Question

下面是JSON文件的内容，我怎么才能得到第二级的密钥，这意味着我应该能够存储像uid，passid，signbuttonid，logoIcon，cornerSettingMenu，logoutButtonId，overlayId，loaderInFunctionalPanel这样的密钥。我应该能够使用python存储在列表或某个数组中。意味着我需要像

list[0]=  uid

list[1]=passid

list[2]=  signbuttonid

list[3]=logoIcon and so on . . . . . .

{ “GlobalElements”： [ { “UID”： “USEREMAIL” “passid”： “userPwd” “signbuttonid”：“//按钮[@ class ='btn btn-mammoth']”， “logoIcon”：“// a [@ class ='logo text-hide']”， “cornerSettingMenu”： “// DIV [@类= '下拉肘节'] / P”， “logoutButtonId”： “//一个[@类= '注销']”， “overlayId”： “// DIV [@类= '覆盖']”， “loaderInFunctionalPanel”：“// DIV [@类= '小直列装载机'] /子:: I [@类='发 fa-spinner fa-pulse']“ } ]

注意：我不需要那些值。我只需要钥匙。

任何人都可以帮我这个。提前致谢。

Answer 1

如果

import json

a={ "GlobalElements" :[ { "uid":"userEmail", "passid":"userPwd", "signbuttonid": "//button[@class='btn btn-mammoth']", "logoIcon":"//a[@class='logo text-hide']", "cornerSettingMenu":"//div[@class='dropdown-toggle']/p", "logoutButtonId":"//a[@class='logout']", "overlayId":"//div[@class='overlay']", "loaderInFunctionalPanel":"//div[@class='small-inline-loader']/child::i[@class='fa fa-spinner fa-pulse']" } ]}

a= json.dumps(a) #serialize dictionary to json

b=json.loads(a)  #unserialize json to get dictionary

获取密钥列表：

l= b["GlobalElements"][0].keys()
print l

[u＆＃39; uid＆＃39;，u＆＃39; logoutButtonId＆＃39;，u＆＃39; logoIcon＆＃39;，u＆＃39; signbuttonid＆＃39;，u＆＃39; passid＆＃39;，u＆＃39; overlayId＆＃39;，u＆＃39; loaderInFunctionalPanel＆＃39;，u＆＃39; cornerSettingMenu＆＃39;]

首先你需要导入json 将您的json内容存储在变量中。如果它在文件中，请读取文件并将其存储在变量中。使用dumps（）和loads（）方法来序列化和反序列化，并将值取为如下代码

import json

x={ "GlobalElements" :[ { "uid":"userEmail", "passid":"userPwd", "signbuttonid": "//button[@class='some id']", "logoIcon":"//a[@class='some id']", "cornerSettingMenu":"//div[@class='dropdown-toggle']/p", "logoutButtonId":"//a[@class='logout']", "overlayId":"//div[@class='overlay']", "loaderInFunctionalPanel":"//div[@class='small-inline-loader']/child::i[@class='fa fa-spinner fa-pulse']" }  ] }

x= json.dumps(x)

y=json.loads(y)
z= b["GlobalElements"][0].keys()

此处z将保留第二级的第一个值。

如何使用python获取JSON的二级密钥？
