I. Introduction
Some time ago, I wrote an article on getting started with postman, which briefly introduced the interface layout and usage of postman. I saw a topic today: How did you systematically learn IT technology?
I think this topic is very interesting, so I will briefly talk about my views on this topic from two aspects based on the content of the previous article. I think we can learn from two aspects, whether it is learning IT technology or learning other knowledge, such as Chinese, mathematics, English, etc. learned in school.
One is through learning by analogy, and the other is through systematic learning.
Second, learning by analogy
Not long ago, the company held an Ask Me Anything tea party. The senior leader who answered the question was a doctor of a famous university. A colleague asked him a question: What do you think are good learning methods?
He mentioned a few points, but what impressed me the most was the learning method of drawing inferences from one instance, and I very much agree with his point of view.
I think the learning method of drawing inferences from one instance has two characteristics.
One of the characteristics of drawing inferences from one example is the ability to learn quickly. Learning by analogy is also learning by analogy. It is easier to learn by comparing the learning methods of similar things.
It is equivalent to having a foundation when you learn new things and learning more firmly. For example, if you know how to ride a bicycle, you can easily learn to ride an electric bicycle. Because bicycles and electric vehicles have the same characteristics, they are two-wheeled vehicles. The difference is that bicycles need to be stepped on, while electric vehicles can run automatically.
Grasping the common characteristics can learn by analogy, so as to learn quickly. We know that postman is a client that requests HTTP. For us to learn postman, if you have used other HTTP clients before, you can easily learn to use postman. Because HTTP clients are nothing new to you, it's easy to accept.
Another characteristic of drawing inferences from one example is erudition. The so-called inferences from one instance, knowledgeable.
Then let's verify how drawing inferences from one instance can make us knowledgeable.
Since postman is an HTTP client, some parameters on the interface must be related to HTTP. Since you want to learn to use it, then you have to understand the principle of HTTP. Complementary to each other, if you understand the principle of HTTP, then you can use postman better.
The erudition here is that at first you just want to learn how to use postman, but after learning by analogy, you even learn the principles of HTTP. The principle of HTTP is reversed to the use of postman, allowing you to learn postman better.
3. Systematic learning
System is a comprehensive and in-depth study. Sometimes you will find that as long as you systematically learn a skill, you will beat others who have not systematically learned it.
But systematic learning (systematic learning method) is not to detain a certain detail for in-depth study, but to treat the learned content as a system, so systematic learning is not difficult.
How to systematically learn postman? That is to learn it comprehensively, just to distinguish the key points from the non-key points.
The key points are each parameter on the request interface, pre-request scripts, test scripts, environment variables, HTTP principles, etc. But it doesn't mean that every function needs to be figured out. It doesn't make much sense to do so, but it will waste a lot of our time.
By the way, I have one more thing I want to say. Beginners are on the way to masters, first of all they should understand their own deficiencies.
This is not what I said. Some readers may know that this is a sentence that coach Anxi in Slam Dunk said to Hanamichi Sakuragi.
I think this is also a benefit of systematic learning, which allows us to discover our own shortcomings and look at the problem from a global perspective.
Finally, let's talk about the postman series of articles.
I plan to write three articles. The first two introduce the simple introduction of postman and how to learn postman, then the next article will write how to Sinicize postman. Because different people have different habits, many readers are accustomed to the Chinese interface and have a need for Sinicization, so I plan to talk about this topic in the next article.
