jmeter 生成随机数（手机号）&随机中文字符

（一）随机数生成方法

1、BeanShell 预处理程序

//定义手机号前3位
String[] FirstThreeNumber = {"134","135","136","137","138","139","147","150","152","157","158","159","172","178","182","183","184","187","188","198","130","131","132","145","155","156","166","171","175","176","185","186","166","133","149","153","173","177","180","181","189","199"};
 
//随机获取前三位手机号的index
int n= (int)(Math.random() * FirstThreeNumber.length);
//获取手机前三位
String yy = FirstThreeNumber[n];
//循环获取手机号后8位
for(int i = 0; i < 8; i++){
	int x = (int)(Math.random() * 9);
	yy = yy + x;
};
vars.put("com_phone", yy);

　调用随机数

2、BeanShell 预处理程序，利用时间戳+随机数生成手机号，减少重复（注：图中用了后置处理程序错误，并且只能固定前三位使用，并且暂时不知json格式如何做到字符与变量一起传递）

 

（二）生成随机中文字符

1、利用函数RandomString

${__RandomString(1,赵钱孙李周吴郑王冯陈褚卫蒋沈韩杨朱秦尤许何吕)}${__RandomString(2,文林欣德和泽子墨鸿哲兴贤良翰翰池景澄乐成俊)}

2、BeanShell 预处理程序

import java.util.Random;
 
public class Random_str {
public static String RandomJianHan(int len) {
String ret = "";
for (int i = 0; i < len; i++) {
String str = null;
int hightPos, lowPos; // 定义高低位
Random random = new Random();
hightPos = (176 + Math.abs(random.nextInt(39))); // 获取高位值
lowPos = (161 + Math.abs(random.nextInt(93))); // 获取低位值
byte[] b = new byte[2];
b[0] = (new Integer(hightPos).byteValue());
b[1] = (new Integer(lowPos).byteValue());
try {
str = new String(b, "GBk"); // 转成中文
} catch (UnsupportedEncodingException ex) {
ex.printStackTrace();
}
ret += str;
}
return ret;
}
}
 
Random_str ran = new Random_str();
String companyname = ran.RandomJianHan(5);//此处生成的是长度为5的字符串
vars.put("companyname",companyname);
 
Random_str ran = new Random_str();
String content1 = "随机生成内容："+ran.RandomJianHan(10);//此处生成的是长度为10的字符串
