java怎么拿到PHP的数据

java获取php数据的方法：

推荐：php服务器

PHP文件：

readLogs(self::LOG_PATH,self::PAGES);
    $json=array();
    for($i=0;$i$i+1,"msg"=>urlencode($line));
    }
    $str=stripslashes(urldecode(json_encode($result)));
    echo $str;
  }
   
  
  private function readLogs($filePath,$num=20){
    $fp = fopen($filePath,"r");
    $pos = -2; 
    $eof = ""; 
    $head = false;  //当总行数小于Num时，判断是否到第一行了 
    $lines = array(); 
    while($num>0){ 
      while($eof != "
"){ 
        if(fseek($fp, $pos, SEEK_END)==0){  //fseek成功返回0，失败返回-1 
          $eof = fgetc($fp); 
          $pos--; 
        }else{                //当到达第一行，行首时，设置$pos失败 
          fseek($fp,0,SEEK_SET); 
          $head = true;          //到达文件头部，开关打开 
          break; 
        } 
          
      } 
      array_unshift($lines,fgets($fp)); 
      if($head){ break; }         //这一句，只能放上一句后，因为到文件头后，把第一行读取出来再跳出整个循环 
      $eof = ""; 
      $num--; 
    } 
    fclose($fp); 
    return array_reverse($lines); 
  }
}
Test::main();

java文件：

import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
 
import org.json.JSONArray;
import org.json.JSONObject;
 
public class ReadLogs {
  public static void main(String[] args) throws Exception {
    URL url = new URL("http://localhost/test.php?action=showApacheLogs");
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setConnectTimeout(10000);
    conn.setRequestMethod("GET");
    conn.setDoInput(true);
    conn.setDoOutput(true);
 
 
    // 输出返回结果
    InputStream input = conn.getInputStream();
    int resLen =0;
    byte[] res = new byte[1024];
    StringBuilder sb=new StringBuilder();
    while((resLen=input.read(res))!=-1){
      sb.append(new String(res, 0, resLen));
    }
     
    String jsonStr=sb.toString();
    //String转换成JSON
    JSONArray jsonArray=new JSONArray(jsonStr);
    for(int i=0;i
