 1-A auth-username:password
 2      #  支持基本的验证证书,用户名和密码之间使用"冒号"                    :
 3      # 分隔开,ab将以明文方式传送过去.不管服务器是不是需要
 4      # ,也就是说你的服务器需要支持401认证.
 5
 6-c concurrency
 7      # 同时向服务器端发送的请求数目，默认状态下是一次 只执行一个http请求.
 8
 9-C cookie-name=value
10      # Add a Cookie: line to the request. The argument is typically in the
11      # form of a name=value pair. This field is repeatable.
12
13-d    #  Do not display  the  "percentage  served  within  XX  [ms]  table".
14      # (legacy support).
15
16-e csv-file
17      # Write  a  Comma  separated value (CSV) file which contains for each
18      # percentage (from 1% to 100%) the time (in milli seconds) it took to
19      # serve  that percentage of the requests. This is usually more useful
20      # than the 'gnuplot' file; as the results are already 'binned'.
21
22-g gnuplot-file
23      # Write all measured values out as a 'gnuplot' or TSV  (Tab  separate
24      # values)  file.  This file can easily be imported into packages like
25      # Gnuplot, IDL, Mathematica, Igor or even Excell. The labels  are  on
26      # the first line of the file.
27-h    # 显示使用说明
28-H custom-header
29      # 向请求包追加附加的标题字串.此参数应该是有效的标题         行(header
30      # line)形式,通常使用冒号":"来分隔有效配对 (valid  pair)例如  'Accept-
31      # Encoding: zip/zop;8 bit';
32
33-i    # 使用一个 http 头(HEAD) 来替换 GET方法.不可以掺入POST 方法
34
35-k    #  允许http      KeepAlive      ；也就是说执行多个请求在一个      http
36      # 会话当中，默认是不允许的也就是no KeepAlive啦;)
37
38-n requests
39      # 执行一次测试会话的时候所发出的请求数目,默认是执行一个单一的请求
40      # 当然了这样的测试结果也就没什么意义了
41
42-p POST-file
43      # 测试程序也就是ab,将向Apache server发送带有HTTP POST 的请求.
44
45-P proxy-auth-username:password
46      # 当需要通过代理测试一台 HTTP 服务器的时候而你的代理
47      # 又需要用户名密码验证,这时你可以使用这个选项,同样
48      # 用户名与密码之间使用冒号":"分隔开,ab将之以明文的方式
49      # 发送出去,当然,前提是你的代理是处于407认证状态的
50
51-q    #  When processing more than 150 requests, ab outputs a progress count
52      # on  stderr  every  10% or 100 requests or so. The -q flag will sup‐
53      # press these messages.
54
55-s    #  When compiled in (ab -h will show you) use the SSL protected  https
56      # rather  than  the  http  protocol. This feature is experimental and
57      # very rudimentary. You probably do not want to use it.
58
59-S    #  Do not display the median and standard deviation values,  nor  dis‐
60      # play  the  warning/error  messages  when the average and median are
61      # more than one or two times the standard deviation  apart.  And  de‐
62      # fault to the min/avg/max values. (legacy support).
63
64-t timelimit
65      #  设置测试的时间的长短，使用这个选项ab将自动设置
66      # 测试请求会话数目为50000，然后以你设置的时间为
67      # 固定周期.默认状态下是没有时限的，也就是直到完成
68      # 你所设置的请求数目为止.
69
70-T content-type
71      # 内容类型标头,使用在POST数据的时候.
72
73-v verbosity
74      # 设置冗余级别,4级打印出每个请求标头的详细信息,
75      # 3级打印出回应代码(例如,404,200),2级打印出警告 信息和指示消息
76
77-V    # 显示版本号并且退出
78-w    # 打印输出结果到HTML表中. 默认的表是两列n行白底黑框
79
80-x <table>-attributes
81      # 使用字串来描述表的属性,该属性字串应该插入到<table 这里 >
82
83-X proxy[:port]
84      # Use a proxy server for the requests.
85
86-y <tr>-attributes
87      # 用于生成html表格每行的属性名 (<tr>)
88
89-z <td>-attributes
90      # 用于生成html表格每列的属性名 (<td>)
