类型错误：字符串索引必须是整数，而使用 Gerrit rest API

Question

当我尝试通过 gerrit rest API 获取数据时，我收到了上面提到的错误。代码如下：from requests.auth import HTTPBasicAuth from pygerrit2.rest import GerritRestAPI import os auth = HTTPBasicAuth('user', 'pass') headers={'Content-Type': 'application/json; charset=UTF-8'} rest = GerritRestAPI(url='testgerriturl.com', auth = auth) changes = rest.get("changes/?q=all&o=DETAILED_ACCOUNTS&n=5", headers={'Content-Type': 'application/json'}) data={'status':[]}for change in changes:       for d in change:            data['status'].append(d[u'status'])我正在使用的 json 类型为：{ u 'status': u 'MERGED', u 'topic': u 'master_e', u 'updated': u '2018-09-04 05:40:19.000000000', u 'insertions': 549, u 'created ': u '2017-08-31 08:03:05.000000000', u 'change_id': u 'I7ed2f8da71e38f4908acf92f36dd', u 'hashtags': [], 'u:'18submitted' '18deletions 09-04 05:39:48.000000000', u 'submittable': False, u 'project': u 'testdemo', u 'branch': u 'master', u 'owner': { u 'username': u ' usertest', u 'email': u '[e-mail]', u 'name': u 'userdemo', u '_account_id': 36710 }, u '_number': 71090131, u 'id': u 'fm~master~I7ed71f4908acf92f36ddac3ff85b271e', u 'subject': u '%TBC FC: OSS_FC_0 App_NBI: RESTful Web Service Data Access API-PM Support : add IUM scripts' }我希望以以下形式输出：{'status': ['MERGED'], 'deletions': [178], 'updated': ['2018-09-03 20:58:26.000000000'], 'insertions': [664], 'created': [2018-08-28 08:16:56.000000000']}我在这里做错了，有人可以纠正我这里需要做什么吗？谢谢

Answer 1

这应该有帮助。

changes = { u'status': u'MERGED', u'topic': u'master_e', u'updated': u'2018-09-04 05:40:19.000000000', u'insertions': 549, u'created': u'2017-08-31 08:03:05.000000000', u'change_id': u'I7ed2f8da71e38f4908acf92f36dd', u'hashtags': [], u'deletions': 178, u'submitted': u'2018-09-04 05:39:48.000000000', u'submittable': False, u'project': u'testdemo', u'branch': u'master', u'owner': { u'username': u'usertest', u'email': u'[e-mail]', u'name': u'userdemo', u'_account_id': 36710 }, u'_number': 71090131, u'id': u'fm~master~I7ed71f4908acf92f36ddac3ff85b271e', u'subject': u'%TBC FC: OSS_FC_0 App_NBI: RESTful Web Service Data Access API- PM Support : add IUM scripts' }

data={'status':[], 'deletions':[], 'updated':[], 'insertions':[], 'created':[], }

for k, v in data.items():

    if k in changes:

        data[k].append(changes[k])

print(data)

输出：

{'status': [u'MERGED'], 'deletions': [178], 'updated': [u'2018-09-04 05:40:19.000000000'], 'insertions': [549], 'created': [u'2017-08-31 08:03:05.000000000']}
