ab相关指令&＃xff1a;

Options are:-n requests Number of requests to perform&＃xff08;请求的总数&＃xff0c;默认是1次。&＃xff09;-c concurrency Number of multiple requests to make&＃xff08;并发数&＃xff0c;同一时间请求数。&＃xff09;-t timelimit Seconds to max. wait for responses-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 for POSTing, eg.&＃39;application/x-www-form-urlencoded&＃39;Default is &＃39;text/plain&＃39; &＃xff08;设置请求头中的Content-type&＃xff08;针对POST/PUT&＃xff09;&＃xff0c;比如&＃xff1a;application/x-www-form-urlencoded。默认是text/plain。&＃xff09;-v verbosity How much troubleshooting info to print-w Print out results in HTML tables &＃xff08;将测试结果打印到HTML表格中。&＃xff09;-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. &＃39;Apache&＃61;1234&＃39;. (repeatable)-H attribute Add Arbitrary header line, eg. &＃39;Accept-Encoding: gzip&＃39;Inserted after all normal header lines. (repeatable)-A attribute Add Basic WWW Authentication, the attributesare a colon separated username and password.-P attribute Add Basic Proxy Authentication, the attributesare a colon separated username and password.&＃xff08; 如果后面接的是文件&＃xff0c;表示POST请求&＃xff0c;文件中包含请求数据&＃xff0c;根据数据格式&＃xff0c;设置-T参数。&＃xff09;-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.-g filename Output collected data to gnuplot format file.-e filename Output CSV file with percentages served-r Don&＃39;t exit on socket receive errors.-h Display usage information (this message)

实例&＃xff1a;

ab -c 300 -n 300 "http://www.abc.com:80/test/aaaa?a&＃61;1&b&＃61;2&c&＃61;3"

测试结果样例&＃xff1a;

Concurrency Level    并发数多少&＃xff0c;等于-c后面的数值
Time taken for tests    测试总耗时
Complete requests    成功收到返回的数目
Failed requests    请求失败数目&＃xff0c;可能因为网络连接&＃xff0c;异常&＃xff0c;请求数据长度等等
Non-2xx responses    表示返回的HTTP status code不是2xx的数目&＃xff08;比如404,401,500...&＃xff09;&＃xff0c;如果都是2xx&＃xff0c;这个指标不显示在结果里面
Requests per second    每秒请求数&＃xff0c;等于总请求数/测试总耗时
Time per request    每一个请求平均花费时间。第一个Time per request等于concurrency * timetaken * 1000 / done&＃xff0c;第二个Time per request&＃xff08;mean, across all concurrency requests&＃xff09;等于timetaken * 1000 / done&＃xff0c;第一个可以理解为用户平均请求等待时间&＃xff0c;第二可以理解为服务器平均请求等待时间
