我有一個非常簡單的帶有 CORS 中間件的應用程序，它似乎可以正常工作并且預檢請求按預期工作。但由于某種原因，服務器根據實際請求以 307 響應。在瀏覽器中重現，來自 postman works correclty。func main() {    router := gin.Default()    router.Use(CORSMiddleware())    accountsGroup := router.Group("/accounts")    accountsGroup.POST("/", postAccount)    router.Run("localhost:8080")}func CORSMiddleware() gin.HandlerFunc {    return func(c *gin.Context) {    c.Header("Access-Control-Allow-Origin", "*")    c.Header("Access-Control-Allow-Credentials", "true")    c.Header("Access-Control-Allow-Headers", "Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization, accept, origin, Cache-Control, X-Requested-With")    c.Header("Access-Control-Allow-Methods", "POST,HEAD,PATCH, OPTIONS, GET, PUT")    if c.Request.Method == "OPTIONS" {        c.AbortWithStatus(204)        return    }    c.Next()}func postAccount(c *gin.Context) {    response := gin.H{"id": 1}    c.IndentedJSON(http.StatusCreated, response)}飛行前反應實際要求
