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;



        }
