  1. Script examples

Using scripts to modify request messages

You can use pm.request to read or modify request messages.
You can use scripts to get all request parameters, but you can only use scripts to modify header and query parameters.
Modifying header and query parameters are only valid in preprocessor scripts, not in postprocessor scripts.
Using scripts to get API parameters: if the parameter contains a variable, it will not be replaced with the corresponding value. You need to use the pm.variables.replaceIn to get the actual value.
// pm.variables.replaceIn: handling variables in parameters
var body = pm.variables.replaceIn(pm.request.body.raw);
var jsonData = JSON.parse(body);
TIP
In Apidog pre processors, there is a Built-In preprocessor named Variable Substitution, which replaces all variables (including dynamic variables) in the request with the actual value.
Scripts like set variable need to be placed before Variable Substitution so that the variable can be set successfully.
Scripts like API signature need to be dragged after Variable Substitution to get actual values of the parameters.

Body parameters#

Body parameters come from pm.request.body which is a RequestBody instance.
View more details here.
TIP
We recommend referencing variables in the Body to modify body data. You can modify the value of the corresponding variable in preprocessor scripts.
We support direct modification of body parameters in Apidog version 1.4.16 or higher. See example of how to use it below:
var body = pm.request.body.toJSON();
console.log("body object", body);

var bodyStr = body.raw;
console.log("body string", bodyStr);

var bodyJSON = JSON.parse(bodyStr);
bodyJSON.id = 100;
pm.request.body.update(JSON.stringify(bodyJSON, null, 2));
console.log("Modified body", pm.request.body.toJSON());

Get form-data info.

2. Body Type: x-www-form-urlencode#

Get x-www-form-urlencode info.

3. Body Type: JSON#

Get JSON info.

4. Body Type: raw#

Get raw info.
