解析 Python JSON

Question

我正在尝试解析下面的 JSON，并从元素中提取名称和间隔。

reply "[ {
  "interface" : [ {
    "name" : "ethernet39",
    "number" : 39,
    "rate" : [ {
      "interval" : 45,
      "rx-bad-vlan-rate" : 0,
      "rx-broadcast-packet-rate" : 0,
      "rx-byte-rate" : 0,
      "rx-drop-rate" : 0,
      "rx-error-rate" : 0,
      "rx-multicast-packet-rate" : 0,
      "rx-unicast-packet-rate" : 0,
      "timestamp" : "2015-06-18T21:59:23.703Z",
      "tx-broadcast-packet-rate" : 0,
      "tx-byte-rate" : 0,
      "tx-drop-rate" : 0,
      "tx-error-rate" : 0,
      "tx-multicast-packet-rate" : 0,
      "tx-unicast-packet-rate" : 0
    }, {
      "interval" : 45,
      "rx-bad-vlan-rate" : 0,
      "rx-broadcast-packet-rate" : 0,
      "rx-byte-rate" : 0,
      "rx-drop-rate" : 0
...

我尝试了以下方法：

  for x in range(0,len(interfaces)):
    for interface in interfaces[x]:
      entry = {}
      entry['name'] = statistic['name']
      for interval in statistic['rate']:
        entry['byte_rate'] = interval['rx-byte-rate']
        entry['packet_rate'] = interval['rx-unicast-packet-rate']
        entry['timestamp'] = interval['timestamp']
        entry['droprate'] = interval['rx-drop-rate']
        entry['errorrate'] = interval['rx-error-rate']
    entries.append(entry)

但是，我总是收到一个错误 TypeError: 字符串索引必须是整数

我做错了什么？代码中interfaces是通过json.load()获取的JSON

Answer 1

“interface”和“rates”字典值是列表，因此您需要对它们进行索引。

print("name = {}".format(reply["interface"][0]["name"]))
rates = reply["interface"][0]["rate"]
for rates_index in range(len(rates)):
    print("rate = {}".format(rates[rates_index]["interval"]))

Answer 2

不应该是界面而不是统计吗？？

for x in range(0,len(interfaces)):
    for interface in interfaces[x]:
      entry = {}
      entry['name'] = interface['name']
      for interval in interface['rate']:
        entry['byte_rate'] = interval['rx-b
