之前的后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之后再導入，麻煩。

快遞鳥有電子面單api，后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，但是遇到的坑著實是不少，特此記錄一下。

快遞鳥電子面單API地址：http://www.kdniao.com/api-eorder

都是在正式環境下，申請對應的商戶id等一系列東西。

在對應的快遞鳥后臺，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修改為對應的版本就可以了。

官方demo代碼

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，則透過防火墻獲取真實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，并不是簽名問題，而是ip問題。

因為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，在后臺將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，安裝完成之后訪問?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)，要不我也不至于出差了。

之后根據打印機型號，進入對應的官網下載打印驅動。之后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。

?lodop有云打印機，目前并不清楚，需要的話可以再研究下。
