Laravel Vue.js API：axios的PUT方法不会向控制器发送任何数据

Question

我正在尝试使用Laravel和Vue.js中的API更新Model中的某些数据 但我无法执行此操作，因为axios不会将任何数据发送到服务器，我正在发送之前检查数据，并且它们存在（我使用FormData.append添加所有字段）

我在使用代码发送之前检查数据：

for(var pair of formData.entries()) {
   console.log(pair[0]+ ': '+ pair[1]); 
} 

，我得到以下结果：

您可以检查适当的代码： [更新功能]     updateStartup（）{

            let formData = new FormData();
            formData.append('startup_logo', this.update_startup.startup_logo);
            formData.append('country_id', this.update_startup.country_id);
            formData.append('category_id', this.update_startup.category_id);
            formData.append('startup_name', this.update_startup.startup_name);
            formData.append('startup_url', this.update_startup.startup_url);
            formData.append('startup_bg_color', this.update_startup.startup_bg_color);
            formData.append('startup_description', this.update_startup.startup_description);
            formData.append('startup_public', this.update_startup.startup_public);

            axios.put('/api/startup/' + this.update_startup.id, formData, { headers: {
                    'Content-Type': 'multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW',
                }
            })
                .then(function (response) {
                    console.log(response);
                })
                .catch(function (error) {
                    console.log(error.response);
                });

        }

[我应该在其中接收数据的控制器方法]：

 public function update(Request $request, $id) {

    return $request; // just for checking if I get data
    ...
 }

[带有vue.js的HTML，我使用在updateStartup函数中发送的对象]：

[其他信息-同样，当我打开模式（我有要更新的表单的地方）时，我也会根据启动ID更改表单数据]：

showUpdateStartup(startup) {

            setTimeout(() => {
                $('.selectpicker').selectpicker('refresh');
            }, 50);

            this.update_startup.id = startup.id;
            this.update_startup.category_id = startup.category.id;
            this.update_startup.category_name = startup.category.name;
            this.update_startup.startup_name = startup.name;
            this.update_startup.startup_description = startup.description;
            this.update_startup.startup_url = startup.url;
            this.update_startup.startup_logo = startup.logo;
            this.update_startup.startup_bg_color = startup.startup_bg_color;
            this.update_startup.contact_id = startup.contact.id;
            this.update_startup.contact_name = startup.contact.name;
            this.update_startup.contact_phone = startup.contact.phone;
            this.update_startup.contact_email = startup.contact.email;
            this.update_startup.country_id = startup.contact.country.id;
            this.update_startup.country_flag = startup.contact.country.flag;
            this.update_startup.country_name = startup.contact.country.name;
            this.update_startup.is_admin = startup.contact.is_admin;
            this.update_startup.startup_public = startup.public;
        },

如果您还有其他疑问，请告诉我

非常感谢你们的帮助和想法！

Answer 1

尝试通过axios.post方法使用formData.append('_method', 'PATCH')。

Answer 2

从控制器返回输入数据而不是Request对象：

return $request->input();
