Question

我无法获得＆＃34; remoteAddress＆＃34;只有在我需要的时候。此输出由另一个API生成，因此我无法对其进行编辑。为了清楚起见，我想分割2个过程的数据。对不起，如果它是重新发布，我找不到类似的帖子。

  Select inv.InvoiceNo, inv.EntryDateTime, s.ServiceName, c.VehicleRegNo, inv.ServicePrice, c.CustomerName, inv.fk_BookingID
    from dbo.[Services] s
    inner join invoices inv
    on inv.fk_ServiceID= s.ServiceID
    inner join customers c
    on c.CustomerID= inv.fk_CustomerID
    Cross join (Select SUM(inc.ServicePrice) as TotalCost from dbo.Invoices inc ) t
    where Convert(varchar(11), inv.EntryDateTime, 106) between @FromDate and @ToDate

编辑：它需要是动态的，所以我不能只搜索＆＃34; remoteAddress＆＃34;。我正在解析GRR流，不同的流具有可能丢失的不同密钥。

Answer 1

使用dict.get

<强>实施例

data = [{
   "family": "INET6",
   "pid": 835,
   "localAddress": {
       "ip": "127.0.0.1",
       "port": 44082
   },
   "processName": "avahi-daemon",
   "state": "NONE",
   "type": "SOCK_DGRAM"
},
{
   "family": "INET",
   "pid": 22624,
   "localAddress": {
       "ip": "0.0.0.0",
       "port": 631
   },
   "remoteAddress": {
       "ip": "x.x.x.x",
       "port": 443
   },
   "processName": "gitkraken",
   "state": "ESTABLISHED",
   "type": "SOCK_STREAM"
 }
]
res = [i.get("remoteAddress") for i in data]
print(res)
print(filter(None, res))

<强>输出：

[None, {'ip': 'x.x.x.x', 'port': 443}]
[{'ip': 'x.x.x.x', 'port': 443}]

Answer 2

假设这两个词典存储在列表中，例如

data = [{
   "family": "INET6",
   "pid": 835,
   "localAddress": {
       "ip": "127.0.0.1",
       "port": 44082
   },
   "processName": "avahi-daemon",
   "state": "NONE",
   "type": "SOCK_DGRAM"
},
{
   "family": "INET",
   "pid": 22624,
   "localAddress": {
       "ip": "0.0.0.0",
       "port": 631
   },
   "remoteAddress": {
       "ip": "x.x.x.x",
       "port": 443
   },
   "processName": "gitkraken",
   "state": "ESTABLISHED",
   "type": "SOCK_STREAM"
 }]

然后此代码应返回“远程地址”中存储的值

for dictionary in data:
    if "remoteAddress" in dictionary:
        print(dictionary.get("remoteAddress"))
