Golang,你好!
panic: relative address in instruction
goroutine 1 [running]:
main.main()
F:/goprjs/demo2/main.go:33 +0x13d
比如type A struct{
//...
}
func (t *A)hello(){
//
}
是否支持对A.hello()进行hook?
直接调用是可以的,但是间接调用就不管用了,不知道是什么原理。
测试代码
import "golang.org/x/net/http/httpguts"
import "fmt"
import "github.com/fengyoulin/hookingo"
func main() {
hookingo.Apply(httpguts.IsTokenRune, func(r rune) bool {
fmt.Println("hookingo:", r)
return true
})
httpguts.IsTokenRune('a')
}
成功
import (
"golang.org/x/net/http/httpguts"
"fmt"
"github.com/fengyoulin/hookingo"
"net/http"
)
func main() {
hookingo.Apply(httpguts.IsTokenRune, func(r rune) bool {
fmt.Println("hookingo:", r)//没有打印输出
return true
})
req, err := http.NewRequest(`<custom-method>`, "http://127.0.0.1", nil)
}
//失败,其中 http.NewRequest内部调用了httpguts.IsTokenRune
golang 1.17 has introduced a significant changs on calling convention which make the lib does not work anymore.
