【报Bug】uni.uploadFile使用files上传文件，文件参数丢失

示例代码：

function chooseAvatar() {  
    uni.chooseImage({  
        count: 1, //默认9  
        sizeType: ['original', 'compressed'], //可以指定是原图还是压缩图，默认二者都有  
        sourceType: ['album'], //从相册选择  
        success: res => {  
            iconFile.value = res.tempFiles[0]  
        }  
    });  
}  

function chooseBackground() {  
    uni.chooseImage({  
        count: 1, //默认9  
        sizeType: ['original', 'compressed'], //可以指定是原图还是压缩图，默认二者都有  
        sourceType: ['album'], //从相册选择  
        success: res => {  
            backgroundFile.value = res.tempFiles[0]  
        }  
    });  
}  

const iconFile = ref<any>()  
const backgroundFile = ref<any>()  
const circleInfo = ref<CircleParam>({  
    description: "默认圈子",  
    title: "默认圈子",  
    parentId: "11111"  
})  

function sub() {  
    if (!hasToken()) {  
        // token无效  
        uni.navigateTo({  
            url: '/pages/auth/auth'  
        })  
        return  
    }  
    createCircle(circleInfo.value, [iconFile, backgroundFile]).then(res => {  
        toast("申请圈子分类成功,等待管理员审核")  
    })  
}  

export function createCircle(data: any, files: any[]) {  
  // 用户添加二级分类发送请求  
  return postForm("/circle/create", data, files);  
}  

export const postForm = (url: string, formData: AnyObject, files: any): Promise<Result> => {

      success: (res: UploadFileSuccessCallbackResult) => {

    }  

操作步骤：

获取到文件之后 调用postForm 方法

预期结果：

后端可以获取到文件名称

实际结果：

获取到的信息全是错误的
