gin跨域mile米乐体育的解决方案

cors1.go

packagemiddlewaresimport("github.com/gin-gonic/gin""net/http")funccors()gin.handlerfunc{returnfunc(c*gin.context){method:=c.request.methodorigin:=c.request.header.get("origin")iforigin!=""{c.header("access-control-allow-origin",origin)//主要设置access-control-allow-originc.header("access-control-allow-methods","post,get,options,put,delete,update")c.header("access-control-allow-headers","origin,x-requested-with,content-type,accept,authorization")c.header("access-control-expose-headers","content-length,access-control-allow-origin,access-control-allow-headers,cache-control,content-language,content-type")c.header("access-control-allow-credentials","false")c.set("content-type","application/json")}ifmethod=="options"{c.abortwithstatus(http.statusnocontent)}c.next()}}

cors2.go

funccors()gin.handlerfunc{returncors.new(cors.config{allowallorigins:false,alloworigins:nil,alloworiginfunc:func(originstring)bool{returntrue},allowmethods:[]string{"get","post","put","patch","delete","head"},allowheaders:[]string{"authorization","ts","accept","origin","dnt","x-customheader","keep-alive","user-agent","x-requested-with","if-modified-since","cache-control","content-type","content-range","range"},allowcredentials:true,maxage:10*time.minute,})}

使用中间件

packagerouterimport("github.com/gin-gonic/gin""goproejct/controllers""goproejct/middlewares"//引入中间件goproject是项目名根据自己情况)funcinitrouter(){router:=gin.default()router.use(cors())//使用中间件v1:=router.group("v1"){v1.post("/login",controllers.login)v1.post("/regist",controllers.regist)}router.run(":8000")}
