只能将 str（不是 "NoneType"）连接到 str

Question

获取 api 响应文本并在 python3

中打印时遇到问题

response = session.get(url=url, headers=headers, json=payload, verify=cabundle,
                               auth=auth)
        if response.status_code == 200:
            print(response.status_code)
            print("Response is:")
            data = json.loads(response.text)
            print(data)
            if data['issues']!= []:
                issueId = data['issues'][0]['id']
                print("Issue ID :    " +issueId)

输出：

200
Response is:
Expecting value: line 3 column 1 (char 4)
can only concatenate str (not "NoneType") to str

谁能帮忙解决这个问题？

Answer 1

连接前检查 issueId 是否存在:

issueId = data['issues'][0]['id']
if issueId:
    print("Issue ID : " + issueId)

Answer 2

使用字符串参数，如果是none类型，它会插入None。

print(f"Issue Id: {issueId}")

只能将 str（不是 "NoneType"）连接到 str
