性能工具之locust工具get與post請求

最近在學習 locust 性能工具，發現locust性能工具腳本需要python基礎才能寫腳本，但是對於性能測試人員來說 python 是基本功夫。

 

     在 locust 中get腳本怎么寫，為了方便直接在代碼運行調試，采用關閉web模式，通過參考官方文檔自己實驗get/post代碼，參考代碼如：

@task(1) def get_7dTest(self): # 定義請求頭 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請求寫法如下

 # 登陸 @task(1) def get_login(self): response = self.client.post("/login", {"userName": "7d", "passWord": "123456"}) print("Response json:", response.json())

結果：

# 結果：[2021-04-24 21:36:49,495] liwen.local/INFO/locust.main: Run time limit set to 1 seconds[2021-04-24 21:36:49,495] liwen.local/INFO/locust.main: Starting Locust 1.4.4[2021-04-24 21:36:49,496] liwen.local/INFO/locust.runners: Spawning 1 users at the rate 1 users/s (0 users already running)...[2021-04-24 21:36:49,496] liwen.local/INFO/locust.runners: All users spawned: webTestDunShan: 1 (1 total running)[2021-04-24 21:36:49,496] liwen.local/INFO/root: Terminal was not a tty.

post請求json請求寫法：

@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())# 結果Response json: {'msg': 'success', 'code': 0, 'data': '登陸成功'}

 

實驗請求資源代碼：

 @GetMapping("/7d") @ResponseBody public R indexPage() { HashMap<String, Object> map = new HashMap<>(); map.put("success", "歡迎來到性能實戰課堂"); map.put("Data", new Date()); return R.ok().put("data", map); }

/** * 登陸 * * @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", "登陸成功"); } return R.error().put("data", "用戶名或者密碼失敗"); }

 /** * 登陸 * * @param requestBody * @return */ @PostMapping(value = "/login/json", produces = "application/json") @ResponseBody public R login_json(@RequestBody String requestBody) { log.info("json數據：{}", 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", "登陸成功"); } return R.error().put("data", "用戶名或者密碼失敗"); }

 

locust直接在 python 代碼調試代碼關閉web頁面，這樣調試很方便，參考如下命令：

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界面運行測試。
# -c 設置虛擬用戶數。
# -r 設置每秒啟動虛擬用戶數。
# -t 設置設置運行時間。
# 結果參考：

總結：

     locust 官方文檔還是比較詳細，只要慢慢看就能掌握locust工具怎么操作，但是在老師性能工程中，工具只要能發壓就行。
