如何在 Python Azure Function 中传递不同的 HttpResponses？

Question

我正在尝试根据整个 HTTP 触发的检查，Python Azure 函数，找到 returning 不同 HttpResponse 的模式。

示例：

import azure.functions as func


def main(req: func.HttpRequest) -> func.HttpResponse:

    logging.info('####### HTTPS trigger processing an event... #######')

    def get_request_headers():
        thing_id = req.headers.get("thing-id")
        req_host_ip = req.headers.get("X-FORWARDED-FOR")

        return thing_id, req_host_ip


    def check_thing_id_hdr(thing_id):
        if (
            thing_id != None
            and thing_id.isnumeric() == True
            and len(thing_id) == 20
        ):
            return True
        else:
            # DO I RETURN THE HTTPRESPONSE HERE?
            return func.HttpResponse(
                'Thing ID header is malformed',
                status_code = 404
            )

    def check_req_host_ip_hdr(req_host_ip):
        if (
            req_host_ip.split(':')[0] != None
        ):
            return True
        else:
            # DO I RETURN THE HTTPRESPONSE HERE?
            return func.HttpResponse(
                'Host IP header is malformed',
                status_code = 404
            )

    request_headers = get_request_headers()

    if(check_thing_id_hdr(request_headers[0]) == True:
        check_req_host_ip_hdr(request_headers[1])
    else:
        logging.error('####### Thing ID header failed check. #######')
        # OR DO I DEFINE THE HTTPRESPONSE HERE? 
        func.HttpResponse(
            'Thing ID header is malformed',
            status_code = 404
        )

# OR DO I SOMEHOW DEFINE THE CUSTOM RESPONSE HERE?
return func.HttpResponse(
        'Custom Message HERE',
        status_code = Custom Status Code HERE
    )

我已经尝试了上述模式以及用大 try:-except: 包装所有内部函数，但其中 none return 自定义消息。

请指教

下面的代码是你想要的吗？

import logging

import azure.functions as func


def main(req: func.HttpRequest) -> func.HttpResponse:

    #For example, use the param as the condition.
    condition = req.params.get('condition')
    if condition == "success":
        return func.HttpResponse(
             "Success.",
             status_code=200
        )
    elif condition == "not_success":
        return func.HttpResponse(
             "Not success.",
             status_code=400
        )
    else:
        return func.HttpResponse(
             "No condition.",
             status_code=404
        )
