Azure 函数:返回 JSON 对象 [英] Azure functions: return JSON object

问题描述

考虑:

import logging
import azure.functions as func

def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = {"test":"jjj"}
    return func.HttpResponse(name)

以上是我使用 Python 预览的 Azure 函数 (V2).

Above is my Azure function (V2) using Python preview.

如果我回来

func.HttpResponse(f"{name}")

它有效，但如果我返回一个 dict 对象，它就不会.

it works, but if I return a dict object it does not.

显示的错误是:

Exception: TypeError: reponse is expected to be an str, bytes, or bytearray, got dict

Exception: TypeError: reponse is expected to be either of str, bytes, or bytearray, got dict

推荐答案

您需要使用内置 JSON 库将您的字典转换为 JSON 字符串 - json.dumps.

You need to convert your dictionary to a JSON string using the built-in JSON library - json.dumps.

然后您可以将函数的 MIME 类型(Content-Type)设置为应用程序/json.默认情况下 Azure 函数 HttpResponse 返回 text/plain 内容类型.

Then you can set the MIME type (Content-Type) of your function to application/json. By default Azure functions HttpResponse returns text/plain Content-Type.

import json
import logging
import azure.functions as func

def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = {"test":"jjj"}
    return func.HttpResponse(
        json.dumps(name),
        mimetype="application/json",
    )
