IWXAPI的使用，发布分享和支付

今天看代码，看到以前项目的微信支付功能，想做一下记录

首先是在application类里面定义

public static IWXAPI MSGAPI;





public static final String WX_APPID="xxxxxxxxxxxxxxxxxxx";//你的应用从官方网站申请到的合法appId

将该app注册到微信

        MSGAPI=WXAPIFactory.createWXAPI(applicationContext,WX_APPID,false);





        MSGAPI.registerApp(WX_APPID);

首先支付功能

        if(!ApplicationXpClient.MSGAPI.isWXAppInstalled()){





        Log.d("weixinPay","未安装微信");





        return;





        }





        if(!ApplicationXpClient.MSGAPI.isWXAppSupportAPI()){





        Log.d("weixinPay","版本不支持");





        return;





        }





        PayReq request=new PayReq();//weixinPayData是后台返回的类





        request.appId=ApplicationXpClient.WX_APPID;





        request.partnerId="1387300802";





        request.prepayId=weixinPayData.getPrepay_id();





        request.packageValue="Sign=WXPay";





        request.nonceStr=weixinPayData.getNonce_str();





        request.timeStamp=weixinPayData.getDateTime();





        request.sign=weixinPayData.getSign();





        ApplicationXpClient.MSGAPI.sendReq(request);

然后是分享功能

        int WX_THUMB_SIZE=120;





        if(!ApplicationXpClient.MSGAPI.isWXAppInstalled()){





        Log.d("weixinPay","未安装微信");





        return;





        }





        if(!ApplicationXpClient.MSGAPI.isWXAppSupportAPI()){





        Log.d("weixinPay","版本不支持");





        return;





        }





        //初始化一个WXWebpageObject对象，填写url





        WXWebpageObject webpage=new WXWebpageObject();





 





        webpage.webpageUrl="www.pooai.com";//这里用小普马桶官网做推广





 





        //用WXWebpageObject对象初始化一个WXMediaMessage对象，填写标题、描述





        WXMediaMessage msg=new WXMediaMessage(webpage);





        msg.title="小普未来科技";





        msg.description="一款来自未来的云健康智能马桶";





        Bitmap thumb=BitmapFactory.decodeResource(getResources(),R.drawable.xiaopu);





        Bitmap thumbBmp=Bitmap.createScaledBitmap(thumb,WX_THUMB_SIZE,WX_THUMB_SIZE,true);





        thumb.recycle();





        msg.thumbData=bmpToByteArray(thumbBmp,true);





 





        //构造一个Req





        SendMessageToWX.Req req=new SendMessageToWX.Req();





        req.transaction=String.valueOf(System.currentTimeMillis());





        req.message=msg;





        req.scene=SendMessageToWX.Req.WXSceneSession;//分享给朋友





        //req.scene = SendMessageToWX.Req.WXSceneTimeline;//分享到朋友圈





        ApplicationXpClient.MSGAPI.sendReq(req);





 





  public static byte[]bmpToByteArray(final Bitmap bmp,final boolean needRecycle){





        ByteArrayOutputStream output=new ByteArrayOutputStream();





        bmp.compress(CompressFormat.PNG,100,output);





        if(needRecycle){





        bmp.recycle();





        }





        byte[]result=output.toByteArray();





        try{





        output.close();





        }catch(Exception e){





        e.printStackTrace();





        }





        return result;





        }
