例代码。这两个jar包是我们须要导入到自己app中的，它们的名字是：mta-sdk-1.6.2.jar、open_sdk_r5043.jar。

非常重要的參考资料是站点上提供的API文档和解压之后的Sample样例代码。

先来看一下demo效果：

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvYmVhcl9odWFuZ3poZW4=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="240" height="400" alt=""> 
    

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvYmVhcl9odWFuZ3poZW4=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="240" height="400" alt="">

接着我们開始集成，在AndroidManifest文件里增加下面内容：

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.bear.qqlogin.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name="com.tencent.tauth.AuthActivity"
            android:launchMode="singleTask"
            android:noHistory="true" >
            <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="1104732758" />
            </intent-filter>
        </activity>
        <activity
            android:name="com.tencent.connect.common.AssistActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:theme="@android:style/Theme.Translucent.NoTitleBar" />
    </application>

在主程序里面实现登录和获取用户信息。主要起作用的语句：

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

userInfo = new UserInfo(MainActivity.this, mTencent.getQQToken()); //获取用户信息

userInfo.getUserInfo(userInfoListener);

总体代码例如以下：

import org.json.JSONObject;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;
import android.widget.Toast;

import com.tencent.connect.UserInfo;
import com.tencent.connect.common.Constants;
import com.tencent.tauth.IUiListener;
import com.tencent.tauth.Tencent;
import com.tencent.tauth.UiError;

/**
 *
 * 通过调用Tencent类的login函数发起登录/校验登录态。

*
 * 该API具有两个作用：
 * （1）假设开发人员没有调用mTencent实例的setOpenId、setAccessToken API，
 * 		则该API运行正常的登录操作；
 * （2）假设开发人员先调用mTencent实例的setOpenId、setAccessToken
 * 		API。则该API运行校验登录态的操作。假设登录态有效，则返回成功给应用，
 * 		假设登录态失效，则会自己主动进入登录流程，将最新的登录态数据返回给应用
