我试图从这里开始遵循 Plaid 的文档,但我似乎无法弄清楚public_token当我在 Plaid开发环境中工作时从哪里获得。他们是这样说的:
在他们的第二个例子中:
from plaid import Client
client = Client(client_id='***', secret='***', public_key='***', environment='sandbox')
# the public token is received from Plaid Link
response = client.Item.public_token.exchange(public_token)
access_token = response['access_token']

我不知道从哪里来的public_token。如果我去那个格子链接他们说:
此存储库现已弃用。要与 Plaid 集成,请访问文档。https://plaid.com/docs
然后,当我去他们的官方文档时,我似乎找不到任何方法来获得它public token。
我正在尝试按照以下方式做一些事情:

InvalidPlaidEnvironment,
MissingPlaidCredential

VALID_ENVIRONMENTS = (

在文档中,他们还指定了以下内容:
A
public_token(在您的 LinkonSuccess()回调中返回)应该传递给您的服务器,服务器会将其交换为access_token. public_tokens 是一次性使用的令牌,30 分钟后过期。您可以根据需要通过 /item/public_token/create 端点生成新的 public_token。An
access_token用于访问项目的产品数据。这应该安全地存储,并且永远不要存储在客户端代码中。这用于为用户向 Plaid API 发出经过身份验证的请求。默认情况下,access_tokens 不会过期,但您可以轮换它们;如果它最终处于错误状态,并且项目的错误得到解决,则 access_token 将再次工作。每个 access_token 对特定 Item 是唯一的,不能用于访问其他 Item。
但这更令人困惑。任何人都可以给我一些关于这方面的建议吗?

基本上public_token来自客户端意味着
当您为该 Plaid 实现前端部分/客户端以链接或创建项目时,创建public_token 的后端 流程是该链接(官方文档);根据公共令牌生成的onSuccess文档;
并且该公共令牌将发送到此处的服务器端/后端部分,您可以根据要求使用该公共令牌:
如下:
from plaid import Client
client = Client(client_id='***', secret='***', public_key='***', environment='sandbox')
# the public token is received from Plaid Link
response = client.Item.public_token.exchange(public_token)
access_token = response['access_token']
