前言
最近在学习 Locust 性能工具,发现 Locust 性能工具脚本需要 python 基础才能写脚本,但是对于性能测试人员来说 python 是基本功夫。
脚本示例
在 Locust 中 get 脚本怎么写,为了方便直接在代码运行调试,采用关闭 web 模式,通过参考官方文档自己实验 get/post 代码,参考代码如:
@task(1)
def get_7dTest(self):
# 定义请求头
header =
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (Khtml, like Gecko) Chrome/69.0.3497.100 Safari/537.36"
response = self.client.get("/7d/", headers=header, verify=False)
# print("Response status code:", response.status_code)
if response.status_code == 200:
print("successful")
# print("Response text:", response.json())
else:
print('failure')
Post请求写法如下:
# 登陆
@task(1)
def get_login(self):
response = self.client.post("/login", "userName": "7d", "passWord": "123456")
print("Response json:", response.json())
结果:
# 结果:

Response json: 'msg': 'success', 'code': 0, 'data': '登陆成功'
Response json: 'msg': 'success', 'code': 0, 'data': '登陆成功'
post 请求 json 请求写法:
@task(1)
def get_login_json(self):
jsonData = "userName": "7d", "passWord": "123456"
response = self.client.post("/login/json", json=json.dumps(jsonData))
print("Response json:", response.json())
# 结果
Response json: 'msg': 'success', 'code': 0, 'data': '登陆成功'
实验请求资源代码:
@GetMapping("/7d")
@ResponseBody
public R indexPage()
HashMap<String, Object> map = new HashMap<>();
map.put("success", "欢迎来到性能实战课堂");
map.put("Data", new Date());
return R.ok().put("data", map);
/**
* 登陆
*
* @param memberEntity
* @return
*/
@PostMapping("/login")
@ResponseBody
public R login(MemberEntity memberEntity)
if ("7d".equals(memberEntity.getUserName()) && "123456".equals(memberEntity.getPassWord()))
return R.ok().put("data", "登陆成功");
return R.error().put("data", "用户名或者密码失败");
/**
* 登陆
*
* @param requestBody
* @return
*/
@PostMapping(value = "/login/json", produces = "application/json")
@ResponseBody
public R login_json(@RequestBody String requestBody)
log.info("json数据:", requestBody);
Object parse = JSON.parse(requestBody);
MemberEntity memberEntity = JSON.parseObject(parse.toString(), MemberEntity.class);
if ("7d".equals(memberEntity.getUserName()) && "123456".equals(memberEntity.getPassWord()))
return R.ok().put("data", "登陆成功");
return R.error().put("data", "用户名或者密码失败");
Locust 直接在 Python 代码调试代码关闭web页面,这样调试很方便,参考如下命令:
os.system("locust -f demoLcou.py --host=http://127.0.0.1:8080 --headless -u 1 -r 1 -t 1s")
# –no-web 表示不使用Web界面运行测试。
# -c 设置虚拟用户数。
# -r 设置每秒启动虚拟用户数。
# -t 设置设置运行时间。
# 结果参考:

总结
Locust 官方文档还是比较详细,只要慢慢看就能掌握 Locust 工具怎么操作,但是在老师性能工程中,工具只要能发压就行。
