我正在将dom元素的id作为ajax数据发送到laravel控制器，但是Request对象在控制器端为空。我已将自定义数组返回到ajax，以检查控制器功能是否正常工作，并返回对ajax成功的响应。
同一控制器上的其他功能从Request获取ajax数据，但不是此功能。我没有收到任何错误，因此很难调试问题
我的Ajax呼叫
$(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

我想问题出在method:"post"
因为它不是method对象，所以实际上是type。
type:"post"
尝试这个
$.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);
}
});
与您所说的一样，您正在使用laravel 5.8。因此您可以在终端中启动转储服务器以进行调试。终端php artisan dump-server和dd(#request)中的jsut hit命令
看看是否有数据。
确定问题出在method:"post"上，只需用type:"post"进行更改
答案 1 :(得分：0)
我不知道为什么会发生这种情况，但是找到了一种通过ajax发送数据的方法。我只是添加了一个form元素，然后将数据附加到FormData并将其作为ajax数据发送。
表单元素
<form id="deleteAliasName" class="ui form" action="{{ route('deletealiasname') }}" method="post">
</form>
Ajax
var alias_id = $(this).attr('data-id');
formData = new FormData($('#deleteAliasName')[0]);
formData.append('alias_id', alias_id);
$.ajax({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
url: "{{ route('deletealiasname') }}",
type: "post",
data: formData,
dataType: "json",
contentType: false,
cache: false,
processData: false,
success: function (response) {
console.log(response);
}
});
现在我在控制器请求中接收到数据
我不会将其标记为可接受的答案，因为我认为这是一种解决方法。
