golang 预检请求错误
golang preflight request error
我已经使用 gorilla/mux
和 rs/cors
设置了我的 Go 后端。当我尝试发送包含自定义 header (Bearer
) 的请求时,它失败了。
我的服务器设置如下所示:
router := mux.NewRouter().StrictSlash(true)
router.HandleFunc("/users", GetUsers).Methods("GET")
router.HandleFunc("/", GetUsers).Methods("GET")
router.HandleFunc("/tweets", GetTweets).Methods("GET")
router.HandleFunc("/login", Login).Methods("POST")
router.HandleFunc("/profile/tweets", ProfileTweets).Methods("GET")
c := cors.New(cors.Options{
AllowedOrigins: []string{"*"},
AllowedMethods: []string{"GET", "POST", "PATCH"},
AllowedHeaders: []string{"Bearer", "Content_Type"},})
handler := c.Handler(router)
log.Fatal(http.ListenAndServe(":8080", handler))
我尝试了各种其他解决方案(例如在 Methods
调用中添加 OPTIONS
。
我试图为其传递 Bearer
令牌的端点是 /profile/tweets
端点。
我不确定如何继续 gorilla/mux
和 rs/cors
添加预检请求。
我得到的实际错误:
Fetch API cannot load http://localhost:8080/profile/tweets. Response
to preflight request doesn't pass access control check: No
'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'http://localhost:4200' is therefore not allowed
access. If an opaque response serves your needs, set the request's
mode to 'no-cors' to fetch the resource with CORS disabled.
谢谢!
我刚刚解决了这个问题。正如@Francois P.
所指出的,我在 AllowedHeaders
中有一个错字
此外,我必须添加 OptionsPassthrough
和 OPTIONS
方法,如下所示:
router.HandleFunc("/profile/tweets", ProfileTweets).Methods("GET","OPTIONS")
c := cors.New(cors.Options{
AllowedMethods: []string{"GET","POST", "OPTIONS"},
AllowedOrigins: []string{"*"},
AllowCredentials: true,
AllowedHeaders: []string{"Content-Type","Bearer","Bearer ","content-type","Origin","Accept"},
OptionsPassthrough: true,
})
