我正在使用Express和Node-pg将Excel文件导入Postgres数据库
目前,我正在遍历excel行并为每一行执行一个插入操作,但是我觉得这不是正确的方法:
workbook.xlsx.readFile(excel_file).then(function () {
// get the first worksheet
var worksheet = workbook.getWorksheet(1);
// Loop through all rows
worksheet.eachRow(function (row, rowNumber) {
// Commit to DB only from line 2 and up. We want to exclude headers from excel file
if (rowNumber > 1) {
// Loop through all values and build array to pass to DB function
row.eachCell(function (cell, colNumber) {

// Add the user id from session to the array
arrSQLParams.push(user);

我正在尝试从片段中使用 Ucrop。我面临的问题是 onActivityresult 没有收到,requestCode == UCrop.REQUEST_CROP因此没有执行我需要对图像执行的操作。我四处寻找教程,但我没有找到任何教程。
以下是使用 UCrop 的片段代码:
public class FragmentSettingsTabImage extends Fragment {
private String TAG = "----->";
Tools t;
private String currentPhotoPath;
private final int REQUEST_TAKE_PHOTO = 1;
private final int CAMERA_PERMISSIONS = 2;
private ImageView imgTabImageDriver;
private Button btnSettingsSaveImage;
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
