[操作系统]cocos2dx工程中接入支付宝sdk


1. 首先去支付宝官网下载开发者文档

2. 然后按着开发者文档将支付宝的sdk导入到你的工程中,并关联到工程中,步骤入下图:

(1)将从支付宝官方网站获得的支付宝的sdk的jar包拷贝到工程中的libs目录下,如图

(2)右键工程选择Properties,弹出如下窗口,首先选择1,其次选中2,最后点击3将拷到工程中的三个支付宝的jar包一一关联到工程中

3.  最后修改工程的AndroidManifest.

新权限:

  <uses-permission android:name="android.permission.INTERNET" />  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />  <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />  <uses-permission android:name="android.permission.READ_PHONE_STATE" />  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />  

支付宝的Activity:

 <!-- alipay sdk begin -->    <activity      android:name="com.alipay.sdk.app.H5PayActivity"      android:configChanges="orientation|keyboardHidden|navigation"      android:exported="false"      android:screenOrientation="behind"      android:windowSoftInputMode="adjustResize|stateHidden" >    </activity><!-- alipay sdk end -->

到此为止支付宝sdk导入工程的工作算是完成了,接下来就是使用sdk完成付费了。

虽然破坏了java的封装性,但是为了方便起见我还是将支付宝的使用写到了一个java文件里了,我把使用放到了工程自带的HelloCpp.java文件中了,代码如/****************************************************************************Copyright (c) 2010-2012 cocos2d-x.orghttp://www.cocos2d-x.org

还有支付宝封装好的几个java文件,我把它们跟HelloCpp.java文件放到了同一个包中,它们分别是Base64.java,PayResult.java,SignUtils.java,源码如下:

至此cocos2dx工程中接入支付宝的工作完成!
