android – 如何通过套接字读取HTTP响应？

我正在尝试在 Android设备上创建http代理服务器.当我尝试从http服务器(example1.com)读取响应(example1.com包含头文件中的content-length)
如果http服务器包含content-length,那么我将从content-length读取字节
否则我读了所有的响应字节

byte [] bytes = IoUtils.toByteArray(inFromServer);

问题是,当响应包含content-length的响应时
快速阅读
如果响应不包含content-length,则响应缓慢读取.

这是我的代码

DataInputStream in = new DataInputStream(inFromServer);
        //BufferedReader br = new BufferedReader(new InputStreamReader(in));
        String line = "";
        String str = "";
        Integer len = 0;
        while(true) {
            line = in.readLine();
            if  (line.indexOf("Content-Length") != -1)
            {
                len = Integer.parseInt( line.split("\\D+")[1] );
                //System.out.println("LINEE="+len);
            }

            out.println(linE);
            str = str + line + '\n';
            if(line.isEmpty())  break;
        }
        int i = Integer.valueOf(len);
        String body= "";
        System.out.println("i="+i);
        if (i>0) {
            byte[] buf = new byte[i];
            in.readFully(buf);
            out.write(buf);
            for (byte b:buf) {
                body = body + (char)b;
            }

        }else{

            byte[] bytes = IoUtils.toByteArray(inFromServer);
            out.write(bytes);
        }

out-outStream到浏览器

// Get server response
int responseCode = connection.getResponseCode();
if (responseCode == 200) {
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.geTinputStream()));
    String line;
    StringBuilder builder = new StringBuilder();
    while ((line = reader.readLine()) != null) {
        builder.append(linE);
    }
    String response = builder.toString()
    // Handle response...
}
