如何做Java tcp客户端< - > Qt tcp服务器套接字通信

Question

What I want to know is if this is a good way to do this, or if there's another better and optimal one. (This is for a local network only, not Internet)

I'm trying to implement a communication system between a tcp server (written in Qt in windows) and a tcp client (written in java in android) using sockets. This is

I need to basically do two things: transfer files, and transfer some data.

• So, I've decided to use a string based communication method to handle the custom protocol.

• For the data transfer, I've tought to create a xml file with the data (convert the collections to xml markers and set its values), send the file, and then parse it in the other point.

I have not much knowledge in network programming so please give me a hand on this. Thank you.

Answer 1

I made 2 simple client applications using the socket communication for my exams. They both communicate with a Java server, one of them is an android application, the second one is a Qt application (this one should help you as you want to know how to make your Java app communicate with Qt). You can download these 3 applications here . Excuse me if some comments have been made in French, I use to code in English but I'm facing a French jury :P. Take a deep look to NetworkUtil::receiveString(QDataStream &in) method in the Qt application. Also always use qint32 to receive int from the Java application. If you need further explanations please let me know. E-Kami
