快递鸟电子面单打印功能基于java

之前的后天管理系统的电子面单打印使用的是灵通打单。

使用相对比较麻烦，需要到处Excel之后再导入，麻烦。

快递鸟有电子面单api，后台系统直接对接很是方便，不过也遇到了好些问题。

不难是不难，但是遇到的坑着实是不少，特此记录一下。

快递鸟电子面单API地址：http://www.kdniao.com/api-eorder

都是在正式环境下，申请对应的商户id等一系列东西。

在对应的快递鸟后台，可以进行如下的批量打印。

想把这个打印功能集成到自己内部系统，可以下载官方的demo

跑起来挺容易的，直接放入tomcat运行就可以了

不过demo需要tomcat8.5，需要修改的话找到项目的.settings文件夹下有一个

org.eclipse.wst.common.project.facet.core.xml 将tomcat8.5修改为对应的版本就可以了。

            }
        } else if (ip.length() > 15) {
            String[] ips = ip.split(",");
            for (int index = 0; index < ips.length; index++) {
                String strIp = (String) ips[index];
                if (!("unknown".equalsIgnoreCase(strIp))) {
                    ip = strIp;
                    break;
                }
            }
        }
        return ip;
    }

}

但是，需要注意的是，API有一个ip参数，获取这个ip快递鸟提供的方法是如下

// 获取请求主机IP地址,如果通过代理进来，则透过防火墙获取真实IP地址
    public final static String getIpAddress(HttpServletRequest request) throws IOException {
        String ip = request.getHeader("X-Forwarded-For");
        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
            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.getHeader("HTTP_CLIENT_IP");
            }
            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                ip = request.getHeader("HTTP_X_FORWARDED_FOR");
            }
            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                ip = request.getRemoteAddr();
            }
        } else if (ip.length() > 15) {
            String[] ips = ip.split(",");
            for (int index = 0; index < ips.length; index++) {
                String strIp = (String) ips[index];
                if (!("unknown".equalsIgnoreCase(strIp))) {
                    ip = strIp;
                    break;
                }
            }
        }
        return ip;
    }

注意这个方法是没有问题的，但是你如果直接输入快递单号OrderCode进行打印，这个时候提交总是说数据验证不通过，并不是签名问题，而是ip问题。

因为上一个方法只要是在局域网下面，即使能访问外网，也没用，获取到的ip永远都是内网ip

有一种方式可以在本地验证通过，那就是直接百度ip，只有会有自己的ip地址

OK，在后台将ip写死，就可以进行打印预览操作了。

打印需要安装lodop打印插件，安装完成之后访问 http://localhost:8000/CLodopfuncs.js 会有相应的控件js

需要对应的打印插件，必须要有设备(热敏打印机)，要不我也不至于出差了。

之后根据打印机型号，进入对应的官网下载打印驱动。之后perfect，就可以进行打印了。

lodop有云打印机，目前并不清楚，需要的话可以再研究下。

年轻人，fighting！！！
