Postman uses techniques

Environment

In the upper right corner of Postman, there is an icon in the shape of an eye. You can click Set Environment to avoid global pollution

Pre-requestScript

You can write javascript before sending a request such as the backend interface needs to pass in the timestamp, do not need to open Chrome to print the timestamp every time, before initiating a request, write in pre-requestScript, use double curly braces in the header reference.

var date = new Date();
date=Math.round(date/1000)


pm.environment.set("timestampHeader", date);

var data = {
"user":"admin"."psw":"123456"
}
// Get environment information
pm.environment.get("url")
const echoPostRequest = {
  url: 'api'+'/v1/xxx',
  method: 'POST',
  header:'Content-Type:application/json',
  body: {
    mode: 'raw',
    raw: JSON.stringify(data)
  }};
  pm.sendRequest(echoPostRequest, function (err, res) {
    console.log(res.json());
});

console.log(echoPostRequest)
Copy the code

{{timestampHeader}}
