英文:
GET request instead of DELETE?
问题
使用下面显示的代码，我无法删除学生，因为当我点击删除按钮时，它会抛出“方法不允许”错误（状态=405）。
我发现很多人使用GET请求来管理这个，但这不是一个好的做法吗？我只想删除具有该ID的学生并保持在同一页（我会在修复此问题后稍后管理删除验证）。为什么相同的代码在GetMapping下工作而在DeleteMapping下不工作？
在studentController中
@DeleteMapping("/delete/{id}")
public String deleteStudent(@PathVariable Long id) {
this.studentService.deleteStudent(id);
return "redirect:/students";
}
在students.html中
<a th:href="@{'/students/delete/' + ${student.id}}" class="btn btn-danger">删除</a>
英文:
Using the code shown below, I can't delete a student because when I click the delete button, it throws a Method Not Allowed error (status=405)
I found out that many people use GET request instead of DELETE to manage this, but isn't it a bad practice? I just only want to delete the student with that id and stay at the same page (I'll manage delete validations later after I fix this). Why does the same code work with GetMapping but not with DeleteMapping?
In studentController
@DeleteMapping("/delete/{id}")
public String deleteStudent(@PathVariable Long id) {
this.studentService.deleteStudent(id);
return "redirect:/students";
}
In students.html
<a th:href="@{'/students/delete/' + ${student.id}}" class="btn btn-danger">Delete</a>

M. Deinum在评论中说，使用html <a href，你正在进行http GET请求。使用html form，你可以进行http GET或POST请求。所以在你的情况下，将@DeleteMapping("/delete/{id}")更改为@PostMapping("/delete/{id}")并使用html <form method="post"有一定道理。
如果你想使用http DELETE，你将需要使用javascript。
英文:
As M. Deinum said in comments, with html <a href you're doing http GET request. With html form you can do http GET or POST requests. So in your case changing @DeleteMapping("/delete/{id}") to @PostMapping("/delete/{id}") and using html <form method="post" kind of makes sense.
If you want to use http DELETE, you will have to use javascript.
