使用apache http客户端通过代理进行HTTP

Question

我有一个基于apache http客户端的http客户端,它似乎没有ssl证书的问题.我对全球认可的证书和自签名证书进行了单元测试,并使用自定义SSLSocketFactory.

但是当我在代理后面运行相同的代码时,它停止了工作.我一直得到这个可怕的例外:

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
at com.sun.net.ssl.internal.ssl.SSLSessionImpl.getPeerCertificates(SSLSessionImpl.java:352)
at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:128)
at org.apache.http.conn.ssl.SSLSocketFactory.connectSocket(SSLSocketFactory.java:572)
at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:180)
at org.apache.http.impl.conn.ManagedClientConnectionImpl.open(ManagedClientConnectionImpl.java:294)
at org.apache.http.impl.client.DefaultRequestDirector.tryConnect(DefaultRequestDirector.java:640)
at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:479)
at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:906)
at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:805)

我将代码减少到最低限度,它仍然会抛出相同的异常.代码:

    URI uri = new URI("https://www.google.com");
    DefaultHttpClient client = new DefaultHttpClient();
    client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, 
            new HttpHost("proxy.int", 8080, "https"));

    HttpUriRequest request = new HttpGet(uri);
    HttpResponse response = client.execute(request);

如果没有指定任何内容,我不确定它是否使用默认的ssl设置,所以我也明确地添加了它:

    URI uri = new URI("https://www.google.com");
    DefaultHttpClient client = new DefaultHttpClient();
    client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, 
            new HttpHost("proxy.int", 8080, "https"));

    client.getConnectionManager().getSchemeRegistry().register(
            new Scheme("https", 443, SSLSocketFactory.getSystemSocketFactory()));

    HttpUriRequest request = new HttpGet(uri);
    HttpResponse response = client.execute(request);

我也尝试了getSocketFactory()(不完全确定与getSystemSocketFactory()的区别,但仍然是同样的错误.

编辑:

代理具有可选的身份验证,我已尝试使用和不使用.使用以下代码设置身份验证信息:

    client.getCredentialsProvider().setCredentials(
        new AuthScope("proxy.int", 8080),
        new UsernamePasswordCredentials("user", "password")
    );

完全相同的错误.

问题出在代理声明中,我不得不指定"http"而不是"https":

client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, 
        new HttpHost("proxy.int", 8080, "http"));
