Loadrunner Socket协议日志输出_loadrunner buf0-优快云博客

本文介绍了一个使用Socket进行TCP通信的示例程序。该程序创建了一个到远程主机的连接，并发送了一个名为buf0的数据包，接收返回的数据包并解析响应代码。此外还展示了如何通过lrs库函数统计数据包长度及转换响应代码。

char *buf0;
int ActucalNumber;
int respcode;
int length;
int Numberofbuf0;
int rc;
rc=lrs_create_socket("socket3", "TCP", "RemoteHost=162.16.1.46:9001",LrsLastArg);
if (rc==0)
lr_output_message("Socket3 was successfully created ");
else
lr_output_message("An error occurred while creating the socket, Error Code: %d", rc);
lrs_send("socket3", "buf0", LrsLastArg);
lrs_receive("socket3", "buf1", LrsLastArg);
lrs_get_buffer_by_name("buf0",&buf0,&Numberofbuf0);

//获取send buf的包的长度,在修改发送包buf0的时候自动统计包长

ActucalNumber=lrs_get_last_received_buffer_size("socket3");

//socket接收到buf动态包长，由于返回的数据包的包长动态变化，所以lrs_save_param_ex操作时需要获取ActualNumber

lrs_save_param_ex("socket3","received",NULL,0,ActucalNumber,"ascii","param1");

//获取返回数据的字符串
lrs_save_param_ex("socket3","received",NULL,32,4,"ascii","param2");

//respcode在接口返回字符串中的位置为32~36
length=strlen(lr_eval_string("<param2>"));

//获取rspcode字符串的长度，lrs_hex_string_to_int函数用
lrs_hex_string_to_int(lr_eval_string("<param2>"),length,&respcode);

//字符型转换成整形，方便在日志中查看respcode结果
lrs_close_socket("socket3");
