Question

python新手，尝试将json文件转换为csv并编写下面的代码，但不断收到“TypeError：string indices必须是整数”错误。请建议。

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"]
                ])

以下是示例1行输入json文件数据：

{"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"}}]}

据我所知，问题在这里

for x in x:

请注意，代码中的x是dict，而不是list。我认为（根据提供的json示例）你需要像

这样的东西

for x in x['issues']:

另外，@ Reti43在评论中注明，dicts中x['issues']的键在不同元素之间有所不同。为了使您的代码更安全，您可以使用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")
                ])

错误：TypeError：字符串索引必须是整数
