从客户端到服务器接收字符串值

Question

我正在与yii-2 php一起在Android上工作。 从我的app我使用api调用将一些照片发送到文件中。 与此同时，我还发送了一个参考号，如下所示。

@Multipart
@POST("installation/photo/save")
Call<ApiResponse> uploadImage(@Header("Authorization") String token, @Part("ref_no") RequestBody ref_no, @Part MultipartBody.Part file);

调用如下所示初始化

Retrofit retrofit = RetrofitClient.getClient();

RetrofitInterface retrofitInterface = retrofit.create(RetrofitInterface.class);

RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);

MultipartBody.Part body = MultipartBody.Part.createFormData("uploaded_file", file.getName(), requestFile);

RequestBody ref_no = createPartFromString("<ref_no>");

ref_no = createPartFromString(installationDetails.getReferenceNo());

Call<ApiResponse> call = retrofitInterface.uploadImage("Bearer " + Common.getAuthKey(mContext),ref_no, body);

            call.enqueue(new Callback<ApiResponse>() {
                @Override
                public void onResponse(Call<ApiResponse> call, Response<ApiResponse> response) {
                    if (response.isSuccessful()) {

                        Log.d(TAG, response.body().getStatus());

                        if (response.body().getStatus().equals("OK")) {

                            snapManager.updateSnapStatus(AssetsManagementContract.SnapEntry.COLUMN_SITE_SNAP, snap.getSnapName(), Constants.SNAP_SYNCED);
                            Intent broadcastSyc = new Intent();
                            broadcastSyc.setAction(Common.GetSyncImageAction());
                            broadcastSyc.putExtra("STATUS", true);
                            mContext.sendBroadcast(broadcastSyc);
                            sendImage(mContext);

                        }
                        else{
                            snapManager.updateSnapStatus(AssetsManagementContract.SnapEntry.COLUMN_SITE_SNAP, snap.getSnapName(), Constants.SNAP_CLOSED);
                        }

                    } else {
                        snapManager.updateSnapStatus(AssetsManagementContract.SnapEntry.COLUMN_SITE_SNAP, snap.getSnapName(), Constants.SNAP_CLOSED);
                        Log.d(TAG, "Error");
                    }
                }

应用程序的工作

1. 用户记下安装细节并拍照
2. 在关闭表单时，两个API称为i）API，用于将安装数据保存/上传到服务器； ii）API，用于将映像保存/上传到服务器。

当安装API响应返回OK时，将上传图像。

OkHttp日志

当图像被推送到下面的服务器时， ok http的调用

服务器端

在下面的服务器端是用于保存图像的API代码。

public function actionSavephoto()
{
    try {
        $count = 0;
        foreach ($_FILES as $f) {
            $dd = pathinfo($f['name']);
            if (!isset($dd['extension']) || !in_array($dd['extension'], array('jpg', 'png', 'gif'))) {
                return ['status' => 'ERROR', 'uploaded_files' => $count, 'message' => 'Invalid File'];
                break;
            }
            if (move_uploaded_file($f['tmp_name'], Installations::UPLOAD_FOLDER . $f['name'])) {
                $count++;
                return ['status' => 'OK', 'uploaded_files' => $count];
                break;
            } else {
                return ['status' => 'ERROR', 'uploaded_files' => $count];
                break;
            }

        }

    } catch (Exception $x) {
        return ['status' => 'ERROR', 'message' => $x->getMessage()];
    }
}

以下var_dump($dd)之后的响应是生成的响应。

array(4) {
  ["dirname"]=>
   string(1) "."
   ["basename"]=>
   string(37) "28372230019211U_1517370655_site_1.jpg"
   ["extension"]=>
     string(3) "jpg"
   ["filename"]=>
   string(33) "28372230019211U_1517370655_site_1"
  }

对此，没有reference number 。 如何在服务器端获取参考号？

任何帮助将不胜感激。

Answer 1

检查调用后服务器端是否存在$_POST['ref_no'] 。
