fultter中使用dio实现网络上传总结

在本文中主要分享Flutter中的Dio文件实现上传并实现进度监听

///手机中的图片 String localImagePath ="/storage/emulated/0/Download/17306285.jpg"; ///上传的服务器地址 String netUploadUrl = "http://192.168.0.102:8080/fileupload";

///dio 实现文件上传 void fileUplod() async{ ///创建Dio Dio dio = new Dio();

Map map = Map(); map["auth"]="12345"; map["file"] = await MultipartFile.fromFile(localImagePath,filename: "xxx23.png"); ///通过FormData FormData formData = FormData.fromMap(map); ///发送post Response response = await dio.post(netUploadUrl, data: formData, ///这里是发送请求回调函数 ///[progress] 当前的进度 ///[total] 总进度 onSendProgress: (int progress, int total) { print("当前进度是 $progress 总进度是 $total"); },); ///服务器响应结果 var data = response.data;

}
