Question

我写的代码存在问题。当我运行代码时出现错误：

Traceback (most recent call last):
File "test23_json_users.py", line 23, in <module>
for user_dict in abc['user_account']['sip_id']:
TypeError: list indices must be integers, not str

代码：

result = '[{"user_account":[{"address":null,"name":null,"country":null,"password":"****","extension":"1112","sip_id":"23001@50.50.50.201","sip_name":"23001","user_id":7973712,"locked":false,"created":null,"h323_name":"1101","city":null,"email":null,"phone":null,"zip":null},{"address":null,"name":null,"country":null,"password":"****","extension":"1113","sip_id":"23002@50.50.50.201","sip_name":"23002","user_id":8847075,"locked":false,"created":null,"h323_name":"1102","city":null,"email":null,"phone":null,"zip":null},{"address":null,"name":null,"country":null,"password":"****","extension":"1114","sip_id":"23003@50.50.50.201","sip_name":"23003","user_id":3680630,"locked":false,"created":null,"h323_name":"1103","city":null,"email":null,"phone":null,"zip":null},{"address":null,"name":null,"country":null,"password":"****","extension":"1115","sip_id":"23004@50.50.50.201","sip_name":"23004","user_id":136391,"locked":false,"created":null,"h323_name":"1104","city":null,"email":null,"phone":null,"zip":null},{"address":null,"name":null,"country":null,"password":"****","extension":"1116","sip_id":"23005@50.50.50.201","sip_name":"23005","user_id":5692227,"locked":false,"created":null,"h323_name":"1105","city":null,"email":null,"phone":null,"zip":null},{"address":null,"name":null,"country":null,"password":"****","extension":"1117","sip_id":"23006@50.50.50.201","sip_name":"23006","user_id":7559026,"locked":false,"created":null,"h323_name":"1106","city":null,"email":null,"phone":null,"zip":null},{"address":null,"name":null,"country":null,"password":"****","extension":"1118","sip_id":"23007@50.50.50.201","sip_name":"23007","user_id":3226075,"locked":false,"created":null,"h323_name":"1107","city":null,"email":null,"phone":null,"zip":null},{"address":null,"name":null,"country":null,"password":"****","extension":"1119","sip_id":"23008@50.50.50.201","sip_name":"23008","user_id":6184875,"locked":false,"created":null,"h323_name":"1108","city":null,"email":null,"phone":null,"zip":null},{"address":null,"name":null,"country":null,"password":"****","extension":"1120","sip_id":"23009@50.50.50.201","sip_name":"23009","user_id":1711112,"locked":false,"created":null,"h323_name":"1109","city":null,"email":null,"phone":null,"zip":null},{"address":null,"name":null,"country":null,"password":"****","extension":"1121","sip_id":"23010@50.50.50.201","sip_name":"23010","user_id":5383101,"locked":false,"created":null,"h323_name":"1110","city":null,"email":null,"phone":null,"zip":null}]}'

params = result[result.find('{"'):]
#print params
abc = json.loads(params)

# Here I'm trying to extract just sip_id from the string result using json.
# I am not able to figure out what went wrong .
for user_dict in abc['user_account']['sip_id']:
    print  'usersname : %s' % (user_dict['sip_id'])

Answer 1

更改

for user_dict in abc['user_account']['sip_id']:

到

for user_dict in abc['user_account']:

Answer 2

abc['user_account']应该是一个列表。

列表a=['hello',1,2,'people']有4个元素，由索引a[0]到a[3]访问。

字典d={'a':1,'b':2}包含键和值。在这种情况下，d['a']的值为1，d[b']的值为2。

如果您想访问abc['user_account']中的内容，请输入abc['user_account'][42]。如果你想迭代它

for a in abc['user_account']:
  print a
