golang error: "unexpected token..." How to solve it?

Recently, I encountered an error when developing using Golang: "unexpected token...". This error cost me a lot of time to find and fix. In this article, I will share my solution with you, hoping it will be helpful to others who encounter similar problems.

First of all, let us understand this error report. Generally speaking, Golang's compiler will give a clear error message when an error occurs. But sometimes, we encounter some error messages that are difficult to understand, such as "unexpected token...". This error means that symbols or characters that should not appear appear in the code.

Next, let’s see how to solve this problem. Here are some common solutions:

1. Check whether there are grammatical errors in the code

Sometimes, this error may be caused by a grammatical error in the code. Therefore, we need to check whether all brackets, braces, semicolons and other symbols in the code appear in pairs, and there are no missing or redundant characters.

2. Check whether there are extra spaces or newlines in the code

Sometimes, there may be extra spaces or newlines in the code, causing the compiler to not recognize it symbols and characters in it. So, we need to check if there are any extra spaces or newlines in the code and remove them.

3. Check whether there are non-ASCII characters in the code

If there are non-ASCII characters in the code, the compiler may not be able to recognize the symbols and characters in it. So, while writing code, we need to avoid using non-ASCII characters.

4. Check whether the code has version compatibility issues

Sometimes, our code may have version compatibility issues, causing the compiler to not recognize the symbols and characters in it . Therefore, when developing with Golang, we need to pay attention to version compatibility and use the latest version.

5. Check whether there are undefined variables or functions in the code

Sometimes, we will omit to define variables or functions, causing the compiler to fail to recognize the symbols and characters in them . Therefore, when writing code, we need to define and declare every variable or function.

Summary:

The above are some methods to solve the Golang error "unexpected token...". If none of the above methods work, we need to check the error logs and get more information and solutions by searching and consulting senior programmers. I hope this article can be helpful to people who encounter similar problems.
