我需要阅读的 json 文件是什么？

Question

enter image description here我需要使用python下载卫星图像。我在 GitHub 中找到了一个代码，但我不明白这一行是什么。请帮我看看它到底是什么。 访问https://github.com/kscottz/PythonFromSpace/blob/master/TheBasics.ipynb

import sys
import os
import json
import scipy
import urllib
import datetime 
import urllib3
import rasterio
import subprocess
import numpy as np
import pandas as pd
import seaborn as sns
from osgeo import gdal
from planet import api
from planet.api import filters
from traitlets import link
import rasterio.tools.mask as rio_mask
from shapely.geometry import mapping, shape
from IPython.display import display, Image, HTML
import matplotlib.pyplot as plt
import matplotlib.image as mpimg
urllib3.disable_warnings()
from ipyleaflet import (
    Map,
    Marker,
    TileLayer, ImageOverlay,
    Polyline, Polygon, Rectangle, Circle, CircleMarker,
    GeoJSON,
    DrawControl
)

%matplotlib inline
# will pick up api_key via environment variable PL_API_KEY
# but can be specified using `api_key` named argument
api_keys = json.load(open("apikeys.json",'r'))
client = api.ClientV1(api_key=api_keys["PLANET_API_KEY"])
# Make a slippy map to get GeoJSON

api_keys = json.load(open("apikeys.json",'r')) 
client = api.ClientV1(api_key=api_keys["PLANET_API_KEY"])

这两行是什么意思。我应该为 apikeys.json 上传什么文件

Answer 1

您应该点击此链接获取 API 密钥。 https://support.planet.com/hc/en-us/articles/212318178-What-is-my-API-key-

apikeys.json 是 json 中以下格式/内容的 JSON 文件：

{"PLANET_API_KEY":"<Some API Key here>"}

json.load(...) API 将此 json 文件加载为字典
