LR十六：socket_tcp协议_loadrunner测试

1、lrs_create_socket("socket0", "TCP", "RemoteHost=127.0.0.1:8888", LrsLastArg)，创建socket连接

2、lrs_send("socket0", "buf0", LrsLastArg)，发送buf中的数据

3、lrs_receive("socket0", "buf1", LrsLastArg)，接收服务器返回的数据，并保存到一个buf1中

4、lrs_save_param("socket0",NULL,"RecivedData",0,-1)，获取服务器返回的数据，并保存到一个参数中RecivedData，最后两个参数，偏移量和length

5、lrs_save_searched_string("socket0",NULL,"RecivedData","LB/BIN=|","RB/BIN=|",1,0,-1)，获取服务器返回的数据，并指定了左右边界，过滤出想要的数据，保存到一个参数中，最后三个参数分别为，取值序号、偏移量、保存长度

6、lrs_close_socket("socket0")，关闭链接

设置超时
lrs_set_recv_timeout2
当定义的buf长度与实际不匹配时，可以将接受数据的时间设置为0，避免等待的情况。


send buf0 10
	"123"
	recv buf1 19

　　

自编socket 接口源代码

import java.io.InputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class TcpServer {

    public static void main(String[] args) {
        try {
            ServerSocket serverSocket = new ServerSocket(8888);
            System.out.println("server start...");
            while (true){
                Socket socket = serverSocket.accept();
                InputStream inputStream = socket.getInputStream();
                byte[] by = new byte[1024];
                int len = inputStream.read(by);
                System.out.println("Msg from "+socket.getInetAddress().getHostAddress()+":"+new String(by,0,len));
                OutputStream outputStream = socket.getOutputStream();
                outputStream.write("|0|SUCCESS|1000913|".getBytes());
                outputStream.flush();
            }
//            socket.close();
        }catch (Exception e){
            e.printStackTrace();
        }
    }
}

测试脚本源码

#include "lrs.h"


Action()
{
//开始事务
    lr_start_transaction("tcp");
//建立连接
    lrs_create_socket("socket0", "TCP", "RemoteHost=127.0.0.1:8888", LrsLastArg);
//开始发送 buf0 数据
    lrs_send("socket0", "buf0", LrsLastArg);
//接收并保持一个buf1
    lrs_receive("socket0", "buf1", LrsLastArg);
//相当于提去SUCCESS这个值 ，存惨
    lrs_save_param("socket0",NULL,"RecivedData",3,7);

//事务判断
    //注意 <> 使用参数是尖括号
    if(strcmp(lr_eval_string("<RecivedData>"),"SUCCESS")==0){

//结束事务
        lr_end_transaction("tcp", LR_PASS);

    }else{
        
        lr_end_transaction("tcp", LR_FAIL);

    }


    return 0;
}

data.ws需要添加这几行

send buf0 10
"<num>"
recv buf1 19
