如何从远程php脚本响应中获取二进制文件？ [英] How to get a binary file from a remote php script response?

问题描述

我正在调用一个脚本，它给我一个带二进制数据的二进制文件（12345.cl）。脚本完成了，它正在工作，如果我将它粘贴到导航器上，我会得到二进制文件。

I'm calling a script that gives me a binary file (12345.cl), with binary data. The script is done, and it's working, if I paste it on the navigator I get the binary file.

现在我遇到了一个问题：我如何转换响应脚本到二进制资源中以在我的应用程序中使用它？

Now I have a problem: How I transform the response of the script into a binary resource to use it in my app?

目前，我有这样的代码：

For the moment, i have this code:

 public void decodeStream( String mURL ){  
        BufferedInputStream bis = new BufferedInputStream(new URL(mURL).openStream(), BUFFER_IO_SIZE);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        BufferedOutputStream bos = new BufferedOutputStream(baos, BUFFER_IO_SIZE);
        copy(bis, bos);
        bos.flush();

然后，我有一个带响应的BufferedOutputStream，但我不知道如何将其转换为使用它的二进制资源

Then, I have a BufferedOutputStream with the response, but I don't know how to transform it into a binary resource to use it

我需要获取带文件的datainputstream但我不知道如何实现它

I need to obtain a datainputstream with the file but I don't know how to achieve it

推荐答案

您可以使用以下代码：

public void decodeStream( String mURL, String ofile ) throws Exception {
    InputStream in = null;
    FileOutputStream out = null;
    try {
        URL url = new URL(mURL);
        URLConnection urlConn = url.openConnection();
        in = urlConn.getInputStream();
        out = new FileOutputStream(ofile);
        int c;
        byte[] b = new byte[1024];
        while ((c = in.read(b)) != -1)
            out.write(b, 0, c);
    } finally {
        if (in != null)
            in.close();
        if (out != null)
            out.close();
    }
}
