java微信扫码二维码 公众号发放红包
最新研究微信红包接口的问题真是困扰了我好久，因为微信的api 实在是太坑爹了 ，如何没有大量的测试是行不通的，我是拼凑的所有人的集合才弄明白，接下来跟大家分享一下java 结合jsp ，两个服务器如何实现 微信扫码二维码 然后公众号发放红包的例子。
1.准备工作先不说了（比如验证回调函数服务器域名啊、程序必须部署在80端口等等，开通微信支付等功能，这个微信api 说的很清晰），需要两个程序 ，一个作为微信接口的回掉函数程序用来获取 code(简称服务器A),另一个作为调取发送红包的程序（简称服务器B）。（java 端jar包就不写了直接写方法，有需要加我QQ379378920）
2.首先在A服务器上部署back.html页面 ，然后用生成二维码工具将此页面路径生成二维码，页面自动授权跳转到回第二个页面 getback.html
1 <!doctype html> 2 <html> 3 <head> 4 <meta http-equiv="content-type" content="txt/html; charset=utf-8"/> 5 6 <script type="text/javascript" src="jquery-1.8.3.js"></script> 7 <script type="text/javascript"> 8 $(document).ready(function () { 9 10 window.location.href ="https://open.weixin.qq.com/connect/oauth2/authorize?appid=微信公众号的appid&redirect_uri=回调函数页面路劲(我的是getback.html)&response_type=code&scope=snsapi_userinfo&state=STATE&connect_redirect=1#wechat_redirect" 11 12 }); 13 14 </script> 15 <style> 16 17 </style> 18 </head> 19 <body> 20 </body> 21 </html>
接下来是 getback.html 代码
<!doctype html> <html> <head> <meta http-equiv="content-type" content="txt/html; charset=utf-8"/> <script type="text/javascript" src="jquery-1.8.3.js"></script> <script type="text/javascript"> $(document).ready(function () { var code = getQueryString('code'); if (code != null) { window.location.href="B服务器路径的controller方法上?code="+code; } }); function getQueryString(name) { var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i"); var r = window.location.search.substr(1).match(reg); if (r != null) return unescape(r[2]); return null; } </script> <style> </style> </head> <body> </body> </html>
这个页面难点在于获取code，终于要说的微信最坑的地方了 就是获取的code 是在回调路径中隐藏的，api根本就没有写，我是通过截取的方法获取路径发送给B服务器的。
3.controller 我就不写了，我就写通过取回来的code如何获取openid的方法吧 java端个
public String getOpenId(String code) { String openid = ""; String uri="https://api.weixin.qq.com/sns/oauth2/access_token"; String requestEntity = "appid=" + 你的appid + "&secret=" + 你的秘钥 + "&code=" + code + "&grant_type=" + 你的grant_type; HttpUriRequest httpUriRequest = RequestBuilder.post() .setUri(uri) .setHeader("Content-Type", "application/x-www-form-urlencoded") .addParameter("_type", "json") .setEntity(new StringEntity(requestEntity, Charset.forName("utf-8"))) .build(); HttpResponse httpResponse = LocalHttpClient.execute(httpUriRequest); try { String result = EntityUtils.toString(httpResponse.getEntity()); JSONObject jsonObject = JSONObject.fromObject(result); openid = jsonObject.getString("openid"); System.out.println(openid); } catch (IOException e) { e.printStackTrace(); } return openid; }；
获取到openid就离成功不远了。
4.通过openid发送红包（不要看我的返回值redenvelope具体需求具体分析）
1 public String sendRedEnvelopes(String openId,String id) throws Exception { 2 String redenvelope=""; 3 //具体参数查看具体实体类，实体类中的的参数参考微信的红包发放接口，这里你直接用map，进行设置参数也可以。。。 4 5 //转换成发送给为微信的参数的xml 6 SendRedPackBack sendRedPackBack=new SendRedPackBack(); 7 sendRedPackBack.setNonce_str(MoneyUtils.buildRandom()); 8 sendRedPackBack.setMch_billno(MoneyUtils.getOrderNo()); 9 sendRedPackBack.setMch_id(参数实体里有我就不举例子了); 10 sendRedPackBack.setWxappid(); 11 sendRedPackBack.setSend_name(); 12 sendRedPackBack.setRe_openid(openId); 13 sendRedPackBack.setTotal_amount(); 14 sendRedPackBack.setTotal_num(); 15 sendRedPackBack.setWishing(); 16 sendRedPackBack.setClient_ip(); 17 sendRedPackBack.setAct_name(); 18 //将实体类转换为url形式 19 String urlParamsByMap = Tool.getUrlParamsByMap(Tool.toMap(sendRedPackBack)); 20 //拼接我们再前期准备好的API密钥，前期准备第5条 21 urlParamsByMap += "&key="+证书秘钥; 22 //进行签名，需要说明的是，如果内容包含中文的话，要使用utf-8进行md5签名，不然会签名错误 23 String sign = Tool.parseStrToMd5L32(urlParamsByMap).toUpperCase(); 24 sendRedPackBack.setSign(sign); 25 //微信要求按照参数名ASCII字典序排序，这里巧用treeMap进行字典排序 26 TreeMap treeMap = new TreeMap(Tool.toMap(sendRedPackBack)); 27 //然后转换成xml格式 28 String soapRequestData = Tool.getSoapRequestData(treeMap); 29 //发起请求前准备 30 RequestBody body = RequestBody.create(MediaType.parse("text/xml;charset=UTF-8"), soapRequestData); 31 Request request = new Request.Builder() 32 .url("https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack") 33 .post(body) 34 .build(); 35 //为http请求设置证书 36 SSLSocketFactory socketFactory = getSSL().getSocketFactory(); 37 X509TrustManager x509TrustManager = Platform.get().trustManager(socketFactory); 38 OkHttpClient okHttpClient = new OkHttpClient.Builder().sslSocketFactory(socketFactory, x509TrustManager).build(); 39 //得到输出内容 40 Response response = okHttpClient.newCall(request).execute(); 41 String content = response.body().string(); 42 System.out.println(content); 43 //解析返回数据 44 RedDevelop redDevelop= xmlBean(content,id); 45 if(redDevelop.getReturnCode().equals("SUCCESS")){ 46 if(redDevelop.getResultCode().equals("SUCCESS")){ 47 redenvelope= String.valueOf(redDevelop.getTotalAmount()/100); 48 //保存红包已经被领取 49 newUseRegisterService.setRedPack(id); 50 }else { 51 redenvelope="fail";//接口调取成功但是获取openid失败 52 } 53 }else { 54 redenvelope="fail";//接口调取失败 55 } 56 return redenvelope; 57 } 58 59 public SSLContext getSSL() throws KeyStoreException, IOException, CertificateException, NoSuchAlgorithmException, UnrecoverableKeyException, KeyManagementException { 60 61 KeyStore keyStore = KeyStore.getInstance("PKCS12"); 62 String mchId=你的微信商户id; 63 //证书位置自己定义 64 FileInputStream instream = new FileInputStream(new File(证书路径)); 65 try { 66 keyStore.load(instream, mchId.toCharArray()); 67 } finally { 68 instream.close(); 69 } 70 SSLContext sslcontext = SSLContexts.custom() 71 .loadKeyMaterial(keyStore, mchId.toCharArray()) 72 .build(); 73 return sslcontext; 74 } 75 76 //这部分是将调取成功后的xml返回值转成实体继续保存，实体就不提供了 77 public RedDevelop xmlBean(String content,String id){ 78 79 RedDevelop redDevelop=new RedDevelop(); 80 Document dom= null; 81 try { 82 dom = DocumentHelper.parseText(content); 83 } catch (DocumentException e) { 84 e.printStackTrace(); 85 } 86 Element root=dom.getRootElement(); 87 String returnCode=root.element("return_code").getText(); 88 String returnMsg=root.element("return_msg").getText(); 89 String resultCode=root.element("result_code").getText(); 90 String errCode=root.element("err_code").getText(); 91 String errCodeDes=root.element("err_code_des").getText(); 92 String mchBillno=root.element("mch_billno").getText(); 93 String mchId=root.element("mch_id").getText(); 94 String wxappid=root.element("wxappid").getText(); 95 String reOpenid=root.element("re_openid").getText(); 96 String totalAmount=root.element("total_amount").getText(); 97 redDevelop.setReturnCode(returnCode); 98 redDevelop.setReturnMsg(returnMsg); 99 redDevelop.setResultCode(resultCode); 100 redDevelop.setErrCode(errCode); 101 redDevelop.setErrCodeDes(errCodeDes); 102 redDevelop.setMchBillno(mchBillno); 103 redDevelop.setMchId(mchId); 104 redDevelop.setWxappid(wxappid); 105 redDevelop.setReOpenid(reOpenid); 106 redDevelop.setTotalAmount(Integer.valueOf(totalAmount)); 107 redDevelop.setRegisterId(id); 108 redDevelopService.save(redDevelop); 109 return redDevelop; 110 }
