Introduction to how to use Postman

When developers need to debug whether a webpage is running normally, it is not simply to debug whether the HTML, CSS, scripts and other information of the webpage are running normally. What is more important is that the webpage can correctly handle various HTTP requests. After all, the HTTP request of the webpage is a very important way for the website to interact with the user. In a dynamic website, most of the user's data needs to interact with the server through HTTP requests.

The Postman plug-in acts as a "bridge" for this interaction method. It can use the Chrome plug-in to send various data that simulates user HTTP requests to the server, so that developers can make correct responses in a timely manner, or handle error messages before product release in advance, thereby ensuring the stability and security of the product after it is launched.

After installing the Postman plug-in in Chrome, users only need to start the Postman plug-in when debugging the website and perform a few simple configurations to modify the basic information of the website and send various types of HTTP to the website. When sending HTTP data, users can add a certain amount of parameter information when writing relevant test data to make the test data more accurate, and Postman will perfectly support all of this.

When developers use Postman, they may need to frequently debug the same website or debug multiple websites at the same time. It will be very troublesome if they have to reset it every time they open the Postman plug-in. Postman also takes into account the personalized needs of users, so in the Postman configuration page, users can add or manage multiple websites. When users start Postman, the corresponding settings will be automatically opened.
