我有一个自定义的 httpclient, 我创建了这个客户端, 来接收我的自定义信托商店, 并将其用于它试图访问的所有 SSl 网站。 这里的代码是 :

public class MyHttpClient extends DefaultHttpClient {

    private Context context;

    public MyHttpClient(Context context) {

        this.context = context;
    }

    @Override
    protected ClientConnectionManager createClientConnectionManager() {

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory
                .getSocketFactory(), 80));
        registry.register(new Scheme("https", newSslSocketFactory(), 443));
        return new SingleClientConnManager(getParams(), registry);
    }

    private SSLSocketFactory newSslSocketFactory() {

        try {
            KeyStore trusted = KeyStore.getInstance("BKS");
            InputStream in = context.getResources().openRawResource(
                    R.raw.cacerts);
            try {
                trusted.load(in, "changeit".toCharArray());
            }
            catch (CertificateException c) {
                System.out
                        .println("There was a certificate exception in myhttpclient!");
            }
            finally {

                in.close();
            }
            return new SSLSocketFactory(trusted);
            }
            catch (Exception e) {
                throw new AssertionError(e);
            }
    }
}

并在这里的堆叠追踪 它给了我:

现在,这个操作正确... 大约50%的时间。 我“ 解决了”, 创建了一个时空循环 。 它继续重新创建 httpclient 客户端, 并尝试反复访问服务器, 直到它正常工作, 通常只经过1到2次尝试( 我所看到的最多是4次 ) 。 显然, 这非常低效 。

I ve narrowed down the problem to the class I ve posted above, since if I create the httpclient just once and try to access the site using that same class multiple times, it will either always fail, or always succeed, depending on whether I got a good httpclient, or a bad httpclient. However, if I create the httpclient every single time I try and access the webpage, it will sometimes work and sometimes not work.

那么为什么它要这么做呢? 我怎样才能解决这个问题呢? 为什么它只是间歇运作, 客户创造之间会发生什么变化呢?

解决了!

似乎我把一些古老的化名留在了信托店里,它随机地选择了它首先找到的哪一个,但最终并不总是正确。每个化名都有相同的证书,但每个化名都有不同的顺序。我测试了直到我找到正确的商店,删除了其余的,现在一切都完美无缺。
