快遞鳥基於java功能打印電子面單api接口

之前的後天管理系統的電子面單打印使用的是靈通打單。

使用相對比較麻煩,需要到處Excel之後再導入,麻煩。

快遞鳥有電子面單api,後臺系統直接對接很是方便,不過也遇到了好些問題。

不難是不難,但是遇到的坑着實是不少,特此記錄一下。

快遞鳥電子面單API申請地址:http://www.kdniao.com/reg

都是在正式環境下,申請對應的商戶id等一系列東西。

在對應的快遞鳥後臺,可以進行如下的批量打印。

想把這個打印功能集成到自己內部系統,可以下載官方的demo

跑起來挺容易的,直接放入tomcat運行就可以了

不過demo需要tomcat8.5,需要修改的話找到項目的.settings文件夾下有一個

org.eclipse.wst.common.project.facet.core.xml 將tomcat8.5修改爲對應的版本就可以了。

            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有一個ip參數,獲取這個ip快遞鳥提供的方法是如下

// 獲取請求主機IP地址,如果通過代理進來,則透過防火牆獲取真實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;
    }

注意這個方法是沒有問題的,但是你如果直接輸入快遞單號OrderCode進行打印,這個時候提交總是說數據驗證不通過,並不是簽名問題,而是ip問題。

因爲上一個方法只要是在局域網下面,即使能訪問外網,也沒用,獲取到的ip永遠都是內網ip

有一種方式可以在本地驗證通過,那就是直接百度ip,只有會有自己的ip地址

OK,在後臺將ip寫死,就可以進行打印預覽操作了。

打印需要安裝lodop打印插件,安裝完成之後訪問 http://localhost:8000/CLodopfuncs.js 會有相應的控件js

需要對應的打印插件,必須要有設備(熱敏打印機),要不我也不至於出差了。

之後根據打印機型號,進入對應的官網下載打印驅動。之後perfect,就可以進行打印了。

官方demo給的是servlet

我使用的是SpringMVC,將代碼貼出。

    final String AppKey = "8e9dcb4b-f0a1-42f6-9d80-372a67f851**"; //kdniao.com AppKey
    final Integer IsPreview = 1; //是否預覽 0-不預覽 1-預覽
