无法在开发模式下启动Plaid quickstart应用程序

Question

我刚开始用格子呢。我已经在本地设置了quickstart应用程序，它在沙盒模式下运行良好。链接面板加载良好，我可以使用沙箱creds登录机构

我的.env文件如下所示：

PLAID_CLIENT_ID=xxxxxxxx
PLAID_SECRET=xxxxxxxx
PLAID_ENV=sandbox
PLAID_PRODUCTS=transactions
PLAID_COUNTRY_CODES=US,CA
PLAID_REDIRECT_URI=http://localhost:3000

我现在想检查Plaid是否能与一些特定的真实/实时机构合作，所以我正在尝试更新我的quickstart应用程序，使其在开发模式下工作。为此，我只需将PLAID_SECRET更新为我的开发密钥，将PLAID_ENV更新为“development”

当我现在启动应用程序时，开始页面不再显示“启动链接”按钮，而是显示：

日志表明问题发生在POST/api/create\u link\u令牌调用上。如果我从该路由功能中删除错误处理，日志会显示问题：

Reason: Bad Request

HTTP response body: {
  "display_message": null,

  "error_type": "INVALID_INPUT",
  "request_id": "EbCTgZkFdeYQQ8r",
  "suggested_action": null
}

这表明我使用了错误的客户id或密码，但我不明白。客户端ID应该很好（它在沙盒模式下工作），这个秘密绝对是我开发模式的秘密（我甚至尝试过生成一个新的，但没有区别）。我错过什么了吗

最后，如果我使用Postman发布到https://development.plaid.com/link/token/create来创建一个链接令牌，使用相同的客户端ID和“开发”秘密，它似乎工作得很好（即，我得到了200个响应和全新的链接令牌）

非常感谢您的帮助

Answer 1

哎呀，这样就可以了：

https://github.com/plaid/quickstart/blob/master/python/server.py#L84

看起来python快速启动是硬编码的，忽略了.env文件中设置的环境变量。我们会把它修好的。同时，改变这条线应该可以解决你的问题

Answer 2

这是因为Python是硬编码到沙箱的。正在修复此问题，同时，在server.py的第84行，您可以将其更改为：

“host=plaid.Environment.Development”
