Jmeter 传 PUT 请求方式

最近用 Jmeter 发送 PUT 请求，踩了个坑，现记录如下：

难点在在于 body 内有一大串 json 形式的内容

1、PUT 请求的 body 内，直接将 json串传 form-data 形式：

结果：压根执行不过去

2、将抓包出来的请求直接传到 jmeter 里面

发现是一大坨，想参数化？改的你想死

那么有啥方法可以既美观大方，又能发成请求呢？

方法：浏览器 f12

利用这个，我们在 jmeter 内，改写请求：

参数全部写在消息体内，各个 key-value 用 & 连接，这样大的 json 串不会成乱码形式，而且请求成功
