英文:
Go: Unable to initialize struct
问题
我无法初始化一个结构体，即使它没有显示任何linting错误，但在编译时会抛出错误。
错误信息如下：
$ go run main.go
# command-line-arguments
.\main.go:19:10: undefined: Application
这是结构体的定义：
/* app.go */
type Application struct {
config struct {
port string // 从命令行标志读取
env string // 从命令行标志读取
api string // 从命令行标志读取
stripe struct {
secret string // 从环境变量读取
key string // 从环境变量读取
}
}
infoLog *log.Logger
errorLog *log.Logger
templateCache map[string]*template.Template
version string
DB *sql.DB
Router *mux.Router
}
这是我如何初始化它的方式：
/* main.go */
app := Application{}
完整的代码在这里。
非常感谢您的帮助！谢谢！
英文:
I am unable to initialize a struct, even though it does not show any linting error, it throws error while compiling
<h3>Error</h3>
$ go run main.go
# command-line-arguments
.\main.go:19:10: undefined: Application
Here's the struct:
/* app.go */
type Application struct {
config struct {
port string // to be read from the command line flag
env string // to be read from the command line flag
api string // to be read from the command line flag
stripe struct {
secret string // to be read from the environment variable
key string // to be read from the environment variable
}
}
infoLog *log.Logger
errorLog *log.Logger
templateCache map[string]*template.Template
version string
DB *sql.DB
Router *mux.Router
}
And here's how I am initializing it:
/* main.go */
app := Application{}

Would really appreciate the help, thanks!

尝试运行go run .（这里你传递的是文件夹而不是文件）或者go run main.go app.go routes.go。
如果你只运行go run main.go，它只会加载main.go，而main.go没有直接引用其他文件中定义的结构体，所以找不到。通过传递包含所有主要文件的文件夹或显式地传递所有文件，就不会有混淆。
英文:
Try running go run . (here you're passing the folder instead of the files) or go run main.go app.go routes.go.
If you just run go run main.go it'll only load main.go which doesn't have any direct reference to the other files so it can't find the struct defined in the other files. By passing the folder containing all the main package files or passing all of the files explicitly then there's no confusion.
