我有一种方法可以将数据转换为字节数组，我必须将其发布到 php 网站。我现在要使用 java 套接字。准备如果我这样做了，我会在这里添加

它是字节 [] 方法的数据，我在PDF 中找到它到字节数组，反之亦然

public static byte[] readFully(InputStream stream) throws IOException
    {
byte[] buffer = new byte[8192];
ByteArrayOutputStream baos = new ByteArrayOutputStream();

int bytesRead;
while ((bytesRead = stream.read(buffer)) != -1)
{
    baos.write(buffer, 0, bytesRead);
}
return baos.toByteArray();
    }
public static byte[] loadFile(String sourcePath) throws IOException
{
InputStream inputStream = null;
try 
{
    inputStream = new FileInputStream(sourcePath);
    return readFully(inputStream);
} 
finally
{
    if (inputStream != null)
    {
        inputStream.close();
    }
}
}

在这里如何将字节发布到 php 网站...

public  static void postMybyte (String out)
{
    try {
            // Construct data
            String data = URLEncoder.encode(out, "UTF-8") ;

            // Send data
            URL url = new URL("");
            URLConnection conn = url.openConnection();
            conn.setDoOutput(true);
            OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
            wr.write(data);
            wr.flush();

            // Get the response
           BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            while ((line = rd.readLine()) != null) {
               System.out.println(" --->>>>"+line);
            }
            wr.close();
            rd.close();
    } catch (Exception e) 
    {

    }
}
