Question

根据存储的Cookie（selectedRetailerId）中的特定值，源（API端点）不同。

我试图将cookie的值存储在名为retailer_id的变量中，并使用它来确保调用正确的端点。

这是我正在尝试的...

<OTHER CODE IS REDACTED>

ReactDOM.render(
  function getCookie(name) {
    var value = "; " + document.cookie;
    var parts = value.split("; " + name + "=");
    if (parts.length == 2) return parts.pop().split(";").shift();
  }

  var retailer_id = getCookie(selectedRetailerId);

  <DeliveryOptionsTable source="http://<REDACTED>/delivery_options/{retailer_id}" />,
  document.getElementById('deliveryOptionsContainer')
)

但是这会返回一个Uncaught SyntaxError。可能是因为这段代码不应该在ReactDOM.render中。

Uncaught SyntaxError: http://localhost:8000/src/app.js: Unexpected token (130:2)
  128 |   }
  129 | 
> 130 |   var retailer_id = getCookie(selectedRetailerId);
      |   ^
  131 | 
  132 |   <DeliveryOptionsTable source="http://<REDACTED>/delivery_options/{retailer_id}" />,
  133 |   document.getElementById('deliveryOptionsContainer')

使用React执行此操作的正确方法是什么？

试试这个：

// Defined somewhere outside ReactDOM.render (I'd recommend a helpers.js file)
// If you move it out of this file, be sure to import / require it
function getCookie(name) {
  var value = "; " + document.cookie;
  var parts = value.split("; " + name + "=");
  if (parts.length == 2) return parts.pop().split(";").shift();
}

ReactDOM.render(
  <DeliveryOptionsTable source={"http://<REDACTED>/delivery_options/" + getCookie(selectedRetailerId)} />,
  document.getElementById('deliveryOptionsContainer')
)

道具值基于存储的cookie
