如何在python中从multifladict表中提取值

Question

我在命令提示符中接收到这个输出，我使用python flask打印它

ImmutableMultiDict([('{"amount":1000,"description":"test 
product","id":"tok_1BzM5eKliAs5iPakCZJ90MNY"}', '')])

我想从中提取金额，描述和身份 瓶中接收的代码

^{pr2}$

从我的前端我把它作为

onToken = (amount) => token => {

    token.amount = fromRupeeToPaise(amount);
    token.currency = localCurrency;     

    var requestOptions = {
      "method": "POST",
      "headers": {
          "Accept": "application/json",
          //"Content-Type": "application/json ; charset=utf-8"
          "Content-Type": "application/x-www-form-urlencoded; charset=utf-8"
      }
    };

    const toktest ={
        amount : 1000,
        description : "test product",
        id : token.id 
    }
    requestOptions["body"] = JSON.stringify(toktest);
    //requestOptions["body"] = JSON.stringify(token);
    fetch('http://localhost:5000/pay', requestOptions)

尝试在JSON中获取请求并使用'key'获取获取

例如：

data = request.get_json()
print data['amount']

或者：

^{pr2}$
