javascript - 我在 Laravel5.4 中的 DELETE Ajax 请求上收到 405(方法不允许)错误

Question

我是 Laravel 新手。

我想通过 ajax 调用从数据库表中删除一条记录，但出现以下错误。

DELETE http://192.168.33.10/staff/4/edit 405 (Method Not Allowed) onDeleteButtonClick @ d2d.js:75

我正在 JavaScript 代码中向“http://192.168.33.10/staff/4”发送 ajax 请求，但该请求似乎发送到“http://192.168.33.10/staff/4/edit”。

如何向“http://192.168.33.10/staff/4”发出ajax请求？

HTML 表单 http://192.168.33.10/staff/4/edit

<form method="post" action="http://192.168.33.10/staff/{{  $staff->id  }}">

    <div class="form-group row">
        <div class="col-6">
            <label for="">last name</label>
            <input type="text" class="form-control" id="" name="last_name" placeholder="" value="{{  $staff->last_name }}">
        </div>

        <div class="col-6">
            <label for="">first name</label>
            <input type="text" class="form-control" id="" name="first_name" placeholder="" value="{{  $staff->first_name }}">
        </div>

    </div>

    <button type="submit" class="btn btn-primary">update</button>
    {{ method_field('PUT') }}


    <button id="delete-button" type="button" class="btn btn-danger">delete</button>

    <input id="hidden-value" type="hidden" name="id" value="{{  $staff->id  }}"/>
    {{ csrf_field() }}


</form>

JavaScript

var $deleteButton = document.getElementById("delete-button");

$deleteButton.addEventListener("click", onDeleteButtonClick);

function onDeleteButtonClick(event) {


    var request = new XMLHttpRequest();

    request.ontimeout = function(event){
        console.log("timeout error");
    };

    request.onreadystatechange = function() {


        if(request.readyState === 4) {

            console.log("done");

            if(request.state === 0) {

                console.log("fail");

            } else {

                if(request.status === 200) {

                    console.log("request success");
                    location.href = "http://192.168.33.10/staff";

                } else {

                    console.log("request fail");



                }

            }

        }

    };

    request.onload = function(event) {
        console.log("onload");
        console.log(request.response);

    };

    request.onerror = function(event) {
        console.log("onerror");
        console.log(request.response);

        console.log(request.responseText);

    };

    var id = document.getElementsByName("id")[0].value;
    var token = document.getElementsByName("_token")[0].value;

    var url = "http://192.168.33.10/staff/" + id;


    request.open("DELETE", url, true);

    request.responseType = "json";
    request.timeout = 2000;

    request.setRequestHeader('content-type', 'application/x-www-form-urlencoded;charset=UTF-8');

    request.send('id=' + encodeURIComponent(id) + '&' + '_token=' + encodeURIComponent(token));

}

员工 Controller

class StaffController extends Controller
{

    //other methods here...

    //delete
    public function destroy($id, StaffRequest $request) {

        $staff = Staff::findOrFail($id);
        $staff->delete();

        return response()->json(['apple' => 'red', 'peach' => 'pink']);

    }


}

更新

request.setRequestHeader('XSRF-TOKEN', token);
//request.setRequestHeader('X-CSRF-TOKEN', token);
request.send('id=' + encodeURIComponent(id));
// request.send('id=' + encodeURIComponent(id) + '&' + '_token=' + encodeURIComponent(token));

我像上面一样更改了 JavaScript 代码中的两行，因此现在我向“http://192.168.33.10/staff/4 ”发出 DELETE 请求。

但是我收到 500 错误而不是 405 错误。

删除链接中的编辑参数DELETE http://192.168.33.10/staff/4/edit成为DELETE http://192.168.33.10/staff/4
