sign To please seek Step Abrupt

1、 preparation ：

Check in thread group
n HTTP Request defaults
n HTTP cookie Manager
n Home page access request
n Login request
n View the result tree
n Commissioning the samplers
l HTTP proxy server

（1） Create thread group

（2）HTTP The proxy server recording script is saved under a thread group

（3） The browser opens the proxy
2、 Start the proxy server recording script , Check in with the browser , After checking in, close the browser agent

3、 End recording script , Run the request again , View content request content , The figure below , Sign in request 、 Course check-in list . Make sure you catch the request you want , Then modify the request name ;

From 4 The contents to be added at the beginning of step are ：CSV Data file settings 、 Regular expression extractor

4、 Single modification of check-in information —— Add a regular expression extractor to the course check-in list before check-in
Regular expressions ：“bsq0h0”:“(.+?)”,"（ If there are spaces in the expression , Just delete , Otherwise, the execution result may not change , Or the results may not be consistent with expectations ）
5、 Modify the check-in status
6、 Run view results ,bsq0h0 To change the value of 1, Refresh the page to show that you have checked in ;bsq0h0 To change the value of 0, Refresh the page to show that you have not checked in .

The batch operation , The first three steps are the same as the single check-in steps

The following content starts directly from step 4

7、 use CSV Sequential batch operation of files ;

8、 At the first “ Course check-in list ” Add regular expression extractor

（1） Regular expressions ：“bsq0h0”:“(.+?)”,"（ If there are spaces in the expression , Just delete , Otherwise, the execution result may not change , Or the results may not be consistent with expectations ）
（2） Matching numbers refer to CSV Value in file ;
0、 Check in page , Call the check-in list row extracted by regular expression id, Modify check-in status

Sign in for class , Extract course id. Reference variable name ：${kcqdid};
Check in , quote id,1 Sign in ,0 To be signed in ;
use CSV Document the course check-in sequence , In extracting courses according to CSV File sequential extraction course id.
10、 Modify the number of thread group cycles
11、 Run thread group , If you sign in bsq0h0 To change the value of 1, Refresh web page , All sign in status displays
Signed in ;bsq0h0 To change the value of 0, Refresh web page , All check-in statuses show pending check-in
