LoadRunner常用函数大全及设置项介绍

在LoadRunner中,常用的函数有很多。今天本篇文章将为您带来loadrunner常用函数大全及设置项的相关介绍,希望能够对您有所帮助!

loadrunner常用函数大全及设置项

1.web参数转C语言参数
  lr_eval_string("{param}"):取出参数{param}中的值,可嵌套在其他函数里使用

2.C语言参数转web参数
  lr_save_string("aaa","param"):将字符串“aaa”或者一个字符串变量,转变成LR的参数{param}
  lr_save_int(123,”param”);将数字123,转变为LR的参数param

3.字符串处理函数
  strcmp:字符串比较函数,若两个值相等,则返回0
  strcpy:字符串拷贝函数,可以把一个字符串拷贝到一个字符数组中
  strcat:字符串拼接函数,可以把一个字符串拼接到一个字符数组中

4.参数数组操作
  lr_paramarr_random("param_arry"):从参数数组param_arry中随机取一个值,注意param_arry不需要加{}
  int size;
  size = lr_paramarr_len("param_arry"):获取参数数组param_arry的长度,并保存到C语言的变量size里
  int value;
  value = lr_paramarr_idx("param_arry",1):获取参数数组param_arry中第1个值,并保存到C语言的变量value里

5.编码转换函数
  lr_convert_string_encoding(lr_eval_string("{msg}"),LR_ENC_UTF8,LR_ENC_SYSTEM_LOCALE,"afterEncodeMsg");
  将LR中的参数{msg},从utf-8编码转换为system_local编码(LR本地编码),最后保存到LR的参数{afterEncodeMsg}中

6.web_url():get接口,一般通过录制生成

7.web_custom_request():post接口,可以测试http接口或者webservice接口,body为json字符串

8.web_submit_data():post接口,可以测试文件上传类型接口。适合get和post请求,主要用于提交form表单,用于post比较多,并且是一个没有上下文依赖关系的函数

9.web_submit_form函数:提交数据的,但是需要有上下文依赖

10.atoi(lr_eval_string("{param}")):将LR参数{param}转换为数字

11.web_reg_save_param:关联函数,一定要写在请求之前,根据左右边界值找到相应的值, 配合strcmp()使用

12.web_reg_find:文本检查点函数,一定要写在请求之前,检查页面的文本内容是否存在,是一个预注册函数,必须放在请求之前。

13.日志函数:

lr_error_message("usersession:%s",lr_eval_string("{userSession}"));//检查是否获取到值,error标红打印方便查看调试。
