清除值JSON

Question

我在返回JSON时遇到了一个错误，显然是因为字典的“0”，但是字典有这样的结构，我想有办法删除“0”，我留下下面的代码来了解这是否可行

d = json.loads('{ "jsonrpc": "2.0", "id": "1", "result": [ 0, {"ubus_rpc_session": "d8f4cec54d08c3f1d5581ec6135992e7","timeout": 300,"expires": 300,"acls": {"access-group": {"superuser": ["read","write"],"unauthenticated": ["read"]},"ubus": {"*": ["*"],"session": ["access","login"]},"uci": {"*": ["read","write"]}},"data": {"username": "root"}}]}')

#print d

for i in d["result"]:

    if 'ubus_rpc_session' in i:
        print i['ubus_rpc_session']
```

if 'ubus_rpc_session' in i:
TypeError: argument of type 'int' is not iterable

Answer 1

检查下面的代码，它是用python编写的，因此print还有其他语法

import json
d = json.loads('{ "jsonrpc": "2.0", "id": "1", "result": [ 0, {"ubus_rpc_session": "d8f4cec54d08c3f1d5581ec6135992e7","timeout": 300,"expires": 300,"acls": {"access-group": {"superuser": ["read","write"],"unauthenticated": ["read"]},"ubus": {"*": ["*"],"session": ["access","login"]},"uci": {"*": ["read","write"]}},"data": {"username": "root"}}]}')

#print d
#print(type(d['result'][1]))

i = d['result'][1]['ubus_rpc_session']
print(i)

Answer 2

出现错误，因为键'result'的值是一个列表，而“ubus\u rpc\u session”是列表字典中的一个键。简单地说，该值类似于[int，dict]

所以d['result']给出[int，dict..] 在第一次迭代中，您正在检查“ubus\u rpc\u session”是否为int，这是错误的（因此是TypeError）。一个可能的解决方法是，删除int并只获取dict元素

value_dict = d.get("results")[1] #dict is at index 1 in the value of 'results' key
if 'ubus_rpc_session' in value_dict:
....#Do Something
