java微信

最近有弄服务号的现金红包和企业付款，和微信支付 弄完之后发现其实这些基本都差不多.

所有我这里就把微信企业付款记录一样

首先  还是先看一下文档  .php?chapter=14_2  点击打开链接

在文档中我们可以看到，企业付款需要调用的url和所有参数的说明，这里的话就需要自己去看去理解了。

如果要使用 现金红包和企业付款 要先去开通在产品中心里面 就要 点击进去开通就行了 ，顺便填写一下机器ip地址

之后我要提一下的是机器ip是外网ip，如果是在本地测试的就要注意一下  然后保持一致就行了 

这里的话还有个最主要的证书需要下载，我们可以下载到D盘cert目录下 D:/cert      这个证书的下载 只要登陆微信商户平台 API安全  就可以了 看自己是什么语言就下载什么证书，这里文档有说明 

一些微信的基本配置我都写在了 #weixin mp config

appID=xxxx
appsecret=xxxx
token=xxxx
#商户号
partnerId=xxx
#商户支付密钥
partnerKey=xxxx
#微信统一支付接口
payUrl=
#支付结果通知的回调地址
payCallBack= 域名/wechatPay/wechat_notify
queryOrderUrl=

前面的准备工作都ok 之后就是写代码了

建一个微信需要的企业付款参数 transfers 类 

public class Transfers {private String mch_appid;// 公众账号private String mchid;// 商户号private String nonce_str;// 随机字符串private String sign;// 签名private String partner_trade_no;// 商户订单号private String openid;// 用户openid//校验用户姓名选项  NO_CHECK：不校验真实姓名 private String check_name;private int amount;// 付款金额private String desc;// 企业付款描述信息private String spbill_create_ip;// 调用接口的机器Ip地址public String getMch_appid() {return mch_appid;}public void setMch_appid(String mch_appid) {h_appid = mch_appid;}public String getMchid() {return mchid;}public void setMchid(String mchid) {hid = mchid;}public String getNonce_str() {return nonce_str;}public void setNonce_str(String nonce_str) {_str = nonce_str;}public String getSign() {return sign;}public void setSign(String sign) {this.sign = sign;}public String getPartner_trade_no() {return partner_trade_no;}public void setPartner_trade_no(String partner_trade_no) {this.partner_trade_no = partner_trade_no;}public String getOpenid() {return openid;}public void setOpenid(String openid) {this.openid = openid;}public String getCheck_name() {return check_name;}public void setCheck_name(String check_name) {this.check_name = check_name;}public int getAmount() {return amount;}public void setAmount(int amount) {this.amount = amount;}public String getDesc() {return desc;}public void setDesc(String desc) {this.desc = desc;}public String getSpbill_create_ip() {return spbill_create_ip;}public void setSpbill_create_ip(String spbill_create_ip) {this.spbill_create_ip = spbill_create_ip;}}

之后就是给 这些参数赋值 

	@Autowiredprivate XMLUtil xmlUtil;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.math.BigDecimal;
import java.security.KeyStore;
import java.sql.Timestamp;
SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Random;
import java.util.UUID;import javax.ssl.SSLContext;import dec.digest.DigestUtils;
import org.apache.http.HttpEntity;
import org.apache.hods.CloseableHttpResponse;
import org.apache.hods.HttpPost;
import org.ssl.SSLConnectionSocketFactory;
import org.ity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContexts;
import org.apache.http.util.EntityUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

上面是导入的包 下面就是给参数配值了

private void redPackets(Integer withdrawId, String openId) throws Exception {int total=100;int amount = (int) (total*100);Transfers transfers=new Transfers();String nonce = UUID.randomUUID().toString().substring(0, 30);SimpleDateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");String time = df.format(new Date());Random ne=new Random();int guid&#Int(9999-1000+1)+1000;transfers.setMch_appid(APPID);// 自己的公众账号transfers.setMchid(partnerId);//自己的 商户号transfers.setNonce_str(nonce);// 随机字符串transfers.setOpenid(openId);// 用户openIdtransfers.setCheck_name("NO_CHECK");// 校验用户姓名选项transfers.setAmount(amount);// 付款金额transfers.setDesc("微信企业付款");// 企业付款描述信息transfers.setSpbill_create_ip("120.236.82.202");// 调用接口的机器Ip地址transfers.setPartner_trade_no(WxConfig.partnerId+time+guid);// 商户订单号String sign = createSendRedPackOrderSign(transfers);transfers.setSign(sign);// 签名xmlUtil.xstream().alias("xml", Class());String xml = xmlUtil.xstream().toXML(transfers);String sendEedPackUrl="";String response = ssl(sendEedPackUrl,xml);Map<String, String> responseMap = xmlUtil.parseXml(response);String return_msg = ("return_msg");System.out.println(return_msg);}

这里就是根据上面的内容生成签名 sign 这里文档有说明 这里要注意的是去，签名要按照 ASCII码从小到大排序（字典序）

public String createSendRedPackOrderSign(Transfers transfers){StringBuffer sign = new StringBuffer();sign.append("mch_appid=").Mch_appid());sign.append("&mchid=").Mchid());sign.append("&nonce_str=").Nonce_str());sign.append("&partner_trade_no=").Partner_trade_no());sign.append("&openid=").Openid());sign.append("&check_name=").Check_name());sign.append("&amount=").Amount());sign.append("&desc=").Desc());sign.append("&spbill_create_ip=").Spbill_create_ip());sign.append("&key=").append(WxConfig.partnerKey);return  DigestUtils.String()).toUpperCase();}

然后就是xmlutil类了 我是在网上大神博客找的

import java.io.ByteArrayInputStream;
import java.io.InputStream;

如何就是ssl方法 

private String ssl(String url,String data){StringBuffer message = new StringBuffer();try {KeyStore keyStore  = Instance("PKCS12");FileInputStream instream = new FileInputStream(new File("D:/cert/apiclient_cert.p12"));keyStore.load(instream, CharArray());// Trust own CA and all self-signed certsSSLContext sslcontext = SSLContexts.custom().loadKeyMaterial(keyStore, CharArray()).build();// Allow TLSv1 protocol onlySSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslcontext,new String[] { "TLSv1" },null,SSLConnectionSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER);CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();HttpPost httpost = new HttpPost(url);httpost.addHeader("Connection", "keep-alive");httpost.addHeader("Accept", "*/*");httpost.addHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");httpost.addHeader("Host", &#h.weixin.qq");httpost.addHeader("X-Requested-With", "XMLHttpRequest");httpost.addHeader("Cache-Control", "max-age=0");httpost.addHeader("User-Agent", "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0) ");httpost.setEntity(new StringEntity(data, "UTF-8"));//System.out.println("executing request" + RequestLine());CloseableHttpResponse response = ute(httpost);try {HttpEntity entity = Entity();//System.out.println("----------------------------------------");//System.out.StatusLine());if (entity != null) {//System.out.println("Response content length: " + ContentLength());BufferedReader bufferedReader = new BufferedReader(new Content(),"UTF-8"));String text;while ((text = adLine()) != null) {message.append(text);}}sume(entity);} catch (IOException e) {e.printStackTrace();} finally {response.close();}} catch (Exception e1) {e1.printStackTrace();} String();}

如果还有什么不懂的可以去看 这位大师的博客，我也是根据他的来写的 ，顺便说一下是java微信红包的！
