Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

說明

在使用 axios 進行 ajax 請求時，發生跨域錯誤。后端使用 SpringBoot，已經加上 @CrossOrigin 注解

原因

瀏覽器的預檢請求失敗，即 OPTION 請求失敗，根據你的后端放行 OPTION 請求即可

解決方案

// Spring Security 中放行 option 請求
.requestMatchers(CorsUtils::isPreFlightRequest).permitAll()

其他后端自行查詢如何放行 OPTION 請求即可
