Gin-Gonic(golang)服务器上的Axios POST不起作用

I can use GET, but I cannot use POST from axios, sending data to my gin-gonic golang server. It works perfectly in Postman. When I shoot over the request with Axios, I get nothing in return.

When I go into the gin-gonic server, it shows that it returned a 500 error. Upon further inspection, I see that none of the post variables had been accessed by gin.

When I have used Postman, the server returns the array as specified. I have a feeling that it might have to do with headers, but I truly am stumped. I have encountered this problem about 6 months ago and never figured it out. Now I remember why I didn't continue with axios and nuxt :).

Here is the golang gin-gonic server route.

func initServer() {
    router := gin.Default()
    config := cors.DefaultConfig()
    config.AddAllowHeaders("*",)
    config.AllowAllOrigins = true
    config.AllowMethods = []string{"POST", "GET"}
    router.Use(cors.New(config))
    v1 := router.Group("/api/v1/stripe")
    {
        v1.POST("/pay", BuyProduct)
        v1.POST("/card", UpdateCard)
        v1.GET("/products", GetAllProducts)
        v1.GET("/products/id/:productId", GetProduct)
        v1.GET("/products/types/:typeId", GetProductType)
        v1.GET("/products/types", GetAllProductTypes)
    }

    // You can get individual args with normal indexing.
    serverAddress := "127.0.0.1:8080"
    if len(os.Args) > 1 {
        arg := os.Args[1]
        serverAddress = fmt.Sprintf("127.0.0.1:%v", arg)
    }

    router.Run(serverAddress)
}

Here is the receiver function that processes the router calls when the endpoint is hit

func BuyProduct(c *gin.Context) {

    postUserID := c.PostForm("userId")
    postProductId := c.PostForm("productId")
    token := c.PostForm("token")

    userId, err := strconv.Atoi(postUserID)
    if err != nil {
    panic(err)
    }
    productId, err := strconv.Atoi(postProductId)
    if err != nil {
        panic(err)
    }

    custy := user.InitCustomer(int64(userId), token)
    custy.GetStripeCustomerData()
    custy.SelectProduct(products.NewProduct(int64(productId)))
    custy.Purchase()

    c.JSON(200, gin.H{"status": 200,
        "product": custy.Product,
        "user": *custy.Saver.User,
        "subscriptions": *custy.Subscriptions,
        "ch": custy.Logs,
    })

    return
}

Here is my axios (nuxt) code.

async purchaseSubscription() {
    const paid = await 
    this.$axios.$post('http://localhost:8080/api/v1/stripe/pay', { data: { 
        userId: "121",
        productId: this.productId,
    }, query: {  } })
    this.paid = paid
},

Here is the error I get in the gin-gonic server in go
