javaweb微信支付開發,掃碼+H5支付
阿新 • • 發佈:2019-01-05
公司專案框架是spring+struts2+mybatis。
最近,因公司專案需要用到微信支付,第一次接觸走了很多彎路,在看了很多大神的demo之後,終於搞定了。記住這不是微信公眾號支付,是PC端掃二維碼跟手機端H5點選支付按鈕的微信支付。
一、工具包
需要用到的工具包有生成二維碼的工具包。
這裡我用的是谷歌的ZXing包——core-3.2.1.jar,這個可以上百度去找,很容易下載。
首先是工具包(建個util包全裝起來),裡面引入的包都挺好找的
HttpUtil
訪問微信支付地址需要用到
package com.yc.weixinutil; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.OutputStreamWriter; import java.net.URL; import java.net.URLConnection; public class HttpUtil { //private static final Log logger = Logs.get(); private final static int CONNECT_TIMEOUT = 5000; // in milliseconds private final static String DEFAULT_ENCODING = "UTF-8"; public static String postData(String urlStr, String data){ return postData(urlStr, data, null); } public static String postData(String urlStr, String data, String contentType){ BufferedReader reader = null; try { URL url = new URL(urlStr); URLConnection conn = url.openConnection(); conn.setDoOutput(true); conn.setConnectTimeout(CONNECT_TIMEOUT); conn.setReadTimeout(CONNECT_TIMEOUT); if(contentType != null) conn.setRequestProperty("content-type", contentType); OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream(), DEFAULT_ENCODING); if(data == null) data = ""; writer.write(data); writer.flush(); writer.close(); reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), DEFAULT_ENCODING)); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line); sb.append("\r\n"); } return sb.toString(); } catch (IOException e) { //logger.error("Error connecting to " + urlStr + ": " + e.getMessage()); System.out.println("Error connecting to " + urlStr + ": " + e.getMessage()); } finally { try { if (reader != null) reader.close(); } catch (IOException e) { } } return null; } }
MatrixToImageWriter
這個是谷歌生成二維碼的類
package com.yc.weixinutil; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import java.io.OutputStream; import javax.imageio.ImageIO; import com.google.zxing.common.BitMatrix; public class MatrixToImageWriter { private static final int BLACK = 0xFF000000; private static final int WHITE = 0xFFFFFFFF; private MatrixToImageWriter() { } public static BufferedImage toBufferedImage(BitMatrix matrix) { int width = matrix.getWidth(); int height = matrix.getHeight(); BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); for (int x = 0; x < width; x++) { for (int y = 0; y < height; y++) { image.setRGB(x, y, matrix.get(x, y) ? BLACK : WHITE); } } return image; } public static void writeToFile(BitMatrix matrix, String format, File file) throws IOException { BufferedImage image = toBufferedImage(matrix); if (!ImageIO.write(image, format, file)) { throw new IOException("Could not write an image of format " + format + " to " + file); } } public static void writeToStream(BitMatrix matrix, String format, OutputStream stream) throws IOException { BufferedImage image = toBufferedImage(matrix); if (!ImageIO.write(image, format, stream)) { throw new IOException("Could not write an image of format " + format); } } }
MD5Util
千篇一律的MD5轉碼
package com.yc.weixinutil; import java.security.MessageDigest; public class MD5Util { private static String byteArrayToHexString(byte b[]) { StringBuffer resultSb = new StringBuffer(); for (int i = 0; i < b.length; i++) resultSb.append(byteToHexString(b[i])); return resultSb.toString(); } private static String byteToHexString(byte b) { int n = b; if (n < 0) n += 256; int d1 = n / 16; int d2 = n % 16; return hexDigits[d1] + hexDigits[d2]; } public static String MD5Encode(String origin, String charsetname) { String resultString = null; try { resultString = new String(origin); MessageDigest md = MessageDigest.getInstance("MD5"); if (charsetname == null || "".equals(charsetname)) resultString = byteArrayToHexString(md.digest(resultString .getBytes())); else resultString = byteArrayToHexString(md.digest(resultString .getBytes(charsetname))); } catch (Exception exception) { } return resultString; } private static final String hexDigits[] = { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "e", "f" }; }
PayToolUtil
生成微信簽名
package com.yc.weixinutil;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;
import java.util.SortedMap;
public class PayToolUtil {
/**
* 是否簽名正確,規則是:按引數名稱a-z排序,遇到空值的引數不參加簽名。
*
* @return boolean
*/
public static boolean isTenpaySign(String characterEncoding,
SortedMap<Object, Object> packageParams, String API_KEY) {
StringBuffer sb = new StringBuffer();
Set es = packageParams.entrySet();
Iterator it = es.iterator();
while (it.hasNext()) {
Map.Entry entry = (Map.Entry) it.next();
String k = (String) entry.getKey();
String v = (String) entry.getValue();
if (!"sign".equals(k) && null != v && !"".equals(v)) {
sb.append(k + "=" + v + "&");
}
}
sb.append("key=" + API_KEY);
// 算出摘要
String mysign = MD5Util.MD5Encode(sb.toString(), characterEncoding)
.toLowerCase();
String tenpaySign = ((String) packageParams.get("sign")).toLowerCase();
// System.out.println(tenpaySign + " " + mysign);
return tenpaySign.equals(mysign);
}
/**
* @author
* @date 2016-4-22
* @Description:sign簽名
* @param characterEncoding
* 編碼格式
* @param parameters
* 請求引數
* @return
*/
public static String createSign(String characterEncoding,
SortedMap<Object, Object> packageParams, String API_KEY) {
StringBuffer sb = new StringBuffer();
Set es = packageParams.entrySet();
Iterator it = es.iterator();
while (it.hasNext()) {
Map.Entry entry = (Map.Entry) it.next();
String k = (String) entry.getKey();
String v = (String) entry.getValue();
if (null != v && !"".equals(v) && !"sign".equals(k)
&& !"key".equals(k)) {
sb.append(k + "=" + v + "&");
}
}
sb.append("key=" + API_KEY);
String sign = MD5Util.MD5Encode(sb.toString(), characterEncoding)
.toUpperCase();
return sign;
}
/**
* @author
* @date 2016-4-22
* @Description:將請求引數轉換為xml格式的string
* @param parameters
* 請求引數
* @return
*/
public static String getRequestXml(SortedMap<Object, Object> parameters) {
StringBuffer sb = new StringBuffer();
sb.append("<xml>");
Set es = parameters.entrySet();
Iterator it = es.iterator();
while (it.hasNext()) {
Map.Entry entry = (Map.Entry) it.next();
String k = (String) entry.getKey();
String v = (String) entry.getValue();
if ("attach".equalsIgnoreCase(k) || "body".equalsIgnoreCase(k)
|| "sign".equalsIgnoreCase(k)) {
sb.append("<" + k + ">" + "<![CDATA[" + v + "]]></" + k + ">");
} else {
sb.append("<" + k + ">" + v + "</" + k + ">");
}
}
sb.append("</xml>");
return sb.toString();
}
/**
* 取出一個指定長度大小的隨機正整數.
*
* @param length
* int 設定所取出隨機數的長度。length小於11
* @return int 返回生成的隨機數。
*/
public static int buildRandom(int length) {
int num = 1;
double random = Math.random();
if (random < 0.1) {
random = random + 0.1;
}
for (int i = 0; i < length; i++) {
num = num * 10;
}
return (int) ((random * num));
}
/**
* 獲取當前時間 yyyyMMddHHmmss
*
* @return String
*/
public static String getCurrTime() {
Date now = new Date();
SimpleDateFormat outFormat = new SimpleDateFormat("yyyyMMddHHmmss");
String s = outFormat.format(now);
return s;
}
}
PayConfigUtil
微信支付需要用到的常量
package com.yc.weixinutil;
import java.net.InetAddress;
import java.net.UnknownHostException;
public class PayConfigUtil {
// 這個就是自己要保管好的私有Key了(切記只能放在自己的後臺程式碼裡,不能放在任何可能被看到原始碼的客戶端程式中)
// 每次自己Post資料給API的時候都要用這個key來對所有欄位進行簽名,生成的簽名會放在Sign這個欄位,API收到Post資料的時候也會用同樣的簽名演算法對Post過來的資料進行簽名和驗證
// 收到API的返回的時候也要用這個key來對返回的資料算下簽名,跟API的Sign資料進行比較,如果值不一致,有可能資料被第三方給篡改
// API_KEY 在微信商戶號上獲取,不懂找度娘
public static String API_KEY = "XXXXXXXXXXXXXXXXXX";
// 微信分配的公眾號ID(開通公眾號之後可以獲取到)
public static String APP_ID = "wx97a1ceeXXXXXXXXX";
// 微信支付分配的商戶號ID(開通公眾號的微信支付功能之後可以獲取到)
public static String MCH_ID = "123456789012";
// 機器IP
public static String CREATE_IP = getLocalHostAddress();
// 回撥地址,很重要
public static String NOTIFY_URL = "http://www.回撥域名.com/加你的回撥地址";
// 獲取微信支付返回xml的地址
public static String UFDODER_URL = "https://api.mch.weixin.qq.com/pay/unifiedorder";
public static String getLocalHostAddress() {
InetAddress addr = null;
try {
// 獲取本機的相關資訊並儲存在addr
addr = InetAddress.getLocalHost();
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return addr.getHostAddress().toString();
}
}
XMLUtil
將引數封裝成xml,這裡需用到jar包——jdom4.jar,找度娘下載
package com.yc.weixinutil;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.input.SAXBuilder;
public class XMLUtil {
/**
* 解析xml,返回第一級元素鍵值對。如果第一級元素有子節點,則此節點的值是子節點的xml資料。
*
* @param strxml
* @return
* @throws JDOMException
* @throws IOException
*/
public static Map doXMLParse(String strxml) throws JDOMException,
IOException {
strxml = strxml.replaceFirst("encoding=\".*\"", "encoding=\"UTF-8\"");
if (null == strxml || "".equals(strxml)) {
return null;
}
Map m = new HashMap();
InputStream in = new ByteArrayInputStream(strxml.getBytes("UTF-8"));
SAXBuilder builder = new SAXBuilder();
//-----------------------2018-07-21---------------------------------------------
// 參考 http://www.cnblogs.com/hero123/p/9282753.html
// 這是優先選擇. 如果不允許DTDs (doctypes) ,幾乎可以阻止所有的XML實體攻擊
String FEATURE = "http://apache.org/xml/features/disallow-doctype-decl";
builder.setFeature(FEATURE, true);

builder.setFeature(FEATURE, false);

builder.setFeature(FEATURE, false);
System.out.println("2018-07-21 加入了修復XXE攻擊漏洞");
//------------------------------------------------------------------------------
Document doc = builder.build(in);
Element root = doc.getRootElement();
List list = root.getChildren();
Iterator it = list.iterator();
while (it.hasNext()) {
Element e = (Element) it.next();
String k = e.getName();
String v = "";
List children = e.getChildren();
if (children.isEmpty()) {
v = e.getTextNormalize();
} else {
v = XMLUtil.getChildrenText(children);
}
m.put(k, v);
}
// 關閉流
in.close();
return m;
}
/**
* 獲取子結點的xml
*
* @param children
* @return String
*/
public static String getChildrenText(List children) {
StringBuffer sb = new StringBuffer();
if (!children.isEmpty()) {
Iterator it = children.iterator();
while (it.hasNext()) {
Element e = (Element) it.next();
String name = e.getName();
String value = e.getTextNormalize();
List list = e.getChildren();
sb.append("<" + name + ">");
if (!list.isEmpty()) {
sb.append(XMLUtil.getChildrenText(list));
}
sb.append(value);
sb.append("</" + name + ">");
}
}
return sb.toString();
}
}
二、掃碼支付
開始上程式碼,這是正題。我將生成二維碼,執行微信支付,還有回撥地址都放同一controller,這樣方便我。溫馨提示,記得配置action
package com.yc.business.controller;
import java.io.BufferedOutputStream;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;

private static final long serialVersionUID = 1L;
private CommonAdapter commonAdapter;
private Map<String, Object> paramMap = new HashMap<String, Object>();
private Map<String, Object> resultMap = new HashMap<String, Object>();
/**

*/
public void qrcode() {
//doEncoding();
try {
String bId = (String)paramMap.get("bId");
// 獲取支付url
String text = weixinPay(bId);
// 根據url來生成生成二維碼
int width = 300;
int height = 300;
// 二維碼的圖片格式
String format = "gif";
Hashtable hints = new Hashtable();
// 內容所使用編碼
hints.put(EncodeHintType.CHARACTER_SET, "utf-8");
BitMatrix bitMatrix;
try {
bitMatrix = new MultiFormatWriter().encode(text,
BarcodeFormat.QR_CODE, width, height, hints);
MatrixToImageWriter.writeToStream(bitMatrix, format,
response.getOutputStream());
} catch (WriterException e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 執行微信支付

public static String weixinPay(String bId) {
// 以下的各種引數,不懂得在微信支付開發文件裡面可以查詢
String out_trade_no = "yc3312" + System.currentTimeMillis(); // 訂單號

// 這裡說明支付是什麼型別,NATIVE(二維碼),MWEB(H5)
String trade_type = "NATIVE";

}
// 獲取支付的url
String urlCode = (String) map.get("code_url");
return urlCode;
}
/**

}
}
網頁程式碼
這裡需要用到兩個js。layer.js、jquery-3.3.1.min.js
點選觸發payMoney方法
var t1 = 0;
/*
* 點選支付
*/
function patMoney(par){
var bId = $(par).parent().find("input").val();
top.layer.open({
area : [ '300px', '300px' ],
type : 2,
closeBtn : false,
title : false,
shift : 2,
shadeClose : true,
content : '<%=basePath%>page/weixin/qrcode?paramMap.bId=' + bId,
end : function (){
window.clearInterval(t1);
}
});
// 支付進行時,會一直輪詢
t1 = window.setInterval("modifyStatus('"+ bId +"')",3000);
};
function modifyStatus(bId){
var url = '<%=basePath%>page/weixin/haPay';
//輪詢是否已經付費
$.ajax({
type : 'post',
url : url,
data : {"paramMap.bId" : bId},
dataType: "json",
cache : false,
async : true,
success : function(res) {
// 我的資料返回的是狀態1,不明看controller
// 當該狀態為1時,關閉模態框,重新整理網頁
if(res.result == "1"){
top.layer.closeAll();
window.clearInterval(t1);
location.reload();
}
},
error : function() {
layer.msg("執行錯誤!", 8);
}
});
}
以上就是二維碼支付的全部了。
三、H5支付
因為公司框架的原因。controller的執行微信支付方法,我寫在了jsp上。基本一樣,就是加多了一個點選支付完成後,微信幫你返回的地址。
頁面名稱:weixinpay.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page import="com.yc.weixinutil.*" %>
<%@ page import="java.net.URLEncoder" %>
<%@ page import="org.jdom.JDOMException" %>
<%@ page import="java.io.*" %>
<%
String out_trade_no = "yc3312" + System.currentTimeMillis(); // 訂單號
// (調整為自己的生產邏輯)
// 賬號資訊
String appid = PayConfigUtil.APP_ID; // appid
// String appsecret = PayConfigUtil.APP_SECRET; // appsecret
String mch_id = PayConfigUtil.MCH_ID; // 商業號
String key = PayConfigUtil.API_KEY; // key
String currTime = PayToolUtil.getCurrTime();
String strTime = currTime.substring(8, currTime.length());
String strRandom = PayToolUtil.buildRandom(4) + "";
String nonce_str = strTime + strRandom;
// ip地址獲取
String basePath = request.getServerName() + ":"
+ request.getServerPort();
// 獲取發起電腦 ip
String ip = request.getHeader("x-forwarded-for");
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)){
ip = request.getHeader("Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)){
ip = request.getHeader("WL-Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)){
ip = request.getRemoteAddr();
}
String spbill_create_ip = ip.equals("0:0:0:0:0:0:0:1")?"127.0.0.1":ip;
// 回撥介面
String notify_url = PayConfigUtil.NOTIFY_URL;
String trade_type = "MWEB";
SortedMap<Object, Object> packageParams = new TreeMap<Object, Object>();
packageParams.put("appid", appid);
packageParams.put("mch_id", mch_id);
packageParams.put("attach", request.getParameter("bId"));
packageParams.put("nonce_str", nonce_str);
packageParams.put("body", "列印檔案支付"); // (調整為自己的名稱)
packageParams.put("out_trade_no", out_trade_no);
packageParams.put("total_fee", "1"); // 價格的單位為分
packageParams.put("spbill_create_ip", spbill_create_ip);
packageParams.put("notify_url", notify_url);
packageParams.put("trade_type", trade_type);
packageParams.put("scene_info","{\"h5_info\": {\"type\":\"Wap\",\"wap_url\": \"http://www.myssci.com\",\"wap_name\": \"奧科\"}}");
String sign = PayToolUtil.createSign("UTF-8", packageParams, key);
packageParams.put("sign", sign);
String requestXML = PayToolUtil.getRequestXml(packageParams);
String resXml = HttpUtil.postData(PayConfigUtil.UFDODER_URL,
requestXML);
Map map = new HashMap();
try {
map = XMLUtil.doXMLParse(resXml);
System.out.println(resXml);
//確認支付過後跳的地址,需要經過urlencode處理
String urlString = URLEncoder.encode("http://www.域名.com/返回的頁面路徑", "GBK");
String mweb_url = map.get("mweb_url") + "&redirect_url=" + urlString;
response.sendRedirect(mweb_url);
} catch (JDOMException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
%>
當然,頁面上的只有一個按鈕而已,我呼叫了這個方法
/*
* 點選支付
*/
function patMoney(par){
var bId = $(par).parent().find("input").val();
window.location.href = basePath + "weixinPay.jsp?bId="+bId;
};
H5支付也完成了。
總結
第一次開發,難免很多東西不會。建議準備好需要用到的東西在來開發(必須有域名)。
第一次寫,我也不知道寫的怎麼樣。希望你們都能測試成功。
