路过的大神帮忙看看HttpURLConnection异常
本帖最后由 u010022574 于 2013-09-13 22:13:28 编辑 最近要在公司系统上做一个连接第三方接口进行身份证验证的功能 于是写了下面一个类
首先说明的是能验证成功 但是偶尔会发生405 not allowed 或者连接失败，数据接受错误 大神们看看有什么不合理的地方 为什么会发生405和连接失败呢？？？

} java? HttpURLConnection??
[解决办法]
是不是静态页面接收了post请求了？
你倒是发几个Log信息看一下啊
[解决办法]
apache有个httpClient 的包， 用那个写会容易很多。
还是用那个吧
