I've noticed that there are several similar questions to my own, and after reading some of the documentation, I am still very confused as to how I should go about this. Here's what I know The site that I want to log into utilizes asp.net and the login.aspx uses POST for the login form. There is no API for this website There is also

问题 I am not able to understand the purpose of piped i/o streams in java. If I write something using an outputstream, I can anyways read it again using an inputstream. So what is the need of a pipedstream? 回答1: Short motivation: Separation of concerns (always good - in this case it helps split your code into reading and writing part) Multithreading (previous point lead to "easy" (its never easy :D) parallelization) Long explanation/example: Imagine you have "producer-consumer" like application.

问题 I'm trying to write a program that connects via SSH to a remote Linux server using Java. I've found a number of examples online to do this using the JSch package, but they're mostly for issuing a single command to the server right after authentication. Is there any way, however, to first authenticate with the SSH server, then, over the connection, issue commands from the user input like you would via a remote shell? 回答1: If you want to implement an interactive shell, you need to use SSH

问题 I am new to Azure and sharepoint integration with Java. I am trying to integrate Java with Sharepoint. The Sharepoint-Office 365 is available in Azure ADFS. I need to write a Java program to authenticate and then access the files using the RESTful APIs provided by Sharepoint. Azure is using WS-Federation authentication process. I have been trying to look for the code that helps me to use the WS-F authentication and then access the files. I am not able to find any useful material. The basic
