How do I pass a parameter in a string in thymeleaf

Question

I am trying to delete an item on a list by passing the task ID in an a href link in thymeleaf. This is what it looks like

<a th:href="@{'delete-task?id='${task.id}}"> 

But instead of deleting the item this is the output

delete-task?id=th:text=%27${task.id}%27

Im getting this error in the slack trace

 : Error parsing HTTP request header
 Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.

java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986
Can anyone tell me the correct syntax

Answer 1

You should be using thymeleaf's Standard URL Syntax for links -- so that parameters can be correctly url escaped. Your link should look like this:

<a th:href="@{delete-task(id=${task.id})}">

Answer 2

我相信您的href应该看起来像这样：

<a th:href="@{'delete-task?id=' + ${task.id}}"></a>
