使用ab 进行post压力测试

对于模拟GET请求进行测试，ab非常简单，就是：ab -n 100 -c 10 'http://testurl.com/xxxx?para1=aaa&para2=bbb'

对于模拟POST请求进行测试，则稍微复杂些，需要把将要post的数据（一般是json格式）放在文件里。比如一个post接口需要如下方式访问

curl -H 'Content-Type:application/json' -X POST  -d '{"actionType":"collect","appId":1,"contentId":"1770730744","contentType":"musictrack","did":"866479025346031","endType":"mobile","recommendId":"104169490_1_0_1434453099#1770730744#musictrack#USER_TO_SONG_TO_SONGS#gsql_similarity_content2content","tabId":0,"uid":"104169490"}' http://localhost:8083/query/leui/v0/post/user/behavior/content

需要吧-d 后面的json数据放在一个文件里，比如建立一个文件post_data.txt，放入：

{"actionType":"collect","appId":1,"contentId":"1770730744","contentType":"musictrack","did":"866479025346031","endType":"mobile","recommendId":"104169490_1_0_1434453099#1770730744#musictrack#USER_TO_SONG_TO_SONGS#gsql_similarity_content2content","tabId":0,"uid":"104169490"}

然后用-p参数解析并发送这个json数据：ab -n 100 -c 10 -p post_data.txt -T 'application/json' http://localhost:8083/query/leui/v0/post/user/behavior/content
