|| 操作员未按预期工作

Question

What is going wrong here? I am 100% sure I am sending a HTTP POST request, but somehow the OR operator is not working as I am expecting. In the first example the server returns a 405 and in the second example the code continues executing.

not working:

if req.Method != http.MethodPost || req.Method != http.MethodDelete {
    http.Error(res, http.StatusText(http.StatusMethodNotAllowed), http.StatusMethodNotAllowed)
    return
}

working:

if req.Method != http.MethodPost {
    http.Error(res, http.StatusText(http.StatusMethodNotAllowed), http.StatusMethodNotAllowed)
    return
}

Answer 1

(Not something) OR (not something else mutually exclusive) is always going to be true isn't it?

If it is method post, it will not be delete and vice versa , you might want && ?
