Errors 是一个用于优雅地处理 Go 中错误的库。
- 优雅地处理错误，嗯，没了。。。
历史版本的特性请查看 HISTORY.md。未来版本的新特性和计划请查看 FUTURE.md。
package main
import (
"fmt""io""github.com/FishGoddess/errors"
)
funcmain() {
// Use wrap function to create an *Error error which has code and message.// You can get code and message of err anytime.err:=errors.Wrap(1000, "need login")
fmt.Println(err)
fmt.Println(err.Code(), err.Message())
// Try these ways to get code and message!// You will get default code or message if err doesn't have a code or message.code:=errors.Code(err, 6699)
message:=errors.Message(err, "default message")
fmt.Println(code, message)
code=errors.Code(io.EOF, 6699)
message=errors.Message(io.EOF, "default message")
fmt.Println(code, message)
// Also, we provide some useful information carrier for you.// For examples, you can carry an error, caller information or some args.// Remember the count of args should be even and their keys should be a string.err=errors.Wrap(9999, "io timeout").With(io.EOF).WithCaller().WithArgs("user_id", 123, "timeout", "200ms")
fmt.Println(err)
fmt.Println(errors.CodeMessage(err, 6666, "default message"))
// What's more, we provide some shortcuts for you.// All these ways are returning *Error and you are free to use all methods on *Error.berr:=errors.BadRequest("id is wrong")
ferr:=errors.Forbidden("user isn't allowed")
nerr:=errors.NotFound("book not found")
fmt.Printf("%+v\n%+v\n%+v\n", berr, ferr, nerr)
isBadRequest:=errors.IsBadRequest(berr)
isForbidden:=errors.IsForbidden(ferr)
isNotFound:=errors.IsNotFound(nerr)
fmt.Printf("isBadRequest: %+v\nisForbidden: %+v\nisNotFound: %+v\n", isBadRequest, isForbidden, isNotFound)
}如果您觉得 errors 缺少您需要的功能，那就 fork 到自己仓库随便玩。当然，也可以提 issue :)。
