golang-Cookie cross-domain settings in gin (with Ajax)

This is a creation in Article, where the information may have evolved or changed.

1. When I use cookies in Golang, in the case of separation between the front and back ends, the cross-domain is not allowed. The code is as follows:

Func accessjsmiddleware () gin. Handlerfunc {   return func (c *gin. Context) {      W: = C.writer      //Handle Js-ajax cross-domain Problem      w.header (). Set ("Access-control-allow-origin", "*")//allows access to all domain      w.header (). Set ("Access-control-allow-methods", "Options, POST")      W.header (). ADD ("Access-control-allow-headers", "Content-type")      W.header (). ADD ("Access-control-allow-headers", "Access-token")      C.next ()   }}

1.1. This adds a cross-domain middleware at the start of the program, using the following

API: = Rounter. Group ("/api") API. Use (Accessjsmiddleware ())

The above settings are denied when Ajax requests to use cookies

2. Then I made a modification to solve the problem

2.1.ajax request to add a setting

Xhrfields: {withcredentials:true},

2.2. Then modified the settings for cross-domain middleware

Func accessjsmiddleware () gin. Handlerfunc {return func (c *gin. Context) {w: = c.writerr:=c.request//handles Js-ajax cross-domain problem W. Header (). Set ("Access-control-allow-credentials", "true") W.header (). Set ("Access-control-allow-origin", R.header.get ("Origin")) W.header (). Set ("Access-control-allow-methods", "Options, POST") W.header (). ADD ("Access-control-allow-headers", "Content-type") W.header (). ADD ("Access-control-allow-headers", "Access-token") C.next ()}}

The above solved the problem of cross-domain cookie, feel useful on the point of a recommendation and attention, after all, I am also a shy ⁄ (⁄⁄ ⁄ω⁄ ⁄⁄) ⁄ small public who.
