title: “变量提取器”
sort_title: “6”
每个提取器的格式如下:
{
"type": "",
"name": ""
},
实例:
{
"type": "Query",
"name": "username"
},
{
"type": "Header",
"name": "id"
}
以下针对每个条件的格式作解释:
type
即要提取的数据来源,目前包括以下几种:
-
Header K/V
-
Query K/V
-
Post Params K/V
-
Host
-
URI
-
IP
-
Method
name
指的是如果是K/V行的提取来源,name指要提取的key
如以下示例要提取QueryString里的username这个变量:
{
"type": "Query",
"name": "username"
}
