自己写代码经常是顺着逻辑写下去,写完后run一下,ok就玩完事了。直到遇到一个又一个的问题的时候才回头过来重新修改。这就是没有测试的悲剧。因此,在今后的代码中一定要尝试着去写测试,去做测试。

发现Apache Server下有个工具ab可以进行并发请求,正好有个需求想要知道并发下的访问情况。

1.下载

访问:http://httpd.apache.org/download.cgi

然后点击:

然后跳到一个页面说只提供源码,自己编译,云彩。不过也提供了推荐第三方编译,选择第一个:

然后是选择镜像和版本,不要选择德国的:

2.安装

我这是买椟还珠的游戏,不想去了解Apache的功能,只想要ab。所以直接解压,然后在bin目录找到ab就可以了:

3.测试

输入ab就可以看到帮助文档

D:\Java\httpd-2.4.23-x64-vc14\Apache24\bin>ab
ab: wrong number of arguments
Usage: ab [options] [http:
//]hostname[:port]/path
Options are:
-n requests Number of requests to perform
-c concurrency Number of multiple requests to make at a time
-t timelimit Seconds to max. to spend on benchmarking
This implies
-n 50000
-s timeout Seconds to max. wait for each response
Default is
30 seconds
-b windowsize Size of TCP send/receive buffer, in bytes
-B address Address to bind to when making outgoing connections
-p postfile File containing data to POST. Remember also to set -T
-u putfile File containing data to PUT. Remember also to set -T
-T content-type Content-type header to use for POST/PUT data, eg.
'application/x-www-form-urlencoded'
Default is
'text/plain'
-v verbosity How much troubleshooting info to print
-w Print out results in HTML tables
-i Use HEAD instead of GET
-x attributes String to insert as table attributes
-y attributes String to insert as tr attributes
-z attributes String to insert as td or th attributes
-C attribute Add cookie, eg. 'Apache=1234'. (repeatable)
-H attribute Add Arbitrary header line, eg. 'Accept-Encoding: gzip'
Inserted after all normal header lines. (repeatable)
-A attribute Add Basic WWW Authentication, the attributes
are a colon separated username and password.
-P attribute Add Basic Proxy Authentication, the attributes
are a colon separated username and password.
-X proxy:port Proxyserver and port number to use
-V Print version number and exit
-k Use HTTP KeepAlive feature
-d Do not show percentiles served table.
-S Do not show confidence estimators and warnings.
-q Do not show progress when doing more than 150 requests
-l Accept variable document length (use this for dynamic pages)
-g filename Output collected data to gnuplot format file.
-e filename Output CSV file with percentages served
-r Don't exit on socket receive errors.
-m method Method name
-h Display usage information (this message)

举例:

D:\Java\httpd-2.4.23-x64-vc14\Apache24\bin>ab -n 20 -c 10 localhost:8080/user/all

-n表示一共请求20次

-c表示并发量为10次。

也就是说,会进行两个并发,每次10个。
