reactjs - 服务器重定向不适用于 ReactJS 代理服务器

Question

我在 React 前端使用代理服务器，在后端使用 Go 服务器。当我不使用 react 或代理服务器时，重定向工作正常。但是，当我使用 React 及其开发服务器和我的 Go 后端的代理时，重定向不会执行任何操作。

// React package.json file 
"proxy": "http://localhost:5000", // proxy to golang hosted on 5000
    "scripts": {
    "start": "react-scripts start",
},

-----------------------

// golang server

func main() {
    router := gin.Default()
    router.Use(static.Serve("/", static.LocalFile("../client/public", true)))
    ping := router.Group("/path") 
    ping.GET("/ping", pingFunc)
    ping.POST("/ping", pingFuncPost)
    router.Run(":5000")
}

// This redirect is not working.
// In the terminal it shows that a redirect is made but on the frontend
// nothing occurs

func pingFuncPost( c *gin.Context) 
{
    http.Redirect(c.Writer, c.Request, "/page", http.StatusSeeOther)`
}

你重定向，用

        const data = {"query": this.state.query};
        fetch(`/path/ping`, {  // should hit the end point of pingFuncPost in golang server, which should redirect to localhost:3000/results
            method: 'POST',
            body: JSON.stringify(data),
        })
.then(res => res.json())
.then(res => {
<Redirect to="/somewhere/else" />
})
