JMeter从csv文件读取到数组

Question

Is there any possibility to read files from .csv into array of variables?

Instead of getting:

https://loadtest.com/mo/75245.json

https://loadtest.com/mo/190554MHG.json

https://loadtest.com/mo/190223MJG.json

https://loadtest.com/mo/198533FTR.json

...

I would like to get an array:

https://loadtest.com/mo/75245.190554MHG.190223MJG.198533FTR.19023.HGTYTRWEYRWEHF.1922MHGDGO.json

Does anybody have some idea?

Thank you in advance.

Answer 1

Check out the following JMeter Functions :

• __FileToString() - to read your CSV file into a JMeter Variable
• __split() - to "split" the aforementioned JMeter Variable holding CSV file content into separate variables using any suitable delimited (comma, tabulation symbol, newline, whatever)

A workaround for this, if you don't want to use Groovy, can be using text editor that supports regex (like Notepad++) to restructure your CSV, so that multiple lines are collapsed into a single multi value line.

An example for Notepad++ would be replacing all instances of: ^(.+)\\R(.+)\\R(.+)\\R With $1 $2 $3 To collapse every 3 lines of text into a single line.

Then you can just use that one line as a single variable in JMeter. This way I've passed multiple comma separated Ids into an array in an Http request. Remember to use a different delimiter in JMeter CSV Data Set Config for actual CSV columns, than the one used to delimit your multiple values.
