In this tutorial, we will discuss how to use Apache HttpClient 4.5 to make an HTTP GET, POST, PUT and DELETE requests. How to Use Apache HttpClient 4.5 for Https Connections Posted on the 13 February 2017 by Abhishek Somani @somaniabhi This is a simple example on how to use Apache HttpClient 4.5 with connection pool manager to request https urls. I think the main difference is that in java, you usually put the key and the certificate to a key store and use it from there. Like you mention often people do want to use a separate library for it, like mentioned httpcomponents client (just like you're using requests library in your python example). Here's an example of using a client certificate from a key store, using the previously.

P.S Tested with HttpClient 4.5.10.

Customizing SSL in HttpClient

Apache Httpclient 4.5 Ssl Example Pdf

The default behaviour of HttpClient is suitable for most uses, however there are some aspects which you may want to configure. The most common requirements for customizing SSL are:

  • Ability to accept self-signed or untrusted SSL certificates. This is highlighted by an SSLException with the message Unrecognized SSL handshake (or similar) being thrown when a connection attempt is made.
  • You want to use a third party SSL library instead of Sun's default implementation.

Implementation of a custom protocol involves the following steps:

  1. Provide a custom socket factory that implements org.apache.commons.httpclient.protocol.SecureProtocolSocketFactory interface. The socket factory is responsible for opening a socket to the target server using either the standard or a third party SSL library and performing any required initialization such as performing the connection handshake. Generally the initialization is performed automatically when the socket is created.

  2. Instantiate an object of type org.apache.commons.httpclient.protocol.Protocol. The new instance would be created with a valid URI protocol scheme (https in this case), the custom socket factory (discussed above) and a default port number (typically 443 for https). For example:

    The new instance of protocol can then be set as the protocol handler for a HostConfiguration. For example to configure the default host and protocol handler for a HttpClient instance use:

  3. Finally, you can register your custom protocol as the default handler for a specific protocol designator (eg: https) by calling the Protocol.registerProtocol method. You can specify your own protocol designator (such as 'myhttps') if you need to use your custom protocol as well as the default SSL protocol implementation.

    Once registered the protocol be used as a 'virtual' scheme inside target URIs.

    If you want this protocol to represent the default SSL protocol implementation, simply register it under 'https' designator, which will make the protocol object take place of the existing one
