Question

我正在尝试使用ssl将文件上传到某个网址。我使用此代码设置信任管理器 -

public static void trustAll () {
    TrustManage[] trustEverythingTrustManager = new TrustManager[] {
        new X509TrustManager() {

            public void checkClientTrusted(X509Certificate[] chain,
            String authType) throws CertificateException {
            // TODO Auto-generated method stub
            }

            public void checkServerTrusted(X509Certificate[] chain,
            String authType) throws CertificateException {
            // TODO Auto-generated method stub

            }

            public X509Certificate[] getAcceptedIssuers() {
            // TODO Auto-generated method stub
            return null;
            }

        }
    };

    SSLContext sc;
    try {
        sc = SSLContext.getInstance("TLS");
        sc.init(null, trustEverythingTrustManager, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (Exception e) {
    }
}

和这个设置主机名验证器 -

public static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {

    public boolean verify(String hostname, SSLSession session) {
        return true;
    }
};

然后我打开这样的连接 -

URL url = new URL("some_url");
HttpURLConnection connection = null;
// check if this is https or just http
if (url.getProtocol().toLowerCase().equals("https")) {
    trustAll();
    HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
    https.setHostnameVerifier(DO_NOT_VERIFY);
    connection = https;
} else {
    connection = (HttpURLConnection) url.openConnection();
}

在我获得连接后，我使用它来上传数据。我使用http一切正常，但当我尝试https时，我得到以下异常 -

写入错误：系统调用期间的I / O错误，管道损坏 java.io.IOException：写入错误：系统调用期间的I / O错误，管道损坏 at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.nativewrite（Native Method）在org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.access $ 600（OpenSSLSocketImpl.java:55）在org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl $ SSLOutputStream.write（OpenSSLSocketImpl.java:565）在java.io.OutputStream.write（OutputStream.java:82）在org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection $ HttpOutputStream.write（HttpURLConnection.java:652）在java.io.DataOutputStream.write（DataOutputStream.java:101）

奇怪的是，我不会一直得到例外。当我尝试上传小文件（200K）时，它正在工作O.K.或者它的崩溃非常罕见但是当我尝试上传更大的（超过1MB）时，我几乎每次都会得到异常。

有什么想法吗？

来自android的人报告说这是android sdk http://code.google.com/p/android/issues/detail?id=8625中的错误。
