java现金红包_微信现金红包接口demo(java)

[ 最近的机器内存又爆满了，出了新增机器内存外，还应该好好review一下我们的代码，有很多代码编写过于随意化，这些不好的习惯或对程序语言的不了解是应该好好打压打压了

话不多说直接上餐

主类

package com.yuwei.redpack.main;

import java.text.SimpleDateFormat;

import java.util.Date;

import java.util.Random;

import com.yuwei.redpack.sign.Signature;

import com.yuwei.redpack.util.Configure;

import com.yuwei.redpack.util.RequestUtil;

public class CopyOfMain {

public static void main(String[] args) throws Exception{

initSDKConfiguration("","","","","");

RedpackBean bean = new RedpackBean();

bean.setNonce_str(RequestUtil.getRandomStringByLength(32));

bean.setMch_billno("10位商户号"+new SimpleDateFormat("yyyyMMddHHmmssSSS").format(new Date())+new Random().nextInt(10));

bean.setMch_id("商户号");

bean.setWxappid("微信appid");

bean.setSend_name("商户名称");

bean.setRe_openid("接收用户openid");

bean.setTotal_amount(111);//金额分

bean.setTotal_num(1);//发送人数

bean.setWishing("红包祝福语");

bean.setClient_ip("活动名称");

bean.setAct_name("java");

bean.setRemark("备注");

bean.setSign(Signature.getSign(bean));

HttpsRequest https = new HttpsRequest();

String rets = https.sendPost("https://api.mch./mmpaymkttransfers/sendredpack", bean);

System.out.println(rets);

}

/**

private static void initSDKConfiguration(String key, String mchID, String wxappid, String certLocalPath, String certPassword){

Configure.setKey(key);

Configure.setMchID(mchID);

Configure.setWxappid(wxappid);

Configure.setCertLocalPath(certLocalPath);

Configure.setCertPassword(certPassword);

}

}

请求类

[1、接口文档https://pay./wiki/doc/api/cash_coupon.phpchapter=13_52、证书下载及证书安装首先，商户调用微信红包接口时，服务器会进行证书验证，所以要在

package com.yuwei.redpack.main;

public class RedpackBean {

private String nonce_str;

private String sign;

private String mch_billno;

private String mch_id;

private String wxappid;

private String send_name;

private String re_openid;

private int total_amount;

private int total_num;

private String wishing;

private String client_ip;

private String act_name;

private String remark;

public String getNonce_str() {

return nonce_str;

}

public void setNonce_str(String nonceStr) {

nonce_str = nonceStr;

}

public String getSign() {

return sign;

}

public void setSign(String sign) {

this.sign = sign;

}

public String getMch_billno() {

return mch_billno;

}

public void setMch_billno(String mchBillno) {

mch_billno = mchBillno;

}

public String getMch_id() {

return mch_id;

}

public void setMch_id(String mchId) {

mch_id = mchId;

}

public String getWxappid() {

return wxappid;

}

public void setWxappid(String wxappid) {

this.wxappid = wxappid;

}

public String getSend_name() {

return send_name;

}

public void setSend_name(String sendName) {

send_name = sendName;

}

public String getRe_openid() {

return re_openid;

}

public void setRe_openid(String reOpenid) {

re_openid = reOpenid;

}

public int getTotal_amount() {

return total_amount;

}

public void setTotal_amount(int totalAmount) {

total_amount = totalAmount;

}

public int getTotal_num() {

return total_num;

}

public void setTotal_num(int totalNum) {

total_num = totalNum;

}

public String getWishing() {

return wishing;

}

public void setWishing(String wishing) {

this.wishing = wishing;

}

public String getClient_ip() {

return client_ip;

}

public void setClient_ip(String clientIp) {

client_ip = clientIp;

}

public String getAct_name() {

return act_name;

}

public void setAct_name(String actName) {

act_name = actName;

}

public String getRemark() {

return remark;

}

public void setRemark(String remark) {

this.remark = remark;

}

}

知道各位对sign比较头痛，我上方法

public static String getSign(Object o) throws IllegalAccessException {

ArrayList list = new ArrayList();

Class cls = o.getClass();

Field[] fields = cls.getDeclaredFields();

for (Field f : fields) {

f.setAccessible(true);

if (f.get(o) != null && f.get(o) != "") {

list.add(f.getName() + "=" + f.get(o) + "&");

}

}

int size = list.size();

String [] arrayToSort = list.toArray(new String[size]);

Arrays.sort(arrayToSort, String.CASE_INSENSITIVE_ORDER);

StringBuilder sb = new StringBuilder();

for(int i = 0; i < size; i ++) {

sb.append(arrayToSort[i]);

}

String result = sb.toString();

result += "key=" + Configure.getKey();

result = MD5.MD5Encode(result).toUpperCase();

return result;

}用java反射的，适合所有class

祝各位成功！
