路过的大神帮忙看看HttpURLConnection异常

[xiehui_top]

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？？？

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

[无聊找乐]

apache有个httpClient 的包， 用那个写会容易很多。 还是用那个吧

我用httpclient试了一下 ClientProtocolException 这个异常是怎么回事儿啊？

[无聊找乐]

没有代码，没有异常log，没有请求的地址，你叫人家怎么判断啊。 根据异常的名字我只能告诉你 你的http协议中发送了一个错误的信号。 Class ClientProtocolException java.lang.Object java.lang.Throwable java.lang.Exception java.io.IOException org.apache.http.client.ClientProtocolException All Implemented Interfaces: Serializable Direct Known Subclasses: HttpResponseException @Immutable public class ClientProtocolException extends IOException Signals an error in the HTTP protocol. Since: 4.0 See Also: Serialized Form 详见：http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/client/ClientProtocolException.html
