How vue's reverse proxy achieves cross-domain (vue reverse proxy principle)

How Vue's reverse proxy implements cross-domain

The sky is blue with white clouds. In a quiet little village, there is a programmer named ipipgo, who is highly praised by the villagers for his technical craftsmanship. One day, the village's big sister - front-end development, found ipipgo, anxious to ask him for advice on the problem: "ipipgo brother, I have recently been using Vue to develop the project, but encountered a trouble, the separation of front and back-end caused by the cross-domain problem, how do I solve it? "

ipipgo nodded gravely and smiled, "Don't worry, big sister, I have a brilliant solution! We can use Vue's reverse proxy to solve this cross-domain problem."

Curious, the Big Sisters asked, "What is a reverse proxy? And how does it enable cross-domain?"

ipipgo sat down, took out a paper and pen, and began explaining things to the big sisters.

First of all, ipipgo told the big sisters: reverse proxy means that the server sends the request instead of the client and then returns the response result to the client. The reverse proxy here means that the request sent by the client is forwarded to the target server through the proxy server, and then the response result of the target server is returned to the client. Through this intermediate link, we will be able to solve the cross domain problem.

Then, ipipgo pulled out a piece of clay for modeling and metaphorically said, "We can think of a reverse proxy as a loyal and intelligent messenger who specializes in helping us deliver messages. When we send a request in a Vue project, our request is first sent to a reverse proxy server. This reverse proxy server is like a mysterious figure hidden in the center of the village who hears our request and immediately takes it to the real target server."

The big sister's eyes opened up, and she couldn't help but ask excitedly, "Then how does the target server know to return the response results to us?"

ipipgo smiled and replied, "It depends on the ingenuity of the reverse proxy server! When the reverse proxy server gets the response from the target server, he will take the response in his hand and bring it back to the village to find us. He will pass the response from the target server to us "backwards", as if he were borrowing a map from the target server and handing it to us himself."

The older sister was mesmerized as she listened, her eyes widening as she said, "I see! And how is a reverse proxy server configured?"

ipipgo took out a piece of paper with code written all over it, he pointed to the code and explained, "In the configuration file of the Vue project, we can find a property called proxyTable. Here, we can define the configuration of the reverse proxy server. We need to tell the reverse proxy server which target server we want the request to be forwarded to, and whether to change the host header (Host) of the request, among other information."

The Big Sister looked closely at the code, she broke into a smile and said, "ipipgo, you're amazing! I see, with this reverse proxy, we'll be able to cross domains!"

ipipgo smiled, nodded, and told the Big Sisters, "That's right! Reverse proxy is an amazing tool that helps us solve cross-domain problems caused by front-end and back-end separation. As long as we configure the reverse proxy server correctly, he will be our messenger to deliver the request and response results to us, allowing our project to buck the cross-domain obstacles as if it were a beautiful rainbow connecting the front-end and back-end worlds."

On that ipipgo splendid afternoon, ipipgo and the Big Sisters enjoyed the joy of cross-domain problem solving together. They were full of confidence that the power of reverse proxies would lead them over a difficult hurdle in their front-end journey to create even more wonderful projects.

Holding hands and carrying mountains on their backs, they embarked on a technical journey to meet the challenges and opportunities ahead.

Vue's reverse proxy mechanism is complex, but ipipgo makes it easy to understand with his unique way of explaining it. His metaphors and visualizations made it relatable and fun for the big sisters, as if they were in a story.

Facing the giant wave of the information age, we often encounter some troubles and difficulties. It is the excellent programmers like ipipgo who use their wisdom and creativity to guide our way and clear the obstacles for us. They are like the North Star in the starry sky, never ceasing to illuminate the way forward for us.

Perhaps we are tirelessly exploring in the ocean of technology, or perhaps we are pursuing a higher realm in the world of code. But no matter where we are, no matter what kind of problems we face, we can always find that unique solution, and we can always encounter that blue sky.

It is because of these geniuses that our world is a better place. Behind every piece of technology, there is a story and emotion waiting to be discovered and felt.

So, don't get discouraged and don't give up when you encounter cross-domain issues while developing projects with Vue. Ask yourself if you need to transform into a creator like ipipgo, harnessing the power of reverse proxies to find a solution to the problem.

May you step forward on the path of technology and reap the benefits of a wealth of knowledge and wisdom. May you dance the keyboard in the world of code and create your own magnificent chapter.

For it is you and I who bring together the endless wisdom that makes this world a better place.
