接口必然需要压测，但有时候往往没有专门压测人员，程序员自己动手。以实名接口为例，传入姓名、×××号上有返回一致、不一致等信息，一致信息则插入用户信息表，下次调用时先查询该表，如果有直接返回结果。

1.restful接口

2.造数据

-- 建表drop table if exists `t_identity_info`;create table `t_identity_info` (  `id` int(11) not null auto_increment comment '主键id',  `real_name` varchar(20) default null comment '姓名',  `id_card` varchar(18) not null comment '×××号',  `create_time` varchar(19) not null comment '创建时间',  primary key (`id`),  key `index_id_card` (`id_card`)) engine=innodb auto_increment=1 default charset=utf8 comment='用户信息表';-- 存储过程drop procedure if exists insert_t_identity_info_data;delimiter ;;create procedure insert_t_identity_info_data()begin declare i int;declare tempName varchar(4);declare tempAreaCode varchar(6);declare tempDate varchar(8);set i = 0;while i < 10000 doset tempAreaCode = concat((CEILING(RAND()*1000 mod 50) + 10),(CEILING(RAND()*1000 mod 50) + 10),(CEILING(RAND()*1000 mod 50) + 10)) ; set tempDate = DATE_FORMAT(date_add(now(), interval - CEILING(RAND()*1000000 mod 10000) day),'%Y%m%d');set tempName = concat(substring('赵钱孙李周吴郑王冯陈褚卫蒋沈韩',CEILING(RAND()*1000 mod 15),1),substring('嘉懿煜城懿轩烨伟苑博伟泽熠彤鸿',CEILING(RAND()*1000 mod 15),1));insert into t_identity_info (real_name,id_card,create_time) values (tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now()),(tempName,concat(tempDate,CEILING(RAND()*100000) mod 9999+1000),now());select count(1) from t_identity_info;set i = i +1; end while; end ;;DELIMITER ;-- 调用存储过程call insert_t_identity_info_data();-- 循环造数据，执行一次数据量*2insert into t_identity_info(real_name,id_card,create_time) select real_name,id_card,now() from t_identity_info;

完成接口的httpclient

3.压测
