功能如下
对外提供接口 机票查询,航班查询,翻译【汉译英,英译汉,汉译日】
技术框架
php,simple_html_dom.php(一个第三方开源框架,解析html很方便),simplexml_load_string(php5自带工具类,解析xml很方便),正则表达式,网页分析必备技术。
测试接口通过java的http接口进行测试
遇到问题
1.原来php是以脚本命令方式执行没有任何问题,切到apache下报错,最后发现是页面本身协议头中的文件类型有误
原来代码:header("Content-Type:text/xml;charset=utf-8");
调整后: header("Content-Type:text/html;charset=utf-8");
2.编码问题,php本身执行没有乱码,通过java调用出现乱码,调整输入流字符集控制,url参数字符集控制解决
详见java测试类中编码方式。
废话不多说啦,直接贴代码如下:
