How to develop a simple online social platform using Go language

Introduction:
With the development of social media, people increasingly rely on online social platforms to Communicate, share and connect. In this article, I will introduce how to use Go language to develop a simple online social platform in order to understand the basic concepts and practices of Go language.

1. Build the basic environment
First, we need to install and configure the Go language development environment. Install the Go language on your computer using the installer provided by the official website. Once the installation is complete, set your GOPATH environment variable and make sure you are able to run the "go" command in the terminal.

2. Design database structure
An online social platform needs to store data such as user information, post content, and relationships between users. We can use relational databases to design and manage this data. In this example, we will use MySQL as the database.

Create a database named "social_platform", and then design the following tables:

1. User table (User): stores the user's basic information, such as name, username, Password etc.
2. Post table (Post): stores posts posted by users, including titles, content, creation time, etc.
3. Follow table (Follow): used to store the following relationships between users.
4. Like table (Like): used to store users’ like relationships for posts.

3. Writing back-end code
Using the standard library and third-party libraries of Go language, we can easily write back-end code to handle user requests, operate databases, and generate response results. .

1. Implement user registration and login functions:
   When processing user registration, we need to verify the information entered by the user and store the user information in the database. When processing user login, we need to verify the username and password entered by the user and generate a user Token. We can use the HTTP routing library of the Go language to handle user registration and login requests, and use a hash function or encryption library to protect the user's password.
2. Implementing the post publishing and browsing functions:
   After the user publishes the post, we need to save the post's title, content, creation time, etc. to the database. While browsing posts, we can query the database for post data and return it to the user. We can use the Go language database driver to connect and operate the database, and use the HTTP routing library to handle post publishing and browsing requests.
3. Implementing the follow and like functions:
   When processing user follow requests, we need to store the follow relationship in the database. When processing user like requests, we need to update the number of likes for the corresponding post. We can use the database operations of the Go language to implement these functions, and use the HTTP routing library to handle follow and like requests.

4. Writing front-end code
Writing front-end code can make our social platform more interactive and user-friendly. We can design and develop user interfaces using front-end technologies such as HTML, CSS, and JavaScript.

1. Login and registration page:
   In the login page, we need to display a username and password input box and add a login button. In the registration page, we need to display a form for entering user information and add a registration button. We can use HTML and CSS to create these pages, and use JavaScript to handle user input and send requests.
2. Post list page:
   In the post list page, we need to display the posts posted by all users and provide like and follow buttons. We can create this page using HTML and CSS, and use JavaScript to get the post data from the backend and display it on the page.

5. Testing and Deployment
After completing the above development work, we need to test the system and deploy it to the production environment. We can use the Go language testing framework to write and execute test cases. Then, use tools to deploy the back-end code to the server and the front-end code to the static file server.

Conclusion:
Through this article, we learned how to use Go language to develop a simple online social platform. By designing the database structure, writing back-end code and front-end code, we can implement functions such as user registration, login, publishing posts, browsing posts, following users and liking posts. I hope this article can help you better understand and apply the development capabilities of Go language.
