Answer 1

vars保存字符串值，您可以在放置值时转换双精度值：

vars.put("unixTimeValue", String.valueOf(a));

Answer 2

You can change your lines 1-14 to:您可以将第 1-14 行更改为：
```
 vars.put("RANDOM_STRING", org.apache.commons.lang.RandomStringUtils.randomAscii(12))
```
See RandomStringUtils class JavaDoc for more potentially useful functions有关更多潜在有用的功能，请参阅RandomStringUtils 类 JavaDoc
Change your line 20 to:将第 20 行更改为：
```
 vars.putObject("unixTimeValue", sin);
```
as vars.put() function accepts only Strings while vars.putObject() accepts pretty much everything, see JMeterVariables class JavaDoc for more details由于vars.put()函数只接受字符串，而vars.putObject()接受几乎所有内容，有关更多详细信息，请参阅JMeterVariables 类 JavaDoc
Since JMeter 3.1 you should be using Groovy language for scripting mainly because Groovy has much better performance comparing to Beanshell, see Apache Groovy - Why and How You Should Use It article for comprehensive explanation with examples 从 JMeter 3.1 开始，您应该使用 Groovy 语言编写脚本，主要是因为与 Beanshell 相比，Groovy 具有更好的性能，请参阅Apache Groovy - Why and How You Should Use It文章以通过示例进行全面说明
