我有一个包含以下数据的数据框：
email_addresses first_name last_name
0 [email protected] test test
1 [email protected] Jane Doe
2 [email protected] John Smith
我需要将以下格式的数据传递到常量联系人API的'data'参数中。格式需要像这样：
update_contact =
{
"import_data": [{
"email_addresses": ["[email protected]"],
"first_name": "test",
"last_name": "test"
}, {
"email_addresses": ["[email protected]"],
"first_name": "Jane",
"last_name": "Doe"
}, {
"email_addresses": ["[email protected]"],
"first_name": "John",
"last_name": "Smith"
}],
"lists": ["1"]
}
正如你所看到的，我需要在'import_data'周围传递字符串lists'和''lists_id'方括号。
我可以在将数据帧转换为json的同时传递字符串，如下所示：
update_contact = {"import_data" : update_contact.to_json(orient='records'), "lists" : 1}
但输出并不是我想要的。它是这样的：
{'import_data': '[{"\\ufeffemail_addresses":"[email protected]","first_name":"test","last_name":"test"},{"\\ufeffemail_addresses":"[email protected]","first_name":"Jane","last_name":"Doe"},{"\\ufeffemail_addresses":"[email protected]","first_name":"John","last_name":"Smith"}]',
'lists': 1}
我需要通过'update_contact'的API看起来像这样：
headers = {
'Authorization': 'Bearer x',
'X-Originating-Ip': 'x',
'Content-Type': 'application/json',
}
r = requests.post('https://api.constantcontact.com/v2/activities/addcontacts?api_key=x', headers=headers ,data = update_contact_now)
如何让to_json为我提供这样的JSON（数据帧中的100行）？ ：
update_contact =
{
"import_data": [{
"email_addresses": ["[email protected]"],
"first_name": "test",
"last_name": "test"
}, {
"email_addresses": ["[email protected]"],
"first_name": "Jane",
"last_name": "Doe"
}, {
"email_addresses": ["[email protected]"],
"first_name": "John",
"last_name": "Smith"
}],
"lists": ["1"]
}
编辑：
跑线：
update_contact = {"import_data" : update_contact.to_dict(orient='records'), "lists" : 1}
回：
{'import_data': [{'first_name': 'test',
'last_name': 'test',
'\xef\xbb\xbfemail_addresses': '[email protected]'},
{'first_name': 'Jane',
'last_name': 'Doe',
'\xef\xbb\xbfemail_addresses': '[email protected]'},
{'first_name': 'John',
'last_name': 'Smith',
'\xef\xbb\xbfemail_addresses': '[email protected]'}],
'lists': 1072830671}
Aaditi：
跑完线后：
df['email_addresses'] = df['email_addresses'].apply(lambda x: [x])
update_contact = {"import_data" : df.to_dict(orient='records'), "lists" : [1]}
print (update_contact)
我得到了结果：
{'import_data': [{u'email_address': '[email protected]',
u'first_name': u'bob',
u'last_name': u'bob'},
{u'email_address': '[email protected]',
u'first_name': u'tim',
u'last_name': u'joe'},
{u'email_address': '[email protected]',
u'first_name': u'sue1',
u'last_name': u'sue1'},
{u'email_address': '[email protected]',
u'first_name': u'tim3',
u'last_name': u'test'},
{u'email_address': '[email protected]',
u'first_name': u'Paul ',
u'last_name': u'Ryan'},
{u'email_address': 'TG_FN_121717@TG_LN_121717.com',
u'first_name': u'TG_FN_121717',
u'last_name': u'TG_LN_121717'},
{u'email_address': 'AS_FN_121717@AS_LN_121717.com',
u'first_name': u'AS_FN_121717',
u'last_name': u'AS_LN_121717'},
{u'email_address': '[email protected]',
u'first_name': u'Adam',
u'last_name': u'Apple'},
{u'email_address': '[email protected]',
u'first_name': u'Brenda',
u'last_name': u'Banana'},
{u'email_address': '[email protected]',
u'first_name': u'Charlene',
u'last_name': u'Cherry'},
{u'email_address': '[email protected]',
u'first_name': u'Donna',
u'last_name': u'Daquiri'}],
'lists': [1]}
不知道如何放弃'u'？
Aadita：
尝试：
a = json.dumps(update_contact)
得到了这个错误：

最终编辑：
这些代码行有效：
update_contact.rename(columns={'email_address': 'email_addresses'}, inplace=True)
df['email_addresses'] = df['email_addresses'].apply(lambda x: [x])
update_contact = {"import_data" : df.to_dict(orient='records'), "lists" : [1]}
a = json.dumps(update_contact,ensure_ascii=False)
print (update_contact)
我认为你需要to_dict字典，最后转换为json：
#remove \xef\xbb\xb
#https://github.com/pandas-dev/pandas/issues/4793
df = pd.read_csv(file, encoding="utf-8-sig")
#df.columns = df.columns.str.strip()
df['email_addresses'] = df['email_addresses'].apply(lambda x: [x])
update_contact = {"import_data" : df.to_dict(orient='records'), "lists" : [1]}
print (update_contact)
{'import_data': [{'email_addresses': ['[email protected]'],
'first_name': 'test',
'last_name': 'test'},
{'email_addresses': ['[email protected]'],
'first_name': 'Jane',
'last_name': 'Doe'},
{'email_addresses': ['[email protected]'],
'first_name': 'John',
'last_name': 'Smith'}],
'lists': [1]}
