Locust學習筆記5——登錄接口參數關聯

　　引言

　　前面在Locust學習筆記3——模擬登錄案例(非加密) 講了登錄接口，但是這個登錄的接口並不需要動態參數以及加密簽名等校驗，而且也沒有繼續講登錄後的操作。現在這篇文章主要講上下接口關聯的場景，比如接口A返回的數據，作爲接口B的請求參數。

　　之前講的登錄接口是Vue的接口，現在我以學信網爲例:https://account.chsi.com.cn/passport/login，講一下參數關聯的場景。

　　獲取參數

　　使用抓包工具Fiddler，我們登錄學信網後，可以看到這樣的請求參數信息：

 

　　可以看出，每次登錄成功，請求參數中都會有lt參數和execution參數，並且每次都不一樣，

　　lt 參數是每次打開瀏覽器，訪問登錄首頁時服務端會返回一個新的數據

　　execution 參數是表示網站刷新次數，可以刷新下再登錄，就變成其他了

　　也就是這兩個參數是動態的，那麼這兩個參數是從哪裏獲取呢？

　　我們退出學信網，直接請求登錄頁面(get請求:https://account.chsi.com.cn/passport/login)，查看返回的html內容：

　　備註：上面可以看出，我使用了requests.session()方法，作用是創建一個session會話，當你使用這個session登錄之後，再次使用session請求系統其他頁面的時候，默認使用session會話之前使用的cookie參數。例如JSESSIONID

 

 

 

 　　requests.session()會自動保存，這樣就實現cookie關聯，get_execution_lt()這個函數其實已經獲取到了cookies參數。

　　總結

　　到此，以登錄後請求其他接口的案例已經講完，在實際項目中可以根據這個思路來壓測需要登錄後的接口。有興趣的朋友可以加入測開交流羣進行溝通與學習，一起成長！
