无法将JSON代码的输出打印到.csv文件中

标签： json python-2.7 csv parsing web-scraping

尝试解码此数据时出现以下错误，并尝试补偿unicode错误后出现第二个错误：

错误1：

write.writerows(subjects)
UnicodeEncodeError: 'ascii' codec can't encode character u'\u201c' in position 160: ordinal not in range(128)

错误2：

with open("data.csv", encode="utf-8", "w",) as writeFile:
SyntaxError: non-keyword arg after keyword arg

代码

import requests
import json
import csv
from bs4 import BeautifulSoup
import urllib

r    = urllib.urlopen('https://thisiscriminal.com/wp-json/criminal/v1/episodes?posts=10000&page=1')
data = json.loads(r.read().decode('utf-8'))

subjects = []

for post in data['posts']:
subjects.append([post['title'], post['episodeNumber'], 
post['audioSource'], post['image']['large'], post['excerpt']['long']])

with open("data.csv", encode="utf-8", "w",) as writeFile:
write = csv.writer(writeFile)
write.writerows(subjects)

答案 0 :(得分：1)

使用请求并更正第二部分（如下所示），我运行没有问题。我认为您的第一个问题是由于第二个错误（是由于不正确造成的）。

我使用的是Python3，可以使用我的修复程序打开行并使用

我个人会使用r = urllib.request.urlopen('https://thisiscriminal.com/wp-json/criminal/v1/episodes?posts=10000&page=1') 。

requests

第二步，查看import requests import csv data = requests.get('https://thisiscriminal.com/wp-json/criminal/v1/episodes?posts=10000&page=1').json() subjects = [] for post in data['posts']: subjects.append([post['title'], post['episodeNumber'], post['audioSource'], post['image']['large'], post['excerpt']['long']]) with open("data.csv", encoding ="utf-8", mode = "w",) as writeFile: write = csv.writer(writeFile) write.writerows(subjects) 函数的documentation，您需要使用正确的参数名称，如果位置不匹配，则需要添加open参数的名称。
