Loadrunner脚本篇——从文件中读取内容并参数化

直接代码展示：

char* testfn()

{

int count, total = 0;

char * buffer = NULL;

int filelenth = 0;

long file_stream;

char * filename = "F:\test.txt";

if ((file_stream = fopen(filename, "r")) == NULL )

{

lr_error_message ("Cannot open %s", filename);

return NULL;

}

fseek(file_stream,0,2); //定位到文件末尾

filelenth = ftell(file_stream); //获取文件总长度

fseek(file_stream,0,0); //定位文件开头

buffer = (char *)malloc(filelenth); //动态分配内存

count = fread(buffer, sizeof(char), filelenth, file_stream); //读取文件

lr_output_message ("%d bytes read", count);

lr_output_message ("content read = %s", buffer );

if (fclose(file_stream))//关闭文件

{

lr_error_message ("Error closing file %s", filename);

}

return buffer;

}

Action()

{

char *pt = NULL;

pt = testfn();

lr_save_string(lr_eval_string(pt), "param");

lr_output_message("value of param: %s",lr_eval_string("{param}"));

free(pt); //释放内存

return 0;
}

运行结果：
