python-3.x - Python 中另一个 API 请求（相同 API）中的 API 请求

问题描述

我目前制作了一个 python 程序，从 API 请求 JSON 数据。虽然这个 JSON 实际上包含其他请求 Url 以从该对象获取额外数据，但现在这就是问题所在。

import requests

import json

import sys

import os

import geojson



response = requests.get("http://api.gipod.vlaanderen.be/ws/v1/workassignment", params = {"CRS": "Lambert72"})

print(response.status_code)
text = json.dumps(response.json(),sort_keys=True, indent=4)
print(text)

f = open("text.json", "wt")
f.write(text)

print(os.getcwd())

来自请求的 JSON，包括参数在内的其他请求 URL 在详细信息列中。

"cities": ["Leuven"]**
}
],
"latestUpdate": "2016-11-16T11:32:39.253"
}

第一个请求只获取点（每个点都有特定的 id），而第二个请求获取“详细数据”，其中还包含多边形数据和多线数据。

现在这是交易，必须为我从第一个 API 请求中获得的每个对象重复此请求。这可以是一百多个对象。所以逻辑规定这必须在一个循环中发生，尽管如何开始有点..麻烦。

解决方案

在这种情况下，您可以使用功能。

您的第一个函数可以简单地获取点列表。您的第二个功能可以简单地获取详细信息的数据。


def fetch_details(url: str):
      """ Makes request call to get the data of detail """
        response = requests.get(url)
        # any other processe


def fetch_points(url: str):
       
       response = requests.get(url)
       for obj in response.json():
              fetch_details(obj.get("detail"))

api_url = "api.gipod.vlaanderen.be/ws/v1/workassignment"
fetch_points(api_url)
