Python请求-动态传递HTTP动词 [英] Python Requests - Dynamically Pass HTTP Verb

问题描述

是否有一种方法可以将HTTP动词(PATCH/POST)传递给函数，并动态地将该动词用于Python请求?

Is there a way to pass an HTTP verb (PATCH/POST) to a function and dynamically use that verb for Python requests?

例如，我希望此函数采用一个动词"变量，该变量只能在内部调用，并且可以是= post/patch.

For example, I want this function to take a 'verb' variable which is only called internally and will either = post/patch.

def dnsChange(self, zID, verb):
    for record in config.NEW_DNS:
        ### LINE BELOW IS ALL THAT MATTERS TO THIS QUESTION 
        json = requests.verb(headers=self.auth, url=self.API + '/zones/' + str(zID) + '/dns_records', data={"type":record[0], "name":record[1], "content":record[2]})
        key = record[0] + "record with host " + record[1]
        result = json.loads(json.text)
        self.apiSuccess(result,key,value)

我意识到我不能像上面那样请求动词"，这是为了说明问题.有办法做到这一点或类似的方法吗?我想避免:

I realize I cannot requests.'verb' as I have above, it's meant to illustrate the question. Is there a way to do this or something similar? I'd like to avoid an:

if verb == 'post':
    json = requests.post(headers=self.auth, url=self.API + '/zones/' + str(zID) + '/dns_records', data={"type":record[0], "name":record[1], "content":record[2]}
else:
    json = requests.patch(headers=self.auth, url=self.API + '/zones/' + str(zID) + '/dns_records', data={"type":record[0], "name":record[1], "content":record[2]}

谢谢大家！

推荐答案

对于请求库， requests.request 方法(如Guillaume的答案所示).

With the request library, the requests.request method can be relied on directly (as Guillaume's answer suggested).

但是，当遇到不具有通用方法的库(具有相似的调用签名的方法)时，可以为getattr提供所需方法的名称，并将其作为具有默认值的字符串.也许像

However, when encountering against libraries that don't have a generic method for methods that have similar calling signatures, getattr can be supplied with the name of the desired method as a string with a default value. Maybe like

action = getattr(requests, verb, None)
if action:
    action(headers=self.auth, url=self.API + '/zones/' + str(zID) + '/dns_records', data={"type":record[0], "name":record[1], "content":record[2]})
else:
    # handle invalid action as the default value was returned

对于默认值，它可以是一个适当的操作，或者只是将其省略而将引发异常；由您决定如何处理.我将其保留为None，因此您可以在else部分中处理其他情况.

For the default value it can be a proper action, or just leave it out and an exception will be raised; it's up to you how you want to handle it. I left it as None so you can deal with alternative case in the else section.
