HttpClient ThreadSafeClientConnManager 抛出“连接重置”

我用两种不同的方式定义 HttpClient： 1. 普通： client = new DefaultHttpClient(); 2. 线程安全：

DefaultHttpClient getThreadSafeHttpClient() {
    HttpParams params = new BasicHttpParams();
    params
            .setParameter(
                    "http.useragent",
                    "Mozilla/5.0 (Linux; U; Android 1.1; en-us;dream) AppleWebKit/525.10+ (KHTML, like Gecko) Version/3.0.4 Mobile Safari/523.12.2");
    HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
    HttpProtocolParams.setContentCharset(params, "UTF-8");
    final SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", PlainSocketFactory.getSocketFactory(), 443));
    final ThreadSafeClientConnManager manager = new ThreadSafeClientConnManager(params,
            registry);
    return new DefaultHttpClient(manager, params);
}

然后我对两种客户端类型运行相同的 JUnit 测试（简单的 GET 请求）。 #1 总是运行良好，#2 总是失败并显示“java.net.SocketException：连接重置”。调试/stacktrace 输出可以在这里看到（虚构的网站）

我从来没有得到过由于在 client#execute 调用中抛出错误，因此有机会对实体对象执行任何操作。我在这里做错了什么？

I define HttpClient in 2 different ways:
1. Plain vanilla: client = new DefaultHttpClient();
2. Thread safe:

DefaultHttpClient getThreadSafeHttpClient() {
    HttpParams params = new BasicHttpParams();
    params
            .setParameter(
                    "http.useragent",
                    "Mozilla/5.0 (Linux; U; Android 1.1; en-us;dream) AppleWebKit/525.10+ (KHTML, like Gecko) Version/3.0.4 Mobile Safari/523.12.2");
    HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
    HttpProtocolParams.setContentCharset(params, "UTF-8");
    final SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", PlainSocketFactory.getSocketFactory(), 443));
    final ThreadSafeClientConnManager manager = new ThreadSafeClientConnManager(params,
            registry);
    return new DefaultHttpClient(manager, params);
}

Then I run same JUnit test for both client types (simple GET request). #1 always runs fine, #2 always fails with "java.net.SocketException: Connection reset". Debug/stacktrace output can be seen here (fictitious site)

I never get a chance to do anything with entity object since error is thrown at client#execute call. What's I'm doing wrong here?

啊哈！原因是使用错误的套接字工厂定义 HTTPS。应该是 SSLSocketFactory

SSLSocketFactory sslSocketFactory = SSLSocketFactory.getSocketFactory();
sslSocketFactory.setHostnameVerifier(SSLSocketFactory.STRICT_HOSTNAME_VERIFIER);
registry.register(new Scheme("https", sslSocketFactory, 443));

Aha! The reason was in defining HTTPS with wrong socket factory. It should be SSLSocketFactory

SSLSocketFactory sslSocketFactory = SSLSocketFactory.getSocketFactory();
sslSocketFactory.setHostnameVerifier(SSLSocketFactory.STRICT_HOSTNAME_VERIFIER);
registry.register(new Scheme("https", sslSocketFactory, 443));
