java Apache HttpClient和自定义端口

Question

我使用的是ApacheHttpClient 4，它运行良好。唯一不起作用的是自定义端口。似乎根目录被提取，端口被忽略

HttpPost post = new HttpPost("http://myserver.com:50000");
HttpResponse response = httpClient.execute(post);

如果没有定义端口，http和https连接工作正常。 方案注册处的定义如下：

final SchemeRegistry sr = new SchemeRegistry();

final Scheme http = new Scheme("http", 80,
      PlainSocketFactory.getSocketFactory());
sr.register(http);

final SSLContext sc = SSLContext.getInstance(SSLSocketFactory.TLS);
  sc.init(null, TRUST_MANAGER, new SecureRandom());
SSLContext.setDefault(sc);

final SSLSocketFactory sf = new SSLSocketFactory(sc,
      SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

final Scheme https = new Scheme("https", 443, sf);
  sr.register(https);

如何为请求定义自定义端口

Answer 1

问题是服务器不理解HTTP 1.1分块传输。我使用字节数组缓存了数据，一切正常

因此，自定义端口可以使用上述代码

Answer 2

另一种方法是将httpClient配置为使用自定义SchemaPortResolver

int port = 8888;
this.httpClient = HttpClients.custom()
        .setConnectionManager(connectionManager)
        .setConnectionManagerShared(true)
        .setDefaultCredentialsProvider(authenticator.authenticate(url,
                port, username, password))
        .setSchemePortResolver(new SchemePortResolver() {
            @Override
            public int resolve(HttpHost host) throws UnsupportedSchemeException {
                return port;
            }
        })
        .build();

这样，您就避免了使用字符串构造HttpPost并调用httpClient.execute(host, httpPost, handler, context)的问题，只会在路径后添加，比如：http://localhost/api:8080，这是错误的
