jmeter - 在jmeter中获取随机用户定义的变量

Question

I have user defined variable like this.

url_1
url_2
url_3
.
.
.
url_n

In HTTP Request sampler i have to randomly select any one of these URL's .So in server name textbox i am trying this ${url_${__Random(1,7)}} But it is not fetching the variable. How can i fetch the value of that variable. I am also getting the following error.

java.net.URISyntaxException: Illegal character in authority at index 7: http://${url_${__Random(1,7)}}/ at java.net.URI$Parser.fail

Answer 1

使用__V() function喜欢:

${__V(url_${__Random(1,7,)})}

根据函数文档:

For example, if one has variables A1,A2 and N=1:

• ${A1} - works OK
• ${A${N}} - does not work (nested variable reference)
• ${__V(A${N})} - works OK. A${N} becomes A1, and the __V function returns the value of A1
