How to set relative configuration file for my name-password AP?

Question

I would like to connect my RPi3 with wifi attached. I can scan all APs in my office using command "iwlist wlan0 scan". But I can't find IP address at response of ifconfig wlan0. I can connect to an AP using name/password at Windows. How can I connect to that AP and get IP address using DHCP. I set my /etc/network/interfaces:

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
sudo wpa_supplicant /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

content of /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant/wpa_supplicant.conf
update_config=1

network={
ssid="MiTAC-Wifi1"
key_mgmt=IEEE8021X
eap=PEAP
phase2="auth=MSCHAPV2"
identity="stan.huang"
password="rasp7890"
}

I doesn't work. How should I do with it?

You are using old deprecated settings for WiFi. I don't know where do you get this. With Raspberry Pi OS, WiFi is working out of the box. You only have to use the right settings. I suggest you start over again with a fresh flashed Raspberry Pi OS image of your choice. Then follow the official documentation for Wireless connectivity in the Raspberry Pi Desktop or Setting up a wireless LAN via the command line.
