JMeter基礎：請求參數Parameters 、Body Data的區別

 

使用Jmeter測試時，很多人不知道請求參數Parameters 、Body Data的區別和用途，這裏簡單介紹下:

 

先了解一個接口的基本概念

在客戶機和服務器之間進行請求-響應時，HTTP協議中包括GET和POST兩種基本的請求方法，概念上兩者的區別是：

    get：從指定的資源請求數據。
    post：向指定的資源提交要被處理的數據

最直觀的表現就是：

GET把參數包含在URL中，POST通過request body傳遞參數將請求整體提交給服務器。所以接口測試時要區分兩種方法對待。

 

Jmeter中包含Parameters和Body Data兩種參數化的方式，區別是什麼呢？

    使用Parameters時，Content-Type不傳，或者直接傳application/x-www-from-urlencoded，若傳application/json出錯。
    使用Body Data時，Content-Type可傳application/x-www-from-urlencoded或application/json，兩者的區別是數據格式不同。
