Varibles

• Local Varibles

• Global Varibles

we have two types of varibles: Local Varibles and global varibles, while Api testing.

Local Varibles

Every rest project case can bind a group of varibles. All the varibles in the group can be used and updated at request building, response validation or Pure script.

• While visually request building, we can use {{varible-name}} in any place like : URL, Header, or Body. it will automaticly be replaced to the target varible value at run time.

• In programming script block, like Pre-Request Script, Response Validation Script and Pure Script, we can also access or update these varibles through a programing interface.
  
  Different programming languag may have diffent interfaces, please check the examples there.

Bind a project case to a group of varibles by click the “vars” button under the case.

we can also add/delet/modfy these varible definitions in the varible editor.

• Varibles Access in Golang programing

Here is how the GetVars/SetVars is defined for RestBirdCtx. So you can use ctx.GetVars(key)/ctx.SetVars(key, value) to access the varibles.

func (ctx *RestBirdCtx) GetVars(key string) string {
	return ctx.Vars[key]
}

func (ctx *RestBirdCtx) SetVars(key string, value string) {
	ctx.Vars[key] = value
}

Besides, access the varibles in the ctx. We can also pull out all the varibles in a through callapi.GetEnvs(env) to get the whole map of varibles.

• Varibles Access in Python programing

All the Varibles are stored in ctx.vars dictionary. We can directly access it through ctx.vars[key]

Global Varibles

sometimes we would like to share something between a runing rest project and a runing tasks, we can use following method to access the global shared varibles

• Varibles Access in Golang programing

To Access the golobal varibles :

• callapi.SetGlobal(key, value)
• error, value = callapi.GetGlobal(key)

BTW, don’t forget to import callapi package.

• Varibles Access in Golang programing

To Access the golobal varibles through ctx :

• ctx.SetGlobal(key, value)
• value = ctx.GetGlobal(key)
