Interface test advanced interface script use - apipost (pre / post execution script)

Action time of pre execution script

A pre executed script is a script executed before a request is sent .

The role of pre executed scripts

Pre executed scripts can do the following ：

• To write JS Functions to achieve complex calculations ;

• Variable printing

• Definition 、 obtain 、 Delete 、 Clear environment variables

• Definition 、 obtain 、 Delete 、 Clear global variables

• Get request parameters

• Dynamic addition 、 Delete one header Request parameters

• Dynamic addition 、 Delete one query Request parameters

• Dynamic addition 、 Delete one body Request parameters

• send out HTTP request

To write JS Functions to achieve complex calculations

We can define a function in the pre execution script _random,

function _random(){
 return ' Hello , China ' + Math.random();
}

It returns a string ：“ Hello China ”+ random number , At this time, you can use the

apt.globals.set("random_var", _random());

Assign it to a global variable random_var.

Pre execution script prints debug variables

We can go through console.log() Print the required variables on the console , To see the current value of a variable . As shown in the example above

Definition 、 obtain 、 Delete 、 Clear environment variables

apt.variables.set("key", "value"); //  Set a value to value Environment variables of key
apt.variables.get("key"); //  Get environment variables key Value
apt.variables.delete("key"); //  Delete environment variables key
apt.variables.clear(); //  Clear all defined environment variables

Definition 、 obtain 、 Delete 、 Clear global variables

apt.globals.set("key", "value"); //  Set a value to value Global variable of key
apt.globals.get("key"); //  Set a value to value Global variable of key
apt.globals.delete("key"); //  Set a value to value Global variable of key
apt.globals.clear(); //  Clear all defined global variables

Get request parameters

adopt request Object get request parameters , Details can be referred to 《APIPOST Built-in variables 》 Section 1 document .

Dynamic addition 、 Delete one header Request parameters

apt.setRequestHeader("key", "value"); //  Dynamically add a key to key The value is value Of header Parameters
apt.removeRequestHeader("key"); //  Delete header The key in the parameter is key Parameters of

Dynamic addition 、 Delete one query Request parameters

apt.setRequestQuery("key", "value"); //  Dynamically add a key to key The value is value Of query Parameters
apt.removeRequestQuery("key"); //  Delete query The key in the parameter is key Parameters of

Dynamic addition 、 Delete one body Request parameters

apt.setRequestBody("key", "value");//  Dynamically add a key to key The value is value Of body Parameters   Only aim at  form-data、urlencode It works
apt.removeRequestBody("key");// Delete body The middle key is key Parameters of   Only aim at  form-data、urlencode It works

send out HTTP request

We can use... In pre - executed scripts AJAX Of $.ajax Method to send a http request . Here is a simple example demo： Send a request to... Using a pre executed script

https://echo.apipost.cn/get.php

, And will respond to the results bigint Assigned to a global variable bigint.

$.ajax({
 url:"https://echo.apipost.cn/get.php",
 method:"POST",
 headers:{
 "content-type":"application/json"
 },
 timeout:"10000",
 async:false, //  Remember that this is set to  false, The request must be synchronized
 data:JSON.stringify({"email":"[email protected]","password":"123456"}), 
 success:function (response) {
 apt.globals.set("bigint",response.bigint); 
 }
}
