This article "XMPP protocol, IM, client interconnection how to configure" most people do not understand, so the editor summarized the following content, detailed, clear steps, with a certain reference value, I hope you can get something after reading this article, let's take a look at this "XMPP protocol, IM, client interconnection how to configure" article.

1. What is XMPP? let's talk about XMPP here. In the sdk summary article I mentioned in the previous section, IM's SDK provides commercial XMPP protocols, and of course, some are self-implemented protocols, such as Tencent. XMPP is simply a rule defined between sending and receiving, but this protocol is a little different from our traditional protocol, it is not a binary way, nor a string, but a content in XML format, I believe everyone is familiar with the expansibility of XML,xml is very strong, XMPP also inherits its fine tradition, which makes it easier for us to define our own logo in communications. 2, xmpp server openfire xmpp open source server there are many, we introduce here based on the XMPP protocol server, Openfire. Openfire is based on the Jabber protocol (XMPP) to achieve instant messaging server-side version, using java to achieve, its official website is: http://www.igniterealtime.org/index.jsp the current version of Openfire is 4.0.1, it can be deployed on mac,windows and linux systems. Here, I will take the windows version of the server as an example. After downloading openfire on the official website, click install directly, and the installation steps will follow the way we usually install the software. Here is a hint: if the installation is successful, openfire will not start automatically, then it is possible that the port is occupied. Xmpp generally uses ports of 5222, 5223, etc., you can check whether it has been occupied.

If you do not start by yourself after installation, you can try to start by clicking start manually. Generally, we need to configure the server after installation. If the configuration page pops up, you can skip this step. If not, you can click launch admin, as shown in the figure.

After entering the configuration page, we will be prompted for the language displayed on the page. We will choose simplified Chinese here. For example, after selecting the language in the figure, we need to set up the server and enter our domain name\ IP address. If encryption is needed, we need to configure encrypted public key, private key and so on. I choose the default one here. After the figure is configured, we choose the database method. It is explained here that if we need to connect to a database that has already been installed, choose the first method. If we do not install it locally, we can choose the second method. As shown in the figure, because I choose the first method here, then we need to configure our ODBC connection method. My one here uses MYSQL. Enter the address of the database service and the name of the database, as well as the user name and password, and then enter the attributes in the user group. We choose the default here, such as entering the administrator's account number and password in the figure. It must be noted here that the default administrator account and password are admin and admin. If you need to change it to our own password, you can change it at this step, but you must remember, otherwise, It needs to be modified in the database, and the account number should be modified in the form of mailbox. As shown in the figure, the configuration of the server is complete. We can see the configuration information of our openfire on the management platform. As shown in the figure, for the installation of the mac version, click install after downloading. After the installation is complete, we may not know where the installation is. We can open the preferences, reopen it to be valid, and then open the openfire button, as shown in the following figure. We can directly click start openfire to open our mac version of the server, in addition, once again, if you can not open the openfire to check that the port inside is not occupied. 3. Test client Spark. Here we directly use the Spark on the official website to test our real-time information. Download spark on the official website, click install, and after installation, we need to register an account and the steps to register the account, as shown in the figure below. What we need to pay attention to here is the server address. The address here is the domain name address we just entered. We can enter the IP address of the server. If you are testing locally, you can enter 127.0.0.1 or all domains, or domain names, depending on the situation. The download address of spark, http://www.igniterealtime.org/downloads/index.jsp#spark, will automatically pop back to the login page after registration. We can log in to the corresponding interface by entering the account number and password, and will display a page similar to Fetion, showing that we are online, as shown in figure 4. Test the group message. When we log in to the management platform, we want to use the background to send a message to the client. We click session-> tools-> send a message, and then enter our content, such as hello. After clicking send, the client will receive the hello, indicating that the real-time content has arrived.
