go - panic : http: multiple registrations for/debug/requests

Question

我在我的 go 项目中出售了两个项目。我成功地编译了我的项目。当我运行我的项目时，它报告了错误 "panic: http: multiple registrations for/debug/requests"。详细错误如下所示。

goroutine 1 [running]:
net/http.(*ServeMux).Handle(0x19ae000, 0x126bb20, 0xf, 0x1964540, 0x1297d90)

有没有人知道如何修复它？我猜是因为我导入的两个项目都监听了/debug/requests?

Answer 1

我找到了原因。这是因为 golang.org/x/net/trace 项目。在它的 init() 函数中，它们使用硬代码处理 debug/request。因此，如果两个项目都导入该库，则会发生冲突。
