我开发一个H5网站，支付成功返回的url是
https://xxxx.com/mobile%2Fpages%2Fgoods_order%2Fgoods_order%3FbuyGoods%3D%5B%7B%22goodsId%22%3A2%2C%22skuId%22%3A2%2C%22num%22%3A1%2C%22cartId%22%3A0%7D%5D%26order_id%3D287%26from%3Dorder%26checkPay%3Dtrue

把这个url解码就是原地址

这个buyGoods参数就是个Json数据，

然后支付成功之后跳转之后发现url变成https://xxxx.com/mobile/pages/goods_order/goods_order?buyGoods=[{goodsId:2,skuId:2,num:1,cartId:0}]&order_id=287&from=order&checkPay=true

双引号全部没有了，这个是什么情况？
