REST API、OAuth2和身份验证错误

Question

首先，感谢您的回复。我尝试使用nodeJS创建REST API，我认为oAuth2是根据我的系统对用户进行身份验证的最佳方式。

用户存储在LDAP中，api密钥保存在MySQL引擎上。客户帐户代码也将存储在MySQL中。所有过程都正常，用户已通过身份验证，API令牌已保存在MySQL中，但当我尝试使用此令牌时，passport拒绝对我的请求进行身份验证并返回：

Error: Can't set headers after they are sent.

    at ServerResponse.res.setHeader (/home/lolostates/Developpement/nodejs/oauth2/test/node_modules/express/node_modules/connect/lib/patch.js:62:20)

请求通过curl发送：

curl -H "Authorization: Bearer NoulKM889Aksf60rQONcUJwMuZHI3PDqzeXfkX3Li2BohsxNVsOrd2LLdvJAGZuE168IukUCPbviazhvBjt7VDfLFUMJRIY1fa95kGXQQKzE7etFhocsnYvbLSixbHRmCwXNx5FKj6v83Ci9f9xLqRinEKwaAUIjs03hhq8dCWIp7S0Cbi5jdkxlzwfpZxuShoAZYaFInlf4ymG5oyzQe0WJ2POXOaMarGLO7NkjyIMJXWh7s0Y" http://localhost:3000/api/userinfo

我使用passport-http-bearer、oAuth2orize和OAuth2orize示例中提供的所有示例函数。

你能给我解释一下为什么吗？

看起来您试图在响应发回后设置响应头。在尝试设置标头之前，请检查以确保未调用res.end() (或类似方法)。
