Axios POST请求和PHP $ _FILES

我正在研究API，我必须在 PHP server 上发送POST请求才能上传文件 .

目前， php server 查看 $_FILES 是否为空

这是我的查询在我的API中的样子：

var bodyFormData = new FormData();  
for (var file in parameters.files) {  
    bodyFormData.append('file',  fs.createReadStream('uploads/'+parameters.files[file].name));
}
//console.dir(bodyFormData);
var methodToken = response.data.methodToken;
var configUploadFiles = {
    url: '/upload/',
    method: 'post',
    baseURL: 'http://192.168.170.52',
    headers: {'Content-Type': 'multipart/form-data', 'userToken': userToken, 'methodToken': methodToken},
    data: bodyFormData
}

axios.request(configUploadFiles)
.then(response => {
    // Do somethink
})
.catch(error => {
    // Do otherthink
});

查询运行正常，这是 FormData 的 console.log ：

FormData {
    _overheadLength: 317,
    _valueLength: 0,
    _valuesToMeasure: 
         [ ReadStream {
             _readableState: [Object],
             readable: true,

             [Function: bound ] ],

             _boundary: '--------------------------246027426731056834535848' }

问题是在处理 POST 时，在 PHP 的服务器上，变量 $_FILES 是 empty

当我 error_log $_FILES : Array\n(\n)\n

我必须绝对经历这个变量，因为要做出太多改变
