@与server交互通信调用,android端仅仅需获取server參数填入微信.
==========================================
1,开启
2,结果(支付和微信分享的Activity要安装api文档上说明的放到指定的包名内),支付结果最好要通知一下server.
3,演示样例
公布使用的签名正确的话取消和成功都能正确通知.
==========================================
@自己測试调用:Android自己请求微信server,一般不会这样搞,仅仅是练习须要这样...
1,导入微信的libs包libammsdk.jar;
2,測试时使用weixinDemo中的debug_keystore;
3,须要注意应用要通过审核,而且几个Key值正确,一下为微信支付Demo中的值:
//微信公众平台id;private String app_wx_appid=WxConstants.app_wx_appid;//微信开放平台和商户约定的密钥private String app_wx_secret_key="db426a9829e4b49a0dcac7b4162da6b6";//微信公众平台商户模块和商户约定的密钥private String app_wx_parent_key="8934e7d15453e97507ef794cf7b0519d";//微信公众平台商户模块和商户约定的支付密钥private String app_wx_pay_key="L8LrMqqeGRxST5reouB0K66CaYAWpqhAVsq7ggKkxHCOastWksvuX1uvmvQclxaHoYd3ElNBrNO2DHnnzgfVG9Qs473M3DTOZug5er46FhuGofumV8H2FVR9qkjSlC5K";// 商家向財付通申请的商家id */private String app_tx_parent_key = "1900000109";
==========================================
依据微信支付Demo,微信支付分为三步:
第一步,获取accessToken,accessToken值第二步要用;
private class GetAccessTokenTask extends AsyncTask<Void, Void, WxGetAccessTokenResult> {@Overrideprotected WxGetAccessTokenResult doInBackground(Void... params) {WxGetAccessTokenResult result = getAccessToken();return result;}@Overrideprotected void onPostExecute(WxGetAccessTokenResult result) {if (result.localRetCode == WxLocalRetCode.ERR_OK) {GetPrepayIdTask getPrepayId = new GetPrepayIdTask();getPrepayId.execute(result);}}}解析server响应
private WxGetAccessTokenResult getAccessToken() {WxGetAccessTokenResult result = new WxGetAccessTokenResult();String url = String.format(api_get_access_token, "client_credential",app_wx_appid, app_wx_secret_key);byte[] buf = WeixinUtil.httpGet(url);if (buf == null || buf.length == 0) {result.localRetCode = WxLocalRetCode.ERR_HTTP;return result;}String content = new String(buf);result.parseFrom(content);return result;}第二步,依据第一步的accesstoken值,将 组装的商品參数Post给微信server
private class GetPrepayIdTask extends AsyncTask<WxGetAccessTokenResult, Void, WxGetPrepayIdResult> {@Overrideprotected WxGetPrepayIdResult doInBackground(WxGetAccessTokenResult... params) {WxGetPrepayIdResult result = getPrepayId(params[0]);return result;}@Overrideprotected void onPostExecute(WxGetPrepayIdResult result) {if (result.localRetCode == WxLocalRetCode.ERR_OK) {sendPayReq(result);}}}组装參数
private WxGetPrepayIdResult getPrepayId(WxGetAccessTokenResult accessTokenResult) {String url = String.format(api_get_preorder_id,accessTokenResult.accessToken);String entity = appSign.getWxPrepayAppSign();WxGetPrepayIdResult result = new WxGetPrepayIdResult();byte[] buf = WeixinUtil.httpPost(url, entity);if (buf == null || buf.length == 0) {result.localRetCode = WxLocalRetCode.ERR_HTTP;return result;}String content = new String(buf);result.parseFrom(content);return result;}Post给server
<span style="white-space:pre"></span>private void sendPayReq(WxGetPrepayIdResult result) {PayReq req = new PayReq();req.appId = app_wx_appid;req.partnerId = app_tx_parent_key;req.prepayId = result.prepayId;req.nonceStr = appSign.getNoncestr();req.timeStamp = appSign.getTimestamp();req.packageValue = "Sign=" + appSign.getPackageSign();List<NameValuePair> signParams = new LinkedList<NameValuePair>();signParams.add(new BasicNameValuePair("appid", req.appId));signParams.add(new BasicNameValuePair("appkey", app_wx_pay_key));signParams.add(new BasicNameValuePair("noncestr", req.nonceStr));signParams.add(new BasicNameValuePair("package", req.packageValue));signParams.add(new BasicNameValuePair("partnerid", req.partnerId));signParams.add(new BasicNameValuePair("prepayid", req.prepayId));signParams.add(new BasicNameValuePair("timestamp", req.timeStamp));req.sign = WeixinUtil.genSign(signParams);wxRequest.sendReq(req);}第三步:在项目下新建一个包wxapi,建立一个类名为WXPayEntryActivity作为接受微信的支付结果,只是终于结果以server的返回为准notify_url:
package net.sourceforge.simcpux.wxapi;public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler{<pre name="code" class="java"><span style="white-space:pre"></span>@Overridepublic void onResp(BaseResp resp) {Log.d(TAG, "onPayFinish, errCode = " + resp.errCode);if (resp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) {AlertDialog.Builder builder = new AlertDialog.Builder(this);builder.setTitle("支付结果");builder.setMessage("支付结果"+String.valueOf(resp.errCode));builder.show();}}} ==========================================
临时没想到其它想说的,先看个效果
1,包结构,须要注意的就是接收微信返回结果的那个类名;
2,组装数据,规则在文档中有说明
//package_ 字段生成方法//package生成方法://A)对全部传入參数依照字段名的ASCII 码从小到大排序(字典序)后,使用URL 键值对的格式(即key1=value1&key2=value2…)拼接成字符串string1;//B) 在string1 最后拼接上key=partnerKey 得到stringSignTemp 字符串。 并对 stringSignTemp进行md5 运算,再将得到的字符串全部字符转换为大写,得到sign值signValue。//C)对string1 中的全部键值对中的value 进行urlencode 转码,依照a 步骤又一次拼接成字符串。得到string2。对于js 前端程序。一定要使用函数encodeURIComponent 进行urlencode编码(注意!进行urlencode时要将空格转化为%20而不是+)。//D)将sign=signValue 拼接到string1 后面得到终于的package 字符串。
//app_signature生成方法://A)參与签名的字段包含:appid、appkey、noncestr、package、timestamp以及 traceid //B)对全部待签名參数依照字段名的ASCII 码从小到大排序(字典序)后,使用URL 键值对的格式(即key1=value1&key2=value2…)拼接成字符串string1。 注意:全部參数名均为小写字符//C)对string1 作签名算法,字段名和字段值都採用原始值。不进行URL 转义。详细签名算法为SHA1
