python - 通过 Python 脚本/代码获取特定的 dict 值

问题描述

我正在通过 Python 执行 RESTAPI 调用，并在执行 json.loads 调用后以 dict 格式获取值。

挑战是，我想获取以下值：

a）“校验和”：“f9676703bba1f3ac726de1445de27726”

b) 'zone-name': 'Axel_Rodge_SPA' （输出中所有可用的区域名称）

我尝试了很多通过 .get() 方法获取的方法，但并没有太大帮助。此外，它不是正确的 dict 数据类型，这是另一个挑战。任何建议将不胜感激。

global switch_config_backup_json
call_config_backup = ""
try:
    switch_config_url = 'http://' + ipaddress + '/rest/running/brocade-zone/effective-configuration'
    switch_config_backup_call_headers = {'Authorization': custom_api_key, 'Accept': 'application/yang-data+json', 'Content-Type': 'application/yang-data+json'}
    call_config_backup = requests.get(url=switch_config_url, headers=switch_config_backup_call_headers)
    switch_config_backup_dict = json.loads(call_config_backup.content)
    print("Switch zone and members data backup:\n", switch_config_backup_dict)

检索到的值：（字典类型）

解决方案

你有dictionary，list所以你需要for-loop （或索引 ie. [0]）来获取值。

而且因为您已经嵌套dictionares，所以您将不得不使用所有键来获取嵌套值。

#print('[DEBUG] type:', type(data) )
#print('[DEBUG] keys:', data.keys() )

#print('[DEBUG] type:', type(data['Response']) )
#print('[DEBUG] keys:', data['Response'].keys() )

#print('[DEBUG] type:', type(data['Response']['effective-configuration']) )
#print('[DEBUG] keys:', data['Response']['effective-configuration'].keys() )

checksum = data['Response']['effective-configuration']['checksum']
print('checksum:', checksum)

zones = data['Response']['effective-configuration']['enabled-zone']
print('type:', type(zones))

for item in zones:
    print('zone-name:', item['zone-name'])

结果：

checksum: f9676703bba1f3ac726de1445de27726
type: <class 'list'>
zone-name: Axel_Dellpr740A
zone-name: Axel_Dellpr740C
zone-name: Axel_Rodge_SPA
zone-name: Axel_Rodge_SPA_Test
zone-name: Axel_Rodge_SPB
zone-name: Rodge-Dellpr730H
zone-name: Rodge_Dellpr730E
zone-name: dellpr730B_Marge

顺便提一句：

您可以使用json.dumps(..., indent=...)缩进对其进行格式化，以更好地查看JSON.

如果你看到{...}那么它是 (nested) dictionary，如果你看到[...]那么它是 (nested) list。

您还可以使用type(item)来测试您是否有（嵌套）dictionary或list.
并且dictionary您可以使用item.keys()来查看您可以在此级别上使用的键。
