在我这里也是 fail的，跟踪了下发现是perform()执行，然后httptest server handler也被调用，但是这个时候回调函数没被执行。

[andelf]

怀疑是cgo回调go的时候阻塞了go的运行。考虑用别的方式搞搞。。。

[davecheney]

go-curl is broken under Go 1.1 because the function representation is now a two word structure, not just a straight pointer.

[anrope]

There was some discussion on #go-nuts irc, https://botbot.me/freenode/go-nuts/msg/4551111/, leading to a (temporary?) fix: http://pastie.org/8148641

I haven't tested to see if this breaks go 1.0 compatibility.

[andelf]

@anrope @davecheney thank you, I'll try fixing it.

[andelf]

fixed. now works.
