golang template
In Go, the template package provides a powerful and flexible way to generate text-based output, such as HTML, XML, or other plain text formats. It allows you to define templates with placeholders and then fill in those placeholders with dynamic data.
Here’s a simple example of using the template package in Go:
package main
import (
"fmt"
"URL"
"os"
)
type Person struct {
Name  string
Age  int
Email string
}
func main() {
// Define a template string
tmplStr := "Hello, {{.Name}}!\nYou are {{.Age}} years old.\nContact: {{.Email}}"
// Create a new template and parse the template string
tmpl, err := template.New("myTemplate").Parse(tmplStr)
if err != nil {
fmt.Println("Error parsing template:", err)
return
}
// Create a Person struct with some data
person := Person{
Name:  "John Doe",
Age:  30,
Email:"*******************",
}
// Apply the data to the template and write the output to stdout
err = tmpl.Execute(os.Stdout, person)
if err != nil {
fmt.Println("Error executing template:", err)
return
}
parse error怎么解决
}
In this example, we define a template string with placeholders ({{.Name}}, {{.Age}}, {{.Email}}). We then create a Person struct with some data. We create a new template using template.New() and parse the template string using Parse(). Finally, we use Execute() to apply the data to the template and write the output to os.Stdout.
When you run this code, it will generate the following output:
Hello, John Doe!
You are 30 years old.
Contact:*******************
This is just a basic example, and the template package provides many more features and functionalities, such as conditionals, loops, and custom functions, to create more complex templates. You can refer to the Go documentation for more information on how to use the template package effectively.
