我正在尝试使用API后端设置React身份验证。 API后端使用电子邮件和密码,并且还为每个新用户创建令牌。所有这些都是通过直接JSON而不是JWT提供的,所以我使用Auth0 tut和Stack q/a作为起点。
我的第一个目标是进行简单的登录和重定向。我把动作/缩减器连接起来,我现在正在进行API调用。我正在使用基本的auth调用并将其转换为64位字符并通过标头发送。这些都是通过Postman测试和工作的。
当我执行当前的React设置时,它会在控制台中显示“Fetching”,但从不“我在这里。”,页面只是重新加载。我不知道在哪里解决这个并获得它授权和重定向。我出错的任何想法?

答案 0 :(得分:1)
尝试使用return fetch('http://api.xxx.dev/sessions'...
。
没有经过测试,但它应该让你“我在这里”。
最后,包装箭头函数{}
