django - 使用 azuread-oauth2 时，exchange_access_token 上的 openEdx 服务器错误

Question

我现在正在部署 openEdx 系统，但在从移动设备通过 Azure AD 登录时遇到错误。

Web Azure AD 登录工作正常，我还可以从 azure ad 获取 access_token。

但是，当我尝试通过/oauth2/exchange_access_token/azuread-oauth2/url 与 openEdx token 交换 azure token 时，由于响应为空，我收到以下错误。

AttributeError:“NoneType”对象没有属性“get”

因此，我对 openEdx 相当陌生，我很难弄清楚如何解决这个问题。请帮助指导我找到解决此问题的正确路径。以下是详细的错误日志。

提前致谢

Answer 1

social-core 抛出错误，因为响应是 NoneType。由于您的目标是第三方 oAuth2，因此 social-core 在这里负责是有道理的。 如果它在网络上工作，那么只有当配置错误时，None 响应才可以解释。

现在，排除故障的步骤:

1. 检查 edx.properties 以确保配置目录设置正确。
2. 检查您的 config 和 local yaml 以确保 oauth 配置正确。 [而不是简单地配置 ios.yaml]
3. 确保您遵循提供的附加说明 here .
4. 如果其他方法都不起作用，请检查 social-auth 的配置，如所述 here .

希望有帮助!干杯!
