Question

我在android上创建了http服务。现在我正在尝试让HttpService向浏览器显示一些图像。我在浏览器中写了一个url（例如http://127.0.0.1:6789/home.html（我玩模拟器））。 http服务发送给我html如下：

<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> 
<title>File Upload</title> 
</head> 
<body> 
<td><img src='127.0.0.1:6789/1.png'/></td><br>
<td><img src='127.0.0.1:6789/2.png'/></td><br>
</body>

服务器端的一些代码是：

/*some variables*/    
private static final String IMAGE_PATTERN = "/*.png";
/*some code*/
registry.register(IMAGE_PATTERN, new ImageCommandHandler(context));

ImageCommandHandler：

@Override
public void handle(HttpRequest request, HttpResponse response,
    HttpContext httpContext) throws HttpException, IOException {         
    final InputStream is = GetInpuStreamFromResource(getContext(), 
            R.drawable.back);

    HttpEntity entity = new EntityTemplate(new ContentProducer() {
        public void writeTo(final OutputStream outstream) throws IOException {
            int bufSize = 0;
            byte[] buf = new byte[32768];
            while(-1!=(bufSize=is.read(buf))){
                outstream.write(buf,0,bufSize);
            }
            outstream.flush();
            outstream.close();
            is.close();
        }
    });
    response.setHeader("Content-Type", "image/*");      
    response.setEntity(entity);

或其他方式

@Override
public void handle(HttpRequest request, HttpResponse response,
    HttpContext httpContext) throws HttpException, IOException {

    final File f= new File("/sdcard/Tulips.jpg");       
    String contentType = URLConnection.guessContentTypeFromName(f.getAbsolutePath());
    FileEntity entity = new FileEntity(f, contentType);     
    response.setHeader("Content-Type",  contentType);
    response.setEntity(entity);
}

我已经尝试过两种方式，但无论如何都没有任何图像！它出什么问题了？我如何使用JavaScript的文件？感谢。

它完美无缺！我的错误是我写的：

<img src='127.0.0.1:6789/2.png'/>

但它返回空白页面，因为我错过了 http：// 。

我应该写如下：

<img src='http://127.0.0.1:6789/2.png'/>

感谢。
