我查看过FineUploader文档，想要问社区，以防万一我错过了。需要允许用户上传CSV文件，但希望检查CSV中的标题以确保它们符合要求。这是在FineUploader设置中执行此操作的方法吗？
例如，确保用户上传的CSV具有名字，姓氏，地址，电话的列标题。如果它与那些列标题不匹配，则返回错误消息。谢谢！

这种类型的自定义验证完全为什么custom validation回调被添加到Fine Uploader中。在您的情况下，由于您需要访问 using (var file = new StreamWriter("c:\\Test\\" + DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".csv"))
{
file.Write("Com Stat,");
file.Write("Trip Stat,");
file.WriteLine("Voltage");
string ComRead = null;
string TripRead = null;
string VoltRead = null;
CBox1.BackColor = Color.Green;
CBox2.BackColor = Color.Green;
CBox3.BackColor = Color.Red;
CBox4.BackColor = Color.Green;
CBox5.BackColor = Color.Green;
CBox6.BackColor = Color.Green;
CBox7.BackColor = Color.Green;
CBox8.BackColor = Color.Red;
CBox9.BackColor = Color.Green;
CBox10.BackColor = Color.Green;
TBox1.BackColor = Color.Red;
TBox2.BackColor = Color.Green;
TBox3.BackColor = Color.Green;
TBox4.BackColor = Color.Green;
TBox5.BackColor = Color.Green;
TBox6.BackColor = Color.Green;
TBox7.BackColor = Color.Green;
TBox8.BackColor = Color.Green;
TBox9.BackColor = Color.Red;
TBox10.BackColor = Color.Green;
VBox1.Text = "10.0 V";
VBox2.Text = "5.0 V";
VBox3.Text = "---";
VBox4.Text = "5.0 V";
VBox5.Text = "3.0 V";
VBox6.Text = "5.0 V";
VBox7.Text = "5.0 V";
VBox8.Text = "---";
VBox9.Text = "0.0 V";
VBox10.Text = "5.0 V";
for (int i = 1; i < 11; i++)
{
foreach (var richBox in this.Controls.OfType<RichTextBox>())
{
if ((richBox.Name.StartsWith("CBox" + i)) && (richBox.BackColor == Color.Green))
{
ComRead = "True";
}
else
{
ComRead = "False";
}
file.Write(ComRead + ",");
if ((richBox.Name.StartsWith("TBox" + i)) && (richBox.BackColor == Color.Green))
{
TripRead = "True";
}
else
{
TripRead = "False";
}
file.Write(TripRead + ",");
if (richBox.Name.StartsWith("VBox" + i))
{
VoltRead = richBox.Text;
}
file.WriteLine(VoltRead);
}
}
file.Close();
MessageBox.Show("Demo Complete");
}
或File，因此您可以提交返回Blob的{{3}}。在此回调中，您可以确定该文件是否为CSV。如果是，您可以使用an onSubmit callback读取客户端文件，解析文件以确定它是否符合您的要求。如果是这样，只需履行返回的承诺。否则，拒绝它。请注意，您可以通过FileReader获取对文件ID的基础Promise或File的访问权限。
