如果我不需要错误处理，如何将多值返回函数的结果用作Golang中另一个函数的参数？ [重复]

The following is what I want to achieve

fmt.Println(string(ioutil.ReadAll(res.Body)))

But this throws the following error.

multiple-value ioutil.ReadAll() in single-value context

I know that ioutil.ReadAll() returns the bytes and the error. But I don't want to write an extra line as follows

bytes, _ := ioutil.ReadAll(resp.Body)

Is it possible to just pass the result of ioutil.ReadAll() to fmt.Println() if don't care abut error handling in Go?

If you want it only once, it makes little sense in my opinion. However if this is a common situation and you feel that it improves code readability a lot, try something like:

// perhaps, there's a better name for this
func resultToString(b []byte, _ error) string { 
    return string(b)
}

// and later:
fmt.Println(resultToString(ioutil.ReadAll(res.Body)))

Unfortunately, that's a string-specific function, so for any other type you'll need to duplicate it.
