Laravel 5 如何在axios请求中使用Maatwebsite\Excel下载csv文件？

在laravel 5.8/axios“^0.18”、“vue”：“^2.5.17”应用程序中，我使用Maatwebsite\Excel上载csv文件 如果我在GET请求中运行laravel控件，它就会起作用， 但我使用axios进行post请求，运行请求时根本不会下载文件。 我在JS代码中运行我的请求：

        axios({
            method: ( 'post' ),
            url: this.$store.getters.apiUrl + '/personal/run-user-list-export-to-csv',
            data: { user_id : user_id, user_list_id: user_list_id },
        }).then((response) => {
            this.showPopupMessage("User list export", "User list successfully exported !", 'success');
        }).catch((error) => {
            this.showPopupMessage("User list export", 'Error exporting user\'s list !', 'error');
        });

控制：

public function run_user_list_export_to_csv() // http://127.0.0.1:8000/api/run-user-list-export-to-csv
{
    $request= request();
    ...

    $ret= \Excel::download(new exportSearchResults($user_list_id), 'file.csv');  // if write RETURN this line file is not downloaded anyway...
    return response()->json( ['error_code' => 1, 'message' => '', 'ret' => $ret, HTTP_RESPONSE_INTERNAL_SERVER_ERROR ] );
} // public function storerun_user_list_export_to_csv(UserLisRequest $request)

我看到输出后浏览器的响应：

{"error_code":1,"message":"","ret":{"headers":{}},"0":500}

[2019-06-14 04:46:23] local.INFO: HTTP/1.0 200 OK
Cache-Control:       public
Content-Disposition: attachment; filename="aaa Z3  iuy65 .csv"
Date:                Fri, 14 Jun 2019 04:46:23 GMT
Last-Modified:       Fri, 14 Jun 2019 04:46:23 GMT

但文件并没有下载。正确程度如何

已修改： 我尝试在我的控制操作中通过发送标题进行重拍，如：

public function run_user_list_export_to_csv() 
{
    $request= request();
    ...
    $filename= $title.'.csv';
    $download_path= $filename;
    $ret= \Excel::download(new exportSearchResults($user_list_id), $download_path);
    \Log::info($ret);
    $headers = ['Content-Type: application/csv','Content-Disposition: attachment; filename={$filename}'];

    return response($download_path, 200,$headers);
} // public function storerun_user_list_export_to_csv(UserLisRequest $request)

我在日志文件输出中看到：

{"error_code":1,"message":"","ret":{"headers":{}},"0":500}

[2019-06-14 04:46:23] local.INFO: HTTP/1.0 200 OK
Cache-Control:       public
Content-Disposition: attachment; filename="aaa Z3  iuy65 .csv"
Date:                Fri, 14 Jun 2019 04:46:23 GMT
Last-Modified:       Fri, 14 Jun 2019 04:46:23 GMT

但没有下载任何文件。 哪条路对

修改2: 1） 我生成了csv文件，但在浏览器的下载方法中下载失败。我似乎更喜欢这种方式。 但我可以将生成的csv文件移动到某个目录（比如/home/user/）并在客户端的csv应用程序中打开它

2） 如何使用vue js定义当前用户的名称及其下载目录（请记住，客户端可能有不同的操作系统）

修改3:

我找到了这个插件并尝试安装它

我试着用这把小提琴， 但我的文件中引用了错误：

app.js?dt=1560770053:2823 Uncaught ReferenceError: VueCSV is not defined
    at Module../node_modules/babel-loader/lib/index.js?!./node_modules/vue-loader/lib/index.js?!./resources/js/components/Horizontal/personal/userLists/list.vue?

在/Horizontal/personal/userLists/list.vue中：

<script>
    ... 
    import Vue from 'vue';
    Vue.component("csv-download", VueCSV.CsvDownload)

如果我将导入行修改为：

    import VueCSV from 'vuecsv';    // /node_modules/vuecsv/dist/vuecsv.min.js
I see error in npm console : 
This dependency was not found:

* Vue in ./node_modules/vuecsv/dist/vuecsv.min.js

To install it, you can run: npm install --save Vue

当然我已经安装了vue

哪条路是对的？

难道这个插件不工作？您能提出类似建议吗？

使用axios上传文件：

const config = {
   headers: {
              "content-type": "multipart/form-data",
              "Access-Control-Allow-Origin": "*"
            }
   };
axios.post(ROOT+'/image/upload',data,config);

您的laravel路线：

Route::post('/image/upload','API\ImageController@upload');

您的ImageController：

public function upload(Request  $request)
{
    $file = $request->file('image');

---

要使用axios上载文件，请执行以下操作：

const config = {
   headers: {
              "content-type": "multipart/form-data",
              "Access-Control-Allow-Origin": "*"
            }
   };
axios.post(ROOT+'/image/upload',data,config);

您的laravel路线：

Route::post('/image/upload','API\ImageController@upload');

您的ImageController：

public function upload(Request  $request)
{
    $file = $request->file('image');
