Interface test Tool-jmeter use Note (V: Regular expression extractor)

(The regular expression extractor is one of the JMeter associations) usage scenarios:

There are two HTTP requests, and there is a field "ABCD" in the return data of request a, which is to be used as the entry for request B.

1. How to add

Request a right-to-back processor, regular expression extractor

2. Extract the corresponding value of Taskcode in Request a

To get to this value in the circle, configure the regular expression extractor:

Description

(1) Reference name: The name of the parameter to be referenced by the next request, such as filling in atask, you can use ${atask} to reference it.

(2) Regular expression:

(): The enclosed part is to be extracted.

.: Matches any string. +: one or more times.: Don't be greedy, stop after you find the first match.

(3) Template: Referenced by $$, if there are more than one regular expression in the regular expression, it can be $2$$3$ and so on, which represents the number of the parsed to the title. Example: $1$ represents the 1th value resolved to

(4) matching numbers: 0 for random values, 1 for all values, usually for 0

(5) Default value: If the parameter does not get the value, it defaults to a value let it take, I fill in the error.

3. Gets the value of the incoming B request

See if Request B passes the Atask value as expected
