的第一行是
BufferedReader in = new BufferedReader ( new InputStreamReader ( conn.getInputStream ( ) ) ) ;
我不知道我做错了什么。使用HTTP客户端。下面是一个示例代码

reqEntity.addPart("file1", bin);

httppost.setEntity(reqEntity);
System.out.println("executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
if (resEntity != null) {
System.out.println("Response content length: " + resEntity.getContentLength());
InputStream is = resEntity.getContent();
if (is != null) {

char[] buffer = new char[1024];
try {

}
} finally {
is.close();
}
System.out.println("Response content: "+writer.toString());
} else {
System.out.println("Response nothing: ");
}
}
EntityUtils.consume(resEntity);
} finally {
try { httpclient.getConnectionManager().shutdown(); } catch (Exception ignore) {}
}
}
