重新装机后，项目突然出来错误，无法登陆，点击登陆无法提交到后端，后端无反应，控制台提示：
Access to XMLHttpRequest at 'http://127.0.0.1:8000/api/getUserType' from origin 'http://127.0.0.1:5173' has been blocked by CORS policy: Request header field task-access-token is not allowed by Access-Control-Allow-Headers in preflight response.
The error message you're encountering is a Cross-Origin Resource Sharing (CORS) issue. CORS is a security feature implemented by web browsers to restrict access to resources from different domains. When your JavaScript code running on one origin tries to make an XMLHttpRequest to a different origin, the browser sends a preflight request (OPTIONS method) to check if the server allows such requests.
但是我已经把cors配置成app.use(cors()) ，没有任何限制，还是出错，重启电脑可以偶尔解决，困扰了我一周多的时间，有次，打开微信，项目突然出错，我意识到是不是微信的问题，我把微信关了，项目立马正常，再打开微信，再出错，再关掉，立马好，我找到原因了，是因为微信版本过低，导致的这个问题，想不明白，为什么微信能导致我的项目跨域问题，有大佬能解释下吗？
