錯誤：TypeError：字符串索引必須為整數

Question

python的新手，嘗試將json文件轉換為csv並編寫了以下代碼，但始終收到“ TypeError：字符串索引必須為整數”錯誤。 請提出建議。

import json
import csv

#x= '''open("Test_JIRA.json","r")'''
#x = json.load(x)

with open('Test_JIRA.json') as jsonfile:
    x = json.load(jsonfile)

f = csv.writer(open("test.csv", "w"))

# Write CSV Header, If you dont need that, remove this line
f.writerow(["id", "self", "key", "customfield_12608", "customfield_12607"])

for x in x:
    f.writerow([x["id"],
                x["self"],
                x["key"],
                x["fields"]["customfield_12608"],
                x["fields"]["customfield_12607"]
                ])

這是示例1行輸入json文件數據：

{"expand":"schema,names","startAt":0,"maxResults":50,"total":100,"issues":[{"expand":"operations,versionedRepresentations,editmeta,changelog,renderedFields","id":"883568","self":"https://jira.xyz.com/rest/api/2/issue/223568","key":"AI-243","fields":{"customfield_22608":null,"customfield_12637":"2017-10-12T21:46:00.000-0700"}}]}

Answer 1

據我所知問題在這里

for x in x:

請注意，代碼中的x是dict ，不是list 。 我認為（基於提供的json示例），您需要類似

for x in x['issues']:

另外，@ Reti43在注釋中指出， x['issues']的dicts鍵在元素之間有所不同。 為了使您的代碼更安全，可以使用get

for x in x['issues']:
    f.writerow([x.get("id"),
                x.get("self"),
                x.get("key"),
                x.get("fields", {}).get("customfield_12608"),
                x.get("fields", {}).get("customfield_12607")
                ])
