EasyLanguage UPD Server Introduction and Usage Instructions
Introduction
EasyLanguage is a high-level programming language that is known for its simplicity, ease of use, and flexibility. One of its key features is its ability to interact with other software, devices, and networks. To achieve this, EasyLanguage has built-in libraries for TCP/IP and UPD communications. This article focuses on the UPD server and how to use it.
What is a UPD Server?
A UPD server is responsible for handling UPD packets sent from clients over the network. UPD stands for User Datagram Protocol, which is one of the core Internet protocols. Unlike TCP, UPD does not establish a connection between the sender and receiver. Instead, UPD packets are sent to a specific port number on the receiver’s machine. UPD is often used for applications that require real-time delivery of data or for applications that do not need a reliable, ordered protocol.
The EasyLanguage UPD server is a program that listens on a specified port number for incoming UPD packets. When a UPD packet arrives, the server reads the packet’s data and processes it according to the application’s requirements. The UPD server can also send UPD packets to clients over the network.
Installing the EasyLanguage UPD Server
The EasyLanguage UPD server is included with the EasyLanguage package. To install it, follow these steps:
1. Launch the EasyLanguage installer program.
2. Select “Custom Installation.”
3. When prompted to select components to install, make sure the “UPD Server” component is selected.
4. Follow the on-screen instructions to complete the installation.
Configuring the EasyLanguage UPD Server
Before using the UPD server, you need to configure it. This involves specifying the port number the server will listen on and any other settings that may be required.
To configure the UPD server, follow these steps:
1. Launch the EasyLanguage UPD Server Configuration program.
2. Select the “Settings” tab.
3. Specify the port number the server will listen on.
4. Configure any other settings that may be required.
5. Click “Save” to save the settings.
Using the EasyLanguage UPD Server
Once the UPD server is installed and configured, you can start using it in your EasyLanguage programs. To do this, you need to include the UPD library in your program.
To use the UPD library, follow these steps:
1. Open your EasyLanguage program.
2. Click “Project” followed by “Add Library.”
3. Select the “UPD” library from the list of avlable libraries.
4. Click “OK” to add the library to your program.
5. Write your program and include the necessary UPD functions.
Example Implementation
To illustrate how to use the EasyLanguage UPD server, consider the following example. In this example, we will create an UPD server that listens on port 8080 for incoming packets. When a packet arrives, the server will read the packet’s data and echo it back to the sender.
Program:
“`c
#include
#include
byte packet[1024];
int mn(){
UPD_Server server;
server.Port=8080;
server.Start();
while(1){
int bytes=server.Receive(packet,1024);
if(bytes>0){
server.Send(packet,bytes);
}
}
return 0;
}
“`
Explanation:
We start by including the EasyLanguage and UPD libraries. We then define a byte array `packet` to hold incoming packets.
Next, we declare an instance of the `UPD_Server` class called `server`. We set the `Port` property of the server to 8080 and call the `Start` method to start the server.
We then enter an infinite loop where we wt for incoming packets. When a packet arrives, we read it into the `packet` array using the `Receive` method. We then use the `Send` method to send the same packet back to the sender.

有关易语言服务器、客户的端口映射一些问题
做了映射，在广域网就用公网地址+端口访问就可以
对，就是要用端口映射物哗旦。
之一个参数的话要填你电脑的外网ip（查外网ip：在百度搜索输入 ip ，罩扰按回车就可也看到了）。
第二个参数是填你映射的那个端口，还有服务端芦兆的端口应该和你映射的端口一致才可以！
