在本章中,我们将学习如何同时测试多个URL。为此,我们将需要编辑我们的应用程序文件app.py以包括两个URL-
from bottle import Bottle, run
app = Bottle()
@app.route('/')
@app.route('/hello1')
def hello():
return "Hello World! It is first URL."
@app.route('/hello2')
def hello():
return "Hello World! It is second URL."
run(app,server = 'gunicorn',host = '127.0.0.1', port = 8080)
您可以通过创建带有多个ab调用的shell脚本来完成此操作。创建一个文件test.sh并添加以下几行:
ab -n 100 -c 10 http://127.0.0.1:8080/hello1
ab -n 100 -c 10 http://127.0.0.1:8080/hello2
添加以上各行后,保存并关闭文件。使文件可执行-
chmod u+x test.sh
现在让我们运行脚本-
./test.sh
为避免重复和清晰起见,我们将仅显示ab输出的相关内容,并用点表示已省略了哪些部分,如下所示。

您可以通过创建带有多个ab调用的shell脚本,将Apache Bench输出保存到文件中。在每行的末尾放置&;这使命令在后台运行,并让下一条命令开始执行。您还希望使用
$ ab -n 100 -c 10 http://127.0.0.1:8080/hello1 > test1.txt &
$ ab -n 100 -c 10 http://127.0.0.1:8080/hello2 > test2.txt &
在这里, test1.txt和test2.txt是用于保存输出数据的文件。
您可以检查上述脚本是否已创建两个文件test1.txt和test2.txt,其中包含相应URL的ab输出-
$ ls -l
...
-rw-r--r-- 1 root root 5225 May 30 12:11 out.data
-rwxr--r-- 1 root root 118 Jun 10 12:24 test.sh
-rw-r--r-- 1 root root 1291 Jun 10 12:31 test1.txt
-rwxr--r-- 1 root root 91 Jun 10 13:22 test2.sh
-rw-r--r-- 1 root root 1291 Jun 10 12:31 test2.txt
...
使用ab时,您应该对失败的测试保持警惕,而不会发出警告。例如,如果您检查了错误的URL,则可能会得到类似于以下内容的信息(我们在此故意更改了端口)。
$ ab -l -r -n 100 -c 10 -k -H "Accept-Encoding: gzip, deflate" http://127.0.0.1:805/
