java - 如何使用java存储从php文件检索的数据

Question

我的问题是我们如何使用java在网络上存储来自php文件的数据(我可以查看 php 文件，但无法将其存储到我的数组变量中)。愿这有利于他人。

//http://sampleonly.com.my/getInfo.php //this url is not exist. just for example

<?php
echo("Ridzuan");
echo("split");
echo("Malaysia");
echo("split");
?>
// i want to get the echo "Ridzuan" and "Malaysia". i dont want echo "split".

下面是我当前的代码

    URL connectURL = new URL("http://sampleonly.com.my/getInfo.php");
    BufferedReader in = new BufferedReader(
    new InputStreamReader(connectURL.openStream()));

    String inputLine;
    while ((inputLine = in.readLine()) != null)
        System.out.println(inputLine);

        //array below should store input from .php file after i thrown "split" text
        String[] strArray2 = inputLine.split(Pattern.quote("split"));

    in.close();

错误输出:

Exception in thread "main" java.lang.NullPointerException

我引用过这个问题，Retrieving info from a file但对理解代码感到困惑。也许这里的任何好人都可以为我提供有关如何将 php 文件中的 echo 数据存储到我的 java 数组变量的有效代码。

提前感谢大家。

回答归功于 JJPA

    URL connectURL = new URL("http://vmalloc.in/so.php");
    BufferedReader in = new BufferedReader(
    new InputStreamReader(connectURL.openStream()));

    String inputLine;
    StringBuilder sb = new StringBuilder();
    while ((inputLine = in.readLine()) != null){     
        System.out.println(inputLine);
        sb.append(inputLine);
    }
    String[] strArray2 = sb.toString().split(Pattern.quote("split"));
    System.out.println(strArray2[0]);
    System.out.println(strArray2[1]);

    in.close();

输出结果:

    Ridzuan
    Malaysia  

正如我所愿

是的，您应该在 inputLine 中得到该异常。要知道我建议您调试代码。

作为解决方案，请尝试以下代码。

 URL connectURL = new URL("http://vmalloc.in/so.php");
    BufferedReader in = new BufferedReader(new InputStreamReader(
            connectURL.openStream()));

    String inputLine;
    StringBuilder sb = new StringBuilder();
    while ((inputLine = in.readLine()) != null) {
        System.out.println(inputLine);
        sb.append(inputLine);
    }
    // array below should store input from .php file after i thrown "split"
    // text
    String[] strArray2 = sb.toString().split("split");
    System.out.println(strArray2);
    in.close();
