uni.uploadFile 上传多文件的相关问题

app 使用 uni.uploadFile 上传多文件 服务端只能接收得到一条数据 h5用相同代码没有问题

let fileList = this.$refs.uUpload.lists;  
                    for (var i = 0; i < fileList.length; i++) {  
                        var url=fileList[i].url;  
                        this.files.push({  
                            name:"file:"+url,  
                            uri:url,  
                        });  
                        console.log("uri:"+url);  
                    }  
                    this.uploadFileServer();  
                }
