android EOFException HttpURLConnection getResponseCode

lipoxie 2012-07-20 05:54:23

我在调用HttpURLConnection 的 getResponseCode方法时候，有的时候会报EOFException这个错误
//07-20 16:21:28.040: W/System.err(11065): java.io.EOFException
//07-20 16:21:28.040: W/System.err(11065): at libcore.io.Streams.readAsciiLine(Streams.java:203)
//07-20 16:21:28.040: W/System.err(11065): at libcore.net.http.HttpEngine.readResponseHeaders(HttpEngine.java:544)
//07-20 16:21:28.040: W/System.err(11065): at libcore.net.http.HttpEngine.readResponse(HttpEngine.java:784)
//07-20 16:21:28.060: W/System.err(11065): at libcore.net.http.HttpURLConnectionImpl.getResponse(HttpURLConnectionImpl.java:274)
//07-20 16:21:28.060: W/System.err(11065): at libcore.net.http.HttpURLConnectionImpl.getResponseCode(HttpURLConnectionImpl.java:479)
偶发的，不是每次出现，有谁遇到过这种情况啊，是不是网络不好导致？谁来帮帮忙啊？
