import java.io.dataoutputstream;
import java.io.ioexception;
import java.io.inputstreamreader;
import java.net.httpurlconnection;
import java.net.url;

	//接口
	private final static string url = "https://console.tim.qq.com/v4/im_open_login_svc/account_import?";
	
	
	
	
	/**
	 * @param args

	public static void main(string[] args) throws ioexception {
