                        url: 'http://www.xjaft.com/api/v1/upload/img', //仅为示例，非真实的接口地址  
                        filePath: tempFilePaths[0],

                        success: uploadFileRes => {  
                            console.log(uploadFileRes.data);  
                        }  
                    });

后端代码

public static function uploadImg(){  
        $file = request()->file('image');  
        $info = $file->validate(['ext' => 'jpg,jpeg,png,gif'])->move('../public/uploads');  
        if ($info) {  
            $save_name = $info->getSaveName();  
            $param = Request::param();  
            $save_name = str_replace('\\', '/', $save_name);  
            $data = [  
                'img_url' => 'uploads/' . $save_name,  
                'type_id' => $param['need_id']+0,  
                'name' => $param['name']  
            ];  
            $res = Images::create($data);  
            if($res->isEmpty()){  
                throw new UploadException();  
            }  
            $data = $res->toArray();  
            return $data;  

        } else {  
            // 上传失败获取错误信息  
            throw new UploadException(['msg' => $file->getError()]);  
        }  
    }
