Apache HttpClient and custom ports
提问by Stephan
I'm using the Apache HttpClient 4 and it works fine. The only thing that doesn't work is custom ports. It seems like the root directory is fetched and the port is ignored.
我正在使用 Apache HttpClient 4，它工作正常。唯一不起作用的是自定义端口。似乎获取了根目录并忽略了端口。
HttpPost post = new HttpPost("http://myserver.com:50000");
HttpResponse response = httpClient.execute(post);
If no port is defined, http- and https-connections work well. The scheme registry is defined as follows:
如果未定义端口，则 http- 和 https-connections 运行良好。方案注册表定义如下：
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);
How can I define custom ports for a request?
如何为请求定义自定义端口？

The problem was that the server does not understand HTTP 1.1 chunked transfers. I cached the data by using a ByteArrayEntity and all was ok.
问题是服务器不理解 HTTP 1.1 分块传输。我使用 ByteArrayEntity 缓存了数据，一切正常。
So custom ports do work with the code mentioned above.
所以自定义端口确实可以与上面提到的代码一起使用。

One suggestion is to try using HttpPost(URI address)instead of the one with Stringparameter. You can explicitly set the port:
一种建议是尝试使用HttpPost(URI address)而不是带String参数的。您可以显式设置端口：
URI address = new URI("http", null, "my.domain.com", 50000, "/my_file", "id=10", "anchor")
HttpPost post = new HttpPost(address);
HttpResponse response = httpClient.execute(post);
Can't guarantee this will work, but give it a try.
不能保证这会奏效，但请试一试。

Another approach is to configure httpClientto use a custom SchemaPortResolver.
另一种方法是配置httpClient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();
This way, you avoid problems of using a String to construct a HttpPostand calling httpClient.execute(host, httpPost, handler, context), only finding your port is appended afterthe path, like: http://localhost/api:8080, which is wrong.
这样，您可以避免使用 String 构造 aHttpPost并调用 的问题httpClient.execute(host, httpPost, handler, context)，只会发现您的端口附加在路径之后，例如: http://localhost/api:8080，这是错误的。
