Why is this Go-Lang IntelliJ plugin is inconsistent with Go's syntax?
问题
我对Go有点陌生，所以这可能是一个Go的问题，而不是IntelliJ的问题：我刚刚在IntelliJ 14中设置了https://github.com/go-lang-plugin-org/go-lang-idea-plugin/的zip文件。
我发现编译器与语法高亮器不一致。
以下代码会产生以下错误信息：
*not enough arguments in call to Redis.String.
仔细看一下对Redis.String的调用，它似乎接受一个interface+args。
因此，我可以通过在调用的末尾简单地添加一个"err"参数来欺骗IDE，以消除错误消息，如下所示：
world, err := redis.String(c.Do("GET", "message1"), err)
但是，这个"修复"会让Go编译器不高兴...它会报告以下消息（尽管IntelliJ插件不将其解释为错误）。
./t1.go:19: multiple-value c.Do() in single-value context
关于为什么IntelliJ Go插件需要两个参数，而GoLang只需要一个参数来调用此函数的想法将非常有帮助。

I'm somewhat new to Go, so this could be a Go problem, rather than an IntelliJ one: I've just set up https://github.com/go-lang-plugin-org/go-lang-idea-plugin/ from the zipfile, in IntelliJ 14.
I found that the compiler is inconsistent with the syntax highlighter.
world, err := redis.String(c.Do("GET", "message1"))
if err != nil {
fmt.Println("key not found")
}
Yields the following error message.
> *not enough arguments in call to Redis.String.
Looking closer at the call to Redis.String, it appears to take an interface+args.
func String(reply interface{}, err error) (string, error) {
....
return "", fmt.Errorf("redigo: unexpected type for String, got type %T", reply)
}
And thus, I'm able to trick the IDE into removing the rror message, by simply adding an "err" arg to the end of the call, like so:
world, err := redis.String(c.Do("GET", "message1"), err)
But Alas! This "fix" makes the go compiler unhappy... and it reports this message (even though the IntelliJ plugin does not interpret this as an error).
> ./t1.go:19: multiple-value c.Do() in single-value context
Any thoughts on why the IntelliJ Go Plugin wants two args, wheresas GoLang only wants one arg, for this function would be of great help.

这不是你犯的错误，只是我们目前在处理这个插件的特定部分时遇到的问题。
