php - Ajax 数据未发送到控制器功能（Laravel）

问题描述

我将iddom 元素作为ajax数据发送到 laravel 控制器，但Request控制器端的对象为空。我已返回自定义数组以ajax检查控制器功能是否正常工作，并且它正在返回对ajax成功的响应。

同一控制器上的其他函数从但不是这个函数获取Request数据。ajax我没有收到任何错误，因此很难调试问题

我的阿贾克斯电话

$(document).on('click', 'i[id^="delete"]', function () {

        var alias_id = $(this).prop('id');
        //console.log(alias_id);

        $.ajax({
            headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            },
            url: "{{ route('deletealiasname') }}",
            method: "post",
            data: {'alias_id': alias_id},
            dataType: "json",
            contentType: false,
            cache: false,
            processData: false,
            beforeSend : function()
            {
                console.log(alias_id);
            },
            success: function (response) {
                console.log(response);
            }
        });
    });

路线：

Route::post('/deletealiasname', 'API\UserProfileController@deleteAliasName')->name('deletealiasname');

控制器：

public function deleteAliasName(Request $request)
{
    $var = $request->all();
    return array($var);
}

dd($request) 的输出

    POST http://127.0.0.1:8000/api/deletealiasname

解决方案

我想问题出在method:"post"

因为它不是method对象，它实际上是一个type.

type:"post"

试试这个

$.ajax({
            headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            },
            url: "{{ route('deletealiasname') }}",
            type: "post",
            data: {'alias_id': alias_id},
            dataType: "json",
            contentType: false,
            cache: false,
            processData: false,
            beforeSend : function()
            {
                console.log(alias_id);
            },
            success: function (response) {
                console.log(response);
            }
        });

正如你所说，你正在使用laravel 5.8. 因此您可以在终端中启动转储服务器进行调试。jsut在终端中点击命令php artisan dump-server和dd(#request)

看看数据是否到来。

我确定它的问题在于method:"post"只需将其更改为type:"post"
