前些日子做的微信扫码支付，现在都有点忘了怎么做的了，赶紧记录一下。。
首先先看比较好的案例，帮了我好多好多，太感谢无私奉献的人们了，我选择的模式二开发
一、场景：公司需要在网站上进行微信支付。
二、API：使用微信开放平台的接入微信支付
-扫码支付。微信支付开发者平台链接
三、实现：
一是：按照微信扫码支付规则生成二维码信息.
二是：微信没有提供生成二维码图片的接口。需要我们自己把二维码信息生成到二维码图片中。
1、首先我们要获取微信后台的必要的信息。
public class Configure {
// 每次自己Post数据给API的时候都要用这个key来对所有字段进行签名，生成的签名会放在Sign这个字段，API收到Post数据的时候也会用同样的签名算法对Post过来的数据进行签名和验证
// 收到API的返回的时候也要用这个key来对返回的数据算下签名，跟API的Sign数据进行比较，如果值不一致，有可能数据被第三方给篡改
public static String key = "";
//微信分配的公众号ID（开通公众号之后可以获取到）
public static String appID = "";
public static String appsecret = "";
//微信支付分配的商户号ID（开通公众号的微信支付功能之后可以获取到）
public static String mchID = "";
//HTTPS证书的本地路径
public static String certLocalPath = "D:/wx/apiclient_cert.p12";
//HTTPS证书密码，默认密码等于商户号MCHID
public static String certPassword = "";
/**

*
* @author yanzy 2016-1-18 下午08:19:45
*
* @param request

*/
public static String getClientIp(HttpServletRequest request) {
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();
}
return ip;
}
//随机字符串
public static String getNonceStr() {
String currTime = PayCommonUtil.getCurrTime();
String strTime = currTime.substring(8, currTime.length());
String strRandom = PayCommonUtil.buildRandom(4) + "";
String nonce_st = strTime + strRandom;
return nonce_st;
}
//1）扫码支付API
public static String PAY_API = "https://api.mch.weixin.qq.com/pay/unifiedorder";
//2）退款API
public static String REFUND_API = "https://api.mch.weixin.qq.com/secapi/pay/refund";
//3）退款查询API

//4)查询订单状态

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("

}
return sb.toString();
} catch (IOException e) {

} finally {
try {
if (reader != null)
reader.close();
} catch (IOException e) {
}
}
return null;
}
