Loadrunner writes socket script

First, select the windows sockets protocol

Action()
{     lr_save_string(lr_eval_string("<socketid>"),"socket_num");//For the convenience of parameterization, the parameterized content is stored in an ordinary function at the beginning     lr_start_transaction("test" );
    

    

    lrs_create_socket(lr_eval_string("<socket_num>"),"TCP","LocalHost=0","RemoteHost=127.0.0.1:8899",LrsLastArg);

    lrs_send(lr_eval_string("<socket_num>"), "buf0", LrsLastArg); //Send the data in "buf0" to "tt"

    lrs_set_recv_timeout(10, 0);//Set here to return a timeout of 10 seconds

    lrs_receive(lr_eval_string("<socket_num>"), "buf1", LrsLastArg);//Store the data returned in "tt" in "buf1"
    //Note that the length of buf1 needs to be adjusted here to adapt to the actual business data
    
    
    lrs_save_param(lr_eval_string("<socket_num>"), NULL, "jy", 0, 2);

    if(strcmp(lr_eval_string("<jy>"),"ok")==0)
    {
        lr_output_message("成功，交易响应码: %s",lr_eval_string("<jy>"));
        
    lr_end_transaction("test", LR_PASS);

    }
    else
    {         lr_output_message("Failure, transaction response code: %s",lr_eval_string("<jy>"));     lr_end_transaction("test", LR_FAIL);
        

        

    }

    lrs_close_socket(lr_eval_string("<socket_num>"));

    return 0;
}

 The parameterization of <socketid> is tt

You need to use the socketTool tool to simulate the server proxy. You can go online and download it.
