Php 参数1传入Laravel错误。我不知道'；我不知道如何解决这个错误

我目前正在使用语言检测和语言翻译API。但是，这个函数在所有控制器上都能很好地工作，但是请求ajax，它的错误与标题相同

ajax

$("#translationBtn").click(function(){
    $.ajax({
        url: '{{route('translation')}}',
        type: 'post',
        data: {_token: "{{ csrf_token() }}",
                'material': $('#translationBox').val(),
            },
        success: function (data) {

            alert(data);

        }, error: function () {
            alert("error!!!!");
        }
    });
});

控制器 控制器检查通过ajax接收的值

<?php

namespace App\Http\Controllers\Home;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Http\Controllers\Helper\Translation;

class TranslationController extends Controller
{
    use Translation;

    public function translation(Request $request){

       return $this->translation($request->material,$this>langCode($request->material));

    }
}

您正在中使用函数名
翻译
Class TranslationController
和
Trait Translation
。一个是
静态
，另一个是
实例
。
调用
实例
方法而不是
静态
。
最好使用不同的名称以避免混淆

您当前的代码正在执行递归，而不是使用trait方法

将trait方法重命名为其他方法并尝试。
问题是什么？错误消息似乎解释了这个问题，控制器类中的转换方法要求第一个参数的类型为
illighted\Http\Request
。修复方法是传递预期对象，否？
返回$this->translation（$request->material，$this>langCode（$request->material））是错误的
translation
是一个静态函数，您可能会因为使用trait而感到困惑，并且在控制器和控制器使用的trait中具有相同的方法名称。如@Jonnix所说，这可能是由于您的控制器方法名和trait方法名相同所致。实际上，您是在用相同的方法调用
TranslationController:：translation（）
。在我的方法名称中，我也会使用动词而不是名词。你错过了这么一件小事！非常感谢。多亏了我的朋友，我觉得自己长大了！
