无法从 Flutter 调用 Odoo Api

Question

我使用 Controller 在 Odoo 中创建了一个 API。身份验证类型是 public，因此无需身份验证即可访问此 API。当我在 Postman 或任何浏览器中调用此 API 时，我没有问题。但是当我在 Flutter 中访问这个 API 时，我得到了一个错误。

这是 Flutter 代码

var response = await Dio().get('https://my-odoo-domain.com/api/sales');
print(response);

这是错误信息

Error: DioError [DioErrorType.response]: XMLHttpRequest error.

如何解决这个问题？

更新

我在 Web 平台上运行时出现此错误，但在 Mobile 上运行时出现此错误& Desktop 平台我没有错误。我认为问题出在安全性或类似 CORS

Answer 1

问题出在 CORS 上。我需要通过在端点传递 CORS 参数来启用 CORS

@http.route('/my/route', auth='public' ,cors='*')  
def my_route(self):
