【问题描述】：

我正在尝试使用 Mailchimp API 的批处理功能。我现在的设置是这样的

operations = []
for idx, row in users_df.iterows():
    payload = {
        'email': row['email'],
        'last_updated': row['new_time'],
        'custom_value': row['new_value']
    }
    operation_item = {
        "method": "POST", # I changed this to PUT
        "path": '/lists/members/12345',
        "body": json.dumps(payload),
    }
    operations.append(operation_item)
client = mc.MailChimp(MAILCHIMP_TOKEN, MAILCHIMP_USER)
batch = client.batches.create(data={"operations": operations})

每当我使用 POST 方法时，我都会收到此错误：old_user@gmail.com is already a list member. Use PUT to insert or update list members.

但每当我将方法更改为 PUT 时，我都会收到另一个错误：The requested method and resource are not compatible. See the Allow header for this resource's available methods.

有没有办法克服这个问题？我已经看过this 和this 是Ruby 中的类似问题。

【解决方案1】：

您不能对列表资源"/lists/members/12345" 执行 PUT，您需要将路径更改为 "/lists/members/12345/{email}"

此代码适用于我们：

def add_users_to_mailchimp_list(list_id, users):
operations = []
client = get_mailchimp_client()

for user in users:
    member = {
        'email_address': user.email,
        'status_if_new': 'subscribed',
        'merge_fields': {
            'FNAME': user.first_name or '',
            'LNAME': user.last_name or '',
        },
    }
    operation_item = {
        "method": "PUT",
        "path": client.lists.members._build_path(list_id, 'members', user.email),
        "body": json.dumps(member),
    }
    operations.append(operation_item)
return client.batches.create(data={"operations": operations})

使用受保护的方法client.lists.members._build_path 我想有点hacky，如果你喜欢你可以手动构建url，它将是f'lists/{list_id}/members/{user.email}'
