3. How to use

Run ab-n 100-c http://keketour.me/

the http://keketour.me/ The site makes 100 requests, and 10 requests concurrently

98. 99% 437

100. 100% 437 (Longest request)

Attention:

When simulating a login, you only need to set a cookie:

1. After logging in with your account and password, use the Developer tool to find the cookie value (session ID) that identifies the session.

2. If only one cookie is used, simply type the command:

ab-n 100-c 10-c jiang_token= 3820aab5-a395-48b2-8d2b-87bf47026e78

http://keketour.me/

If more than one cookie is required, set the header directly:

ab-n 100-h "cookie:key1=value1; Key2=value2 " http://keketour.me/

Test API interface (here is an example of adding a travel scheme)

ab-n 10-c 5-p/var/www/kkt/post.txt-v 3 - h "cookie:jiang_token=3820aab5-a395-48b2-8d2b-87bf47026e78; X-requested-with:xmlhttprequest " - t application/x-www-form-urlencoded" http://keketour.me/product/ Tourinfo/savetournameajax "

Where Post.txt is the post parameter text, the content is

name= Pressure Test Stroke Plan &tour_id=0&product_id=1382&_method=patch

Summarize:

AB Tool AB is small, simple, quick to learn, can provide the basic performance indicators needed, but no graphical results, can not be monitored. The AB tool can therefore be used as a temporary emergency task and as a simple test.
