我正在使用这个java程序从我的程序中的指定URL读取csv文件内容,问题是它不能获取最后64条记录,即它将所有记录都记录到我指定的myHello中.csv文件,除了最后64.Plz帮助。
package com.aamir;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class TestGetCSV {
public static void main(String[] args) {
try {
URL url12 = new URL("https://wd5-impl-services1.workday.com/ccx/service/customreport2//ISU-YINT061-ProjectsFE/YINT061.05-OpenText?format=csv" );
URLConnection uc = url12.openConnection();
String userpass = "username" + ":" + "password";
String basicAuth = "Basic " + javax.xml.bind.DatatypeConverter.printBase64Binary(userpass.getBytes());
uc.setRequestProperty ("Authorization", basicAuth);
/* HttpURLConnection conn = (HttpURLConnection)uc;
conn.setInstanceFollowRedirects( false );
*/
InputStreamReader inStream = new InputStreamReader(uc.getInputStream());
BufferedReader buff= new BufferedReader(inStream);
String content2 = null;
BufferedWriter bf = new BufferedWriter(new FileWriter("D:/myHello.csv"));
while ((content2 = buff.readLine()) != null) {
bf.write(content2);
content2 = buff.readLine();
bf.flush();
}
}
catch (Exception e){
e.printStackTrace();
System.out.print("KHONG TAI DUOC DU LIEU");
}
System.out.println("done");
}
}
答案 0 :(得分:1)
你是" double"从每个循环中的BufferedReader消耗。你为每个循环调用readLine()
两次,但只写一次(所以你要删除每一行)。
