无法使用python读取json文件。获取类型错误：json对象为“ TextIOWrapper”
json.load()用于加载文件。json.loads()与字符串一起使用。@H_404_5@
我正在尝试从json文件读取。
这是我创建文件的方式：
import requests
import json
import time
from pprint import pprint
BASE_URL = "https://www.wikiart.org/en/api/2/UpdatedArtists"
artist_json_data = requests.get(BASE_URL).json()
with open('artistdata.json','w') as outfile:
while artist_json_data['hasMore']:
print(artist_json_data['paginationToken'])
url = BASE_URL + "?paginationToken=" +artist_json_data['paginationToken']
artist_json_data = requests.get(url).json()
json.dump(artist_json_data,outfile,indent=4)
time.sleep(1)
这是我输出的开始：
{
"data": [
{
"id": "57726da5edc2cb3880b4ca54","artistName": "Paul Feeley","url": "paul-feeley","lastNameFirst": "Feeley Paul","birthDay": "/Date(-1893456000000)/","deathDay": "/Date(-126230400000)/",当我尝试使用以下代码读取同一文件时：
from pprint import pprint
with open('artistdata.json','r',encoding='utf-8') as data_file:
data = json.loads(data_file)
pprint(data)
我得到错误
TypeError: the JSON object must be str,bytes or bytearray,not 'TextIOWrapper'
我不明白，因为我可以像往常一样崇高地打开文件。我该如何处理？
使用以下代码解决了该问题：
问题是我混合了转储和负载。现在我正在使用转储和加载
class Wikiart:
'''Class to access wikiart.org Data'''
def __init__(self):
self.BASE_URL = "https://www.wikiart.org/en/"
self.BASE_URL_API = self.BASE_URL + "api/2/"
self.BASE_URL_MOVEMENT = self.BASE_URL + 'artists-by-art-movement/'
self.ARTIST_DATA_URL = self.BASE_URL_API + "UpdatedArtists"
def write_artist_data_into_json_file(self):
artists = requests.get(ARTIST_DATA_URL).json()
all_artists = artists['data']
with open('artistdata.json','w') as outfile:
while artists['hasMore']:
print('fetching next: pagination token',artists['paginationToken'])
url = BASE_URL + "?paginationToken=" + artists['paginationToken']
artists_next_page = requests.get(url).json()
next_artists = artists_next_page['data']
time.sleep(0.25)
all_artists = all_artists + next_artists
artists = artists_next_page
json.dump(all_artists,indent=4)
from pprint import pprint
with open('artistdata.json',encoding='utf-8') as data_file:
data = json.load(data_file)
pprint(data)
